ITOps vs. SecOps vs. DevOps vs. DevSecOps

ITOps, SecOps, and DevOps may sound similar. Indeed, they are similar — to a degree. But they have different areas of focus, different histories, and different operational paradigms.

Keep reading for an overview of what ITOps, SecOps, and DevOps mean and how they compare. We’ll also explain where DevSecOps fits into the conversation — and why you shouldn’t worry so much about defining these terms perfectly as you should about finding ways to operationalize collaboration between your various teams.

SecOps vs. ITOps

SecOps is what you get when you combine security teams with IT operations teams, or ITOps. Put another way, it’s the integration of security into IT operations.

Traditionally, most organizations have maintained both ITOps and security teams. The ITOps team’s responsibility is to manage core IT processes — like provisioning infrastructure, deploying applications and responding to performance issues. The security team, meanwhile, specializes in identifying and responding to security risks.

In the past, security and IT operations did not work in tandem. They pursued their various responsibilities in isolation from each other.

SecOps changes that. The big idea behind SecOps is that it combines security with IT operations in a way that maximizes collaboration.

This isn’t to say that ITOps teams are totally incapable of managing security without a SecOps mindset. Any decent IT team has always done its best to secure the environments it manages, to the best of its ability. But ITOps engineers never specialize in security. The task of identifying and responding to security problems fell to a separate team of security professionals.

With SecOps, the security team works more closely with the IT team, and vice versa. When done well, SecOps ensures that security is an active priority across all day-to-day IT operations rather than something that is managed separately.

To be clear, SecOps doesn’t mean turning your security and ITOps teams into a single, combined team. The teams remain separate; they just work more closely together.

ITOps vs. DevOps

DevOps is a collaboration between developers and IT operations teams.

Like SecOps, DevOps was conceived to address inefficiencies associated with isolation between teams. The goal of DevOps is to ensure that developers understand the needs of ITOps when they write software, and that IT operations teams understand what developers intend for software to do when they manage it.

Also like SecOps, DevOps doesn’t erase independent development and ITOps. Some organizations may choose to create a new DevOps team alongside these two other teams, while others “do” DevOps simply by finding ways for developers and IT engineers to work more closely together. Either way, though, businesses still typically keep their development and IT operations teams.

SecOps vs. DevOps

SecOps and DevOps share key high-level similarities:

  • Their main goal is to improve collaboration between teams that would otherwise operate independently.
  • They tend to encourage automation and real-time communication in an effort to foster collaboration.
  • They increase the efficiency and scalability of complex operations.
  • They represent philosophies or goals more than specific operational frameworks. In other words, there is no specific recipe to follow or tool to use in order to enable either SecOps or DevOps. It’s up to organizations to decide how to operationalize both concepts.

The big difference between the two concepts is the specific teams involved. As we’ve noted, SecOps brings together security teams and ITOpsteams, while DevOps focuses on collaboration between developers and ITOps.

So, IT operations is a part of both equations, but SecOps and DevOps are otherwise different.

What about DevSecOps?

It’s hard to talk about ITOps, SecOps, and DevOps without also mentioning DevSecOps, also known as SecDevOps, a concept that brings all the teams we’ve talked about so far — development, security, and IT operations — together into a collaborative model.

You can find different definitions of DevSecOps out there. Some treat it as the result of combining DevOps with SecOps. Others imply that the distinction lies in how much your DevSecOps program focuses on development as opposed to IT operations.

Arguably, it’s not worth fixating on the nuanced differences between DevOps, SecOps, and DevSecOps. In a world where most businesses have already embraced DevOps, SecOps arguably implies DevSecOps — because if your developers are collaborating with your IT operations team, then you’ll naturally end up with security, development, and IT operations working together when you embrace SecOps. You can mince words if you want, but at the end of the day, any business that cares about security, IT operations, and also cares about DevOps is going to be a DevSecOps business.

Collaboration Is the Key

Rather than getting hung up on semantics, a healthier takeaway from the conversation about ITOps, SecOps, DevOps, and DevSecOps is that no matter which definitions you choose to use, the ultimate lesson is that collaboration is the foundation for everything.

And we’re not talking here about collaboration in principle. What really matters is the ability to ensure that all stakeholders — developers, IT engineers, security engineers, and anyone else who plays a role in software delivery — has access to the tools and data necessary to integrate security into all aspects of the software delivery process. That only happens when security becomes the responsibility of everyone, not just a specialized team of cybersecurity experts.

Whether you want to approach integrated ITOps through SecOps, DevOps, DevSecOps, or all three, your goal should be to find ways to achieve meaningful collaboration between your various teams. Don’t just think in abstract terms; think about what it means on a day-to-day basis to ensure that each team understands and can help support the goals of other teams rather than existing on its own island.
