This playbook provides step-by-step remediation guidance for the 30 most common findings from internal penetration tests. Each finding includes the risk rating, implementation effort, exact commands and configurations, real-world gotchas, and verification steps. It is designed for IT administrators, system engineers, and security teams responsible for implementing fixes after a pentest.

5 Categories of Findings Covered

Organized by domain so you can assign the right team to the right fixes.

6 Findings

Network Protocols

LLMNR/NBT-NS poisoning, SMB signing, IPv6 DNS takeover, WPAD abuse, SNMP defaults, and cleartext protocol usage.

12 Findings

Active Directory

Kerberoasting, AS-REP roasting, unconstrained delegation, NTLM relay, Print Spooler, LAPS, password policy, GPP passwords, LDAP signing, and more.

4 Findings

Credential Management

Default credentials, cleartext passwords in shares, WDigest authentication, and LSASS protection with Credential Guard.

6 Findings

Host Security

2 Findings

SSL/TLS and Web

Weak SSL/TLS configurations and default web application pages and headers that leak technology stack information.

What's Inside Each Finding

Everything your team needs to fix the issue and verify it stays fixed.

Risk Rating and Effort Level

Critical, High, Medium, or Low severity paired with implementation effort so you can prioritize maximum impact for minimum work.

Copy-Paste Remediation Steps

Exact PowerShell commands, GPO paths, registry keys, and network device configurations. No guesswork required.

Real-World Gotchas

Warnings about what may break when you implement the fix. Legacy printers, VoIP phones, application dependencies — things that catch teams off guard.

Verification Commands

Commands to confirm the remediation was applied successfully. Run these after every change to validate before your retest.
