Embed simple, open, and automated security
Botnets, cryptojacking, and good old fashioned ransomware. These are the things that can keep IT personnel awake at night. And as cyberthreats against government grow, your connected roadways approach must be prepared for them.
So consider a holistic end-to-end security approach, one that can detect and defend against increasingly sophisticated adversaries and the wide array of weapons they use.
Also, be sure to deploy a 24/7 approach that enables deeper visibility and that leverages behavioral analytics and machine learning. But keep it simple to reduce complexity of management, and open to increase integration. Also be sure to seek any and every opportunity to automate security functions. This will speed detection and mitigation, and help your budget.
