One of the most frightening things about modern cyber-attacks is that a breach can remain undetected within networks for weeks, months or even years. This time gives hackers the luxury of lateral movement within a network, meaning they can acquire better credentials, compromise more systems and search for the most profitable and most damaging information.

And perimeter defense tools are almost worthless once hackers are quietly rampaging behind the lines. But malware has to communicate back to the hackers somehow, and new monitoring tools have emerged that can identify that traffic.

As such, traffic monitoring tools could very well be the next big thing in network security, protecting networks against cyber-attacks and helping even if a breach has already happened.
