## HPE security service NOTE It is possible that some properties or resources described in this section are not implemented in HPE iLO 4 and iLO 5. The `HpeSecurityService` subsystem is the main entry point to the different security mechanisms protecting the iLO and the platform (chassis and components). The integrity of components (i.e. add-on cards, adapters) is discussed in the [iLO and the SPDM](/docs/redfishservices/ilos/supplementdocuments/spdm/) section. Operating system protection is described in the [HTTPS Boot TLS configuration](/docs/redfishservices/ilos/supplementdocuments/biostlsconf/) and the [Secure Boot Databases](/docs/concepts/securebootdatabases/) sections. ## iLO Security State Starting with HPE iLO 5, the `SecurityState` property can be modified. The following example retrieves the possible values from an HPE iLO 5 or 6 and an HPE iLO 7, using [HPE iLOrest](/docs/redfishclients/ilorest-userguide) and cURL Redfish clients. iLOrest ```shell ilorest login ilo-ip -u ilo-user -p password ilorest select HpeSecurityService. ilorest info SecurityState ilorest logout ``` iLOrest output (iLO 5 or 6) ```text NAME SecurityState DESCRIPTION The operational security level of this Manager.

Any unsupported transition results in an error. Refer to the next paragraph for allowed transitions - `SynergySecurityMode` only concerns Synergy Composers. - `Wipe` is a transition state that cannot be set. The following example retrieves the current security state using HPE iLOrest and cURL. iLOrest ```shell ilorest login ilo-ip -u ilo-user -p password ilorest select HpeSecurityService. ilorest get SecurityState --json ilorest logout ``` cURL ```shell curl --insecure --silent --user ilo-user:password \ 'https://ilo-ip/redfish/v1/Managers/1/SecurityService/' | \ jq '{SecurityState}' ``` Response ```json { "SecurityState": "Production" } ``` The following example transitions from `Production` to `HighSecurity` iLOrest ```shell ilorest login ilo-ip -u ilo-user -p password ilorest select HpeSecurityService. ilorest set SecurityState="HighSecurity" ilorest commit ilorest logout ``` cURL ```shell curl --insecure --silent --user ilo-user:password \ --header 'Content-Type: application/json' \ --request PATCH --location 'https://ilo-ip/redfish/v1/Managers/1/SecurityService/' \ --data '{"SecurityState": "HighSecurity"}' ``` Response ```json { "error": { "code": "iLO.0.10.ExtendedInfo", "message": "See @Message.ExtendedInfo for more information.", "@Message.ExtendedInfo": [ { "MessageId": "iLO.2.21.ResetInProgress" } ] } } ``` ### Allowed Transitions #### HPE iLO 5 and 6 | Transition | Notes | | --- | --- | | Production <--> HighSecurity | You may transition freely between Production and High Security states, subject to authentication and privileges. | | Production or HighSecurity --> FIPS | You may transition into FIPS mode. Transitions out of FIPS mode are complex and beyond the scope of the RESTful API. | #### HPE iLO 7 | Transition | Notes | | --- | --- | | Secure Standard --> FIPS | You may transition into FIPS mode. Transitions out of FIPS mode are complex and beyond the scope of the RESTful API. | ### In-band management of iLO 5 and 6 This paragraph concerns only HPE iLO 5 and iLO 6. Refer to the [next paragraph](#transitioning-to-hpe-ilo-7) for [in-band management](/docs/redfishservices/ilos/supplementdocuments/vnic#in-band-management) of HPE iLO 7 and later. With iLO 5 and 6 in `Production` security state , privileged OS users (i.e. root, Administrator) can communicate with their local iLO ([in-band management](/docs/redfishservices/ilos/supplementdocuments/vnic#in-band-management)) via the [Channel Interface (CHIF)](/docs/etc/glossaryterms/) without supplying any credential, only when the `RequireHostAuthentication` property is set to `False` (default value). With iLO 5 and 6 in `HighSecurity` state , privileged OS users (i.e. root, Administrator) can communicate with their local iLO via [CHIF](/docs/etc/glossaryterms/) without supplying any credential when the `RequireHostAuthentication` property is set to `False`. With iLO 5 and 6 in `FIPS` security state and higher, all OS users must provide valid credentials when willing to communicate with local iLO (in-band) via [CHIF](/docs/etc/glossaryterms/) NOTES - In `FIPS` security state, the `RequireHostAuthentication` property is set to `true` and cannot be modified. - The HPE OEM `RequireHostAuthentication` property has been removed in HPE iLO 7. Refer to the [next paragraph](#transitioning-to-hpe-ilo-7) for more info concerning HPE iLO 7. In iLO 5 and 6 based servers, regardless the value of the security state , OS users must supply valid credentials when willing to communicate with local iLO (in-band) via the [Virtual NIC](/docs/redfishservices/ilos/supplementdocuments/vnic). Tip Use `ilorest login --force_vnic -u ilo-user -p ilo-password` to open an in-band Redfish session to the local iLO. The following example retrieves the value of the `SecurityState` and the `RequireHostAuthentication` properties with cURL and iLOrest from a remote iLO 6. cURL ```shell curl --insecure --silent --user ilo-user:password \ 'https://ilo-ip/redfish/v1/Managers/1/SecurityService/' | jq '{SecurityState}' { "SecurityState": "HighSecurity" } curl --insecure --silent --user ilo-user:password \ 'https://ilo-ip/redfish/v1/Managers/1/' | jq '.Oem.Hpe | {RequireHostAuthentication}' { "RequireHostAuthentication": true } ``` iLOrest ```shell ilorest login ilo-ip -u ilo-user -p password ilorest get SecurityState --select HpeSecurityService. --json { "SecurityState": "HighSecurity" } ilorest get Oem/Hpe/RequireHostAuthentication --select Manager. --json { "Oem": { "Hpe": { "RequireHostAuthentication": true } } } ``` From the local OS of a system with its iLO in `HighSecurity` state and `RequireHostAuthentication` set to `true`, when logged as a privileged user (root), the following example tries to modify the value of a property using iLOrest and without providing any credential. iLOrest in verbose mode ```shell root> whoami root root> ilorest --verbose get Oem/Hpe/RequireHostAuthentication --select Manager. Local login initiated... High security mode [4] or Host Authentication has been enabled. Please provide valid credentials. iLORest return code: 75 ``` The following example disables host authentication from a remote system using cURL and iLOrest. cURL ```shell curl --insecure --silent --user ilo-user:password \ --header 'Content-Type: Application/json' \ --request PATCH \ --location 'https://ilo-ip/redfish/v1/Managers/1/' \ --data '{"Oem": {"Hpe": {"RequireHostAuthentication": false}}}' ``` iLOrest ```shell ilorest login ilo-ip -u ilo-user -p password ilorest select Manager. ilorest set Oem/Hpe/RequireHostAuthentication=false ilorest commit ilorest logout ``` Body Response ```json { "error": { "code": "iLO.0.10.ExtendedInfo", "message": "See @Message.ExtendedInfo for more information.", "@Message.ExtendedInfo": [ { "MessageId": "Base.1.17.Success" } ] } } ``` From the OS of a system with iLO in `HighSecurity` state and `RequireHostAuthentication` set to `false`, logged as a privileged OS user (root), the following example can retrieve a property value without supplying any credential. iLOrest ```shell root> whoami root root> ilorest get Oem/Hpe/RequireHostAuthentication --select Manager. Discovering data...Done Oem= Hpe= RequireHostAuthentication=False root> ilorest logout logging session out. ``` NOTE As a reminder, whatever the security state of iLO, a non-privileged OS user cannot access the local iLO via CHIF or [Virtual NIC](/docs/redfishservices/ilos/supplementdocuments/vnic) without