An Introduction to DevSecOps for Beginners

In this article, I will talk about a buzzword in the DevOps domain – DevSecOps.

DevOps has been a success in the past few years. It has now become one of the core practices in every organization. Bringing collaboration between development and operation teams has helped organizations launch their products at speed with higher quality.

By using DevOps tools and practices, most of the things have got smoother and automated.

But do you think there is no challenge with DevOps?

There is!

Why do we need DevSecOps?

Forrester research showed that 58% of companies had a data breach, and 41% of those come from software vulnerabilities. Security mistakes have the potential to cause considerable harm and cost organizations in millions.

Earlier in the waterfall model, you used to gather all the requirements, work on all the requirements, and then after months or years, you used to deliver the complete product. In DevOps, the complete product is released iteratively. An application can have hundreds of iteration in a day, but would a penetration tester be able to find security flaws in an application a hundred times a day?

The answer is No!

Developers, admins, architects think if they are working on the cloud, they are safe because the cloud provider is taking care of the security. This is a myth and not true. Most of the time, if you are working on the cloud, you are more exposed to attacks.

So in today’s time, security is a very important factor in every company. Traditional security is not good enough to keep up with the rapid pace of DevOps.

This is where DevSecOps comes to rescue!

What is DevSecOps?

DevSecOps is security as a code culture where you integrate security tools in the DevOps lifecycle. Security as a part of the DevOps process is the only way to mitigate the risks.

It is a transformational shift that incorporates security culture, practices, and tools in each phase of the DevOps processes. It removes the silos between development, security, and operations team.


It follows the shift-left approach, which means injecting security processes early into the design/plan stage to provide security awareness to development and operations teams and fulfill the cybersecurity requirements.

These are the practices of how DevSecOps is being implemented:

Modern technology innovation plays a vital role in DevSecOps. Security as a code, Compliance as a code, and Infrastructure as a code can eliminate many manual security activities and boost the overall efficiency.

Tools for DevSecOps

It requires many technology stacks with several solutions that need to be carefully integrated to deploy the DevSecOps culture without creating gaps or creating bottlenecks in security.

Below are some important and trending DevSecOps tools:

This is the flow of different phases in the DevSecOps ecosystem. Here security scanning will be a part of the complete ecosystem.
