The reconstructed evaluation script behind this rule's OVAL check(s) — every module a compound check combines, with this rule's own concrete values and DISA's SCC tool's real per-module mechanism curated from static teardown of SCC releases.
# Windows PowerShell
# Reconstructed from oval:mil.disa.fso.windows:def:5196
# Anonymous access to the registry must be restricted.
# Per-module read mechanism curated from static teardown of DISA's SCC tool
# (SCAP Compliance Checker) -- see the SCC Automation Reference above.
#
# MANUAL REVIEW REQUIRED -- the module(s) below could not be reconstructed
# into working code from curated SCC reference data, and are excluded from
# the automated result:
# - regkeyeffectiverights53_object (regkeyeffectiverights53_test) -- Winreg key has no non-(admin,backup,localsvc,system) rights to check: <set> composition (base object oval:mil.disa.fso.windows:obj:519602): member unresolved -- no extractor for field "key_wow64_res"
# - regkeyeffectiverights53_object (regkeyeffectiverights53_test) -- Winreg key has no bad rights for non-(admin,backup,localsvc,system): <set> composition (base object oval:mil.disa.fso.windows:obj:519602): member unresolved -- cannot derive an existence probe for this object type
# - regkeyeffectiverights53_object (regkeyeffectiverights53_test) -- Winreg key has no non-admin rights to check: <set> composition (base object oval:mil.disa.fso.windows:obj:519602): member unresolved -- no extractor for field "key_wow64_res"

} Assessment Script Powered by AISyntax-verified
A standalone PowerShell script to assess this control automatically. Review before running it in your environment.
Syntax-checked as valid PowerShell. Not executed here — running it for real needs the actual ms_windows_2012_and_2012_r2_dc target this check assesses.