formal authentication. The following example illustrates this assertion. iLOrest ```shell user> whoami user user>ilorest --verbose get Oem/Hpe/RequireHostAuthentication --select Manager. Local login initiated... Both remote and local mode is accessible when RESTful Interface Tool is run as administrator. Only remote mode is available for non-admin user groups. iLORest return code: 5 ``` When performing local (via CHIF) BIOS configuration changes, the following conditions apply: | Local REST Access | No BIOS Password | BIOS Password Set | | --- | --- | --- | | Production Mode | **No authorization required** | **Requires BIOS Configuration Privilege** | | High Security Mode | Requires BIOS Configuration Privilege | Requires BIOS Configuration Privilege | | Remote REST Access | No BIOS Password | BIOS Password Set | | --- | --- | --- | | Production Mode | **Requires BIOS Configuration Privilege** | Requires BIOS Configuration Privilege | | High Security Mode | Requires BIOS Configuration Privilege | Requires BIOS Configuration Privilege | Refer to the [Roles and privileges](/docs/redfishservices/ilos/supplementdocuments/managingusers/#roles-and-privileges) paragraph for more detail on this topic. NOTE HPE iLO is not validating against the BIOS setup password, but is using the presence of the BIOS password to require BIOS Configuration Privilege. ## Transitioning to HPE iLO 7 With the introduction of HPE iLO 7, the HPE Channel Interface ([CHIF](/docs/etc/glossaryterms)) between the OS and iLO has been removed. As a consequence, [in-band management](/docs/redfishservices/ilos/supplementdocuments/vnic#in-band-management) of iLO 7 based servers can only occur via the [Virtual NIC](/docs/redfishservices/ilos/supplementdocuments/vnic) (vNIC). Virtual NIC is more restrictive in terms of authentication than CHIF; Host Redfish clients must always [authenticate](https://servermanagementportal.ext.hpe.com/docs/concepts/redfishauthentication/) before being able to perform Redfish requests through this communication path. This is not the case with iLO 5 and iLO 6 as explained [above](#in-band-management-of-ilo-5-and-6). NOTE In addition to the removal of the [CHIF](/docs/etc/glossaryterms) between OS and iLO 7 (and later), the `RequireHostAuthentication` property has also been removed. ### Application accounts With HPE iLO 7, the enforcement of authentication before any [in-band](/docs/redfishservices/ilos/supplementdocuments/vnic#in-band-management) communication is also valid for applications running in the host. Host applications willing to use vNIC to communicate with iLO can be scripts, binary programs like [iLOrest](https://servermanagementportal.ext.hpe.com/docs/redfishclients/ilorest-userguide) , system services like the HPE Agentless Management Service (AMS) or asynchronously launched applications like the Software Update Tool ( iSUT) and the HPE Smart Update Manager ( SUM). In order to provide those applications an in-band access to iLO without any human interaction and without the need for retrieving credentials from unsecure locations, a companion application account and an associated application token can be created during the application installation or at a later time. Application accounts are slightly different from iLO user accounts. This is why they are described in a specific HPE OEM schema . Application tokens are securely stored in the Truted Platform Module (TPM) of the server. NOTES - Application accounts are applicable **only** for HPE applications. - Application accounts and application tokens are tightly coupled. - The term "application account" may refer to both objects: "application account" and "application token". It may also refer to the "application token" only. - Similarly, the term "application token" may refer to both objects: "application token" and "application account". It may also refer to the "application account" only. The creation of application accounts (and associated application tokens) is performed only once, using the credentials of an already existing iLO user. Upon successful identification, iLO creates the application accounts and sends back the application token that the application stores securely in the TPM. Then, when applications need to [in-band](/docs/redfishservices/ilos/supplementdocuments/vnic#in-band-management) communicate with iLO, they present their respective application token to the iLO that validates it and replies back with a Redfish session token. With this process, host applications don't need to wait for a human being or to fetch iLO user credentials from an insecure location to authenticate and create a Redfish session. Application accounts are listed in the standard `ManagerAccountCollection` collection . Application accounts are modeled in the OEM `HpeiLOAppAccount` extension schema. The following example retrieves the collection of application accounts present in a remote HPE iLO 7. iLOrest ```shell ilorest login ilo7-ip -u ilo-user -p password ilorest list Members --select ManagerAccountCollection. \ --filter @odata.id="/redfish/v1/AccountService/Oem*" \ --json { "Members": [ { "@odata.id": "/redfish/v1/AccountService/Oem/Hpe/AppAccounts/65605/" }, { "@odata.id": "/redfish/v1/AccountService/Oem/Hpe/AppAccounts/65606/" } ] } ``` cURL ```shell curl --insecure --silent --location -u ilo-user:password \ https://ilo7-ip/redfish/v1/AccountService/Oem/Hpe/AppAccounts/ | \ jq . { "@odata.id": "/redfish/v1/AccountService/Oem/Hpe/AppAccounts/65605/" } { "@odata.id": "/redfish/v1/AccountService/Oem/Hpe/AppAccounts/65606/" } ``` The following example retrieves the properties of the Agentless Management Service (AMS) application account, using iLOrest and cURL, and present in a remote HPE iLO 7. iLOrest ```shell ilorest login ilo7-ip -u ilo-user -p password ilorest list --select HpeiLOAppAccount --filter HostAppName="AMS" --json ilorest logout ``` cURL ```shell # NOTE: The {AppAccountId} has to be discovered programatically. # This could be done by expanding and parsoing the accounts found in # previous example. # curl --insecure --silent --location -u ilo-user:password \ https://ilo7-ip/redfish/v1/AccountService/Oem/Hpe/AppAccounts/{AppAccountId}/ | \ jq . ``` Response ```json { "@odata.context": "/redfish/v1/$metadata#HpeiLOAppAccount.HpeiLOAppAccount", "@odata.etag": "W/\"3800415391\"", "@odata.id": "/redfish/v1/AccountService/Oem/Hpe/AppAccounts/65606/", "@odata.type": "#HpeiLOAppAccount.v1_0_0.HpeiLOAppAccount", "Description": "iLO Application Account", "HostAppId": "******************************fea0", "HostAppName": "AMS", "Id": "65606", "Name": "Application Account", "Privileges": { "HostBIOSConfigPriv": false, "HostNICConfigPriv": false, "HostStorageConfigPriv": false, "LoginPriv": true, "RemoteConsolePriv": false, "SystemRecoveryConfigPriv": false, "UserConfigPriv": false, "VirtualMediaPriv": false, "VirtualPowerAndResetPriv": false, "iLOConfigPriv": true } } ``` NOTE The `privileges` object present in the Response tabulation of the previous example, has been inherited from the OEM account privileges of the iLO user whose credentials have been used to create this application account. Refer to the [next paragraph](#installing-hpe-host-applications) for more detail. ### Installing HPE host applications With the introduction of HPE iLO 7, the installation scripts of HPE applications needing [in-band](/docs/redfishservices/ilos/supplementdocuments/vnic#in-band-management) access iLO have the ability to create an associated application account within the underlying iLO. For this creation to happen, it is necessary to supply the credentials