DevSecOps: Integrating Security into the Entire SDLC

The Core Principles of DevSecOps

• Security as Everyone’s Responsibility: Security is a shared responsibility across development, security, and operations teams.
• Shift Left: Security activities are implemented earlier in the development process.
• Automation and Tooling: Security tools and processes are integrated into the CI/CD pipeline.
• Collaboration and Communication: Effective communication between teams is essential.
• Continuous Feedback and Improvement: Security practices are continuously monitored and improved.
• Embrace Change and Agility: Aligning with agile and DevOps methodologies.
