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 Procedure

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 

/dev/mapper/rootvg-varlogaudit on /var/log/audit type xfs (rw,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=32k,noquota)
Note: Options displayed for mount may differ.

If no line is returned, this is a finding.

Fix Action

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