Implementing Privileged Access Workstation

Overview

A Privileged Access Workstation (PAW) is a hardened device dedicated to performing sensitive administrative tasks. This guide covers PAW design using the tiered administration model, device compliance enforcement via Microsoft Intune or Group Policy, just-in-time (JIT) access provisioning, and integration with privileged access management (PAM) platforms like CyberArk and BeyondTrust.

Prerequisites

• Windows 10/11 Enterprise with Virtualization Based Security (VBS)
• Microsoft Intune or Active Directory Group Policy
• CyberArk Privileged Access Security or BeyondTrust Password Safe (optional)
• Python 3.9+ with requests, subprocess, json
• Administrative access to target endpoints

Steps

1. Audit current privileged access patterns and identify Tier 0/1/2 assets
2. Configure device hardening baselines (AppLocker, Credential Guard, Device Guard)
3. Enforce compliance policies via Intune or GPO
4. Implement just-in-time access with time-limited admin group membership
5. Integrate with CyberArk/BeyondTrust for credential vaulting
6. Validate PAW configuration against CIS and Microsoft PAW guidance
7. Monitor privileged sessions and generate compliance reports

Expected Output

• JSON report listing device compliance status, hardening checks, JIT access windows, and PAM integration verification
• Risk scoring per workstation with remediation recommendations

Verification Criteria

Confirm successful execution by validating:

• [ ] All prerequisite tools and access requirements are satisfied
• [ ] Each workflow step completed without errors
• [ ] Output matches expected format and contains expected data
• [ ] No security warnings or misconfigurations detected
• [ ] Results are documented and evidence is preserved for audit

Compliance Framework Mapping

This skill supports compliance evidence collection across multiple frameworks:

• SOC 2: CC6.1 (Logical Access), CC6.2 (Credentials), CC6.3 (Provisioning)
• ISO 27001: A.9.1 (Access Control), A.9.2 (User Access Management), A.9.4 (System Access Control)
• NIST 800-53: AC-2 (Account Management), IA-2 (Identification), AC-6 (Least Privilege)
• NIST CSF: PR.AC (Access Control)

Claw GRC Tip: When this skill is executed by a registered agent, compliance evidence is automatically captured and mapped to the relevant controls in your active frameworks.

Deploying This Skill with Claw GRC

Agent Execution

Register this skill with your Claw GRC agent for automated execution:

# Install via CLI
npx claw-grc skills add implementing-privileged-access-workstation

# Or load dynamically via MCP
grc.load_skill("implementing-privileged-access-workstation")

Audit Trail Integration

When executed through Claw GRC, every step of this skill generates tamper-evident audit records:

• SHA-256 chain hashing ensures no step can be modified after execution
• Evidence artifacts (configs, scan results, logs) are automatically attached to relevant controls
• Trust score impact — successful execution increases your agent's trust score

Continuous Compliance

Schedule this skill for recurring execution to maintain continuous compliance posture. Claw GRC monitors for drift and alerts when re-execution is needed.
