Audit Successful and Unsuccessful Attempts to Change File Permissions (Security Objects)
The permissions on a file establish which users are permitted to access or modify it. An attacker may attempt to change the permissions on a file to prevent legitimate users from accessing it or to grant additional access to an account the attacker controls. Auditing successful and unsuccessful attempts to modify security objects such as file permissions mitigates this risk.
Parameter:
[yes/no]
Technical Mechanism:
In order to view the currently configured flags for the audit daemon, run the following command:
sudo grep ^flags /etc/security/audit_control
Changes to file permissions are logged by way of the 'fm' flag. If 'fm' is not listed in the result of the check, this is a finding.
