In today’s fast-paced world of software development, the need for agility and speed is paramount. DevOps had emerged as a transformative approach to encourage collaboration between development and operation teams at an unprecedented pace. With DevOps, software companies can deliver high-quality products at an unprecedented pace.  

But, in the race for rapid deployment, there should be no risk in maintaining security. That is where DevSecOps: an amalgamation of development, security, and operations, entered. It’s not just a buzzword but a paradigm shift in our approach to software development.

Embark on a journey with me through this blog, where we delve into the intricacies of DevSecOps, uncovering how it surpasses traditional security measures.

What is DevSecOps?

In traditional software development, security measures are often implemented as a separate phase. This is mostly performed after the development is complete. DevSecOps seeks to break down the silos between – development, security, and operations by integrating security practices into every stage of the development process.

You might be wondering where it all began. Well, you can get the answer in the next section.

The Evolution of DevSecOps

The evolution from DevOps to DevSecOps marks a significant paradigm shift in response to the growing complexities of modern software development and the imperative need for enhanced security measures.

In the early 2010s, the advent of DevOps aimed to bridge the traditional gap between development and operations teams. To streamline the software development lifecycle (SDLC) these were the focus:

• Collaboration
• Communication
• Automation

This era witnessed the rise of Continuous Integration/Continuous Deployment (CI/CD) pipelines, enabling faster and more reliable software releases.

However, as the technological landscape evolved, it became apparent that integrating security into the development process was paramount.

This gave birth to the concept of DevSecOps by the mid-2010s. Two vital things became popular as this new concept gained prominence:

• The “shift-left” approach emerged, advocating for the early identification and mitigation of security issues.
• Automated security testing tools, such as static analysis, dynamic analysis, and interactive application security testing.

DevSecOps addressed the limitations of traditional security measures applied after development or during deployment. The goal was to embed security into the DevOps culture proactively.

By the late 2010s, organizations increasingly adopted DevSecOps to create a resilient and secure software development process.

This evolution represents a logical response to the changing technological landscape, emphasizing the importance of security in an era of continuous innovation and sophisticated cyber threats.
