It has been possible to build 100 % digital , network - based systems for security , surveillance and remote monitoring for some time 在某個(gè)時(shí)候建成一個(gè)百分之百的數(shù)字式的基于網(wǎng)絡(luò)系統(tǒng)的安防系統(tǒng)以及可以進(jìn)行遠(yuǎn)程的訪問,這也是有可能的。
By the detecting technique utilized , intrusion detection systems can be classified as misuse detection systems and anomaly detection systems ; according to the source of data , intrusion detection systems can be grouped into host - based and network - based systems 從所采用的技術(shù)看,入侵檢測系統(tǒng)大致可分為誤用檢測和異常檢測兩大類;從檢測數(shù)據(jù)的來源看,又可分為基于主機(jī)的和基于網(wǎng)絡(luò)的兩種。
