Vuln Rule Version CCI Severity Title Description
SV-220697r569187_rule WN10-00-000005 CCI-000366 MEDIUM Domain-joined systems must use Windows 10 Enterprise Edition 64-bit version. 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 10 Enterprise 64-bit version.
SV-220702r569228_rule WN10-00-000030 CCI-001199 MEDIUM Windows 10 information systems must use BitLocker to encrypt all disks to protect the confidentiality and integrity of all information at rest. 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.
SV-220706r569217_rule WN10-00-000040 CCI-000366 HIGH Windows 10 systems must be maintained at a supported servicing level. Windows 10 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.
SV-220708r569187_rule WN10-00-000050 CCI-000213 HIGH Local volumes must be formatted using NTFS. The ability to set access permissions and auditing is critical to maintaining the security and proper access controls of a system. To support this, volumes must be formatted using the NTFS file system.
SV-220716r569187_rule WN10-00-000090 CCI-000199 MEDIUM Accounts must be configured to require password expiration. Passwords that do not expire increase exposure with a greater probability of being discovered or cracked.
SV-220718r569187_rule WN10-00-000100 CCI-000381 HIGH Internet Information System (IIS) or its subcomponents must not be installed on a workstation. Installation of Internet Information System (IIS) may allow unauthorized internet services to be hosted. Websites must only be hosted on servers that have been designed for that purpose and can be adequately secured.
SV-220719r569187_rule WN10-00-000105 CCI-000382 MEDIUM Simple Network Management Protocol (SNMP) must not be installed on the system. Some protocols and services do not support required security features, such as encrypting passwords or traffic.
SV-220720r569187_rule WN10-00-000110 CCI-000381 MEDIUM Simple TCP/IP Services must not be installed on the system. Some protocols and services do not support required security features, such as encrypting passwords or traffic.
SV-220721r569187_rule WN10-00-000115 CCI-000382 MEDIUM The Telnet Client must not be installed on the system. Some protocols and services do not support required security features, such as encrypting passwords or traffic.
SV-220722r569187_rule WN10-00-000120 CCI-000382 MEDIUM The TFTP Client must not be installed on the system. Some protocols and services do not support required security features, such as encrypting passwords or traffic.
SV-220726r569187_rule WN10-00-000145 CCI-002824 HIGH Data Execution Prevention (DEP) must be configured to at least OptOut. 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.
SV-220727r569187_rule WN10-00-000150 CCI-002824 HIGH Structured Exception Handling Overwrite Protection (SEHOP) must be enabled. Attackers are constantly looking for vulnerabilities in systems and applications. Structured Exception Handling Overwrite Protection (SEHOP) blocks exploits that use the Structured Exception Handling overwrite technique, a common buffer overflow attack.
SV-220728r569187_rule WN10-00-000155 CCI-000381 MEDIUM The Windows PowerShell 2.0 feature must be disabled on the system. Windows PowerShell 5.0 added advanced logging features which can provide additional detail when malware has been run on a system. Disabling the Windows PowerShell 2.0 mitigates against a downgrade attack that evades the Windows PowerShell 5.0 script block logging feature.
SV-220729r569187_rule WN10-00-000160 CCI-000381 MEDIUM The Server Message Block (SMB) v1 protocol must be disabled on the system. 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 Storage (NAS) devices may only support SMBv1.
SV-220730r569187_rule WN10-00-000165 CCI-000381 MEDIUM The Server Message Block (SMB) v1 protocol must be disabled on the SMB server.

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.
SV-220731r569187_rule WN10-00-000170 CCI-000381 MEDIUM The Server Message Block (SMB) v1 protocol must be disabled on the SMB client. 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.
SV-220732r569187_rule WN10-00-000175 CCI-000381 MEDIUM The Secondary Logon service must be disabled on Windows 10. The Secondary Logon service provides a means for entering alternate credentials, typically used to run commands with elevated privileges. Using privileged credentials in a standard user session can expose those credentials to theft.
SV-220739r569187_rule WN10-AC-000005 CCI-002238 MEDIUM Windows 10 account lockout duration must be configured to 15 minutes or greater. The account lockout feature, when enabled, prevents brute-force password attacks on the system. This parameter specifies the amount of time that an account will remain locked after the specified number of failed logon attempts.
SV-220740r569187_rule WN10-AC-000010 CCI-000044 MEDIUM The number of allowed bad logon attempts must be configured to 3 or less. The account lockout feature, when enabled, prevents brute-force password attacks on the system. The higher this value is, the less effective the account lockout feature will be in protecting the local system. The number of bad logon attempts must be reasonably small to minimize the possibility of a successful password attack, while allowing for honest errors made during a normal user logon.
SV-220741r569187_rule WN10-AC-000015 CCI-000044 MEDIUM The period of time before the bad logon counter is reset must be configured to 15 minutes. The account lockout feature, when enabled, prevents brute-force password attacks on the system. This parameter specifies the period of time that must pass after failed logon attempts before the counter is reset to 0. The smaller this value is, the less effective the account lockout feature will be in protecting the local system.
SV-220742r569187_rule WN10-AC-000020 CCI-000200 MEDIUM The 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 a password to a unique password on a regularly scheduled basis. This enables users to effectively negate the purpose of mandating periodic password changes. The default value is 24 for Windows domain systems. DoD has decided this is the appropriate value for all Windows systems.
SV-220743r569187_rule WN10-AC-000025 CCI-000199 MEDIUM The 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 users to crack passwords and gain access to a system.
SV-220744r569187_rule WN10-AC-000030 CCI-000198 MEDIUM The minimum password age must be configured to at least 1 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 of mandating periodic password changes.
SV-220745r569187_rule WN10-AC-000035 CCI-000205 MEDIUM Passwords must, at a minimum, be 14 characters. Information systems not protected with strong password schemes (including passwords of minimum length) provide the opportunity for anyone to crack the password, thus gaining access to the system and compromising the device, information, or the local network.
SV-220746r569187_rule WN10-AC-000040 CCI-000192 MEDIUM The built-in Microsoft password complexity filter must be enabled. The use of complex passwords increases their strength against guessing and brute-force attacks. This setting configures the system to verify that newly created passwords conform to the Windows password complexity policy.
SV-220747r569187_rule WN10-AC-000045 CCI-000196 HIGH Reversible password encryption must be disabled. Storing passwords using reversible encryption is essentially the same as storing clear-text versions of the passwords. For this reason, this policy must never be enabled.
SV-220748r569187_rule WN10-AU-000005 CCI-000172 MEDIUM The system must be configured to audit Account Logon - Credential Validation failures.
