This multi-part blog series explores how advanced network-traffic analytics changed how the Department of Defense approaches its overall cyber security operations, creating a far more effective methodology for protecting many of our nation’s most sensitive networks.

Today we’ll cover the limitations associated with today’s best, mostly automated tools such as SIEMs, security analytics and perimeter defenses. The problems encountered by the DoD before they began to use advanced network-traffic analytics are identical to the problems enterprises encounter today with securing their own networks.

Perimeter defense tools use a signature-based approach that leaves them vulnerable to even the slightest malware modification, while a legitimate username and password obtained from, say, spear phishing is something that must be let through.
