With the rapid development of information technology, computer networks are exposed to a wide variety of vulnerabilities and an increasing number of security threats. Intrusive traffics affects the normal functionality of the network's operation. Thus, a need for more intelligent and sophisticated security controls such as intrusion detection systems (IDSs) is necessary. Since IDS has to deal with problems such as large network tra c volumes and di culty to realize decision boundaries between normal and abnormal behaviors, classification plays an important role in the detection.
