This article analyses the actual reality of network security and briefly intruduces a few of aggressive measures which threaten the safety of network. From these we can see, the passive ways such as firewall and anti-virus software to combat network attack can not meet the increasingly needs of network accessing .As a result, an intrusion detection system must be established to differentiate between the legal accessing and inbreaking attack. That is intrusion detection.
