Cisco's Self-Defending Network is a difficult concept to explain. The challenge was to find an engaging way to present the new technology, as compared to previous security solutions which were more labour-intensive. A creative approach was to create an analogy with video games. The banner has a challenging 'destroy the worm' game which is quite challenging, conveying the difficulty of self-administered security systems. Then, when it's Cisco's turn, the game plays automatically and the problem is quickly alleviated and the level cleared to convey the simplicity and effectiveness of the Self-Defending Network.
