Fix Recommendation

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":

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

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

Check Contents

Verify the operating system generates audit records when successful/unsuccessful attempts to use the "chcon" command occur.

Check the file system rule in "/etc/audit/audit.rules" with the following command:

# grep -i /usr/bin/chcon /etc/audit/audit.rules

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

If the command does not return any output, this is a finding.
