Secure Software Development Lifecycle (SSDLC)

The Secure Software Development Lifecycle (SSDLC) is a systematic approach to building security into software applications from the initial design phase through deployment and maintenance.

What is SSDLC?

SSDLC integrates security practices into each phase of the software development process, ensuring that security is not an afterthought but a fundamental component of the development workflow.

SSDLC Phases

Core Security Principles

1. Security by Design

• Integrate security considerations from the beginning
• Apply defense in depth strategies
• Implement least privilege principles

2. Continuous Security

• Regular security assessments throughout development
• Automated security testing in CI/CD pipelines
• Ongoing vulnerability management

3. Threat Modeling

• Identify potential threats and attack vectors
• Assess risk levels and prioritize mitigations
• Document security requirements

SSDLC Framework Components

Security Training

• Developer security awareness programs
• Secure coding training and certifications
• Regular security updates and best practices

Security Tools Integration

• Static Application Security Testing (SAST)
• Dynamic Application Security Testing (DAST)
• Interactive Application Security Testing (IAST)
• Software Composition Analysis (SCA)

Security Governance

• Security policies and procedures
• Code review security checklists
• Security incident response procedures
• Compliance and audit requirements

Implementation Benefits

• Reduced Security Vulnerabilities: Early detection and prevention of security issues
• Cost Savings: Lower remediation costs compared to post-deployment fixes
• Compliance: Meet regulatory and industry security requirements
• Customer Trust: Demonstrate commitment to security
• Competitive Advantage: Differentiate through security excellence
