Software Development Security within CISSP refers to the systematic approach of building security throughout the software development lifecycle (SDLC). It encompasses practices, tools, and methodologies to create secure applications from inception through maintenance.
The secure SDLC integrates security at every phase:
1. Requirements phase: Establishing security requirements, compliance needs, and threat modeling early.
2. Design phase: Implementing secure architecture principles, defense-in-depth strategies, and performing security design reviews.
3. Development phase: Following secure coding standards, conducting code reviews, and using static application security testing (SAST).
4. Testing phase: Performing dynamic application security testing (DAST), penetration testing, and fuzz testing to identify vulnerabilities.
5. Deployment phase: Secure configuration management, hardening systems, and validating security controls.
6. Maintenance phase: Vulnerability management, patch management, and continuous security monitoring.
Key security concepts include:
• Input validation to prevent injection attacks
• Authentication and authorization mechanisms
• Session management best practices
• Error handling that doesn't leak sensitive information
• Database security principles
• API security
• Cryptography implementation
Secure development methodologies like DevSecOps integrate security into agile and DevOps processes, emphasizing automation and continuous security testing.
Common vulnerabilities addressed include OWASP Top 10 risks like injection flaws, broken authentication, sensitive data exposure, and cross-site scripting.
The goal is to shift security "left" in the development process, finding and fixing vulnerabilities earlier when remediation costs are lower, reducing risk, ensuring compliance, and building trust with customers through demonstrably secure software.Software Development Security within CISSP refers to the systematic approach of building security throughout the software development lifecycle (SDLC).
