11.3 Set Graphical Warning Banner (Not Scored)
Profile Applicability
Description
Ubuntu defaults to using lightdm for graphical login session management which provides no built in banner setting. The GNOME Display Manager and KDM are both available but must be manually installed.
Rationale
Warning messages inform users who are attempting to login to the system of their legal status regarding the system and must include the name of the organization that owns the system and any monitoring policies that are in place. Consult your organization's legal counsel for the appropriate wording for your specific organization.
Audit Procedure
Using Command Line
If the X Window system is in use ensure a warning banner consistent with your organizations policy is in place.
Expected Result
A warning banner consistent with organizational policy is displayed prior to graphical login.
Remediation
Using Command Line
Set a banner for the display manager in use consistent with your organizations policy. This process depends on the specific Display Manager and theme in use, consult your documentation for more details.
Default Value
No graphical warning banner is configured by default.
