2.1.4 Ensure rsync service is not enabled

Information

The rsyncd service can be used to synchronize files between systems over network links.

Rationale:

The rsyncd service presents a security risk as it uses unencrypted protocols for communication.

Solution

Run the following command to disable rsyncd :

# systemctl --now disable rsyncd

/etc is stateless on Container-Optimized OS. Therefore, the steps mentioned above needs to be performed after every boot.

Additional Information:

Additional methods of disabling a service exist. Consult your distribution documentation for appropriate methods.

On some distributions the rsync service is known as rsync, not rsyncd.
