Description
The default Windows configuration caches the last logon credentials for users who log on interactively to a system. This feature is provided for system availability reasons such as the user’s machine is disconnected from the network or domain controllers are not available. Even though the credential cache is well-protected, storing encrypted copies of users passwords on systems do not always have the same physical protection required for domain controllers. If a system is attacked, the unauthorized individual may isolate the password to a domain user account using a password-cracking program, and gain access to the domain.
