The Chocolate Sprinkles of InfoSec

Posted by Günter Ollmann on Feb 2, 2016 10:30:33 AM

In the rapidly expanding world of threat intelligence, avalanches of static lists combine with cascades of streaming data to be molded by evermore sophisticated analytics engines the output of which are finally presented in a dazzling array of eye-candy graphs and interactive displays. 

For many of those charged with securing their corporate systems and online presence, the pressure continues to grow for them to figure out some way to incorporate this glitzy wealth of intelligence into tangible and actionable knowledge.

IDS has been around for decades and has long been a cornerstone of network security. But over the years, IDS was gradually absorbed by IPS, and IDS simply became thought of as a deployment option of IPS.

However, this subservient role of IDS in relation to IPS introduces a subtle but important compromise – detection takes a backseat to prevention. Because IPS is deployed in-line with network traffic, performance concerns are paramount. Prevention cannot slow the speed or flow of business, and that meant detections must be near-instantaneous.

The need to block threats within milliseconds locks IDS/IPS into using signatures for detections. While signatures can detect a wide variety of threats, they rely on the fast-pattern-matching of known threats.