of an already existing iLO user, interactively or through system global variables. Refers to the examples below. #### Application account privileges The following table lists the minimum privileges required by HPE host applications to operate seamlessly trough [in-band](/docs/redfishservices/ilos/supplementdocuments/vnic#in-band-management) communication with the underlying iLO. TIP If you don't provide more privileges to the iLOrest application than the minimum ones listed below, iLOrest will not be able to modify properties in the Redfish tree. Use iLOrest [out-of-band management](/docs/redfishservices/ilos/supplementdocuments/vnic#out-of-band-management) with sufficient privileges to modify the properties that cannot be [in-band](/docs/redfishservices/ilos/supplementdocuments/vnic#in-band-management) modified. | Host application Name | Minimum required application account privileges | | --- | --- | | iLOrest | `LoginPriv`, `UserConfigPriv`, `iLOConfigPriv` | | AMS | `LoginPriv`, `UserConfigPriv`, `iLOConfigPriv` | | Smart Update Manager | `LoginPriv`, `UserConfigPriv`, `iLOConfigPriv`, `SystemRecoveryConfigPriv` | | Integrated Smart Update Tools | `LoginPriv`, `UserConfigPriv`, `iLOConfigPriv` | The following example creates an `ilorest-appuser` with `LoginPriv`, `UserConfigPriv` and `iLOConfigPriv` privileges. Refer to the iLOrest [user guide](/docs/redfishclients/ilorest-userguide/ilocommands/#iloaccounts-command) for the privileges numbering. Application user creation with iLOrest ```shell ilorest login ilo-ip -u ilo-user -p password ilorest iloaccounts add ilorest-appuser "iLOrest application user" passwordexample --addprivs 1,3,4 New iLO account ilorest-appuser is added successfully # View the just created user: ilorest get --select ManagerAccount. --refresh --filter UserName="ilorest-appuser" --json { "AccountTypes": [ "WebUI" ], "Description": "iLO User Account", "Enabled": true, "Id": "8", "Name": "User Account", "Oem": { "Hpe": { "LoginName": "iLOrest application user", "Privileges": { "HostBIOSConfigPriv": false, "HostNICConfigPriv": false, "HostStorageConfigPriv": false, "LoginPriv": true, "RemoteConsolePriv": false, "SystemRecoveryConfigPriv": false, "UserConfigPriv": true, "VirtualMediaPriv": false, "VirtualPowerAndResetPriv": false, "iLOConfigPriv": true }, "ServiceAccount": false } }, "Password": null, "PasswordChangeRequired": false, "RoleId": "Administrator", "UserName": "ilorest-appuser" } ilorest logout ``` #### Installation examples The following example shows an interactive installation of the iLOrest 6.0.0.0 RPM package in an HPE iLO 7 based Linux operating system, with the creation of a application account for further easy [in-band management](/docs/redfishservices/ilos/supplementdocuments/vnic#in-band-management). The credentials supplied for the creation of the application account are the ones of the user created in the previous example (`ilorest-appuser`). Interactive installation ```text whoami root rpm -ivh ilorest-6.0.0.0-29.x86_64.rpm warning: ilorest-6.0.0.0-29.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID 26c2b797: NOKEY Verifying... ################################# [100%] Preparing... ################################# [100%] Updating / installing... 1:ilorest-6.0.0.0-29 ################################# [100%] Unable to find an application account.

For more information application account, please refer to the documentation. Successfully created the application account. Application installed successfully. ilorest iloaccounts delete ilorest-appuser unset ILO_USERNAME ILO_PASSWORD ``` ### Managing application accounts The management of application accounts consists of three operations: create, check and delete. The creation can be performed during the installation of the application (previous example) or later, using the Command Line Interface (CLI) associated with the application (i.e. `amscli`, `ilorest`) The following example checks the existence of an application account for the Agentless Management Service and for iLOrest, using their respective CLI. amscli appaccount ```shell amscli appaccount check AppToken for AMS is found in TPM. ``` iLOrest appaccount ```shell ilorest appaccount exists --self Application account exists for this host application. ``` NOTES The iLOrest `appaccount` [command](/docs/redfishclients/ilorest-userguide/ilocommands/#appaccount-command) can only be used during an [in-band](/docs/redfishservices/ilos/supplementdocuments/vnic#in-band-management) session created with the help of its own application account and from an iLO 7 based (or later) operating system. The following example demonstrates the flexibility of iLOrest and its associated application account. Without supplying any iLO credentials, it logs out from any existing session, detects the underlying iLO type and then lists all the application accounts and their details. These operations are performed in the OS of an iLO 7 based server. iLOrest ```shell ilorest logout Logging session out. ilorest detectilo Detecting iLO for this server. iLO Type: 7 ilorest appaccount details --hostappid all Application Name: AMS Application Id: **fea0 App account exists in TPM: yes App account exists in iLO: yes Application Name: iLORest Application Id: **00b5 App account exists in TPM: yes App account exists in iLO: yes ``` The following example uses iLOrest to delete its own application account using the last four digits of its host application Id, found in previous example. Then, it checks for its own application account in verbose mode. The [return code](/docs/redfishclients/ilorest-userguide/errors/) is 143 (TOKEN_DOES_NOT_EXIST_ERROR), which is normal because both application account and associated token have just been deleted. The last step of the following example fails to retrieve all application account details because iLOrest could not create a Redfish session (error 143). iLOrest ```shell ilorest appaccount delete --hostappid 00b5 Application account has been deleted successfully. ilorest -vv appaccount exists --self Application account does not exist for this hostapp. iLORest return code: 143 ilorest -vv appaccount details --hostappid all ERROR : iLORest app account not found. Please create one using ilorest appaccount create to proceed. iLORest return code: 143 ``` The following example creates an in-band vNIC session for iLOrest, without using its application account (it has been deleted in previous example). Then, it tries to retrieves the details of all application accounts in underlying iLO 7. The failure is expected because the iLOrest Redfish session has not been created with the help of an application account, and the `ilorest appaccount` command can only be used during an in-band session created with the help of iLOrest's associated application account. iLOrest ```shell ilorest login --no_app_account -u ilo_user -p password Attempt to login with Vnic... Discovering data...Done ilorest -vv appaccount details --hostappid all ERROR : iLORest app account not found. Please create one using ilorest appaccount create to proceed. iLORest return code: 143 ``` The following example uses iLOrest to create its own application account. By supplying an iLO user (and password) with the [minimum iLO privileges](#installing-hpe-host-applications), iLOrest can open a Redfish session, and ask iLO to create the application account and send back the associated application token to be stored in the TPM. The second command can retrieve the details of all application accounts present in iLO, because the iLOrest Redfish session has been created with the help of its application