Esikhathini samanje sedijithali, ukuphepha kwenethiwekhi kubaluleke kakhulu. Isici esisodwa esibalulekile se ukuvikelwa kwenethiwekhi ukuphepha kwe-IPS. Kepha kuyini ngempela ukuphepha kwe-IPS, futhi kusebenza kanjani? Lo mhlahlandlela obanzi uhlose ukuqonda ukuphepha kwe-IPS kanye nendima yakhona ekuvikeleni amanethiwekhi ezinsongweni ezingaba khona.
Kuyini ukuphepha kwe-IPS?
Ukuphepha kwe-IPS, noma ukuphepha kwe-Intrusion Prevention System, ubuchwepheshe bokuphepha kwenethiwekhi obuqapha ithrafikhi yenethiwekhi yemisebenzi enonya futhi buthathe izinyathelo zokuyivimbela. Isebenza ngokuhlaziya amaphakethe enethiwekhi ngesikhathi sangempela, ukuwaqhathanisa nesizindalwazi samasiginesha okuhlasela aziwayo, nokuvimbela noma ukunciphisa noma iyiphi ithrafikhi esolisayo noma enonya. Ukuphepha kwe-IPS kusebenza njengesithiyo phakathi kwe- inethiwekhi yangaphakathi nezinsongo zangaphandle, okusiza ukuvimbela ukufinyelela okungagunyaziwe, ukwephulwa kwedatha, nokunye ukuhlaselwa ku-inthanethi. Idlala indima ebalulekile ekugcineni ubuqotho nokugcinwa kuyimfihlo kwezinhlelo zenethiwekhi nokuvikela ulwazi olubucayi ukuthi lungafakwa engozini.
Ukubaluleka kokuphepha kwe-IPS ekuvikelweni kwenethiwekhi.
Ukuphepha kwe-IPS kuyisici esibalulekile sokuvikela inethiwekhi, njengoba kusiza ukuvikela izinsongo nokuhlaselwa kwe-inthanethi okuhlukahlukene. Ngokukhula kobuchwepheshe kanye nemvamisa yokuhlaselwa ku-inthanethi, izinhlangano zidinga izinyathelo zokuphepha eziqinile ukuze zivikele amanethiwekhi azo kanye nolwazi olubucayi. Ukuphepha kwe-IPS kusebenza njengesithiyo phakathi kwenethiwekhi yangaphakathi nezinsongo zangaphandle, njalo ukuqapha ithrafikhi yenethiwekhi nganoma yiziphi izimpawu zezenzo ezinonya. Ukuvikeleka kwe-IPS kungathola futhi kuvimbele noma iyiphi ithrafikhi esolisayo noma enonya ngokuhlaziya amaphakethe enethiwekhi ngesikhathi sangempela futhi awaqhathanise nesizindalwazi samasiginesha aziwayo okuhlasela. Le ndlela yokusebenza isiza ukuvimbela ukufinyelela okungagunyaziwe, ukwephulwa kwedatha, nokunye ukuhlaselwa ku-inthanethi, iqinisekisa ubuqotho nokugcinwa kuyimfihlo kwezinhlelo zenethiwekhi. Ukusebenzisa ukuphepha kwe-IPS kubalulekile ukuze izinhlangano zigcine ukuzivikela okuqinile ezinsongweni eziguqukayo ze-inthanethi nokuvikela impahla yazo ebalulekile.
Indlela ukuphepha kwe-IPS kusebenza ngayo.
Ukuphepha kwe-IPS kuqapha ithrafikhi yenethiwekhi futhi ihlaziya amaphakethe enethiwekhi ngesikhathi sangempela. Iqhathanisa amaphakheji ngokumelene nesizindalwazi samasiginesha aziwayo okuhlasela ukuze kutholwe ithrafikhi esolisayo noma enonya. Uma ukusongela okungaba khona kukhonjwa, isistimu ye-IPS ithatha isinyathelo ukuvimba noma ukunciphisa usongo, njengokuwisa amaphakethe anonya noma ukuxwayisa abalawuli benethiwekhi. Ukuphepha kwe-IPS kusebenzisa amasu ahlukahlukene ukuhlonza kanye vimbela ukuhlaselwa kwe-cyber, okuhlanganisa okususelwe kusiginesha, okususelwe kokudidayo, nokutholwa okusekelwe ekuziphatheni. Isebenza njengesithiyo phakathi kwenethiwekhi yangaphakathi nezinsongo zangaphandle, iqinisekisa ubuqotho nokugcinwa kuyimfihlo kwezinhlelo zenethiwekhi. Ngokusebenzisa ukuphepha kwe-IPS, izinhlangano zingavikela ekuthuthukisweni kwezinsongo ze-inthanethi futhi zivikele izimpahla zazo ezibalulekile.
Izinhlobo ezahlukene zezinhlelo zokuphepha ze-IPS.
