What is DevSecOps? Why Is It Important for Your Modern IT Infrastructure?

Did you know that DevSecOps is a methodology to the platform and automation that connects with security? In software development, DevSecOps is considered that security is a shared responsibility all through the IT life cycle. It is the philosophy of integrating security practices within the DevOps procedure.  
 
Nowadays, this approach has been shifted from DevOps to DevSecOps. DevOps helps in eliminating the communication gap between different teams to smoothen and fasten the process of code deployment and development is done faster. The process of DevOps involves Continuous Integration and Continuous Delivery. In Continuous Integration, code is always integrated into the development environment and higher environments. While, in Continuous Delivery, the app release is automated to fasten the process and avoid any avoid miscommunication.   

There is automation for DevOps to release code with ease into the higher environment and create release or deployment logs. This also assists app developers to understand the updates done by team members viewing release or deployment log, and so working accordingly. You should know that working code is used to control the process and automate it. This is known as a Policy as Code. Besides, the application infrastructure is managed through codes as infrastructure as code. In this, code management and designing can be done on the same platform.  
 
On the contrary, DevSecOps includes developing a ‘Security as Code’ culture with ongoing, flexible collaboration between release engineers as well as security teams. The DevSecOps movement, like DevOps itself, is focused on creating new solutions for complex software development processes within an agile framework. Its major purpose is to offer a secure process of entire development so that there will not be any technical glitch after the deployment and release of an application.  
 
Both threat modeling and security testing processes are a part of DevSecOps. In these processes, all the pipelines during deployment are tested to save time as well as money. Based on vulnerabilities, testing of the application is done to avoid future mishaps. In terms of security testing, there is automation that helps in testing all new deployments in an automated manner and regularly.  
 
The best thing is that reports can easily be generated if common vulnerabilities occurred often during CI or CD process. DevSecOps never allow security to be compromised. In DevSecOps’s point of view, all the applications must be secured before initialization. This makes the infrastructure more powerful in almost all possible ways. Continuous feedback after each stage of development and code integration is important in the perspective of DevSecOps. Proper warnings for vulnerabilities are provided and alerts to fix the security issues.  

Briefing about DevSecOps, there is no specific term available that can denote it, but still, it differentiates:  
Dev: Development 
Sec: Security 
Ops: Operations 
This means that development, security, and operations should be in continuous competition to attain the desired outcomes.  

Top Reasons why should choose DevSecOps: 

(1) Detect bugs and vulnerabilities at earlier stages and fix them at a lower cost. 

(2) Confidently use open-source packages with an automated tool to track harmful components. 

(3) Save costs on resource management as you are only looking for the tools and approaches that will help design secure software. 

You would need certain steps and toolset to implement DevSecOps. Some of the DevSecOps Steps and Toolset are mentioned below: 

(1) WhiteSource: It helps in scanning all your projects and detecting open-source components, their license, and known vulnerabilities. In addition, it also offers fixes. 
(2) Nessus: It is a network security scanner. It utilizes plug-ins, which are separate files, to handle the vulnerability checks. 
(3) Docker Security: Docker scan allows you to choose the level of vulnerabilities displayed in your scan report using the –severity flag. 
(4) Synk: Find and automatically fix vulnerabilities in your code, open-source dependencies, containers, and infrastructure as code. 

We have organized our second “Coredge TechTalk” program virtually in which one of our DevOps engineers, named Mr. Pruthviraj Sonwane spoke about DevSecOps and covered DevSecOps steps, tools, its requirement, and a lot more.
