Experts Question Perimeter Defense

In a recent article for Science magazine, William Wulf and Anita Jones, both computer science professors at University of Virginia, questioned the effectiveness of the perimeter defense model currently used in most cyber security models. The two professors questioned the method for a number of reasons, including the insider threat, fragility and that it has not worked in the past.

Instead of the perimeter defense, Wulf and Jones argue for looking to the model of the internet for our security solutions. Security should come in a variety of models that would make security readily adaptable to different organizations and systems.

In advocating for multiple systems over one, Wulf and Jones point to the different security needs of different organizations, that future application security needs are impossible to predict and that with a host of security models, cracking one does not compromise the others.
