RHEL-08-010100 - RHEL 8, for certificate-based authentication, must enforce authorized access to the corresponding private key.

Information

If an unauthorized user obtains access to a private key without a passcode, that user would have unauthorized access to any system where the associated public key has been installed.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Create a new private and public key pair that utilizes a passcode with the following command:

$ sudo ssh-keygen -p -f /path/to/file
