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 Should Sprint

Security teams traditionally used to set up for the annual penetration test, followed by a post-mortem, plans, reviews, and finally changes to tools and tactics. When attackers were on a fairly relaxed schedule, this was a great plan. It allowed for careful consideration of every change, input from everyone concerned, and rigorous testing before any deployment. It was also glacial in its pace. Today, the glaciers are retreating and so should the plan to change security once every 12 months or so.

Sprints used by software developers allow for tightly defined, small-scope changes at a rapid pace. With a defined goal and defined duration (which can be from a day to a couple of weeks), sprints can offer security teams a discipline to respond to single CVEs, new attack techniques, or revisions to malware.

The great lesson of the sprint is that every change doesn't have to deal with every issue. Allowing team members to focus on a single issue at a time and deal with it well means that over the course of a month, a quarter, or a year, many security holes are patched without any of them having to wait for a lengthy update and review cycle.

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.

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.
