Title

The audit system must be configured to audit all discretionary access control permission modifications. (Cat II impact)

Discussion

Without auditing, individual system accesses cannot be tracked, and malicious activity cannot be detected and traced back to an individual account.

Check Content

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.

Fix Text

The Audit Configuration profile is required. All audit flags must be enabled in a single command. This action applies to the global zone only. Determine the zone that you are currently securing. # zonename If the command output is "global", this action applies. For Solaris 11, 11.1, 11.2, and 11.3: # pfexec auditconfig -setflags cusa,-ps,fd,-fa,fm For Solaris 11.4 or newer: # pfexec auditconfig -setflags cusa,-fa,-ex,-ps,fd,fm Enable the audit policy to collect command line arguments. # pfexec auditconfig -setpolicy +argv These changes will not affect users that are currently logged in.
