Applying sigmoid filter for detecting the low-rate denial of service attacks

This paper focuses on optimizing the sigmoid filter for detecting Low-Rate DoS attacks. Though sigmoid filter could help for detecting the attacker, it could severely affect the network efficiency. Unlike high rate attacks, Low-Rate DoS attacks such as “Shrew” and “New Shrew” are hard to detect. Attackers choose a malicious low-rate bandwidth to exploit the… CONTINUE READING
