Microsoft Windows Server 2022 Security Technical Implementation Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • Windows Server 2022 must not have the Telnet Client installed.

    Unnecessary services increase the attack surface of a system. Some of these services may not support required levels of authentication or encryption or may provide unauthorized access to the system.
    Rule Medium Severity
  • Windows Server 2022 must not have Windows PowerShell 2.0 installed.

    Windows PowerShell 5.x added advanced logging features that can provide additional detail when malware has been run on a system. Disabling the Windows PowerShell 2.0 mitigates against a downgrade a...
    Rule Medium Severity
  • Windows Server 2022 systems must have Unified Extensible Firmware Interface (UEFI) firmware and be configured to run in UEFI mode, not Legacy BIOS.

    UEFI provides additional security features in comparison to legacy BIOS firmware, including Secure Boot. UEFI is required to support additional security features in Windows, including Virtualizatio...
    Rule Medium Severity
  • Windows Server 2022 password history must be configured to 24 passwords remembered.

    A system is more vulnerable to unauthorized access when system users recycle the same password several times without being required to change to a unique password on a regularly scheduled basis. Th...
    Rule Medium Severity
  • Windows Server 2022 maximum password age must be configured to 60 days or less.

    The longer a password is in use, the greater the opportunity for someone to gain unauthorized knowledge of the passwords. Scheduled changing of passwords hinders the ability of unauthorized system ...
    Rule Medium Severity
  • Windows Server 2022 minimum password age must be configured to at least one day.

    Permitting passwords to be changed in immediate succession within the same day allows users to cycle passwords through their history database. This enables users to effectively negate the purpose o...
    Rule Medium Severity
  • Windows Server 2022 must have the built-in Windows password complexity policy enabled.

    The use of complex passwords increases their strength against attack. The built-in Windows password complexity policy requires passwords to contain at least three of the four types of characters (n...
    Rule Medium Severity
  • Windows Server 2022 reversible password encryption must be disabled.

    Storing passwords using reversible encryption is essentially the same as storing clear-text versions of the passwords, which are easily compromised. For this reason, this policy must never be enabled.
    Rule High Severity
  • Windows Server 2022 permissions for the Application event log must prevent access by nonprivileged accounts.

    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. A...

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
