Assessment Title

Rule Text

Unauthorized accounts must not have the Access this computer from the network user right on domain controllers.

Description

Discussion Text

Inappropriate granting of user rights can provide system, administrative, and other high-level capabilities. Accounts with the "Access this computer from the network" right may access resources on the system and should be limited to those requiring it.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Checks

DISA STIG (Manual Reference)

Verify the effective setting in Local Group Policy Editor.
Run "gpedit.msc".

Navigate to Local Computer Policy -> Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> User Rights Assignment.

If any accounts or groups other than the following are granted the "Access this computer from the network" right, this is a finding:

Administrators
Authenticated Users
Enterprise Domain Controllers

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.

# OVAL Definition: oval:mil.disa.fso.windows:def:4704
$compliant = (Get-CimInstance -ClassName Win32_LocalSystemGroupMembershipPolicy).LocalGroupMember -notcontains "Administrators","Authenticated Users","Enterprise Domain Controllers"

Remediation

Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> User Rights Assignment -> "Access this computer from the network" to only include the following accounts or groups:

Administrators
Authenticated Users
Enterprise Domain Controllers

Severity Override Guidance: If an application requires this user right, this can be downgraded to not a finding if the following conditions are met:
- Vendor documentation must support the requirement for having the user right.
- The requirement must be documented with the ISSO.
- The application account must meet requirements for application account passwords, such as length (V-36661) and required changes frequency (V-36662).
