There was a time when many computer professionals relied solely on one technology to protect their computers and networks. But today, most well-developed organizations use a collection of several technologies, methodologies, and products, each protecting against a particular threat. The concept of a layered protection strategy -- or defense in depth -- is fairly well known. But many IT professionals overlook what can be one of the strongest layers of defense available -- application whitelisting.
No single technology guarantees security, however application whitelisting covers situations not addressed by firewalls or anti-virus utilities. This paper focuses on how application whitelisting can be effectively used as an important layer in your security scenario. It examines other security layers as well, and demonstrates how whitelisting compliments and augments existing defenses. Along the way, well examine the limitations and difficulties inherent in various existing defenses.
Read this whitepaper to learn how to increase your overall security with application whitelisting.
