Dongosolo Lozindikira Kulowerera (IDS)Ili ngati scout mu netiweki, ntchito yayikulu ndikupeza momwe zinthu zilili ndikutumiza alamu. Mwa kuyang'anira kuchuluka kwa anthu omwe akubwera pa netiweki kapena momwe zinthu zilili nthawi yeniyeni, imayerekeza "laibulale yolumikizirana" yomwe yakhazikitsidwa kale (monga code yodziwika bwino ya kachilombo, mawonekedwe owukira a hacker) ndi "baseline ya khalidwe labwinobwino" (monga kuchuluka kwa anthu omwe akubwera, mawonekedwe otumizira deta), ndipo nthawi yomweyo imayambitsa alamu ndikulemba zolemba mwatsatanetsatane akangopezeka cholakwika. Mwachitsanzo, pamene chipangizo nthawi zambiri chimayesa kuphwanya mawu achinsinsi a seva, IDS imazindikira mawonekedwe osazolowereka olowera, kutumiza mwachangu chidziwitso cha chenjezo kwa woyang'anira, ndikusunga umboni wofunikira monga adilesi ya IP yowukira ndi kuchuluka kwa kuyesera kupereka chithandizo cha kutsata pambuyo pake.
Malinga ndi malo ogwiritsira ntchito, IDS ikhoza kugawidwa m'magulu awiri. Ma IDS a Network (NIDS) amayikidwa m'magawo ofunikira a netiweki (monga zipata, ma switch) kuti ayang'anire kuchuluka kwa magalimoto a netiweki yonse ndikuwona momwe zinthu zilili pazida zosiyanasiyana. Mainframe IDS (HIDS) amayikidwa pa seva imodzi kapena terminal imodzi, ndipo amayang'ana kwambiri momwe wolandila amagwirira ntchito, monga kusintha mafayilo, kuyambitsa njira, kukhalapo kwa madoko, ndi zina zotero, zomwe zimatha kujambula molondola kulowerera kwa chipangizo chimodzi. Pulatifomu ya e-commerce nthawi ina idapeza kuti deta imadutsa mu NIDS -- zambiri za ogwiritsa ntchito zinali kutsitsa ndi IP yosadziwika mochuluka. Pambuyo pa chenjezo la nthawi yake, gulu laukadaulo linatseka mwachangu kufooka ndikupewa ngozi zotaya deta.

Njira Yopewera Kulowerera (IPS)ndi "woteteza" mu netiweki, zomwe zimawonjezera kuthekera koletsa ziwopsezo pogwiritsa ntchito ntchito yozindikira ya IDS. Pamene magalimoto oipa apezeka, imatha kuchita ntchito zoletsa nthawi yeniyeni, monga kudula kulumikizana kosazolowereka, kugwetsa mapaketi oipa, kuletsa ma IP adilesi oukira ndi zina zotero, popanda kuyembekezera kulowererapo kwa woyang'anira. Mwachitsanzo, IPS ikazindikira kutumiza kwa cholumikizira cha imelo chokhala ndi mawonekedwe a kachilombo ka ransomware, nthawi yomweyo imaletsa imeloyo kuti iteteze kachilomboka kulowa mu netiweki yamkati. Poyang'anizana ndi ziwopsezo za DDoS, imatha kusefa zopempha zambiri zabodza ndikuwonetsetsa kuti seva ikugwira ntchito bwino.
Mphamvu yodzitetezera ya IPS imadalira "njira yoyankhira nthawi yeniyeni" ndi "dongosolo lanzeru lokweza". IPS yamakono nthawi zonse imasintha database ya siginecha ya kuukira kuti igwirizane ndi njira zaposachedwa za kuukira kwa hacker. Zogulitsa zina zapamwamba zimathandizanso "kusanthula khalidwe ndi kuphunzira", zomwe zimatha kuzindikira zokha ziwopsezo zatsopano ndi zosadziwika (monga kugwiritsa ntchito kwa zero-day). Dongosolo la IPS lomwe limagwiritsidwa ntchito ndi bungwe lazachuma linapeza ndikuletsa kuukira kwa SQL pogwiritsa ntchito kufooka kosadziwika posanthula kuchuluka kwa mafunso osazolowereka a database, kuletsa kusokoneza deta yayikulu.
Ngakhale kuti IDS ndi IPS zili ndi ntchito zofanana, pali kusiyana kwakukulu: kuchokera pakuwona udindo, IDS ndi "kuyang'anira mosachita + kuchenjeza", ndipo silowerera mwachindunji pa kuchuluka kwa magalimoto pa intaneti. Ndi yoyenera pazochitika zomwe zimafuna kuwunika kwathunthu koma sizikufuna kukhudza ntchitoyo. IPS imayimira "Kuteteza Kogwira Ntchito + Kupuma" ndipo imatha kuletsa ziwopsezo nthawi yeniyeni, koma iyenera kuwonetsetsa kuti siikuweruza molakwika kuchuluka kwa magalimoto wamba (zabodza zingayambitse kusokonezeka kwa ntchito). Mu ntchito zothandiza, nthawi zambiri "amagwirizana" -- IDS ili ndi udindo wowunikira ndikusunga umboni mokwanira kuti iwonjezere zizindikiro za kuukira kwa IPS. IPS ili ndi udindo woletsa ziwopsezo nthawi yeniyeni, ziwopsezo zodziteteza, kuchepetsa kutayika komwe kumachitika chifukwa cha ziwopsezo, ndikupanga kuzungulira kwathunthu kwa chitetezo cha "kupeza-kudziteteza-kutsatira".
IDS/IPS imagwira ntchito yofunika kwambiri pazochitika zosiyanasiyana: m'ma network apakhomo, mphamvu zosavuta za IPS monga kuukira komwe kumamangidwa mu ma routers kumatha kuteteza ku ma doko odziwika bwino komanso maulalo oyipa; Mu netiweki yamakampani, ndikofunikira kugwiritsa ntchito zida zaukadaulo za IDS/IPS kuti muteteze ma seva amkati ndi ma database ku ziwopsezo zolunjika. Mu zochitika za cloud computing, IDS/IPS yochokera ku cloud-native imatha kusintha ma seva amtambo omwe amatha kufalikira kuti azindikire kuchuluka kwa magalimoto pakati pa obwereka. Ndi kusinthidwa kosalekeza kwa njira zowukira za hacker, IDS/IPS ikukulanso motsatira "AI intelligent analysis" ndi "multi-dimensional correlation detection", zomwe zikupititsa patsogolo kulondola kwa chitetezo ndi liwiro la chitetezo cha netiweki.
