ABSTRACT:
A method of updating intrusion detection rules through a link data packet is used to dynamically update rules storages of Snort system hosts. Firstly, an update sponsor in the network transmits a link data packet with an intrusion detection rule to the Snort system host. The Snort system host acquires the intrusion detection rule from the received link data packet, and parses an operation type of the intrusion detection rule. Then, the Snort system host verifies the validity of the intrusion detection rule. Subsequently, the rules storage is updated according to the type of the valid intrusion detection rule and a rules tree.
