DevOps vs. DevSecOps: What you need to know

Posted on 27th May 2022 by FinXL

DevOps is a software development methodology focused on bringing together members of two departments: IT operations and software development.

The concept of DevOps is nothing new. According to Atlassian, the phrase started appearing around 2007, following the rise of the Agile method (with the Agile Manifesto being published in 2001). Though Agile was considered by many to be an improvement on older software development models, others argued that it still allowed for too much silo’ing, and not enough cooperation.

In more recent years, industry professionals have started implementing a new concept: DevSecOps, a methodology that includes security testing throughout the traditional DevOps continuous delivery process.

If you’re looking to develop new software, or hoping to refine your software development process, this article will explain DevOps and DevSecOps, and help you decide if they’re the right methodologies for you.

 

DevOps: An overview

Before we can dive into the more nuanced concept of DevSecOps, let’s first break down exactly what DevOps is.

The main goal of DevOps is to make it easy for IT operations experts and software developers to work in tandem throughout a project, rather than only checking in when the project is nearing completion.

This not only ensures that the final product has a better outcome, but it also makes the process of developing and releasing software faster and more reliable.

Within the DevOps Lifecycle, there are generally four different phases that happen in a continuous loop:

 

Plan. When IT teams and software developers map out the features and capabilities of the software they’re creating, and develop a general strategy for testing, development, and delivery.

 

Develop. This is the process of actually creating the software—writing code, testing it, reviewing it, and refining it as needed.

 

Deliver. Once the software is developed, both IT teams and the software developers will work on delivery—going through final approvals and deploying the software into a production environment.

 

Operate. Once a project has been delivered, the teams will continue monitoring it and assisting with troubleshooting, adoption, and further development as needed.

 

There is more to DevOps than simply the process—DevOps is a philosophy, and also includes specific tools and techniques for software development.

 

Continuous workflow. Unlike other processes that have a start and end period, DevOps is a continuous cycle, involving continuous feedback, monitoring, development, and delivery.

 

Speed and agility. A big part of DevOps is about making the process of developing and releasing software faster, more efficient, and more adaptable. This is achievable thanks to automation tools, improved collaboration, and shorter cycle times.

 

Visibility and collaboration. Above all else, DevOps is about improving visibility and transparency between teams, and encouraging collaboration for better results.

 

What is DevSecOps?

DevSecOps is an offshoot of DevOps that puts a greater emphasis on security throughout the process. DevSecOps rose out of criticisms of the traditional DevOps processes, which many felt lacked when it came to improving security without slowing down the software delivery timeline.

In response to this issue, some businesses started including the Security teams in the software development process, rather than only calling them in at the end of a cycle for final checks.

For example, in a DevSecOps operation, the security team will contribute to the planning phase by suggesting when security testing will be most needed. They’ll run automated security tests throughout the process, and will provide context and guidance to ensure software is as secure as possible before going live.

 

Bringing DevSecOps to your organisation

If you’re working in the tech industry and looking for the best methods for developing software, then it may be time to consider DevOps or DevSecOps. But a word of warning: these processes are complicated, and can take time to roll out.

There is another option, however. You can outsource software development to a skilled team that has experience working with DevOps or DevSecOps. This is a solution we offer to our many clients here at FinXL.
