摘要: This paper presents a mechanism for detecting and containing fast scanning computer network worms. The countermeasure mechanism, termed NEDAC, uses behavioural detection technique that observes the absence of DNS resolution in newly initiated outgoing connections. Upon abnormal behaviour by host, based on resolution, system then invokes data link containment to block traffic from host. concept has been demonstrated using developed prototype tested virtualised environment. An empirical analysis worm propagation conducted characteristics reported contemporary vulnerabilities test capabilities mechanism. results show is sensitive blocking infection at an early stage.
