Implementing Privileged Access Workstation

Implementing Privileged Access Workstation

Overview

A Privileged Access Workstation (PAW) is a hardened device dedicated to performing sensitive administrative tasks. This skill 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.

When to Use

Trigger phrases:

• "implementing privileged access workstation"

• "Design and implement Privileged Access Workstations (PAWs) with device hardening"

• When deploying or configuring implementing privileged access workstation capabilities in your environment

• When establishing security controls aligned to compliance requirements

• When building or improving security architecture for this domain

• When conducting security assessments that require this implementation

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

# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs(text: str) -> dict:
    return {k: re.findall(v, text) for k, v in IOC_PATTERNS.items()}

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

When NOT to Use

• You need to test the implementation (use performing-* skills)
• Task is about configuring existing tools (use configuring-* skills)
• You need to analyze security events (use analyzing-* skills)
• Task is about building detection rules (use building-* skills)
• You don't have access to the target environment
• Task requires vendor-specific expertise (consult vendor docs)

Red Flags

• Performing actions without explicit written authorization from the asset owner
• Testing against production systems without a defined scope and rules of engagement
• Modifying cloud IAM policies or security groups without approval
• Exposing cloud credentials or secrets in logs or reports
• Running scans that generate excessive API calls and trigger billing alerts

Process

1. Prepare — Gather requirements, verify prerequisites, set up environment
2. Execute — Run implementing privileged access workstation workflow with configured parameters
3. Verify — Validate output meets requirements, document results

Verification

• All steps executed successfully against a test environment before production use
• Output documented with screenshots or logs demonstrating expected behavior
• Cloud resource changes reverted or documented as intentional
• IAM policies reviewed for least-privilege compliance after testing
• No residual test resources left running (cost and security check)
