Rules and Groups employed by this XCCDF Profile

  • SRG-OS-000078-GPOS-00046

    Group
  • The Oracle Linux operating system must be configured so that passwords are a minimum of 15 characters in length.

    The shorter the password, the lower the number of possible combinations that need to be tested before the password is compromised. Password complexity, or strength, is a measure of the effectivene...
    Rule Medium Severity
  • SRG-OS-000480-GPOS-00227

    Group
  • The Oracle Linux operating system 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.
    Rule High Severity
  • SRG-OS-000106-GPOS-00053

    Group
  • The Oracle Linux operating system must be configured so that the SSH daemon does not allow authentication using an empty password.

    Configuring this setting for the SSH daemon provides additional assurance that remote logon via SSH will require a password, even in the event of misconfiguration elsewhere.
    Rule High Severity
  • SRG-OS-000118-GPOS-00060

    Group
  • The Oracle Linux operating system must disable account identifiers (individuals, groups, roles, and devices) if the password expires.

    Inactive identifiers pose a risk to systems and applications because attackers may exploit an inactive identifier and potentially obtain undetected access to the system. Owners of inactive accounts...
    Rule Medium Severity
  • SRG-OS-000021-GPOS-00005

    Group
  • The Oracle Linux operating system must be configured to lock accounts for a minimum of 15 minutes after three unsuccessful logon attempts within a 15-minute timeframe.

    By limiting the number of failed logon attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute-forcing, is reduced. Limits are imposed by locking the a...

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.
