Why not just have DevOps without the Sec?

If you don’t include security testing, risk assessments, compliance evaluations as part of the entire software delivery or release pipeline, you’re putting your organizations at risk. It goes beyond just failed release or delay in getting a feature out in the market, you’ll be introducing vulnerabilities into production, bypassing compliance and failing audit tests. All of these instances of security negligence could have penalties and fines associated with them. 

Security in DevOps is a part of the natural evolution DevOps

DevOps is not a technology but a cultural organization shift that organizations need to make. If we break down DevOps, it comes down to developers and IT operations. What is in the name? DevOps, if we look down at the history, it all started with developers, as in agile, breaking down codes into smaller components. Then they moved around on to the next constraint, “How can we deploy faster”. So we got really good at infrastructure as code and at deploying to not just our private cloud but our public clouds as well. The third constraint was testing. So we started to introduce automation testing into the release process, which evolved into continuous testing as we started shifting testing earlier in the release process.

Security is a constraint if you think otherwise

As I said, it is a natural evolution, now we are in rendezvous with the fourth constraint—security. However, this constraint is not going very well with existing DevOps practices of continuous integration and delivery. To fix the things, it might take renaming DevOps to DevSecOps. DevOps are fine with it because security has always been the last step in that release process and security teams really don’t step in until the code is ready to move into production. I mean in terms of DevOps, a delay in release process of months even weeks is synonymous to blasphemy. Introducing security to DevOps is not as simple as we introduced testing to it. The notion “you move security ‘left’ and things will go right” will not work outright. It requires a change in mindset at organizational level of getting security to work with developers. It requires us to reevaluate and come up with better technology to be able to introduce security into our existing DevOps pipelines. 

Security is boring but ‘right’

Security people have traditionally been tool operators. Some security people might do scripting but there’s a wide disassociation with software engineering group. Developers tend to criticize security people. For them, it is easy to break something than it is to build it. As companies are getting velocity and everyone’s a software company, they’re all building things faster quicker and security is last in the pipeline because it doesn’t inherently provide any business value other than risk reduction. Therefore, the security was left behind not just because DevOps was moving delivery pipelines too fast for security to catchup, but security teams took DevOps as something of a trend in line with agile. 

Eventually, it comes down to business value

Ultimately, security became a part of DevOps after organizations recognized it was a legitimate movement and provides business value. We finally realize that’s conveying and communicating risk reduction must be done at every part of the pipeline whatever your software development cycle looks like. From waterfall to continuous integration whatever you have in place, putting security in that as part of it whether it’s in name of the title or how we talk about it. I think that’s more of a sort of gimmick. Really, those cultures can come from works but just sliding security in DevOps is a start but there’s a lot behind that.

Modern DevSecOps schemes are about the right approach

The fundamentals of the modern DevSecOps schemes rely both on processes as well as the automation of DevSecOps. By processes I mean that there’s a big gap today between the security teams and the development teams in a DevOps process. To be frank, developers don’t really like fixing security issues. Eventually, the security teams take on the issues, and raise an alert but when it comes to communicating these issues and remediating them, they need the cooperation of the development teams. When they have a DevSecOps team that promotes collaboration, they understand how developers think and work, and automate the whole process. That’s the key to a successful relationship between the security teams and the development teams. 

If you look at number of people in those teams you will find hundreds or thousands of developers, probably a dozen or so DevOps people, and a couple of security people. In a nutshell, there is no workaround to introduce security into DevOps. You must automate and have the right tools in place to communicate and close the loops on resolving application security issues. 

There are two approaches to introduce security into DevOps. Security teams would put developers into security teams and teach themselves how developers work and want to see security issues communicated to them and resolved. 

Another approach is to put security analysts into dev teams in order to help developers improve the way they think about security and the way they develop their application. Regardless the approach, that’s something that resolves the gaps that hold automation and the communications by fixing friction between the dev and security team.

DevSecOps is a mindset afterall that closely follows your culture

The purpose and intent of the word “DevSecOps” is a sort of mindset that an agile team is responsible for all aspects from design and development to operations and security. This achieves speed and scale without sacrificing the safety of the code. Traditionally, system is designed and implemented and before release the defects are determined by security staff. With agile practices, it is important to inject security and operational details as early as possible in the development cycle. 

“DevOps is the practice of operations and development engineers participating together in the entire service lifecycle, from design through the development process to production support.

“DevOps is also characterized by operation staff using many of the same techniques as developers use for their system works.
