Check Text ( C-21673r370886_chk )

The Audit Configuration profile is required.

Check that the audit flag for auditing file access is enabled.

This check applies to the global zone only. Determine the zone that you are currently securing.

# zonename

If the command output is "global", this check applies.

Determine the OS version you are currently securing.
# uname –v

For Solaris 11, 11.1, 11.2, and 11.3:
# pfexec auditconfig -getflags | grep active | cut -f2 -d=
If "fm" audit flag is not included in output, this is a finding.

For Solaris 11.4 or newer:
# pfexec auditconfig -t -getflags | cut -f2 -d=

If "fm" audit flag is not included in output, this is a finding.

Determine if auditing policy is set to collect command line arguments.

# pfexec auditconfig -getpolicy | grep active | grep argv

If the active audit policies line does not appear, this is a finding.
