Intrusion Detection System (IDS)ali ngati scout mu netiweki, ntchito yaikulu ndi kupeza khalidwe lolowera ndi kutumiza alamu. Poyang'anira kuchuluka kwa magalimoto pamaneti kapena kachitidwe ka wolandila mu nthawi yeniyeni, imafanizira zoikidwiratu "laibulale ya siginecha yowukira" (monga ma virus odziwika bwino, mawonekedwe owononga owononga) ndi "khalidwe lodziwika bwino" (monga kuchuluka kwanthawi zonse, mawonekedwe otumizira deta), ndipo nthawi yomweyo imayambitsa alamu ndikulemba chipika chatsatanetsatane chikapezeka. Mwachitsanzo, chipangizochi chikayesa kusokoneza mawu achinsinsi a seva, IDS imazindikira njira yolowera iyi, kutumiza mwachangu chidziwitso kwa woyang'anira, ndikusunga umboni wofunikira monga adilesi ya IP yowukira komanso kuchuluka kwa zoyeserera kuti zithandizire kutsata.
Malinga ndi malo otumizira, IDS ikhoza kugawidwa m'magulu awiri. Network IDS (NIDS) imayikidwa pamalo ofunikira a netiweki (mwachitsanzo, zipata, masiwichi) kuti aziyang'anira kuchuluka kwa gawo lonse la netiweki ndikuwona zomwe zidachitika pazida. Mainframe IDS (HIDS) amaikidwa pa seva imodzi kapena terminal, ndipo amayang'ana kwambiri kuyang'anira khalidwe la wolandira wina, monga kusintha mafayilo, kuyambitsa ndondomeko, kukhala ndi doko, ndi zina zotero, zomwe zingathe kujambula molondola kulowetsa kwa chipangizo chimodzi. Pulatifomu yamalonda yapaintaneti idapeza kuyenderera kwa data kudzera mu NIDS - zambiri za ogwiritsa ntchito zidatsitsidwa ndi IP yosadziwika mochulukira. Pambuyo pa chenjezo lanthawi yake, gulu laukadaulo lidatseka chiwopsezocho ndikupewa ngozi zotulutsa deta.

Intrusion Prevention System (IPS)ndiye "woyang'anira" pamanetiweki, zomwe zimawonjezera kuthekera kolimbana ndi ziwopsezo pamaziko a ntchito yodziwika ya IDS. Pamene magalimoto oyipa azindikirika, amatha kuchita zinthu zenizeni zotsekereza, monga kudula maulumikizidwe achilendo, kuponya mapaketi oyipa, kutsekereza ma adilesi a IP ndi zina zotero, osadikirira kulowererapo kwa olamulira. Mwachitsanzo, IPS ikazindikira kutumizidwa kwa imelo yokhala ndi mawonekedwe a virus ya ransomware, imalowetsa imelo nthawi yomweyo kuti kachilomboka zisalowe mu netiweki yamkati. Pamaso pa DDoS kuwukira, imatha kusefa kuchuluka kwa zopempha zabodza ndikuwonetsetsa kuti seva ikugwira ntchito bwino.
Kuthekera kwa chitetezo cha IPS kumadalira "makina oyankha zenizeni zenizeni" ndi "dongosolo lokulitsa mwanzeru". IPS yamakono imasintha nthawi zonse nkhokwe ya siginecha kuti igwirizanitse njira zaposachedwa kwambiri zowukira. Zogulitsa zina zapamwamba zimathandizanso "kusanthula kwamakhalidwe ndi kuphunzira", zomwe zimatha kuzindikira zatsopano komanso zosadziwika bwino (monga zochitika zamasiku a zero). Dongosolo la IPS logwiritsidwa ntchito ndi bungwe lazachuma lidapeza ndikuletsa jekeseni wa SQL pogwiritsa ntchito chiwopsezo chosadziwika pofufuza pafupipafupi zafunso la database, kuletsa kusokoneza deta yayikulu.
Ngakhale IDS ndi IPS zili ndi ntchito zofanana, pali kusiyana kwakukulu: kuchokera ku momwe ntchito ikuyendera, IDS ndi "kungoyang'anira mosasamala + kuchenjeza", ndipo sichimalowerera mwachindunji pamayendedwe apakompyuta. Ndizoyenera pazochitika zomwe zimafunikira kuwunika kwathunthu koma sizikufuna kukhudza ntchitoyo. IPS imayimira "Defence + Intermission" ndipo imatha kuthana ndi ziwopsezo munthawi yeniyeni, koma ikuyenera kuwonetsetsa kuti sikukuganizira molakwika kuchuluka kwa magalimoto abwinobwino (zabodza zitha kuyambitsa kusokonezeka kwa ntchito). Muzochita zenizeni, nthawi zambiri "amathandizana" -- IDS imayang'anira ndikusunga umboni mokwanira kuti awonjezere siginecha ya IPS. IPS imayang'anira kuyang'anira nthawi yeniyeni, kuwopseza chitetezo, kuchepetsa kutayika komwe kumachitika chifukwa cha kuwukira, ndikupanga chitetezo chathunthu chotsekedwa cha "detection-defense-traceability".
IDS/IPS imagwira ntchito yofunikira pazochitika zosiyanasiyana: pamanetiweki apanyumba, kuthekera kosavuta kwa IPS monga kutsekereza komangidwa mu ma routers kumatha kuteteza motsutsana ndi ma doko wamba ndi maulalo oyipa; Mu network yamabizinesi, ndikofunikira kuyika zida zaukadaulo za IDS/IPS kuti muteteze ma seva amkati ndi nkhokwe kuti zisawonongedwe. M'mawonekedwe apakompyuta amtambo, ma IDS/IPS amtundu wamtambo amatha kusintha ma seva amtambo kuti azindikire kuchuluka kwa anthu omwe ali ndi vuto lambiri. Ndi kukonzanso kosalekeza kwa njira zowukira owononga, IDS/IPS ikukulanso molunjika ku "AI intelligent analysis" ndi "multi-dimensional correlation discovery", kupititsa patsogolo kulondola kwa chitetezo komanso kuthamanga kwa chitetezo cha intaneti.
