7 Stages of the DevSecOps Model and 6 Critical Best Practices

What Is DevOps Security (DevSecOps)? 

DevOps security, or DevSecOps, integrates security practices into the DevOps pipeline. It ensures that security is a shared responsibility across development, operations, and security teams rather than being siloed. This approach automates security checks at every stage, enhancing software development’s speed and reliability by identifying vulnerabilities early in the lifecycle. Tools used in DevSecOps help manage security without slowing down the development process, creating a balance between rapid delivery and security.

Adopting DevSecOps means shifting security focus from the end of the development process to the beginning. Early security integration saves time and resources by reducing the need for significant changes post-development. This approach promotes a proactive security stance, increasing collaboration among teams. By ensuring that security is built into the development process, organizations can respond to threats more efficiently.

What Are the Benefits of DevSecOps?

Regular training and awareness programs support this cultural shift, ensuring everyone is informed and proactive about potential threats and vulnerabilities.

Such a culture not only improves overall security posture but also fosters collaboration and ownership among teams. Security becomes everyone’s responsibility rather than isolated to specific roles.

DevSecOps vs. SecDevOps vs. DevOps: What Is the Difference? 

While DevOps, DevSecOps, and SecDevOps all focus on improving collaboration and speeding up the software development lifecycle, their emphasis on security differs.

• DevOps integrates development (Dev) and operations (Ops) to streamline software delivery. The primary focus is on improving communication and automating processes between development and operations teams to release software faster and with fewer errors. Security is often considered at the final stages, sometimes leading to vulnerabilities being discovered late in the process.
• DevSecOps adds security (Sec) into the mix, embedding security practices throughout the DevOps pipeline. Security becomes a shared responsibility, with teams incorporating security checks and tests from the planning stages through to deployment and operations.
• SecDevOps places an even stronger emphasis on security, making it the primary focus before development and operations activities. While similar to DevSecOps, this model ensures that security leads every process, and it is prioritized even more aggressively. This can sometimes slow down the development process, but the goal is to ensure the highest level of security from the outset.
