Sisitimu Yekuona Kupindira (IDS)Zvakafanana nesoutsi iri munetwork, basa guru nderekutsvaga maitiro ekupinda uye kutumira alarm. Nekutarisa traffic yenetwork kana maitiro ehost munguva chaiyo, inoenzanisa "raibhurari yekurwisa siginecha" yakatarwa (senge kodhi inozivikanwa yehutachiona, patani yekurwisa yehacker) ne "baseline yemaitiro akajairwa" (senge frequency yekuwana yakajairika, fomati yekutumira data), uye inokonzeresa alarm pakarepo uye inorekodha log yakadzama kana chimwe chinhu chisina kujairika chawanikwa. Semuenzaniso, kana mudziyo uchiedza kupwanya password yeserver kakawanda, IDS ichaona iyi pateni isina kujairika yekupinda, nekukurumidza kutumira ruzivo rweyambiro kumutungamiriri, uye kuchengetedza humbowo hwakakosha senge kero yeIP yekurwisa uye huwandu hwekuedza kupa rutsigiro rwekutevera kunotevera.
Zvichienderana nenzvimbo yekuiswa, IDS inogona kukamurwa kuita mapoka maviri. Network IDS (NIDS) dzinoiswa panzvimbo dzinoshandiswa key nodes dzenetwork (semuenzaniso, magedhi, maswichi) kuti dzitarise traffic ye network yese uye kuona maitiro ekurwiswa kwe cross-device. Mainframe IDS (HIDS) inoiswa pane imwe server kana terminal, uye inotarisa pakutarisa maitiro ehost chaiyo, senge kugadzirisa mafaira, kutanga kweprocess, kugara kweport, nezvimwewo, izvo zvinogona kubata nemazvo kupinda kwemudziyo mumwe chete. Puratifomu ye e-commerce yakambowana data risingawanzo famba kuburikidza neNIDS -- ruzivo rwakawanda rwevashandisi rwaitorwa ne IP isingazivikanwe yakawanda. Mushure meyevero yenguva yakakodzera, timu yehunyanzvi yakakurumidza kuvharira dambudziko iri uye kudzivirira tsaona dzekubuda kwedata.

Sisitimu yekudzivirira kupinda (IPS)ndiyo "muchengeti" munetwork, iyo inowedzera kugona kwekudzivirira kurwiswa zvichibva pabasa rekuona reIDS. Kana traffic yakaipa yaonekwa, inogona kuita mabasa ekudzivirira panguva chaiyo, akadai sekucheka kubatana kusingawanzoitiki, kudonhedza mapaketi ane njodzi, kuvharira ma IP address ekurwisa nezvimwewo, pasina kumirira kupindira kwemutongi. Semuenzaniso, kana IPS ikaona kutumirwa kwe email attachment ine hunhu hwe ransomware virus, inovhara email nekukurumidza kudzivirira hutachiona kuti husapinde mu internal network. Pakurwiswa kweDDoS, inogona kusefa nhamba yakawanda yezvikumbiro zvenhema uye kuona kuti server inoshanda zvakanaka.
Kugona kweIPS kudzivirira kunoenderana ne "real-time response mechanism" uye "intelligent upgrade system". IPS yemazuva ano inogara ichigadzirisa database yeattack signature kuti ienderane nenzira dzemazuva ano dzehacker attack. Zvimwe zvigadzirwa zvepamusoro-soro zvinotsigirawo "behavioral analysis and learning", izvo zvinogona kuona otomatiki kurwiswa kutsva nekusingazivikanwe (senge zero-day exploits). Sisitimu yeIPS inoshandiswa nesangano rezvemari yakawana ndokuvhara SQL injection attack ichishandisa kusazivikanwa kwekusaziva nekuongorora frequency yemibvunzo yedatabase isina kujairika, ichidzivirira kutapurwa kwedata rekutengeserana kwepakati.
Kunyangwe IDS neIPS dziine mabasa akafanana, pane misiyano mikuru: kubva pamaonero ebasa, IDS "inotarisa pasina kungwarira + ichinyevera", uye haipindire zvakananga mukufamba kwenetiweki. Yakakodzera zviitiko zvinoda kuongororwa kwakazara asi zvisingade kukanganisa sevhisi. IPS inomiririra "active Defense + Intermission" uye inogona kudzikamisa kurwiswa munguva chaiyo, asi inofanira kuve nechokwadi chekuti haifungi zvisizvo nezvekufamba kwakajairika (nhema dzinogona kukonzera kukanganiswa kwebasa). Mumashandisirwo anoshanda, vanowanzo "shandira pamwe" -- IDS ine basa rekutarisa nekuchengetedza humbowo zvakakwana kuti iwedzere masiginecha ekurwiswa kweIPS. IPS ine basa rekudzingirira panguva chaiyo, kutyisidzira kwekudzivirira, kuderedza kurasikirwa kunokonzerwa nekurwiswa, uye kugadzira jira rakazara rekuchengetedza re "detection-defense-traceability".
IDS/IPS inoita basa rakakosha mumamiriro akasiyana-siyana: muma network epamba, kugona kuri nyore kweIPS kwakadai sekubata ma "attack interception" kwakavakirwa muma routers kunogona kudzivirira kubva kuma "common port scans" uye ma "malicious links"; Mu network yebhizinesi, zvakakosha kuisa zvishandiso zvehunyanzvi zveIDS/IPS kuchengetedza maseva emukati nemadatabase kubva mukurwiswa kwakanangana. Mumamiriro ezvinhu e "cloud computing", IDS/IPS yemuno inogona kuchinjika kuma cloud servers anogona kukwira kuti aone traffic isina kujairika pakati pevanogara. Nekuvandudzwa kuri kuitwa nzira dzekurwisa ma hacker, IDS/IPS iri kukurawo munzira ye "AI intelligent analysis" uye "multi-dimensional correlation detection", zvichiwedzera kuvandudza kururama kwekudzivirira uye kumhanya kwekupindura kwekuchengetedzwa kwenetwork.