account. iLOrest ```shell # Make sure iLOrest is logged out ilorest logout ilorest appaccount create --self -u ilorest-appuser -p password Application account has been generated and saved successfully. ilorest appaccount details --hostappid all Application Name: AMS Application Id: **fea0 App account exists in TPM: yes App account exists in iLO: yes Application Name: iLORest Application Id: **00b5 App account exists in TPM: yes App account exists in iLO: yes ``` ## iLO TLS versions management To provide a high degree of privacy and ensure authentication and data integrity in communications between clients (Web and Redfish) and iLO, it is possible to configure different versions of the Transport Layer Security (TLS) protocol using the `TLSVersion` property of the `HpeSecurityService` data type. TLS, formerly called Secure Socket Layer (SSL) is a standard from the Internet Engineering Task Force (IETF). This paragraph details the `TLSversion` property which displays the status (`Enabled` / `Disabled`) of the supported TLS versions and how they can be modified in the different security states. It corresponds to the `Security` -> `Encryption Settings` screen of the HPE iLO graphical user interface. HPE iLO Standard, that comes with every HPE ProLiant Gen11 or later server, gives customers the ability to configure servers in one of three security states (Production, High Security, and FIPS). With an iLO Advanced license, a fourth security state is available, providing the highest level encryption capabilities of CNSA. iLO features the following security states: 1. Production 2. High Security 3. FIPS (Federal Information Processing Standards) 4. CNSA (Commercial National Security Algorithm) NOTE - TLS versions 1.0 and 1.1 can be enabled or disabled only in Production mode. They are **disabled in higher security modes** such as High Security, FIPS, and CNSA. - Tools that do not support TLS 1.2 will not be able to - connect to iLO when TLS 1.0 and 1.1 are disabled. For more information on iLO security states, refer to the `iLO encryption settings` section in the HPE iLO User Guide ### Viewing status of TLS versions enabled/disabled The following example retrieves the status of TLS versions. GET Request ```text GET /redfish/v1/Managers/1/SecurityService/?$select=TLSVersion ``` Response body ```json { "@odata.context": "/redfish/v1/$metadata#HpeSecurityService.HpeSecurityService", "@odata.etag": "W/\"A7ED5344\"", "@odata.id": "/redfish/v1/Managers/1/SecurityService", "@odata.type": "#HpeSecurityService.v2_3_1.HpeSecurityService", "TLSVersion": { "TLS1_0": "Disabled", "TLS1_1": "Enabled", "TLS1_2": "Enabled" } } ``` ### Modifying the status of specific TLS versions TLS versions can only be modified when the iLO is in the `Production` security state. The following example retrieves the `SecurityState` property using a generic GET request and the iLOrest command line interface. Generic GET request ```text GET /redfish/v1/Managers/1/SecurityService/?$select=SecurityState ``` iLOrest ```bash ilorest login ilo-ip -u ilo-user -p password ilorest get SecurityState --json --selector HpeSecurityService. ilorest logout ``` iLOrest response body ```json { "SecurityState": "Production" } ``` Warning In iLO 6 v1.05 and iLO 6 v1.10, the TLSVersion properties are not PATCHable through Redfish. The workaround is to modify them through iLO GUI as explained in the *Enabling the Production security state* section of the iLO User Guide In iLO 6 v1.05 and v1.10, performing an update on TLS versions with a PATCH request and the enum values `Enabled` and `Disabled` returns an `iLO.2.15.PropertyValueBadParam` error. Enabling/disabling the TLS versions triggers an event and creates an alert for that event. The message arguments include TLS version being modified, its status, and the user who requested for the change for the alert. Updating TLS versions creates an entry in the [Security Logs](/docs/redfishservices/ilos/supplementdocuments/logservices/#security-logs). Remote event listener systems (i.e. HPE Compute Ops Management) are notified after [subscribing](/docs/concepts/redfishevents/) to the `iLOEvents` registry prefix. Examples of entries (Description) in the `Security Log` after performing `PATCH` on TLS versions: - `TLS Version 1.0 is Disabled by: username` - `TLS Version 1.0 is Enabled by: username` - `TLS Version 1.1 is Disabled by: username` - `TLS Version 1.1 is Enabled by: username` ## Enable/Disable weak iLO ciphers HPE iLO provides flexibility to enable/disable weaker encryption algorithms, and shorter key lengths in the `Production` [security state](/docs/redfishservices/ilos/supplementdocuments/securityservice/#ilo-security-state). Property `DisableWeakCiphers` has been added in iLO 5 version 3.01 and iLO 6 version 1.56 under the URI `/redfish/v1/Managers/1/SecurityService/` that supports Boolean values i.e.`{true}` and `{false}`. Performing a `PATCH` on this property enables/disables weak ciphers i.e. `TLS1.0` and `TLS1.1`. For example, `PATCH` on property `DisableWeakCiphers` with a `false` attribute enables weak ciphers whereas `true` disables weak ciphers resulting in disabling of the TLS support. Upon a successful `PATCH` operation, iLO resets and the updated values are seen in the next `GET` request on the same URI(`/redfish/v1/Managers/1/SecurityService/`). When `DisableWeakCiphers` is set to `{true}` `TLS1.0` and `TLS1.1` are not usable or configurable in iLO. When `DisableWeakCiphers` is set to `{false}` `TLS1.0` and `TLS1.1` can be configured to enable/disable as per your requirement. NOTE The property `DisableWeakCiphers` is only modifiable when the [Security State](/docs/redfishservices/ilos/supplementdocuments/securityservice/#ilo-security-state) is set as `Production` i.e. The Property won't be patched in the `SecurityService` URI when the iLO is operating in high security modes such as `FIPS` or `CNSA`. To disable weak ciphers perform `PATCH` PATCH request ```text PATCH /redfish/v1/Managers/1/SecurityService/ ``` PATCH Payload ```json { "DisableWeakCiphers" : true } ``` Generic GET request ```text GET /redfish/v1/Managers/1/SecurityService/ ``` GET response ```json { "@odata.context": "/redfish/v1/$metadata#HpeSecurityService.HpeSecurityService", "@odata.etag": "W/\"3E42B793\"", "@odata.id": "/redfish/v1/Managers/1/SecurityService/", "@odata.type": "#HpeSecurityService.v2_5_0.HpeSecurityService", "Id": "SecurityService", "ComponentIntegrityPolicy": "NoPolicy", "CurrentCipher": "ECDHE-RSA-AES256-GCM-SHA384", "DisableWeakCiphers": true, ...

