Level 1 - Workstation

Systems need to have package manager repositories configured to ensure they receive the latest patches and updates.

If a system's package repositories are misconfigured important patches may not be identified or a rogue repository could introduce compromised software.

Run the following command and verify package repositories are configured correctly:

# apt-cache policy

Configure your package manager repositories according to site policy.
