Systems at unsupported versions or releases of an operating system will not receive security updates for new vulnerabilities which leaves them subject to exploitation. Systems must be maintained at a version of the operating system supported by the vendor with new security updates.
Fix: F-69303r2_fix

Update the system to a version of the operating system supported by the vendor. Support for the initial release of Windows 8 ended 12 January 2016. After this date, systems must have Windows 8.1 installed.

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.
Fix: F-63549r1_fix

If the system is not a member of a domain, this is NA.

Inappropriate granting of user rights can provide system, administrative, and other high level capabilities.

In an Active Directory Domain, denying logons to the Enterprise Admins and Domain Admins groups on lower trust systems helps mitigate the risk of privilege escalation from credential theft attacks which could lead to the compromise of an entire domain. Local accounts on domain-joined systems must also be assigned this right to decrease the risk of lateral movement resulting from credential theft attacks. The Guests group must be assigned this right to prevent unauthenticated access.

Allowing autoplay to execute may introduce malicious code to a system. Autoplay begins reading from a drive as soon as you insert media in the drive. As a result, the setup file of programs or music on audio media may start. By default, autoplay is disabled on removable drives, such as the floppy disk drive (but not the CD-ROM drive) and on network drives. If you enable this policy, you can also disable autoplay on all drives.

Maintaining an audit trail of system activity logs can help identify configuration errors, troubleshoot service disruptions, and analyze compromises that have occurred, as well as detect attacks. Audit logs are necessary to provide a trail of evidence in case the system or network is compromised. Collecting this data is essential for analyzing the security of information assets and detecting signs of suspicious and unexpected behavior. Enabling "Include command line data for process creation events" will record the command line information with the process creation events in the log. This can provide additional detail when malware has run on a system.

Attackers are constantly looking for vulnerabilities in systems and applications. Data Execution Prevention (DEP) prevents harmful code from running in protected memory locations reserved for Windows and other programs.

Configure DEP to at least OptOut. 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. Note: Suspend BitLocker before making changes to the DEP configuration. 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. Select the "Data Execution Prevention" tab. Applications that are opted out are configured in the window below the selection "Turn on DEP for all programs and services except those I select:".

SMBv1 is a legacy protocol that uses the MD5 algorithm as part of SMB. MD5 is known to be vulnerable to a number of attacks such as collision and preimage attacks as well as not being FIPS compliant. Disabling SMBv1 support may prevent access to file or print sharing resources with systems or devices that only support SMBv1. File shares and print services hosted on Windows Server 2003 are an example, however Windows Server 2003 is no longer a supported operating system. Some older network attached devices may only support SMBv1.
