Check Content

The Audit Configuration profile is required. This check applies to the global zone only. Determine the zone currently being secured. # zonename If the command output is "global", this check applies. Determine the OS version currently being secured. # uname -v For Solaris 11, 11.1, 11.2, and 11.3: # pfexec auditconfig -getflags | grep active | cut -f2 -d= If "ps" audit flag is not included in the output, this is a finding. For Solaris 11.4 or newer: # pfexec auditconfig -t -getflags | cut -f2 -d= If "cusa,fm,fd,-fa,-ps,-ex" audit flags are not included in the 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 currently being secured. # 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.
