Title

The audit system must be configured to audit the loading and unloading of dynamic kernel modules. (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. 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 "as" 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.
