The Information System Security Officer (ISSO) and System Administrator (SA), at a minimum, must have mail aliases to be notified of a SUSE operating system audit processing failure.

Description
It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without this notification, the security personnel may be unaware of an impending failure of the audit capability, and system operation may be adversely affected. Audit processing failures include software/hardware errors, failures in the audit capturing mechanisms, and audit storage capacity being reached or exceeded. This requirement applies to each audit data storage repository (i.e., distinct information system component where audit records are stored), the centralized audit storage capacity of organizations (i.e., all audit data storage repositories combined), or both.

Check Text ( C-76853r2_chk )
Verify the administrators are notified in the event of a SUSE operating system audit processing failure by checking that "/etc/aliases" has a defined value for root. # grep postmaster /etc/aliases postmaster: root If the above command does not return a value of "root", this is a finding.

Fix Text (F-83939r1_fix)
Configure the auditd service to notify the administrators in the event of a SUSE operating system audit processing failure. Configure "/etc/aliases" to define a value for root (if it does not already exist). Add the following line in "/etc/aliases": postmaster: root
