OL07-00-020029 - The Oracle Linux operating system must use a file integrity tool to verify correct operation of all security functions.

Information

Without verification of the security functions, security functions may not operate correctly, and the failure may go unnoticed. Security function is defined as the hardware, software, and/or firmware of the information system responsible for enforcing the system security policy and supporting the isolation of code and data on which the protection is based. Security functionality includes, but is not limited to, establishing system accounts, configuring access authorizations (i.e., permissions, privileges), setting events to be audited, and setting intrusion detection parameters.

This requirement applies to the Oracle Linux operating system performing security function verification/testing and/or systems and environments that require this functionality.

Solution

Install AIDE, initialize it, and perform a manual check.

Install AIDE:
$ sudo yum install aide

Initialize it:
$ sudo /usr/sbin/aide --init

AIDE, version 0.15.1
### AIDE database at /var/lib/aide/aide.db.new.gz initialized.

The new database will need to be renamed to be read by AIDE:
$ sudo mv /var/lib/aide/aide.db.new.gz /var/lib/aide/aide.db.gz

Perform a manual check:
$ sudo /usr/sbin/aide --check

AIDE, version 0.15.1
### All files match AIDE database. Looks okay!

Done.
