Overview
This module applies CIS benchmark hardening to:
- Windows 10: Configurable, defaulted to domain-joined Level 1 & 2 + NG + BL (currently v3.0.0)
- Windows 11: Configurable, defaulted to domain-joined Level 1 & 2 + BL (currently v3.0.0)
It also configures additional system resources as described below
Description
Windows CIS controls and other resources are applied using registry, security policy, audit policy, optional local group policy (for HKCU controls), execs and dependency modules.
Building on CIS controls
Additional resources are also defined, including:
Windows 10 / 11
- remote desktop
- users
- firewall (limited)
Other Windows 10 / 11 parameters include:
- cis_profile_type
- cis_enforcement_level
- cis_include_bitlocker
- cis_include_nextgen
- cis_exclude_rules
- catalog_no_cache
- clear_temp_files
- enable_administrator
- purge_unmanaged_users
- performance_powerscheme
- enable_remote_desktop
Defence in-depth
This module takes a defence in-depth approach, with the following built-in functions:
- undefined users are purged (except system users)
- where CIS recommendations have more than 1 acceptable setting, the more stringent is used
Beginning with cis_security_hardening_windows
To use this module, include cis_security_hardening_windows in your Node Classifier (ENC) or wrapping class.
At minimum, the following hiera must be provided to the module:
Windows 10 / 11:
cis_security_hardening_windows::logon_banner(string)cis_security_hardening_windows::logon_message(string)cis_security_hardening_windows::disabled_administrator_newname(string)cis_security_hardening_windows::disabled_administrator_newpassword(string)cis_security_hardening_windows::disabled_guest_newname(string)cis_security_hardening_windows::users(hash) is required as built-in administrator will be disabled
See example minimum hiera data here
CIS Enforcement Levels
- All recommended domain-joined Level 1 & 2 + NG + BL CIS controls are enforced by default using module hiera (standalone selectable)
- HKCU registry entries are also optionally applied by copying a preconfigured
Registry.polfile toC:/Windows/System32/GroupPolicy/ - Comments in module hiera identify the objective of each setting however CIS reference numbers are not shown as they are subject to change
- Profile Type, Enforcement Level (1 or 2 (1+2)), BitLocker (BL), NextGen (NG) and HKCU policy inclusion are parameterised:
cis_security_hardening_windows:cis_profile_type: 'domain' cis_security_hardening_windows::cis_enforcement_level: 2 cis_security_hardening_windows::cis_include_bitlocker: true cis_security_hardening_windows::cis_include_nextgen: true cis_security_hardening_windows::cis_include_hkcu: true - A reference list of rules enforced via the system registry is in the hiera folder for each Windows version, eg here. Note that some additional rules are applied by Local Security Policy and Audit Policy resources however.
- Individual controls can be overridden by any of the following methods:
- creating a optional hiera array for
cis_security_hardening_windows::cis_exclude_rulescontaining rule titles to be subtracted from the default included hashes (note however that some rules are enforced by the local_security_policy or windows_firewall modules):cis_security_hardening_windows::cis_exclude_rules: - "(L1) Ensure 'Allow users to enable online speech recognition services is set to 'Disabled'" - "(L1) Ensure 'Configure Solicited Remote Assistance' is set to 'Disabled'" - creating a hiera hash containing registry keys with different values at a higher precedence (eg domain or node) and titled any of:
cis_security_hardening_windows::cis_level_1 (or windows_standalone) cis_security_hardening_windows::cis_level_2 (or windows_standalone) cis_security_hardening_windows::cis_bitlocker (or windows_standalone) cis_security_hardening_windows::cis_nextgen (or windows_standalone) - other methods such as resource collectors to override registry key values if wrapping this module into your own classes
- creating a optional hiera array for
