Cyber space is like a society. Attacking events happen all the time. No matter what is in the cyber space. We need to do many things to defend our computers and network devices
form attackers, for example: update patches, install anti-virus software, firewalls and intrusion detection system. In all kinds of network attacks, it is hard to detect that an attacker install a backdoor after he crack the system. He can do many things by the backdoor, like steal sensitive or secret information. Otherwise, intrusion detection systems are responsible for early warnings, but they usually need to capture all the network packets include the headers and contents to analyze. It costs many overheads for the system. The goal of our research is to detect backdoors correctly, and we only use the network packet headers to analyze.
