| 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 being disconnected from the network or domain controllers being unavailable. Even though the credential cache is well-protected, if a system is attacked, an unauthorized individual may isolate the password to a domain user account using a password-cracking program and gain access to the domain. | ||||

Registry Path: \SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\
Value Name: CachedLogonsCount

This is the default configuration for this setting (10 logons to cache).
Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> Security Options >> "Interactive logon: Number of previous logons to cache (in case domain controller is not available)" to "10" logons or less.
This setting only applies to domain-joined systems, however, it is configured by default on all systems.
