6 Lessons IT Security Can Learn From DevOps

DevOps has taken over enterprise software development. The discipline has lessons for IT security -- here are a quick half-dozen.

Security is Software
What does it mean to treat everything like software? In the context of DevOps and security, it can help if you think about IT security and modern methods of software development. Break it down, and it makes much more sense.
Modern software development (and by extension, modern software) is the product of many different modules, libraries, and components brought together to make a meaningful whole. The author of any particular component is much less important than whether the component is suitable for the task at hand, reliable, and properly vetted for compatibility and safety. This means that security can be built from 'best of breed' components that assemble through APIs and standard protocols, deployed in the configuration that makes the most sense for the organization. And those aren't the only benefits.
Perhaps the most important characteristic of security as software is that when a single component changes in order to meet the changing threat landscape it can be updated without requiring a wholesale change to the security infrastructure. Just as some cloud applications now see multiple versions shipped each day, a software-modeled security infrastructure can change as rapidly as threat actors require, without the danger of reconfiguring and restarting the entire security stack.

IT Folk Hate Jumping From Level to Level
I agree with a305587. If a person was reading a newspaper and had to continually jump from one page to another (i.e. clicking), that person would read another source.  I think this jumping removes the smooth delivery and dilutes the impact.

Suggestion for improvement?
I'm loving a lot of the articles on DarkReading and want to share them, like this one. We use DevOps and it's relevant. Bummer it's in a click-baity slideshow format. Serious IT professionals won't share these, it's not Facebook.

If you guys get away from these you will have a greater opportunity to grow your reader base. I love the content, not how you're delivering it.