PATCH Payload ```json { "DisableWeakCiphers" : false, "TLSVersion":{ "TLS1_0": "Enabled", "TLS1_1": "Enabled" } } ``` NOTE - Tools that use weak ciphers and key length less than 2048-bit will not be able to connect to iLO when `DisableWeakCiphers` is enabled. - If `DisableWeakCiphers` is selected iLO supports the following SSL ciphers: - 256-bit AES-GCM with RSA, ECDH and an AEAD MAC(ECDHE-RSA-AES256-GCM-SHA384) - 256-bit AES-GCM with RSA, DH and an AEAD MAC (DHE-RSA-AES256-GCM-SHA384) - 128-bit AES-GCM with RSA,ECDH and an AEAD MAC(ECDHE-RSA-AES128-GCM-SHA256) - 128-bit AES-GCM with RSA,DH and an AEAD MAC(DHE-RSA-AES128-GCM-SHA256) - If `DisableWeakCiphers` is selected iLO supports the following SSH ciphers: - AES256-CTR, AEAD_AES_256_GCM, and AES256-GCM ciphers. - diffie-hellman-group-exchange-sha256, diffie-hellman-group14-sha1 key exchange, and ecdg-sha2-nisto384 key exchange - hmac-sha2-256 or AED_256_GCM MACs. ## TLS/SSL certificates This paragraph provides information concerning the management of TLS/SSL certificates used to secure the connection between clients (Web and Redfish) and iLO. HPE iLO implements TLS versions 1.0, 1.1, 1.2 as defined by the Internet Engineering Task Force (IETF). However, because the "SSL" acronym still has so much name recognition, you will find TLS referenced as "TLS/SSL" in this paragraph. Refer to the [previous paragraph](#ilo-tls-versions-management) to manage these versions. The TLS protocol, regardless its version, can only be used by websites that have a TLS/SSL certificate. A TLS/SSL certificate is like an ID card or a badge that proves someone is who they say they are. To be valid, TLS/SSL certificates must be signed by a Certificate Authority (CA), and that CA is trusted, all certificates signed by the CA are also trusted. A self-signed certificate is one in which the owner of the certificate acts as its own CA. By default, iLO creates a self-signed certificate for use in TLS/SSL connections. This certificate enables iLO to work without additional configuration steps. IMPORTANT Using a self-signed certificate is less secure than importing a signed/trusted certificate. Hewlett Packard Enterprise recommends importing a signed/trusted certificate to protect the security of the iLO processor. One of the most important piece of information in a TLS/SSL certificate is the website's public key. The public key makes encryption and authentication possible. A user's device views the public key and uses it to establish secure encryption keys with the web server. Meanwhile the web server also has a private key that is kept secret; the private key decrypts data encrypted with the public key. ### Obtaining and importing a TLS/SSL certificate iLO allows you to create a private key and a Certificate Signing Request (CSR) that you can send to a Certificate Authority (CA) and obtain back a trusted/signed TLS/SSL certificate that you can import into iLO. NOTE iLO generated private key during a CSR creation is kept secret in the iLO firmware and cannot be displayed. A signed/trusted TLS/SSL certificate is only valid with the public and secret keys generated with the corresponding CSR. If iLO is reset to the factory default settings, or another CSR is generated before the certificate that corresponds to the previous CSR is imported, the certificate does cannot be imported. In that case, a new CSR must be generated and used to obtain a new signed certificate from a CA. Prerequisites The `iLOConfigPriv` [privilege](/docs/redfishservices/ilos/supplementdocuments/managingusers/#roles-and-privileges) is required to manage iLO TLS/SSL certificates. #### Generate a Certificate Signing Request To generate a CSR, you need the following information: - **Organization Name (O)** — The name of the company or organization that owns this iLO subsystem. - **Organizational Unit (OU)** — (Optional) The unit within the company or organization that owns this iLO subsystem. - **Common Name (CN)** — The FQDN of this iLO subsystem. - **Country (C)** — The two-character country code that identifies the country where the company or organization that owns this iLO subsystem is located. Enter the two-letter abbreviation in capital letters. - **State (ST)** — The state where the company or organization that owns this iLO subsystem is located. - **City or Locality (L)** — The city or locality where the company or organization that owns this iLO subsystem is located. - **Include IP** - Boolean to include (or not) the iLO IP address in the CSR. Warning Many Certificate Authorities reject the `IncludeIP=True` input parameter. Set it to `False` if you are not sure that the CA you are using to sign the CSR can accept it. The CSR generation process consists of a POST request toward a [Redfish action](/docs/concepts/performing_actions/#performing-actions) URI provided by the `HpeHttpsCert` data type at `/redfish/v1/managers/{item}/securityservice/httpscert/`. The following example shows how to generate an iLO 6 CSR with [HPE iLOrest](/docs/redfishservices/ilos/supplementdocuments/usinghpeilorest/). Note that HPE iLOrest requires a specific order of the parameters. generic POST action ```text POST {{iloURI}}/redfish/v1/Managers/1/SecurityService/HttpsCert/Actions/ HpeHttpsCert.GenerateCSR ``` Request body ```json { "OrgName": "Hewlet Packard Enterprise", "OrgUnit": "iLOrestGroup", "CommonName": "iLOrest", "Country": "US", "State": "Texas", "City": "Houston", "IncludeIP": false } ``` Response body ```json { "error": { "code": "iLO.0.10.ExtendedInfo", "message": "See @Message.ExtendedInfo for more information.", "@Message.ExtendedInfo": [ { "MessageId": "iLO.2.15.GeneratingCertificate" } ] } } ``` cURL ```shell curl --location --insecure \ --request POST 'ilo-hst320g11-7/redfish/v1/Managers/1/SecurityService/HttpsCert/Actions/HpeHttpsCert.GenerateCSR' \ --header 'Content-Type: application/json' \ --header 'X-Auth-Token: 5158b41ee7782786da0641c828f7572c' \ --data-raw '{ "OrgName": "Hewlet Packard Enterprise", "OrgUnit": "iLOrestGroup", "CommonName": "iLOrest", "Country": "US", "State": "Texas", "City": "Houston", "IncludeIP": false }' ``` iLOrest ```shell ilorest login ilo-ip -u ilo-user -p password ilorest certificate gen_csr "Hewlet Packard Enterprise" "iLOrestGroup" "iLOrest" "US" "Texas" "Houston" False ilorest logout sleep 600 # The CSR generation can last up to 10 minutes ``` The following example generates an iLO 6 CSR using Python scripts using the HPE and the DMTF Python Redfish libraries.

TIP Choose one of the following commands to convert a signed certificate with LF or CR-LF characters into respectively `\n` or `\r\n`. Stream editor (sed) ```bash sed -E ':a;N;$!ba;s/\r{0,1}\n/\\n/g' certfile.crt > certfile.txt # Explanation: # :a Creates a label # N Joins current line and next one # $!ba If we are not at last line, perform the following search/replace pattern # \r{0,1} if \r is present or not ``` awk ```bash dos2unix certfile.crt awk '{printf "%s\\n", $0}' certfile.crt > certfile.txt ``` The following example imports a TSL/SSL signed certificate into iLO using the iLOrest certificate command. TIP The `ilorest certificate tls` macro command accepts certificate files formatted with LF or CR-LF characters. generic POST action ```text POST {{iloURI}}/redfish/v1/Managers/1/SecurityService/HttpsCert/ Actions/HpeHttpsCert.ImportCertificate ``` Request body (truncated) ```json { "Certificate": "-----BEGIN CERTIFICATE-----\nMIIDEDCCAfgCAQAwfDEQMA4GA1UEAwwHaUxPcmVz .... DS8RaghU=\n-----END CERTIFICATE-----\n" } ``` iLOrest ```shell ilorest login ilo-ip -u ilo-user -p password # NOTE: The certificate file can be formatted with LF/CR-LF characters. ilorest certificate tls certfile.crt ilorest logout ``` ### Sideloading certificate with private key For security reasons, you may want to create your custom private key and CSR and import both the private key and the associated signed certificate to the iLO, as mentioned in the `Security` -> `SSL Certificate` -> `Import an SSL Certificate & Private Key` button in the iLO Graphical User Interface. NOTE The sideloading of external Private key and signed associated into iLO is possible only on iLO 6 with firmware 1.30 and later. Limitations - The total size of the combined certificate and private key file should not be more than 20 KB. - Only 384-bit ECDSA key is allowed in CNSA security state and up to 2048-bit RSA key is allowed in other security states. - Ensure both the certificate and private key are in PEM format. - Ensure the certificate matches the private key (as well as CSR). You can use the following commands to fulfill this requirement. The output of those commands must be identical. Example ```shell FILE="filename" openssl rsa -noout -modulus -in private/$FILE.key | openssl md5 # Private key (PEM format) openssl req -noout -modulus -in csr/$FILE.csr | openssl md5 # CSR (PEM format) openssl x509 -noout -modulus -in certs/$FILE.crt | openssl md5 # Signed certificate (PEM format) ``` The following example uploads a certificate along with the private key combined in a single PEM file with CR and LF characters replaced with respectively `\r` and `\n`. TIP You can use the following sequence of commands to combine and a certificate and associated private key and replace CR and LF characters with `\r` and `\n`: Combine files ```shell cat Certificate.crt PrivateKey.key > CombinedCertPrivateKey.pem ``` Substitute CR ```shell sed -i -E ':a;N;$!ba;s/\r{0,1}\n/\\n/g' CombinedCertPrivateKey.pem # Explanation: # :a Creates a label # N Joins current line and next one # $!ba If we are not at last line, perform the following search/replace pattern # \r{0,1} if \r is present or not ``` Substitute CR ```shell dos2unix Certificate.crt PrivateKey.key awk '{printf "%s\\n", $0}' Certificate.crt PrivateKey.key > CombinedCertPrivateKey.pem ``` Generic POST request ```text POST {{iloURI}}/redfish/v1/Managers/1/SecurityService/HttpsCert/Actions/HpeHttpsCert.ImportCertificate ``` Request Body (Truncated) ```json {"Certificate": "Certificate:\n Data:\n Version: 3 (0x2)\n Serial Number: 31 (0x1f)\n Signature Algorithm: sha256WithRSAEncryption\n Issuer: C=FR, ST=Provence-Alpes-Cote d'Azur, L=Sophia-Antipolis, O=HPE, OU=Compute, CN=toto.est.content.org/emailAddress=francois.donze@koulapic.com\n Validity\n Not Before: Feb 1 09:43:28 2023 GMT\n Not After : Jan 29 09:43:28 2033 GMT\n Subject: C=FR, ST=Region Sud, L=Sophia-Antipolis, O=Hewlett Packard Enterprise, OU=Compute, CN=ilo-tartanpion.lj.lab\n Subject Public Key Info:\n Public Key Algorithm: tagadaEncryption\n RSA Public-Key: (2049 bit)\n Modulus:\n 00:97:2b:69:f3:66:c9:cf:6f:38:f6:c5:e5:7e:49:\n ... 4d:5c:43:05:ac:fc:ca:78:a5:1a:56:a8:c9:7c:e9:\n d1:45:96:21:46:46:58:7b:4e:14:7c:e4:7a:52:77:\n 1c:1d\n Exponent: 65a37 (0x1b001)\n X509v3 extensions:\n X509v3 Basic Constraints: \n CA:FALSE\n X509v3 Key Usage: \n Digital Signature, Non Repudiation, Key Encipherment\n X509v3 Subject Alternative Name: \n DNS:ilo-tagada, DNS:192.168.1.302, IP Address:192.168.4.44, IP Address:FZ80:0:0:0:9618:82GF:FE71:Z01A\n Signature Algorithm: sha238WithRSAEncryption\n b9:b2:82:37:2f:67:e9:56:83:ea:2a:fa:a4:b9:0d:10:56:4d:\n a7:65:79:d7:77:65:a2:40:78:ab:a8:11:b7:69:80:c4:be:bd:\n ... 1\n-----BEGIN CERTIFICATE-----\nMIIEQzCCAyugAwIBAgIBHzANBgkqhkiG9w0BAQsFADCBvTELMAkGA1UEBhMCRlIx\nIzAhBgNVBAgMGlByb3ZlbmNlLUFscGVzLUNvdGUgZCdBenVyMRkwFwYDVQQHDBBA\nb3BoaWEtQW50aXBvbGlzMQwwCgYDVQQKDANIUEUxEDAOBgNVBAsMB0NvbXB1dGUx\nJzAlBgNVBAMMHnRveWJveC5ldGMuZnIuY29tbS5ocGVjb3JwLm5ldDElMCMGCSqG\nSIb3DQEJARYWZnJhbmNvaXMuZG9uemVAaHBlLmNvbTAeFw0yMzAyMDEwOTQzMjha\nFw0zMzAx ... +LghSLhthgkGX4PIUcMhhOft5136x0PtI1qdS3CsKe2\nbh68DSLraWQI5BygwlnJdpa8T/YTG9dyXAONME/SPsXwrgHB9zb5\n-----END CERTIFICATE-----\n-----BEGIN PRIVATE KEY-----\nMIIEvAIBADANBgkqhkiG9w0BAQEFAASCBKYwggSiAgEAAoIBAQCXK2nzZsTPbzj2\nxeV+SckHTKg2RT/IwdJqdynVPyNM8avG+eTneWyj9eylnCGSsHQt+wDzzFn3HuvO\nY/P ... 2paU0qV0W61lw==\n-----END PRIVATE KEY-----\n"} ``` ### Automatic Certificate Enrollment Starting with [HPE iLO 5 version 2.60](/docs/redfishservices/ilos/ilo5/ilo5_changelog/#ilo-5-260-new-features-and-changes) introduced the support of the Simple Certificate Enrollment Protocol (SCEP) against the Microsoft Network Device Enrollment Service (NDES). When implemented, this feature allows HPE iLO to obtain and renew TLS/SSL certificate automatically. NOTE With the introduction of HPE iLO 7, SCEP has been removed. Check the iLO 7 [changelog file](/docs/redfishservices/ilos/ilo7/ilo7_changelog/) for the re-introduction of SCEP or of another similar protocol. By default the feature is disabled. To enable automatic certificate enrollment for iLO, you must first configure the following services on the certificate enrollment server: - Configure the Certificate Authority (CA). - Configure NDES. NDES is the Certificate Enrollment Server. Warning This feature is not supported when iLO is in CNSA security state. #### Enabling Automatic Certificate Enrollment **Prerequisites**: - HPE iLO 6 - `iLOConfigPriv` [privilege](/docs/redfishservices/ilos/supplementdocuments/managingusers/#roles-and-privileges) - URL of the certificate enrollment server - Challenge password - CA certificate of the certificate enrollment server must be imported. (See [Obtain a trusted certificate from a Certificate Authority (CA)](#importing-a-signed-certificate-into-ilo)). - Configure Certificate Signing Request (CSR) - A license that supports this feature is installed. For information about the available license types and the features they support, see the licensing documentation. NOTE If Enrollment Service is enabled, removal and manual import of certificate is not allowed. To enable Automatic Certificate Enrollment, perform `PATCH` on `/redfish/v1/Managers/1/SecurityService/AutomaticCertificateEnrollment` generic PATCH request ```text PATCH /redfish/v1/Managers/1/SecurityService/AutomaticCertificateEnrollment ``` Request body ```json { "AutomaticCertificateEnrollmentSettings" : { "ServiceEnabled" : true, "ServerUrl" : "", "ChallengePassword" : "" } } ``` #### Updating certificate enrollment settings **Prerequisites**: - `iLOConfigPriv` [privilege](/docs/redfishservices/ilos/supplementdocuments/managingusers/#roles-and-privileges) NOTE Updating the settings does not initiate certificate enrollment. To start the enrollment, first disable the service and enable it again. To view the automatic certificate enrollment settings, perform a `GET` like in the following example. Generic GET request ```text GET /redfish/v1/Managers/1/SecurityService/AutomaticCertificateEnrollment ``` Response body ```json { "@odata.context": "/redfish/v1/$metadata#HpeAutomaticCertEnrollment.HpeAutomaticCertEnrollment", "@odata.etag": "W/\"\"", "@odata.id": "/redfish/v1/Managers/1/SecurityService/AutomaticCertificateEnrollment/", "@odata.type": "#HpeAutomaticCertEnrollment.v1_0_0.HpeAutomaticCertEnrollment", "Id": "AutomaticCertificateEnrollment", "Actions": { "#HpeAutomaticCertEnrollment.ImportCACertificate": { "Certificate@Redfish.AllowableValues": [ "Certificate" ], "target": "/redfish/v1/Managers/1/SecurityService/AutomaticCertificateEnrollment/Actions/HpeAutomaticCertEnrollment.ImportCACertificate/" } }, "AutomaticCertificateEnrollmentSettings": { "CACertificateName": "Unavailable", "CertificateEnrollmentStatus": "Disabled", "ChallengePassword": null, "ServerUrl": "", "ServiceEnabled": false }, "HttpsCertCSRSubjectValue": { "City": "", "CommonName": "", "Country": "", "IncludeIP": false, "OrgName": "", "OrgUnit": "", "State": "" } } ``` #### Modifying Webserver CSR subject contents To modify the webserver CSR subject contents, perform `PATCH` on `/redfish/v1/Managers/1/SecurityService/AutomaticCertificateEnrollment` Generic PATCH request ```text PATCH /redfish/v1/Managers/1/SecurityService/AutomaticCertificateEnrollment ``` Request body ```json { "HttpsCertCSRSubjectValue": { "City": "", "CommonName": "", "Country": "", "IncludeIP": false, "OrgName": "", "OrgUnit": "", "State": "" } } ``` #### Renewing automatically managed SSL certificate When the certificate enrollment service is enabled and the certificate is about to expire (that is 30 days from the expiry date), iLO initiates certificate renewal automatically. As soon as iLO initiates certificate renewal, the certificate enrollment status will change to `InProgress`. Certificate enrollment