Denial of Service
An adversary can evade detection by disabling or overwhelming the IDS. This can be accomplished by exploiting a bug in the IDS, using up computational resources on the IDS, or deliberately triggering a large number of alerts to disguise the actual attack. The tools 'stick' and 'snot' were designed to generate a large number of IDS alerts by sending attack signatures across the network, but will not trigger alerts in IDSs that maintain application protocol context.

Famous quotes containing the words denial of, denial and/or service:
“... that’s what living happens to be ... the physiological denial of reverence and good manners and Christianity.... At your age one’s quite old enough to know what the essence of life really is. Shamelessness, that’s all; pure shamelessness.”
—Aldous Huxley (1894–1963)
“The line that I am urging as today’s conventional wisdom is not a denial of consciousness. It is often called, with more reason, a repudiation of mind. It is indeed a repudiation of mind as a second substance, over and above body. It can be described less harshly as an identification of mind with some of the faculties, states, and activities of the body. Mental states and events are a special subclass of the states and events of the human or animal body.”
—Willard Van Orman Quine (b. 1908)
“The masochist: “I send my tormentor hurrying hither and thither in the service of my suffering and desire.””
—Mason Cooley (b. 1927)
