SEC11-BP03: Perform regular penetration testing

Overview

Conduct regular penetration testing to validate the effectiveness of security controls and identify vulnerabilities that automated tools might miss. Penetration testing should be performed by qualified security professionals using a combination of automated tools and manual techniques to simulate real-world attack scenarios.

Implementation Guidance

Penetration testing is a critical component of a comprehensive security testing strategy that goes beyond automated vulnerability scanning. While automated tools can identify known vulnerabilities and misconfigurations, penetration testing provides a human element that can discover complex attack chains, business logic flaws, and novel attack vectors that automated tools might miss.

Key Principles of Penetration Testing

Risk-Based Approach: Focus penetration testing efforts on the most critical assets and highest-risk attack vectors based on threat modeling and risk assessment results.

Regular Cadence: Establish a regular penetration testing schedule that aligns with your development cycles, major releases, and compliance requirements.

Comprehensive Scope: Include all layers of your application stack, from infrastructure and network components to application logic and user interfaces.

Realistic Attack Simulation: Use testing methodologies that simulate real-world attack scenarios and adversary tactics, techniques, and procedures (TTPs).

Actionable Results: Ensure penetration testing produces clear, actionable findings with specific remediation guidance and business risk context.

Implementation Steps

Step 1: Establish Penetration Testing Program Framework

Create a comprehensive framework for managing penetration testing activities:

Step 2: Manage External Penetration Testing Vendors

Establish processes for selecting, managing, and working with external penetration testing vendors:

Step 3: Implement Penetration Testing Results Management

Create comprehensive systems for managing penetration testing results and remediation:

Step 4: Integrate with AWS Security Services

Leverage AWS services to enhance penetration testing capabilities and results management:

Best Practices for Penetration Testing

1. Establish Clear Scope and Objectives

Define Testing Scope: Clearly define what systems, applications, and networks are in scope for testing, as well as any exclusions or limitations.

Set Clear Objectives: Establish specific goals for each penetration test, such as validating specific controls, testing incident response, or meeting compliance requirements.

Document Rules of Engagement: Create detailed rules of engagement that specify testing methods, timing, communication protocols, and emergency procedures.

2. Use Risk-Based Testing Approach

Prioritize High-Risk Assets: Focus testing efforts on the most critical and high-risk systems and applications.

Threat-Informed Testing: Base testing scenarios on relevant threat intelligence and known attack patterns for your industry.

Business Context: Consider business impact and criticality when planning tests and interpreting results.

3. Combine Multiple Testing Approaches

Black Box, Gray Box, and White Box: Use different testing approaches to get comprehensive coverage and validate security from multiple perspectives.

Internal and External Testing: Conduct both external (internet-facing) and internal (insider threat) penetration tests.

Automated and Manual Testing: Combine automated tools with manual testing techniques to achieve thorough coverage.

4. Ensure Quality and Accuracy

Qualified Testers: Use experienced, certified penetration testers with relevant expertise for your environment.

Methodology Standards: Follow established methodologies like OWASP, NIST, or PTES to ensure comprehensive and consistent testing.

Quality Assurance: Implement quality assurance processes to validate findings and reduce false positives.
