Credential Guard is a security feature in Windows that helps protect user credentials from being stolen or compromised by malware. It uses virtualization-based security to isolate and protect the Local Security Authority (LSA) process and any secrets it handles. By doing so, it provides an additional layer of defense against credential theft attacks.

In the Windows environment, Credential Guard is an essential tool for organizations and individuals to protect sensitive information and prevent unauthorized access to their systems. It helps mitigate the risk of pass-the-hash, pass-the-ticket, and other credential-based attacks that can lead to data breaches and system compromise.

Examples:

1. Enabling Credential Guard via Group Policy:

• Open the Group Policy Management Editor by running "gpedit.msc" in the Run dialog.


• Navigate to "Computer Configuration" > "Administrative Templates" > "System" > "Device Guard" > "Turn on Virtualization Based Security."


• Enable the policy and select "Enabled with UEFI lock" to ensure the system cannot be downgraded to a less secure state.


• Restart the computer for the changes to take effect.

2. Verifying Credential Guard status using PowerShell:

• Open PowerShell as an administrator.


• Run the command "Get-CredentialGuardStatus" to check if Credential Guard is enabled.


• If the output shows "IsEnabled : True," then Credential Guard is active.
