Abstract

The invention provides a detection method and device for a CC (Challenge Collapsar) attack and relates to the technical field of network information security. The method comprises the steps of calculating a first prior probability of normal access traffic of a Web page and a second prior probability of CC attack access traffic of the Web page; obtaining a ratio of the normal access traffic and the ratio of the CC attack access traffic, wherein the ratio of the normal access traffic and the ratio of the CC attack access traffic are determined based on sample data; through adoption of a first posterior probability mode, calculating a first posterior probability of the normal access traffic based on the first prior probability and the ratio of the normal access traffic; through adoption of a second posterior probability mode, calculating a second posterior probability of the CC attack access traffic based on the second prior probability and the ratio of the CC attack access traffic; and determining whether the Web page bears the CC attack or not based on the first posterior probability and the second posterior probability. The technical problem that in the prior art, the CC attack cannot be detected timely, effectively and accurately is mitigated.

Description

technical field [0001] The invention relates to the technical field of network information security, in particular to a CC attack detection method and device. Background technique [0002] With the continuous development of Internet technology, computer network technology has been widely used in all walks of life. The rapid development of Internet applications has brought many security vulnerabilities. These loopholes will expose computers to virus and hacker attacks, which may lead to data loss, and may seriously lead to loss of user data or property damage. Therefore, the protection of Internet security is the focus of Internet technology. [0003] The full name of CC is Challenge Collapsar, which means "challenge black hole". CC attack is a kind of DDOS distributed denial of service. CC attack uses continuous connection requests to websites to cause denial of service, and CC attack has a certain degree of concealment. [0004] The current CC attack detection and defen...
