DHS Prepares Overhaul of Internal Security Operations

The Homeland Security Department announced future plans to overhaul an organization that defends DHS’ own internal networks.

A counter-hack mechanism called the intrusion defense chain, or "kill chain” -- developed by researchers at Lockheed Martin -- is expected to drive the revamp, according to DHS officials. A kill chain predicts an intruder’s attack plan and breaks it down into steps that must be taken to achieve the ultimate hack -- for instance, obtaining a map of the most critical US water plants from a DHS network. Operators then devise a countermeasure for each action that, if applied along any point in the chain, will thwart the criminal's plan.

The office of DHS Chief Information Security Officer Jeff Eisensmith is requesting security operation ideas, "including most notably the employment of an Intrusion Defense Chain methodology to 'align enterprise defensive capabilities to the specific processes an adversary undertakes to target that enterprise," stated a market research survey. The notice quotes a 2011 Lockheed paper. The potential plans also ask vendors how they would measure the effectiveness of the center, if given the management job. And officials want contractors to list staffing and facilities requirements DHS should consider.
