Features such as Credential Guard use virtualization-based security to protect information that could be used in credential theft attacks if compromised. There are a number of system requirements that must be met in order for Credential Guard to be configured and enabled properly. Virtualization-based security and Credential Guard are only available with Windows 11 Enterprise 64-bit version.

If data at rest is unencrypted, it is vulnerable to disclosure. Even if the operating system enforces permissions on data access, an adversary can remove non-volatile memory and read it directly, thereby circumventing operating system controls. Encrypting the data ensures that confidentiality is protected even when the operating system is not running.
Fix: F-56662r828860_fix

Enable full disk encryption on all information systems (including SIPRNet) using BitLocker. BitLocker, included in Windows, can be enabled in the Control Panel under "BitLocker Drive Encryption" as well as other management tools. Note: An alternate encryption application may be used in lieu of BitLocker providing it is configured for full disk encryption and satisfies the pre-boot authentication requirements (WN11-00-000031 and WN11-00-000032).

Windows 11 is maintained by Microsoft at servicing levels for specific periods of time to support Windows as a Service. Systems at unsupported servicing levels or releases will not receive security updates for new vulnerabilities which leaves them subject to exploitation. New versions with feature updates are planned to be released on a semi-annual basis with an estimated support timeframe of 18 to 30 months depending on the release. Support for previously released versions has been extended for Enterprise editions. A separate servicing branch intended for special purpose systems is the Long-Term Servicing Channel (LTSC, formerly Branch - LTSB) which will receive security updates for 10 years but excludes feature updates.
Fix: F-56666r828872_fix

Configure DEP to at least OptOut. Note: Suspend BitLocker before making changes to the DEP configuration. Open a command prompt (cmd.exe) or PowerShell with elevated privileges (Run as administrator). Enter "BCDEDIT /set {current} nx OptOut". (If using PowerShell "{current}" must be enclosed in quotes.) "AlwaysOn", a more restrictive selection, is also valid but does not allow applications that do not function properly to be opted out of DEP. Opted out exceptions can be configured in the "System Properties". Open "System" in Control Panel. Select "Advanced system settings". Click "Settings" in the "Performance" section.

Without the use of multifactor authentication, the ease of access to privileged and nonprivileged functions is greatly increased. All domain accounts must be enabled for multifactor authentication with the exception of local emergency accounts. Multifactor authentication requires using two or more factors to achieve authentication. Factors include: 1) Something a user knows (e.g., password/PIN); 2) Something a user has (e.g., cryptographic identification device, token); and 3) Something a user is (e.g., biometric). A privileged account is defined as an information system account with authorizations of a privileged user. Network access is defined as access to an information system by a user (or a process acting on behalf of a user) communicating through a network (e.g., local area network, wide area network, or the internet). Local access is defined as access to an organizational information system by a user (or process acting on behalf of a user) communicating through a direct connection without the use of a network. The DoD CAC with DoD-approved PKI is an example of multifactor authentication. Satisfies: SRG-OS-000106-GPOS-00053, SRG-OS-000107-GPOS-00054, SRG-OS-000108-GPOS-00055
