Protecting computing infrastructure is an expensive but necessary task. Companies that run their own computing infrastructure need to be constantly vigilant against intruders on their networks and groups or individuals that seek to intercept their communications.

Companies turn to firewall and intrusion detection system vendors to help them safeguard their information and infrastructure. These companies are putting their faith in expensive devices that attempt to distinguish between friendly and malicious traffic.
Despite the expense and complexity of these systems, malicious users seem to find ways to avoid detection and news of massive breaches have become an almost daily occurrence. We propose to fundamentally change the way to look at information security. We highlight some of the fundamental flaws in current systems and expose risks that many experts know, but do not adequately take into consideration.
