Shift Left is the term used to describe accounting for security from the earliest stages in a development lifecycle. This approach moves security considerations, testing, and validation activities earlier in the software development process, rather than treating security as an afterthought or final gate before deployment.

The concept of shifting left originates from the traditional software development timeline, where activities typically flow from left (early phases) to right (later phases). By shifting security activities to the left, organizations can identify and address vulnerabilities when they are less expensive and easier to fix.

Key principles of Shift Left security:

• Security by design: Incorporating security requirements during architecture and design phases
• Early threat modeling: Identifying potential security risks before implementation begins
• Secure coding practices: Training developers in security-aware programming techniques
• Automated security testing: Integrating security scans into CI/CD pipelines
• Security requirements: Defining security criteria alongside functional requirements

Benefits of Shift Left security:

• Reduced cost of fixing security vulnerabilities
• Faster time to market through early issue resolution
• Improved security posture of delivered applications
• Enhanced developer security awareness and skills
• Better integration of security into development workflows

Implementation strategies include:

• Security training for development teams
• Static Application Security Testing (SAST) in IDEs
• Dependency scanning for vulnerable components
• Security-focused code review processes
• Threat modeling workshops during design phases

Shift Left security is fundamental to DevSecOps practices, enabling organizations to build security into their development processes rather than bolting it on afterward.
