Group -
The Oracle Linux operating system must be configured so that the file permissions, ownership, and group membership of system files and commands match the vendor values.
Discretionary access control is weakened if a user or group has access permissions to system files and directories greater than the default. Satisfies: SRG-OS-000257-GPOS-00098, SRG-OS-000278-GPOS...Rule High Severity -
The Oracle Linux operating system must be configured so that the cryptographic hash of system files and commands matches vendor values.
Without cryptographic integrity protections, system command and files can be altered by unauthorized users without detection. Cryptographic mechanisms used for protecting the integrity of informat...Rule High Severity -
The Oracle Linux operating system must display the Standard Mandatory DoD Notice and Consent Banner before granting local or remote access to the system via a graphical user logon.
The display of a standardized and approved use notification before granting access to the operating system ensures privacy and security notification verbiage used is consistent with applicable fede...Rule Medium Severity -
The Oracle Linux operating system must display the Standard Mandatory DoD Notice and Consent Banner before granting local or remote access to the system via a command line user logon.
Display of a standardized and approved use notification before granting access to the operating system ensures privacy and security notification verbiage used is consistent with applicable federal ...Rule Medium Severity -
The Oracle Linux operating system must uniquely identify and must authenticate users using multifactor authentication via a graphical user logon.
To assure accountability and prevent unauthenticated access, users must be identified and authenticated to prevent potential misuse and compromise of the system. Multifactor solutions that require...Rule Medium Severity -
The Oracle Linux operating system must initiate a session lock for the screensaver after a period of inactivity for graphical user interfaces.
A session time-out lock is a temporary action taken when a user stops work and moves away from the immediate physical vicinity of the information system but does not log out because of the temporar...Rule Medium Severity -
The Oracle Linux operating system must be configured so that when passwords are changed or new passwords are established, the new password must contain at least one upper-case character.
Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resistin...Rule Medium Severity -
The Oracle Linux operating system must be configured so that when passwords are changed a minimum of four character classes must be changed.
Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resistin...Rule Medium Severity -
The Oracle Linux operating system must be configured so that passwords for new users are restricted to a 24 hours/1 day minimum lifetime.
Enforcing a minimum password lifetime helps to prevent repeated password changes to defeat the password reuse or history enforcement requirement. If users are allowed to immediately and continually...Rule Medium Severity

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.
