RHEL 9 must use a separate file system for the system audit data path.

STIG ID: RHEL-09-231030  |  SRG: SRG-OS-000341-GPOS-00132 |  Severity: low |  CCI: CCI-000366,CCI-001849 |  Vulnerability Id: V-257847 | 

Vulnerability Discussion

Placing "/var/log/audit" in its own partition enables better separation between audit files and other system files, and helps ensure that auditing cannot be halted due to the partition running out of space.

Satisfies: SRG-OS-000341-GPOS-00132, SRG-OS-000480-GPOS-00227

Check

Verify that a separate file system/partition has been created for the system audit data path with the following command:

Note: /var/log/audit is used as the example as it is a common location.

$ mount | grep /var/log/audit

UUID=2efb2979-45ac-82d7-0ae632d11f51 on /var/log/home type xfs (rw,realtime,seclabel,attr2,inode64)

If no line is returned, this is a finding.

Fix

Migrate the system audit data path onto a separate file system.
