    Group
    Show

  • All TOSS local interactive users must have a home directory assigned in the /etc/passwd file.

    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.

    Group
    Show

  • TOSS must disable the user list at logon for graphical user interfaces.

    Leaving the user list enabled is a security risk since it allows anyone with physical access to the system to enumerate known user accounts without authenticated access to the system.

    Group
    Show

  • TOSS must display the date and time of the last successful account logon upon an SSH logon.

    Providing users with feedback on when account accesses via SSH last occurred facilitates user recognition and reporting of unauthorized account use.

    Group
    Show

  • TOSS must not allow accounts configured with blank or null passwords.

    If an account has an empty password, anyone could log on and run commands with the privileges of that account. Accounts with empty passwords should never be used in operational environments.

    Group

  • TOSS must not have unnecessary accounts.

    Group
    Show

  • TOSS must define default permissions for all authenticated users in such a way that the user can only read and modify their own files.

    Setting the most restrictive default permissions ensures that when new accounts are created, they do not have unnecessary access.

  • All TOSS local interactive user home directories must have mode 0770 or less permissive.

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.
