The tech industry is just doing fine with DevOps. IT professionals use automation, Continuous Integration and Continuous Development (CI/CD) to shorten the software development lifecycle. This process has benefitted the industry in the following ways:

• Revved up the process of software development 
• Increased collaboration between Development (Dev) and Operations (Ops) 
• Incorporated automation in the software development lifecycle (SDLC)

But you know what is missing? Security.

With millions of security breaches increasing worldwide every day, there is a serious need to incorporate security practices in the software development process. 

Introducing DevSecOps, a fresh approach to software development that considers security while practicing DevOps. This means that if a software development team is working on developing software, it is ensured that security is incorporated right into the code while creating it.

This blog introduces you to DevSecOps, how it is different from DevOps and the various DevSecOps tools currently used in the industry.

Let’s get started.

What is DevOps?

DevOps is a means of establishing a seamless bridge between development and operations teams for the betterment of communication as well as productivity. Before the entry of DevOps, it was difficult for the software development and operations teams to collaborate with each other. It was right when DevOps entered and decreased the timeline of the software development lifecycle.

Again, the key point here is to speed up the development cycle with the delivery of high-quality software at a faster pace.

Technology Focus: 

Automation, Continuous Integration and Continuous Delivery (CI/CD): It focuses on the efficiency through automation in integrating and continuously delivering processes.

Example:

Now imagine the same team developing a website. Under DevOps, the developers write code and work closely together to deploy the site as soon as possible. They will work on tools that automatically test and release updates on the website without delay.

What is DevSecOps?

On the other hand, DevSecOps is the new approach. It adds security into the collaboration of software development and operations. It takes security as the backbone of the complete software development and delivery process, and considers it at every stage of the software development lifecycle.

Technology Focus: 

DevSecOps emphasizes building security into the development code right from the start rather than adding it later on. Therefore, it considers security as the backbone of the SDLC.

Example:

Once again, let’s use the same example of a website. In DevSecOps, security is involved the whole way through, much like the operations teams do their part while developers code and operations teams are deploying. 

They check for vulnerabilities in the code and ensure security tools are integrated within CI/CD pipelines, while continually conducting their security assessments. This way, security measurements are built-in, rather than being something done after.

Note: 

• DevOps simply accelerates delivery through efficient collaboration between development and operations. 
• DevSecOps makes it possible to add the security dimension to that collaboration and get the software with safety integrated from the very start.

This makes DevSecOps a much more holistic approach in the current context of common security threats.

DevOps vs DevSecOps: Which is the Better Career Choice?

As the need for quick software delivery in organizations is at its peak, career paths in software development and operations have gained significant traction. Among these, DevOps and DevSecOps stand out as popular choices. While both aim to enhance collaboration between development and operations teams, they differ in their approach to security. 

Let’s explore the key differences and help you decide which path might be better for you.
