Record Events that Modify the System's Mandatory Access Controls in usr/share

Description

If the auditd daemon is configured to use the augenrules program to read audit rules during daemon startup (the default), add the following line to a file with suffix .rules in the directory /etc/audit/rules.d:

-w /usr/share/selinux/ -p wa -k MAC-policy

If the auditd daemon is configured to use the auditctl utility to read audit rules during daemon startup, add the following line to /etc/audit/audit.rules file:

-w /usr/share/selinux/ -p wa -k MAC-policy

Rationale

The system's mandatory access policy (SELinux) should not be arbitrarily changed by anything other than administrator action. All changes to MAC policy should be audited.
