4.1.3.35 Ensure audit of the chcon command

Information

The operating system must audit all uses of the chcon command.

Rationale:

Without generating audit records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.

Audit records can be generated from various components within the information system (e.g., module or policy filter).

Solution

Configure the operating system to generate audit records when successful/unsuccessful attempts to use the chcon command occur.
Add or update the following rule in /etc/audit/rules.d/audit.rules:
Example: vim /etc/audit/rules.d/audit.rules
Add, uncomment or update the following line:

-a always,exit -F path=/usr/bin/chcon -F auid>=1000 -F auid!=4294967295 -k privileged-priv_change

The audit daemon must be restarted for the changes to take effect.

# service auditd restart
