Machine Learning in Security: 4 Factors to Consider

Key factors to consider before adding machine learning to your security strategy.

Theres a good chance youve considered the implications of machine learning for your security team. As data increases, the skill gap widens, and hackers strategies get more complex, businesses struggle to detect and address cyberattacks.
Machine learning enables behavioral analytics and cognitive security to detonate attachments before they arrive in someones inbox, or correlate types of activity across a network of thousands of users.
The ability to stop attacks before they occur is powerful, but how should security leaders start the process of making their systems smarter with machine learning?
Start With The Basics
Avnet CISO Sean Valcamp advises perfecting your security posture first. Valcamp has been involved with cognitive security in his practice since September 2016, he says.
I caution someone to think they can invest in a cognitive foundation without a strong security strategy in place, he says. Almost immediate gains can be seen in security practices that have a solid foundation.
Since then, hes learned a few other lessons on the still-evolving tech and how it affects employees.
Machine Learning Can Save Time
Overall, the tech landscape has become faster and more consumer-driven, Valcamp explains. People have exponentially more computing power than they once did and generate massive amounts of data.
The importance of timing and accuracy blend together in cognitive security. Information must be legitimized quickly to achieve maximum value from machine learning and stop security threats in any business environment.
The ability to verify and validate accuracy is the biggest value point associated with the cognitive engineer we have, he says.
Machine Learning May Change Staffing & Skills Needs
Security is visibility plus action, says Valcamp. Todays security operators are level-one professionals who primarily focus on visibility and pass information to senior engineers to handle problems they find.
The introduction of machine learning to monitor activity could change the role of junior security engineers. Instead of spending their time watching for breaches, theyll be able to take action.
What we found is, our focus around skill and development of security engineers has moved to more advanced skill sets because the cognitive piece is taking care of the first level, he explains.
This could help companies struggling with the security skill shortage. Cognitive systems can highlight high-risk alerts for senior engineers to tackle, and lower-risk items for junior employees. Ultimately, lower-level employees benefit by building more advanced skill sets.
Machine Learning Wont Automatically Make You More Intelligent
Garbage in, garbage out, says Valcamp. Youre really only as smart as the data presented into the cognitive engineer.
Whatever the smart system is processing, its only valuable if the data is valuable. Businesses behind machine learning platforms need to make sure the information being entered is quality. If not, it increases the risk of fake alerts.
If we track false positives, we feel like were chasing our tail, he explains. We want to make sure weve validated our sources, and are measuring ourselves along the way, so security engineers are spending their time on higher value activities.
