Rules and Groups employed by this XCCDF Profile

  • SRG-OS-000480-GPOS-00229

    Group
    Show

  • The Photon operating system must configure Secure Shell (SSH) to disable user environment processing.

    Enabling user environment processing may enable users to bypass access restrictions in some configurations and must therefore be disabled.
    Rule High Severity
    Show

  • SRG-OS-000480-GPOS-00227

    Group
    Show

  • The Photon operating system must create a home directory for all new local interactive user accounts.

    If local interactive users are not assigned a valid home directory, there is no place for the storage and control of files they should own.
    Rule Medium Severity
    Show

  • SRG-OS-000480-GPOS-00227

    Group
    Show

  • The Photon operating system must disable the debug-shell service.

    The debug-shell service is intended to diagnose systemd related boot issues with various systemctl commands. Once enabled and following a system reboot, the root shell will be available on tty9. Th...

  • SRG-OS-000480-GPOS-00227

    Group
    Show

  • The Photon operating system must configure Secure Shell (SSH) to disallow Generic Security Service Application Program Interface (GSSAPI) authentication.

    GSSAPI authentication is used to provide additional authentication mechanisms to applications. Allowing GSSAPI authentication through Secure Shell (SSH) exposes the system's GSSAPI to remote hosts,...

  • SRG-OS-000480-GPOS-00227

    Group
    Show

  • The Photon operating system must configure Secure Shell (SSH) to disable X11 forwarding.

    X11 is an older, insecure graphics forwarding protocol. It is not used by Photon and should be disabled as a general best practice to limit attack surface area and communication channels.
    Rule Medium Severity
    Show

  • SRG-OS-000480-GPOS-00227

    Group
    Show

  • The Photon operating system must configure Secure Shell (SSH) to perform strict mode checking of home directory configuration files.

    If other users have access to modify user-specific SSH configuration files, they may be able to log on to the system as another user.
    Rule Medium Severity
    Show

  • SRG-OS-000480-GPOS-00227

    Group
    Show

  • The Photon operating system must configure Secure Shell (SSH) to disallow Kerberos authentication.

    If Kerberos is enabled through SSH, sshd provides a means of access to the system's Kerberos implementation. Vulnerabilities in the system's Kerberos implementation may then be subject to exploitat...

    Show

  • SRG-OS-000480-GPOS-00227

    Group
    Show

  • The Photon operating system must configure Secure Shell (SSH) to disallow compression of the encrypted session stream.

    If compression is allowed in an SSH connection prior to authentication, vulnerabilities in the compression software could result in compromise of the system from an unauthenticated connection.
    Rule Medium Severity
    Show

  • SRG-OS-000480-GPOS-00227

    Group
    Show

  • The Photon operating system must configure Secure Shell (SSH) to display the last login immediately after authentication.

    Providing users with feedback on the last time they logged on via SSH facilitates user recognition and reporting of unauthorized account use.
    Rule Medium Severity
    Show

  • SRG-OS-000480-GPOS-00227

    Group
    Show

  • The Photon operating system must configure Secure Shell (SSH) to ignore user-specific trusted hosts lists.

    SSH trust relationships enable trivial lateral spread after a host compromise and therefore must be explicitly disabled. Individual users can have a local list of trusted remote machines, which mus...

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
