Description
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.
ℹ️ Check
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 If the contents of the key are displayed, this is a finding.
✔️ Fix
Create a new private and public key pair that uses a passcode with the following command: $ sudo ssh-keygen -n [passphrase]
