Abstract
Despite the variety and number of network security devices and policies available, sensitive data, such as intellectual property and business data, can still be surreptitiously sent via the Internet to unscrupulous receivers. Furthermore, few security mechanisms address securing or limiting covert channels. This study defines a framework for determining a rule set to minimize covert channel capacity on the DNS protocol specifically. The information and techniques used in this study may be useful in aiding security professionals and developers with enforcing security policies on DNS and other Internet protocols.;This research resulted in the development of a rudimentary tool, referred to as NV-DNS, capable of detecting and effectively limiting the capability of covert channels in DNS communication packets.
