Embodiment Construction

[0039] The present invention will be described in detail below with reference to specific embodiments.

[0040] The present invention is an IDS theoretical modeling method that automatically adjusts the detection mode according to the team leader, and is specifically implemented according to the following steps:

[0041] Step 1, setting the parameters of the IDS;

[0042] The IDS designed by the invention has a detection engine, a rule base and a preprocessor. The detection engine captures network data packets, and performs security detection on the data packets through the rules in the rule base. The preprocessor has the function of identifying multimedia types.

[0043] For non-multimedia packets, the detection engine will detect all the rules corresponding to the communication protocol in the data packet in the rule base. Because this detection method has many detection rules, the detection time is long, but the security is high. This detection method is called conserva...

Abstract

The invention discloses an IDS theoretical modeling method for automatically adjusting a detection mode according to a queue length. The method specifically comprises the following steps: step 1, setting parameters of an IDS; 2, analyzing an IDS state space; 3, calculating the average number of data packets in the IDS, the average number of the data packets to be detected and the average number ofthe data packets being detected; and step 4, calculating average stay time and average queuing waiting time of the data packet in the system. The IDS model established by the method can automaticallyadjust the detection mode of a multimedia packet according to the length of the queue to be detected. According to the invention, the problem of reaction delay caused by the fact that the detection mode of the multimedia packet can only be adjusted according to the packet loss rate in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of information security, and relates to an IDS theoretical modeling method for automatically adjusting the detection mode according to the captain. Background technique [0002] An intrusion detection system (Intrusion Detection System, IDS) is a commonly used network security device, which can use a detection engine to perform security detection on captured network traffic. Among network traffic, multimedia traffic occupies a large proportion. Compared with other types of data packets, data packets carrying multimedia information (hereinafter referred to as multimedia packets) have higher security. Therefore, a separate and simple detection method can be adopted for the multimedia packet. In the prior art, the detection of multimedia packets can only be adjusted according to the packet loss rate, and this detection method will delay the system response. SUMMARY OF THE INVENTION [0003] The purpose of ...