Izinhlobo ezimbalwa ezihlukene zezinhlelo zokuphepha ze-IPS ziyatholakala, ngayinye inezici ezihlukile namandla. Olunye uhlobo oluvamile i-IPS esekelwe kunethiwekhi (NIPS) esetshenziswe kumjikelezo wenethiwekhi ukuze kuqashwe futhi kuhlaziywe yonke ithrafikhi engenayo naphumayo. Olunye uhlobo i-IPS esekelwe kumsingathi (HIPS), efakwe kumuntu ngamunye amadivaysi noma amaseva ukuze aqaphe futhi awavikele ezinsongweni zangaphakathi. Kukhona nezinhlelo ze-IPS (vIPS), ezisekelwe kwisofthiwe futhi ezisebenza ngemishini ebonakalayo noma ezindaweni zamafu. Ukwengeza, kukhona amasistimu e-IPS asemgqeni, avimbela futhi ahlole ithrafikhi yenethiwekhi, namasistimu e-IPS angenzi lutho, aqapha ithrafikhi yenethiwekhi ngokungenzi lutho ngaphandle kokuphazamisa ukuhamba kwedatha. Uhlobo ngalunye lwesistimu yokuphepha ye-IPS lunezinzuzo nokucatshangelwa, futhi izinhlangano kufanele zikhethe leyo ehambisana kangcono nezidingo zazo ezithile zokuphepha.
Imikhuba emihle kakhulu yokusebenzisa ukuphepha kwe-IPS.
Ukusebenzisa ukuphepha kwe-IPS kudinga ukuhlela ngokucophelela nokucatshangelwa. Nansi imikhuba emihle ongayilandela:
1. Yenza uhlolo olunzulu lwengozi: Ngaphambi kokusebenzisa ukuphepha kwe-IPS, hlola izidingo ezithile zokuphepha zenhlangano yakho futhi uhlonze ubungozi obungaba khona nezinsongo.
2. Khetha isistimu ye-IPS efanele: Cabangela izici ezifana nosayizi wenethiwekhi, umthamo wethrafikhi, nesabelomali lapho ukhetha isistimu ye-IPS. Linganisa izinketho ezahlukene bese ukhetha eyodwa ehambisana nezidingo zenhlangano yakho.
3. Gcina isistimu yakho ye-IPS isesikhathini samanje: Njalo buyekeza i-firmware yesistimu yakho ye-IPS kanye nesofthiwe ukuze uqinisekise ukuthi inamapeshi akamuva okuvikela nezici. Lokhu kusiza ukuvikela ezinsongweni ezivelayo kanye nokuba sengozini.
4. Lungiselela isistimu yakho ye-IPS kahle: Yenza ngokwezifiso izilungiselelo zesistimu yakho ye-IPS ukuze zifane nendawo yenethiwekhi yenhlangano yakho nezinqubomgomo zokuphepha. Lokhu kuhlanganisa ukusetha imingcele efanele, imithetho, nezihlungi.
5. Qaphela futhi uhlaziye izexwayiso ze-IPS: Qaphela futhi uhlaziye izexwayiso ezikhiqizwe isistimu yakho ye-IPS. Phenya noma yimuphi umsebenzi osolisayo noma izinsongo ezingaba khona ngokushesha ukuze unciphise ubungozi.
6. Hlanganisa i-IPS nezinye izixazululo zokuphepha: I-IPS kufanele ibe yingxenye yesu elibanzi lokuvikela. Ihlanganise nezinye izixazululo zokuphepha ezifana nezindonga zokuvikela, isofthiwe yokuvikela amagciwane, kanye nezinhlelo ze-SIEM (Ulwazi Lokuvikeleka Nokuphathwa Kwemicimbi) ukuze uthole ukuvikelwa okuthuthukisiwe.
7. Hlala ubuyekeze futhi ubuyekeze izinqubomgomo ze-IPS: Njengoba izidingo zokuphepha zenhlangano yakho zishintsha, buyekeza futhi ubuyekeze izinqubomgomo zakho ze-IPS ngokufanele. Lokhu kuqinisekisa ukuthi uhlelo lwakho lwe-IPS luhlala lusebenza futhi luhambisana nezidingo zakho zokuphepha.
8. Qeqesha abasebenzi bakho: Nikeza izinhlelo zokuqeqesha nokuqwashisa mayelana nezindlela ezihamba phambili zokuphepha ze-IPS. Twakhe ubasiza baqonde ukubaluleka kwe-IPS nokuthi bangasabela kanjani ezinsongweni ezingase zibe khona.
9. Yenza ukucwaninga nokuhlola ngezikhathi ezithile: Hlola njalo ukusebenza kwesistimu yakho ye-IPS ngokusebenzisa ukucwaninga nokuhlola ukungena. Khomba noma yibuphi ubuthakathaka noma izindawo okufanele zithuthukiswe futhi uthathe izinyathelo ezifanele.
10. Hlala unolwazi mayelana nezinsongo ezivelayo: Hlala unolwazi ngamathrendi akamuva okuphepha ku-inthanethi nezinsongo. Lolu lwazi lukusiza ukuthi ulungise ngokushesha izindlela zakho zokuphepha ze-IPS ukuze uhlale ngaphambi kwezingozi ezingaba khona.