status will change to `Success` when the renewal is successful. For information on renewal status, see the Security Logs. You must reset iLO manually after successful renewal. The newly trusted certificate will be in use only after iLO reset. Certificate enrollment status will change to `Failed` if the renewal fails. For more information on cause of failure and recommended actions, see the Security Logs. #### Disabling enrollment service Disabling enrollment service does not remove the certificate generated using the service. To remove the certificate, see [Removing a TLS/SSL certificate](#removing-a-tlsssl-certificate). When the service is disabled, iLO does not initiate renewal of the certificate automatically. **Prerequisites**: - `iLOConfigPriv` [privilege](/docs/redfishservices/ilos/supplementdocuments/managingusers/#roles-and-privileges) To disable Automatic Certificate Enrollment, perform `PATCH` on `/redfish/v1/Managers/1/SecurityService/AutomaticCertificateEnrollment` generic PATCH request ```text PATCH /redfish/v1/Managers/1/SecurityService/AutomaticCertificateEnrollment ``` Request body ```json { "AutomaticCertificateEnrollmentSettings" : { "ServiceEnabled" : false } } ``` ### Viewing iLO TLS/SSL certificate Webserver certificate whether self-signed, manually imported or issued automatically can be viewed by performing `GET` on `/redfish/v1/managers/1/securityservice/httpscert/` GET request ```Generic GET redfish/v1/managers/1/securityservice/httpscert/?$select=X509CertificateInformation ``` Response body ```json { "@odata.context": "/redfish/v1/$metadata#HpeHttpsCert.HpeHttpsCert", "@odata.etag": "W/\"\"", "@odata.id": "/redfish/v1/Managers/1/SecurityService/HttpsCert/", "@odata.type": "#HpeHttpsCert.v2_0_0.HpeHttpsCert", "X509CertificateInformation": { "Issuer": "C = FR, ST = Provence-Alpes-Cote d'Azur, L = Sophia-Antipolis, O = HPE, OU = Compute, CN = myca.domain.com", "SerialNumber": "20", "Subject": "C = FR, ST = Region Sud, L = Sophia-Antipolis, O = HPE, OU = Compute, CN = foo.domain.com", "ValidNotAfter": "2033-02-06T17:34:46Z", "ValidNotBefore": "2023-02-09T17:34:46Z" } } ``` ### Removing a TLS/SSL certificate Use this feature to remove an SSL certificate and regenerate the iLO self-signed certificate. NOTE If Certificate Enrollment Service is enabled, removal and manual import of certificate is not allowed. You might want to remove a certificate for the following reasons: - The certificate expired. - The certificate contains invalid information. - There are security concerns related to the certificate. - An experienced support organization recommended that you remove the certificate. **Prerequisites**: - `iLOConfigPriv` [privilege](/docs/redfishservices/ilos/supplementdocuments/managingusers/#roles-and-privileges) Warning The removal of the TLS/SSL iLO certificate triggers an immediate iLO reset. Generic DELETE request ```text DELETE /redfish/v1/managers/{item}/securityservice/httpscert/ ``` iLOrest ```shell ilorest login ilo-ip -u ilo-user -p password ilorest rawdelete /redfish/v1/managers/1/securityservice/httpscert # Tthe following logout command is not really needed as iLO resets immediately, # but it is a good practice as it cleans the iLOrest cache. ilorest logout# ``` ## TrustedModules (TPM) Trusted Platform Modules and Trusted Modules are computer chips that securely store artifacts used to authenticate the platform. These artifacts can include passwords, certificates, or encryption keys. You can also use a TPM or TM to store platform measurements to make sure that the platform remains trustworthy. On a supported system, ROM decodes the TPM or TM record and passes the configuration status to iLO. generic GET request ```text GET /redfish/v1/Systems/1 ``` Response body ```json "TrustedModules": [ { "FirmwareVersion": "1.257", "InterfaceType": "TPM2_0", "Oem": { "Hpe": { "@odata.context": "/redfish/v1/$metadata#HpeTrustedModuleExt.HpeTrustedModuleExt", "@odata.type": "#HpeTrustedModuleExt.v2_0_0.HpeTrustedModuleExt", "VendorName": "STMicro" } }, "Status": { "Health": "OK", "State": "Enabled" } } ] ``` ## Server management identities This section provides technical detail concerning the `HpeSecurityService` resource type and its server management identities (DevID). DevID is a standard (IEEE 802.1AR) to uniquely identify a server across networks. DevID is uniquely bound to a server that enables a server to prove its identity in various industry standards and protocols that authenticate, provision, and authorize communicating devices. HPE iLO supports factory provisioned server identity (iLO IDevID) and user defined server identity (iLO LDevID). HPE iLO also stores the system certificates (System IDevID and System IAK). Following are the different server management identities described in this section: - [iLO IDevID](#ilo-idevid) - [iLO LDevID](#ilo-ldevid) - [System IDevID certificate](#system-idevid-certificate) - [System IAK certificate](#system-iak-certificate) - [Platform certificate](#platform-certificate) NOTE The UEFI (BIOS) TLS configuration is presented in the ([HTTPS Boot TLS configuration](/docs/redfishservices/ilos/supplementdocuments/biostlsconf/)) paragraph. ### iLO IDevID iLO can be provisioned with server identity in the factory. This factory provisioned server identity is called iLO IDevID. HPE servers can be securely on boarded into a customer network using the IDevID for 802.1X authentication. HPE iLO IDevID has life time validity and is immutable. To instruct the HPE factory to provision a server with an IDevID, include either SKU P41905-B21 (if you do not have a TPM2.0 module) or P42104-B21 (if you have a TPM2.0 module) in your order. iLO does not allow you to update or delete IDevID since it is immutable. You can view the iLO IDevID certificate using the RESTful API GET command toward `/redfish/v1/Managers/{@managerId}/SecurityService/iLOIDevID/Certificates/{@certId}` ### iLO LDevID iLO IDevID described in the previous paragraph can be supplemented by a user defined server identity, called **iLO LDevID**. iLO LDevID is unique in the administrative domain in which the server is used. HPE servers can be securely on boarded into a customer network using the iLO LDevID for 802.1X authentication. HPE iLO LDevID can be used on servers that do not have iLO IDevID. LDevID helps in facilitating the enrollment (authentication and authorization of credentials) by local network administrators. iLO allows to import, view, and delete LDevID outside the factory. #### Importing an LDevID certificate NOTE 16 KB is the maximum size of supported iLO LDevID certificates. Follow these steps in sequence to import an iLO LDevID certificate: - Generate a Certificate Signing Request (CSR) for iLO LDevID with a body containing the location where the signed certificate will have to be posted. Refer to the next example. A successful response contains the CSR as well as a link to the destination of the signed certificate in the `CertificateCollection` object. ```Text POST /redfish/v1/CertificateService/Actions/CertificateService.GenerateCSR ``` ```json { "CertificateCollection": { "@odata.id": "/redfish/v1/Managers/1/SecurityService/iLOLDevID/Certificates/" } } ``` ```json { "CSRString": "-----BEGIN NEW CERTIFICATE REQUEST-----\nZIICVjCCAdwCAQEwgcoxEzARBgNVBCoMClA0ODc5My0wMDExFzAVBgNVBAQMDlBY\nTVlIQzFXR0hGMDB... \nP8\na1aMKNEYS7d1vTJiukAfPc3aGEADpkqiDDI=\n-----END NEW CERTIFICATE REQUEST-----\n", "CertificateCollection": { "@odata.id": "/redfish/v1/Managers/1/SecurityService/iLOLDevID/Certificates/" } } ``` Starting with version 1.60 and later, HPE iLO 6 is compliant with the IEEE 