Secure Software Development (SSDLC)
Secure Software Development Life Cycle (SSDLC) refers to the integration of security practices and measures throughout all phases of software development, from initial planning and design to deployment and maintenance. By embedding security at every stage, SSDLC aims to identify and address vulnerabilities early, reduce risks, and ensure the final product is robust against cyber threats. This proactive approach helps organizations deliver safer, more reliable software to users.

💡 Key Takeaways
- Define SSDLC and why security belongs in every software development phase.
- Map security activities to SDLC phases (planning, design, development, testing, deployment, maintenance).
- Learn core practices: threat modeling, secure coding, and security testing to find vulnerabilities early (SAST/DAST).
- Explore implementing a secure DevSecOps workflow with governance and ongoing monitoring.
❓ Frequently Asked Questions
What is SSDLC and why is it used?
SSDLC stands for Secure Software Development Life Cycle. It integrates security practices into every phase of software development—from planning to maintenance—so vulnerabilities are identified and fixed early.
What are the main phases of SSDLC?
Planning/requirements, design, implementation (coding), verification/testing, deployment, and maintenance, with security activities at each stage such as threat modeling, secure coding, code reviews, security testing, and monitoring.
How does SSDLC reduce risk and cost?
By discovering and addressing security issues early, it lowers the chance of breaches, reduces post-release fixes, and helps with compliance and trust.
What are common practices in SSDLC?
Threat modeling in design, secure coding standards, regular code reviews, automated security testing (SAST/DAST/IAST), vulnerability management, and ongoing security updates during maintenance.
