The Dawn of DevSecOps

In the dazzling dawn of the digital world, a revolutionary approach to software development has emerged, known as DevSecOps. This approach is an expansion of DevOps, which integrates software development (Dev) and IT operations (Ops). But DevSecOps takes this a step further by folding in another crucial element, security (Sec), into every stage of the Software Development Life Cycle (SDLC).

Integrating Security into SDLC

Imagine the SDLC as a bustling city, where every building represents a different part of the development process. In traditional models, security is like a gate at the edge of the city, checking for threats as they try to enter. But in the city of DevSecOps, security checkpoints are scattered throughout, from the central square of coding to the outskirts of deployment. In this city, security isn’t an afterthought; it’s a living, breathing part of the urban landscape.

The need for such integration of security into the SDLC arises from the increasing complexity of cyber threats in today’s interconnected world.
