Pentest Checklist

Purpose

Provide a comprehensive checklist for planning, executing, and following up on penetration tests. Ensure thorough preparation, proper scoping, and effective remediation of discovered vulnerabilities.

Inputs/Prerequisites

• Clear business objectives for testing
• Target environment information
• Budget and timeline constraints
• Stakeholder contacts and authorization
• Legal agreements and scope documents

Outputs/Deliverables

• Defined pentest scope and objectives
• Prepared testing environment
• Security monitoring data
• Vulnerability findings report
• Remediation plan and verification

Core Workflow

Phase 1: Scope Definition

Define Objectives

• Clarify testing purpose - Determine goals (find vulnerabilities, compliance, customer assurance)
• Validate pentest necessity - Ensure penetration test is the right solution
• Align outcomes with objectives - Define success criteria

Reference Questions:

• Why are you doing this pentest?
• What specific outcomes do you expect?
• What will you do with the findings?

Know Your Test Types

Enumerate Likely Threats

• Identify high-risk areas - Where could damage occur?
• Assess data sensitivity - What data could be compromised?
• Review legacy systems - Old systems often have vulnerabilities
• Map critical assets - Prioritize testing targets

Define Scope

• List in-scope systems - IPs, domains, applications
• Define out-of-scope items - Systems to avoid
• Set testing boundaries - What techniques are allowed?
• Document exclusions - Third-party systems, production data

Budget Planning

Budget Reality Check:

• Cheap pentests often produce poor results
• Align budget with asset criticality
• Consider ongoing vs. one-time testing

Phase 2: Environment Preparation

Prepare Test Environment

• Production vs. staging decision - Determine where to test
• Set testing limits - No DoS on production
• Schedule testing window - Minimize business impact
• Create test accounts - Provide appropriate access levels

Environment Options:

Production  - Realistic but risky
Staging     - Safer but may differ from production
Clone       - Ideal but resource-intensive

Run Preliminary Scans

• Execute vulnerability scanners - Find known issues first
• Fix obvious vulnerabilities - Don't waste pentest time
• Document existing issues - Share with testers

Common Pre-Scan Tools:

# Network vulnerability scan
nmap -sV --script vuln TARGET

# Web vulnerability scan
nikto -h http://TARGET

Review Security Policy

• Verify compliance requirements - GDPR, PCI-DSS, HIPAA
• Document data handling rules - Sensitive data procedures
• Confirm legal authorization - Get written permission

Notify Hosting Provider

• Check provider policies - What testing is allowed?
• Submit authorization requests - AWS, Azure, GCP requirements
• Document approvals - Keep records

Cloud Provider Policies:

• AWS: https://aws.amazon.com/security/penetration-testing/
• Azure: https://docs.microsoft.com/security/pentest
• GCP: https://cloud.google.com/security/overview

Freeze Developments

• Stop deployments during testing - Maintain consistent environment
• Document current versions - Record system states
• Avoid critical patches - Unless security emergency

Phase 3: Expertise Selection

Find Qualified Pentesters

• Seek recommendations - Ask trusted sources
• Verify credentials - OSCP, GPEN, CEH, CREST
• Check references - Talk to previous clients
• Match expertise to scope - Web, network, mobile specialists

Evaluation Criteria:

Define Methodology

• Select testing standard - PTES, OWASP, NIST
• Determine access level - Black box, gray box, white box
• Agree on techniques - Manual vs. automated t
