A recent SANS Top 20 Threats list indicated that of the top 20 threats enterprise IT security groups should be concerned about, 80% were application-level threats. Further compounding the issue, threats come in more and more flavors, are multi-vector, and resist traditional definitions (e.g., virus, exploit, or worm).
Threats to an organization can take many forms. They can target an application, or can be carried by an application. The traditional defense mechanisms - firewalls and IPS/IDS – cannot effectively control applications, and can't recognize the variety of threats targeting the applications anyway – since IPS/IDS only look at threats formally defined as "exploits". |
