Current misuse detection systems are of little use for new attacks and they cannot automatically update their rule databases.SRRW

CHGL and the technology of co-training for independent dual-model greatly improve the apperception ability of CLMDS

and provide a good solution for the limitation of misuse detection systems.Apperception ability is analyzed from static aspect as well as dynamic aspect.Results of the experiments show that with powerful apperception ability CLMDS can not only detect new attacks but also update its own rule base automatically.
