For releases before OneFS 9.3.0.0, after the STIG security profile is applied, the concern from an administration perspective is how to manage a PowerScale cluster without root access through SSH. OneFS 9.3.0.0 and later releases do not disable root access. Further magnifying this complexity are scenarios where a cluster has been active previously before the STIG security profile was applied. In these cases, the administration of the cluster had a greater dependence on root access through SSH. The admin user may be used for some actions. As a best practice, use Role Based Access Control (RBAC) to delegate roles to users and groups, and control administrative access. The admin user can add administrative privileges to other users or create custom roles. For more information about RBACs, see the Dell PowerScale OneFS: Authentication, Identity Management, and Authorization white paper and the CLI Administration Guide for the specified release at OneFS Info Hubs.
If the API is not used for cluster administration, we recommend that you set up a role that has ISI_PRIV_LOGIN_SSH and ISI_PRIV_HARDENING privileges. Both privileges are configured for the admin user. STIG requirements prohibit shared accounts using RBAC with per-user accounts. The minimum required privileges per account are recommended.
In OneFS 9.5.0.0 and later, group authenticators are not allowed on PowerScale clusters with the STIG security profile. Group authenticators are accounts used by multiple people. For example, a group authenticator could be the admin account.
After the STIG security profile is applied, the login banner is updated. When a node is accessed through SSH or the web interface, the following banner is displayed:
You are accessing a US Government (USG) Information System (IS) that is provided for USG-authorized use only.
By using this IS (which includes any device attached to this IS), you consent to the following conditions:
-The USG routinely intercepts and monitors communications on this IS for purposes including, but not limited to, penetration testing, COMSEC monitoring, network operations and defense, personnel misconduct (PM), law enforcement (LE), and counterintelligence (CI) investigations.
-At any time, the USG may inspect and seize data stored on this IS.
-Communications using, or data stored on, this IS are not private, are subject to routine monitoring, interception, and search, and may be disclosed or used for any USG-authorized purpose.
-This IS includes security measures (e.g., authentication and access controls) to protect USG interests--not for your personal benefit or privacy.
-Notwithstanding the above, using this IS does not constitute consent to PM, LE or CI investigative searching or monitoring of the content of privileged communications, or work product, related to personal representation or services by attorneys, psychotherapists, or clergy, and their assistants. Such communications and work product are private and confidential. See User Agreement for details.
If a banner is configured prior the applying the STIG security profile, the existing banner is appended with the preceding text.
