Inappropriate granting of user rights can provide system, administrative, and other high level capabilities. Accounts with the "Act as part of the operating system" user right can assume the identity of any user and gain access to resources that user is authorized to access. Any accounts with this right can...
V-220938 High The LanMan authentication level must be set to send NTLMv2 response only, and to refuse LM and NTLM. The Kerberos v5 authentication protocol is the default for authentication of users who are logging on to domain accounts. NTLM, which is less secure, is retained in later Windows versions for compatibility with clients and servers that are running earlier versions of Windows or applications that still use it. It...
V-220937 High The system must be configured to prevent the storage of the LAN Manager hash of passwords. The LAN Manager hash uses a weak encryption algorithm and there are several tools available that use this hash to retrieve account passwords. This setting controls whether or not a LAN Manager hash of the password is stored in the SAM the next time the password is changed.
V-220932 High Anonymous access to Named Pipes and Shares must be restricted. Allowing anonymous access to named pipes or shares provides the potential for unauthorized system access. This setting restricts access to those defined in "Network access: Named Pipes that can be accessed anonymously" and "Network access: Shares that can be accessed anonymously", both of which must be blank under other requirements.
V-220930 High Anonymous enumeration of shares must be restricted. Allowing anonymous logon users (null session connections) to list all account names and enumerate all shared resources can provide a map of potential points to attack the system.
V-220929 High Anonymous enumeration of SAM accounts must not be allowed. Anonymous enumeration of SAM accounts allows anonymous log on users (null session connections) to list all accounts names, thus providing a list of potential points to attack the system.
V-220928 High Anonymous SID/Name translation must not be allowed. Allowing anonymous SID/Name translation can provide sensitive information for accessing a system. Only authorized users must be able to perform such translations.
V-220865 High The Windows Remote Management (WinRM) service must not use Basic authentication. Basic authentication uses plain text passwords that could be used to compromise a system.

Virtualization-based security and Credential Guard are only available with Windows 10 Enterprise...
V-252903 Low Virtualization-based protection of code integrity must be enabled. Virtualization-based protection of code integrity enforces kernel mode memory protections and protects Code Integrity validation paths. This isolates the processes from the rest of the operating system and can only be accessed by privileged system software.
V-220954 Low Toast notifications to the lock screen must be turned off. Toast notifications that are displayed on the lock screen could display sensitive information to unauthorized personnel. Turning off this feature will limit access to the information to a logged on user.
V-220943 Low The default permissions of global system objects must be increased. Windows systems maintain a global list of shared system resources such as DOS device names, mutexes, and semaphores. Each type of object is created with a default DACL that specifies who can access the objects with what permissions. If this policy is enabled, the default DACL is stronger, allowing non-admin...
V-220923 Low Caching of logon credentials must be limited. 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...
V-220922 Low The Windows dialog box title for the legal banner must be configured. Failure to display the logon banner prior to a logon attempt will negate legal proceedings resulting from unauthorized access to system resources.
V-220918 Low The maximum age for machine account passwords must be configured to 30 days or less. Computer account passwords are changed automatically on a regular basis. This setting controls the maximum password age that a machine account may have. This setting must be set to no more than 30 days, ensuring the machine changes its password monthly.
V-220917 Low The computer account password must not be prevented from being reset. Computer account passwords are changed automatically on a regular basis. Disabling automatic password changes can make the system more vulnerable to malicious access. Frequent password changes can be a significant safeguard for your system. A new password for the computer account will be generated every 30 days.
V-220872 Low Windows 10 should be configured to prevent users from receiving suggestions for third-party or additional applications. Windows spotlight features may suggest apps and content from third-party software publishers in addition to Microsoft apps and content.
V-220838 Low Turning off File Explorer heap termination on corruption must be disabled. Legacy plug-in applications may continue to function when a File Explorer session has become corrupt. Disabling this feature will prevent this.
V-220835 Low Windows Update must not obtain updates from other PCs on the internet. Windows 10 allows Windows Update to obtain updates from additional sources instead of Microsoft. In addition to Microsoft, updates can be obtained from and sent to PCs on the local network as well as on the internet. This is part of the Windows Update trusted process; however, to minimize outside...
V-220831 Low Microsoft consumer experiences must be turned off. Microsoft consumer experiences provides suggestions and notifications to users, which may include the installation of Windows Store apps. Organizations may control the execution of applications through other means such as whitelisting. Turning off Microsoft consumer experiences will help prevent the unwanted installation of suggested applications.
V-220826 Low The Application Compatibility Program Inventory must be prevented from collecting data and sending the information to Microsoft. Some features may communicate with the vendor, sending system information or downloading data or components for the feature. Turning off this capability will prevent potentially sensitive information from being sent outside the enterprise and uncontrolled updates to the system. This setting will prevent the Program Inventory from collecting data about...
V-220825 Low The setting to allow Microsoft accounts to be optional for modern style apps must be enabled. Control of credentials and the system must be maintained within the enterprise. Enabling this setting allows enterprise credentials to be used with modern style apps that support this, instead of Microsoft accounts.
V-220798 Low The system must be configured to ignore NetBIOS name release requests except from WINS servers. Configuring the system to ignore name release requests, except from WINS servers, prevents a denial of service (DoS) attack. The DoS consists of sending a NetBIOS name release request to the server for each entry in the server's cache, causing a response delay in the normal operation of the servers...
V-220797 Low The system must be configured to prevent Internet Control Message Protocol (ICMP) redirects from overriding Open Shortest Path First (OSPF) generated routes. Allowing ICMP redirect of routes can lead to traffic not being routed properly. When disabled, this forces ICMP to be routed via shortest path first.
V-220715 Low Standard local user accounts must not exist on a system in a domain. To minimize potential points of attack, local user accounts, other than built-in accounts and local administrator accounts, must not exist on a workstation in a domain. Users must log on to workstations in a domain with their domain accounts.
V-220711 Low Unused accounts must be disabled or removed from the system after 35 days of inactivity. Outdated or unused accounts provide penetration points that may go undetected. Inactive accounts must be deleted if no longer necessary or, if still required, disabled until needed.
V-220700 Low Secure Boot must be enabled on Windows 10 systems. Secure Boot is a standard that ensures systems boot only to a trusted operating system. Secure Boot is required to support additional security features in Windows 10, including Virtualization Based Security and Credential Guard.
