AI-suggested

European organizations should ensure that all Windows 10 systems, particularly those running Version 21H1 with Credential Guard enabled, are updated with the latest security patches from Microsoft as soon as they become available. In the absence of a direct patch, organizations should consider disabling Credential Guard temporarily if the risk of credential exposure outweighs the benefits, while monitoring for suspicious local activity. Implement strict access controls to limit local user privileges and reduce the number of users with local access to sensitive systems. Employ endpoint detection and response (EDR) solutions to monitor for unusual credential access patterns or attempts to bypass Credential Guard protections. Additionally, enforce multi-factor authentication (MFA) and network segmentation to limit the impact of any credential disclosure. Regularly audit and review local user accounts and privileges to minimize the attack surface. Finally, conduct user training to raise awareness about the risks of local privilege misuse and insider threats.
