To dissolve the present deficiencies of fast matching for massive data and adaptability of attack type in intrusion detec-tion system,a distributed intrusion detection systems based on counting bloom filter (CBF)was designed and implemented.Af-ter a brief introduction of the principle of CBF,the design method of the matching engine based on CBF technology and mecha-nism of the whole system were explained.The system leveraged CBF to carry out fast matching,and could modify the parame-ters and matching rules of CBF to suit new attack types quickly.The results of the experiment showed that its performance and adaptability had been improved greatly.
