摘要: The embodiment of the invention discloses an attack detection method and system. comprises following steps: establishing a plurality models related to HTTP request in advance, detecting each record after web access logs are decomposed by utilizing model respectively obtain parameter abnormal value aiming at record; calculating optimized weighted corresponding model, carrying out calculation final value, determining threshold; judging whether calculated log be detected is greater than determined if yes, as behavior. By applying invention, unknown attacks can actively discovered, so that rate improved; weighting multiple adopted for detecting, limitation single avoided, false-reporting under-reporting conditions reduced, false lowered.
