ISO 27001 Security Testing in Development and Acceptance

Introduction

The Security Testing in Development and Acceptance control ensures that security testing methodologies are integrated into the software development lifecycle (SDLC). This includes testing tools such as SAST (Static Application Security Testing), DAST (Dynamic Application Security Testing), penetration testing, and security acceptance testing. The goal is to identify and remediate vulnerabilities early in the development cycle before production deployment.

What This Control Is About (Basic Information)?

Control Title: Security Testing in Development and Acceptance
Control ID: UC-SE-888
Category: Security Testing
Subcategory: Application Security Testing
Version: v1.0

This control requires that security testing processes be defined and implemented throughout the SDLC. This includes integrating automated SAST and DAST tools in CI/CD pipelines, conducting regular penetration testing, and ensuring security acceptance testing occurs before production deployment.

Objective:
To integrate security testing methodologies into the software development lifecycle to identify and remediate vulnerabilities early, minimizing the risk of deploying insecure code into production.

Key Areas to Address:

• Automating SAST and DAST tools in CI/CD pipelines.
• Conducting regular penetration testing and security acceptance testing.
• Establishing acceptance criteria to ensure code is free from critical vulnerabilities before being promoted to production.

Implementation & Guidance

To successfully implement this control, organizations should focus on the following:

1. Automate SAST and DAST Tools in CI/CD Pipelines
   • Implement automated security testing tools such as SAST and DAST within continuous integration and continuous deployment (CI/CD) pipelines to ensure every code change is analyzed for security vulnerabilities.
     
     
2. Conduct Regular Penetration Testing
   • Perform regular penetration testing to identify vulnerabilities that automated tools might miss, simulating potential attack scenarios in a controlled environment.
     
     
3. Define Security Acceptance Criteria
   • Define clear security acceptance criteria, such as no critical or high vulnerabilities, that must be met before code is allowed to be deployed to production.
     
     
4. Security Acceptance Testing Before Deployment
   
   • Conduct a final security acceptance test before promoting code to production to ensure the code is free of security flaws and adheres to the established security standards.

Evidence Examples

Evidence that demonstrates the implementation of this control includes:

• Security Testing Reports: Reports from SAST, DAST, and penetration tests showing the results of security testing activities.
  
  
• Records of Vulnerability Remediation and Retesting: Logs showing vulnerabilities that were identified, remediated, and retested to ensure they were fixed.
  
  
• Security Testing Procedures and Policies: Documents outlining the security testing process, including policies for testing, vulnerability tracking, and remediation procedures.

Key Risks Addressed

This control addresses several risks including:

• Unpatched Vulnerabilities: Identifies and remediates security vulnerabilities before production deployment, reducing the risk of exploitation.
  
  
• Insecure Code Deployment: Ensures that only secure code is promoted to production, preventing the introduction of security flaws into the environment.
  
  
• Compliance Failures: Helps meet security standards by demonstrating proactive security testing, critical for audits and compliance with frameworks like ISO 27001.

Framework Mappings

Comply Agent shows strong cross-framework alignment:

1. Primary Mapping
   • ISO 27001 – A.8.29 (Exact Match)
     
     
2. Supporting Frameworks
   • SOC 2 – CC7.1 (Partial)
   • GDPR – Article 32 (Related)
   • ISO 27001 – A.8.29 (Exact Match)
     
     
3. Extended Mappings
   
   Comply Agent shows:
   • DORA – Article 11 & Article 12 (Enriched)
   • SOC 2 – CC1.2, CC6.1, CC6.2 (Enriched)
   • NIST CSF – DE.CM-4, PR.IP-1, PR.DS-5 (Enriched)

This demonstrates that security testing in development and acceptance is well-aligned with various frameworks, including SOC 2, NIST CSF, and GDPR, ensuring comprehensive application security across the SDLC.

Evidence Library

Comply Agent shows four key evidence categories:

1. Security Test Plans
   • Documents outlining the testing strategy, scope, and methodologies used for security testing in the development process.
     
     
2. Test Results
   • Records of security test outcomes, showing which vulnerabilities were found and whether they were remediated.
     
     
3. Vulnerability Reports
   • Detailed reports from SAST, DAST, and penetration testing, demonstrating detected vulnerabilities and their remediation status.
     
     
4. Testing Coverage Documentation
   • Documentation showing the coverage of security testing across the software components and ensuring all critical areas are tested.

This evidence ensures:

• A comprehensive and documented approach to security testing.
• Detailed vulnerability management through proactive testing and remediation.
• Traceable evidence of testing coverage, from planning to execution.

FAQs: ISO 27001 Security Testing in Development and Acceptance

1. What is the Security Testing in Development and Acceptance control?
   

   This control ensures that security testing is integrated into the SDLC using methods like SAST, DAST, penetration testing, and security acceptance testing to identify and remediate vulnerabilities early in development.
   
   

2. What is the objective of this control?
   

   The objective is to integrate security testing methodologies into the software development lifecycle, ensuring that vulnerabilities are identified and remediated before code is deployed to production.
   
   

3. What evidence is required for audits?

   Auditors will need security testing reports, records of vulnerability remediation, and security testing procedures and policies to confirm that security testing practices are properly implemented.
   
   

4. Who is responsible for this control?
   

   The Security Team is responsible for ensuring security testing activities are implemented and followed, and that vulnerabilities are tracked and remediated.
   
   

5. How often should security testing be conducted?
   

   Security testing should be performed regularly, ideally at least once per quarter, and before code is promoted to production.
   
   

6. What are the risks if security testing is not integrated into the SDLC?
   

   Without proper security testing, vulnerabilities could go undetected, leading to the deployment of insecure code and potentially exposing the organization to cyber threats and compliance failures.
