SEC11: How do you incorporate and validate the security properties of applications throughout the design, development, and deployment lifecycle?

Training people, testing your security properties, and validating that you are meeting your security requirements are key elements to consider when developing any application. Adopting application security testing as a regular part of your software development lifecycle (SDLC) and post-deployment processes help validate that you're implementing security controls properly. Your application security testing should also be performed regularly as part of your security assessment processes.

Best Practices

This question includes the following best practices:

Key Concepts

Application Security Fundamentals

Security by Design: Integrate security considerations from the earliest stages of application design and architecture. Security should be a fundamental requirement, not an afterthought added during or after development.

Shift-Left Security: Move security testing and validation activities earlier in the development lifecycle. Early detection and remediation of security issues is more cost-effective and reduces risk.

DevSecOps Integration: Seamlessly integrate security practices, tools, and responsibilities into DevOps workflows. Security becomes everyone’s responsibility, not just the security team’s.

Continuous Security Validation: Implement ongoing security testing and validation throughout the application lifecycle, from development through production deployment and maintenance.

Application Security Lifecycle

Design Phase: Incorporate threat modeling, security requirements definition, and secure architecture design. Establish security controls and design patterns that will be implemented throughout development.

Development Phase: Implement secure coding practices, conduct code reviews, and perform static application security testing (SAST). Ensure developers have the training and tools needed for secure development.

Testing Phase: Execute comprehensive security testing including dynamic application security testing (DAST), interactive application security testing (IAST), and dependency scanning.

Deployment Phase: Validate security configurations, perform final security assessments, and ensure secure deployment practices. Implement runtime application self-protection (RASP) where appropriate.

Operations Phase: Maintain ongoing security monitoring, conduct regular security assessments, and respond to newly discovered vulnerabilities in production applications.