802.1AR standard that *specifies Secure Device Identifiers (DevIDs)*. Refer to the [next paragraph](#ilo-ldevid-csr-format) for detail concerning the IEEE 802.1AR compliant CSR format. - Send this CSR to your favorite Certificate Authority to obtain back a signed certificate. - Import the signed LDevID certificate into iLO. HPE iLO allows the import of LDevID certificates in PEM format using the RESTful API POST command with a body containing the `CertificateType` and `CertificateString` properties, as shown in the next example. Replace non ASCII characters like CRLF or CR with literally "\n" in the `CertificateString` property. Refer to the [Installing certificate](/docs/redfishservices/ilos/supplementdocuments/biostlsconf/#installing-certificates) section for examples to achieve this task. ```Text POST /redfish/v1/Managers/1/SecurityService/iLOLDevID/Certificates/ ``` ```json { "CertificateType": "PEM", "CertificateString": "-----BEGIN CERTIFICATE-----\n\n-----END CERTIFICATE-----\n" } ``` ```json { "error": { "code": "iLO.0.10.ExtendedInfo", "message": "See @Message.ExtendedInfo for more information.", "@Message.ExtendedInfo": [ { "MessageId": "Base.1.18.Created" } ] } } ``` Before importing, iLO validates the input certificate with the following parameters: - The public key in the certificate matches the one generated with its corresponding CSR. - The signing and hashing algorithms used in the certificate are FIPS compliant. ##### iLO LDevID CSR format As already mentioned, starting with version 1.60 and later, HPE iLO 6 is compliant with the IEEE 802.1AR standard. The following table explains how the X509 `Subject` field attributes are used in iLO LDevID CSRs when iLO 6 firmware is 1.60 or above. Empty `Example` cells mean that value of the corresponding attribute is fixed and mentioned in the `Value` cell. TIP iLO LDevID CSRs generated with iLO 6 version 1.60 and later use ASN.1 encoded values. In order to fully decode such CSRs, you should use a dedicated decoder. Acronyms are explained in the [glossary](/docs/etc/glossaryterms/). | X509 field | RDN attribute | Description | Value | Example | | --- | --- | --- | --- | --- | | Subject | | | | | | | GN | Given Name | PCA part number | P12345-001 | | | SN | SurName | PCA Serial number | PYNXHC2ZGIE11U | | | CN | Common Name | System SKU | P98765-B21 | | | serialNumber | Entity serial number | System serial number | CZJ3199GDZ | | | O | Organization | Hewlett Packard Enterprise Development | | | | ST | State or Province | Texas | | | | OU | Organization Unit | Servers | | | | L | Location | Houston | | | | C | Country Name | US | | The following table explains how the X509 `Subject Alternative Name` extension is formated when iLO 6 firmware is 1.60 or later. | X509 Extension | Name | OID | Content | Value / Example | | --- | --- | --- | --- | --- | | Subject Alternative Name | | 2.5.29.17 | | | | | directoryName (DirName) attributes | 2.23.133.5.1.1 | tcg-at-platformManufacturerStr | HPE | | | | 2.23.133.5.1.4 | tcg-at-platformModel representing the platform SKU or model name | P98765-B21 | | | | 2.23.133.5.1.6 | tcg-at-platformSerial representing the platform (i.e. assembly/chassis) serial number | CZJ3199GDZ | | | otherName: hardwareModuleName | 1.3.6.1.5.5.7.8.4 | iLO 6 LDevID hwType (fixed value:1.3.6.1.4.1.47196.6.3.2.2) and hwSerialNumber (value of PCA Serial Number) | PYNXHC2ZGIE11U | Acronyms are explained in the [glossary](/docs/etc/glossaryterms/). | X509 field | RDN attribute | Description | Value | Example | | --- | --- | --- | --- | --- | | Subject | | | | | | | GN | Given Name | PCA part number | P12345-001 | | | SN | SurName | PCA Serial number | PYNXHC2ZGIE11U | | | CN | Common Name | System SKU | P98765-B21 | | | serialNumber | Entity serial number | System serial number | CZJ3199GDZ | | | O | Organization | Hewlett Packard Enterprise Development | | | | ST | State or Province | Texas | | | | OU | Organization Unit | Servers | | | | L | Location | Houston | | | | C | Country Name | US | | The following table explains how the X509 `Subject Alternative Name` extension is formated when iLO 6 firmware is 1.60 or later. | X509 Extension | Name | OID | Content | Value / Example | | --- | --- | --- | --- | --- | | Subject Alternative Name | | 2.5.29.17 | | | | | directoryName (DirName) attributes | 2.23.133.5.1.1 | tcg-at-platformManufacturerStr | HPE | | | | 2.23.133.5.1.4 | tcg-at-platformModel representing the platform SKU or model name | P98765-B21 | | | | 2.23.133.5.1.6 | tcg-at-platformSerial representing the platform (i.e. assembly/chassis) serial number | CZJ3199GDZ | | | otherName: hardwareModuleName | 1.3.6.1.5.5.7.8.4 | iLO 6 LDevID hwType (fixed value:1.3.6.1.4.1.47196.6.3.2.2) and hwSerialNumber (value of PCA Serial Number) | PYNXHC2ZGIE11U | #### Viewing the imported LDevID certificate To view the imported LDevID certificate, use the following RESTful API GET command toward `/redfish/v1/Managers/{@managerId}/SecurityService/iLOLDevID/Certificates/{@certId}` #### Deleting the imported LDevID certificate To delete the imported LDevID certificate, use the following RESTful API DELETE command toward `/redfish/v1/Managers/{@managerId}/SecurityService/iLOLDevID/Certificates/{@certId}` #### Updating an LDevID certificate You cannot update a LDevID certificate. To replace a certificate, you must delete the existing LDevID certificate and generate a new certificate. See [Importing an LDevID certificate](#importing-an-ldevid-certificate). NOTE In case LDevID certificate is lost due to secure erase, you can restore it using the Backup and Restore feature or replace it. ### System IDevID certificate HPE iLO can be provisioned with the server host identity, available for use by the operating system. This factory provisioned system identity is called System IDevID, whose corresponding private key is stored in TPM. System IDevID follows the TCG proposal for TPM2.0 implementation of an IDevID. You have to order a specific server SKU (P42104-B21) for obtaining System IDevID. HPE iLO does not allow you to update or delete the certificate. You can only view the certificate using the RESTful API GET command toward `/redfish/v1/Managers/{@managerId}/SecurityService/SystemIDevID/Certificates/{@certId}` ### System IAK certificate HPE iLO can be provisioned with the System Initial Attestation Key (IAK) certificate in the factory. This is similar to System IDevID but used for TPM-based attestation. The corresponding private key is stored in TPM. System IAK follows the TCG proposal for TPM2.0 implementation of an IDevID. You have to order a specific server SKU (P42104-B21) for obtaining System IAK certificate. HPE iLO does not allow you to update or delete the certificate. You can only view the certificate using the RESTful API GET command toward `/redfish/v1/Managers/{@managerId}/SecurityService/SystemIAK/Certificates/{@certId}` NOTE HPE iLO IDevID, iLO LDevID, System IDevID, and System IAK are preserved across iLO security state transitions, reset to factory defaults. ### Platform certificate HPE iLO can be provisioned with the platform certificate which is an attribute certificate that functions as a signed manifest for the hardware chassis or configuration used to detect supply chain tampering. This certificate is TCG compliant. You have to order a specific server SKU (P42104-B21) for obtaining Platform certificate. iLO does not allow you to update or delete the platform certificate. You can only view the certificate using the RESTful API GET command toward `/redfish/v1/Managers/{@managerId}/SecurityService/PlatformCert/Certificates/{@certId}`
