This year at RSA 2017, we caught up with VP Cloud Research Mark Nunnikhoven to get his insights on trends and challenges the modern security team is facing and the steps we can take towards a more secure and layered approach to hybrid cloud security. Whether you’re moving to cloud, your DevOps team is feeling the pressure of security responsibilities, or you can’t determine if the latest “silver bullet” solution is what you really need, Mark provides the answers to your burning security questions.

Here are some great takeaways from the interview to help you answer your hybrid cloud security questions.

More and more we see DevOps teams feeling overwhelmed by the challenges of increasing responsibilities with fewer resources. What can your security vendor do to help balance the load?

There is currently an overload in messaging from all vendors, but you have to can’t rely on one thing and have to look to your security best practices. Advanced techniques like machine learning can help, but if you can catch a problem with a simple check of what’s known good or known bad, why wouldn’t you go for the simpler solution?

“Machine learning” is the newest fad in security, but the definition isn’t always so clear. How do you define machine learning and what is it doing to improve security?

It’s a big buzzword right now in security, but it isn’t even a new tool to Trend. Machine learning, to the IEEE Computational Society and tech communities, is clearly defined. The simple result is setting up a computer program that will be able to look at something and make a decision whether it matches a known set of something or not. Over time the model learns and will be able to make judgements based on its learnings.

With that understanding of machine learning, it’s easy to understand why others might consider it to be the be-all end-all solution. Why might it not be enough?

Nothing is perfect. Even the best trained machine learning models are only in the high 90’s for accuracy. You can’t expect there to be a one-trick pony solution for security. When responsible for a customer’s data, you can’t responsibly protect it with one tool. People have made those controls, people make mistakes.

You’ve been hit with ransomware. What are the steps you should take in the first 24 hours?

It depends what level of user you are. Hopefully you’ve take the steps to back up your data and apply basic security controls. While it’s hard to give generic advice, if you have been breached, the easiest thing you can do is disconnect your system from the network, but leave it on. Once you’ve disconnected, you prevent further damage, but if you turn it off, you can actually increase the damage. Then get in touch with an expert, IT help desk, consulting companies, or service providers. But leave it as is! This gives a better chance of recovering your data. This is a nightmare scenario. Ideally it is better to take the preventative measures up front.

Many teams are making the move to a hybrid cloud environment. What can security vendors be doing to help with that move and make the transition easier?

What people need to realize up front, it’s not a spontaneous move, it’s a transition that applies to both security and operations. Look at where you want to be in the cloud and your ideal end state, and the tools needed to make that change and start applying those changes today in your data center. The faster you can get your teams used to those new tools and skill set as you migrate your assets out to the cloud, the smoother transition you will have.
