摘要： A method and apparatus for storing an intrusion rule are provided. The method stores a new intrusion rule in an intrusion detection system having already stored intrusion rules, and includes: generating combinations of divisions capable of dividing the new intrusion rule into a plurality of partial intrusion rules; calculating the frequency of hash value collisions between each of the generated division combinations and the already stored intrusion rules; dividing the new intrusion rule according to the division combination which has the lowest calculated frequency of hash value collisions; and storing the divided new intrusion rule in a corresponding position of the intrusion detection system. According to the method and apparatus, the size of the storage unit occupied by the intrusion rule can be reduced, and by performing pattern matching, the performance of the intrusion detection system can be enhanced.

摘要： A method of storing a pattern matching policy and a method of controlling an alert message are provided. The method includes (a) generating a content structure as a sub-structure of a header combination structure of a stored traffic pattern which is a policy to be newly applied to a pattern matching apparatus; (b) determining whether a content of the stored traffic pattern is identical to a content of an original traffic pattern stored in advance in the pattern matching apparatus; (c) allocating a content index of the content of the original traffic pattern to the content of the stored traffic pattern if the content of the stored traffic pattern is identical to the content of the original traffic pattern; and (d) determining whether a header combination structure of the original traffic pattern comprises only one content structure or more than one content structure and allocating a header index of the header combination structure of the stored traffic pattern to the header combination structure of the original traffic pattern if the header combination structure of the original traffic pattern is found to comprise only one content structure. Accordingly, it is possible to efficiently use hardware memories with limited storage capacities and effectively perform a pattern matching function.

摘要： A real-time stateful packet inspection method and apparatus is provided, which uses a session table processing method that can efficiently generate state information. In the apparatus, a session table stores session data of a packet received from an external network. A hash key generator hashes a parameter extracted from the received packet and generates a hash pointer of the session table corresponding to the packet. A session detection module searches the session table for a session corresponding to the received packet. A session management module performs management of the session table such as addition, deletion, and change of sessions of the session table. A packet inspection module generates state information corresponding to the received packet from both directionality information of the packet and entry header information of the packet stored in the session table and then inspects the packet based on the generated state information.
