Discussion

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.

Check Content

Verify the SSH private key files have a passcode.

For each private key stored on the system, use the following command:

$ sudo ssh-keygen -y -f /path/to/file
Enter passphrase:

If the contents of the key are displayed, this is a finding.

Fix Text

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

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