Lapho uvikela inethiwekhi yakho kanye nedatha ekusongelweni kwe-inthanethi, Uhlelo Lokuvimbela Ukungena (IPS) kanye ne-firewall kudlala indima ebalulekile. Nokho, banemisebenzi nezici ezihlukile. Lesi sihloko sizohlola umehluko phakathi kwe-IPS kanye ne-firewall, ikusiza ukuthi uqonde ukuthi yiliphi ithuluzi elizifanela kangcono izidingo zakho ze-cybersecurity.
Yini i-IPS?
I-Intrusion Prevention System (IPS) iyithuluzi le-cybersecurity eliqapha ithrafikhi yenethiwekhi ukuze kutholwe izinsongo ezingaba khona futhi lithathe isinyathelo ukuze kuzigweme. Ihlaziya amaphakethe enethiwekhi ngesikhathi sangempela futhi iwaqhathanise nesizindalwazi samasignesha aziwayo okuhlasela. Uma ibhokisi lifana nesiginesha yokuhlasela eyaziwayo, i-IPS ingavimba noma iwise iphakethe, ivimbele ukuhlasela ekufinyeleleni okuqondiwe. I-IPS ingathola futhi imise ukuziphatha kwenethiwekhi okungavamile okungase kubonise ukuhlasela okusha noma okungaziwa. Sekukonke, i-IPS ivikela inethiwekhi yakho ezinsongweni ezaziwayo nezingaziwa.
Yini i-Firewall?
I-firewall iyidivayisi yokuphepha yenethiwekhi eqapha futhi elawula ithrafikhi yenethiwekhi engenayo nephumayo ngokusekelwe emithethweni yokuphepha enqunywe kusengaphambili. Kuwumgoqo phakathi kwenethiwekhi yangaphakathi ethembekile kanye nenethiwekhi yangaphandle engathenjwa, njenge-inthanethi. Ama-firewall angasuselwa kuhadiwe noma asekelwe kwisoftware futhi abalulekile ekuvikeleni amanethiwekhi ekufinyeleleni okungagunyaziwe, uhlelo olungayilungele ikhompuyutha, nezinye izinsongo ze-cyber. Bangavimba noma bavumele ithrafikhi ngokusekelwe kumakheli e-IP, izimbobo, nezinqubo. Ama-firewall ayingxenye ebalulekile yokuphepha kwenethiwekhi futhi avame ukusetshenziswa ngokuhambisana nezinye izindlela zokuphepha, njengama-IPS, ukuze anikeze ukuvikeleka okuphelele.
Isebenza kanjani i-IPS?
I-Intrusion Prevention System (IPS) iyithuluzi lokuphepha lenethiwekhi eliqapha ithrafikhi yenethiwekhi ngomsebenzi omubi futhi lithathe isinyathelo ukuze liwuvimbele. Ngokungafani ne-firewall, ngokuyinhloko egxile ekuvimbeni noma ekuvumeleni ithrafikhi ngokusekelwe emithethweni enqunywe kusengaphambili, i-IPS iqhubekela phambili ngokuhlaziya amaphakethe enethiwekhi nokuhlonza izinsongo ezingaba khona ngesikhathi sangempela. Isebenzisa ukutholwa okusekelwe kusiginesha, ukutholwa okudidayo, nokuhlaziya ukuziphatha ukuze kuhlonzwe futhi kuvinjwe ithrafikhi esolisayo noma enonya. Uma i-IPS ithola ukusongela okungaba khona, ingathatha isinyathelo esisheshayo, esifana nokuvimba ikheli le-IP eliwumthombo noma ukuthumela isaziso kumphathi wenethiwekhi. Ama-IPS aklanyelwe ukunikeza isendlalelo esengeziwe sokuvikela ngokumelene nezinsongo ezithuthukisiwe futhi angahambisana namakhono we-firewall ukuthuthukisa ukuphepha kwenethiwekhi kukonke.
Isebenza kanjani i-Firewall?
I-firewall iyisisetshenziswa sokuvikela senethiwekhi esisebenza njengesithiyo phakathi kwenethiwekhi yangaphakathi ne-inthanethi yangaphandle. Ihlola ithrafikhi yenethiwekhi engenayo nephumayo bese inquma ukuthi iyayivumela noma ivimbe ithrafikhi ethile ngokusekelwe emithethweni enqunywe kusengaphambili. Umlawuli wenethiwekhi angasetha le mithetho ngokusekelwe kumthombo noma ikheli le-IP, inombolo yembobo, noma iphrothokholi. Uma iphakethe ledatha lizama ukungena noma ukuphuma kunethiwekhi, i-firewall iyalihlola ngokuphikisana nale mithetho. Uma iphakheji ihlangabezana nemibandela ebekwe yimithethonqubo, ivunyelwe ukudlula. Uma ingahlangabezani nezidingo, iyavinjwa. Ama-firewall angaphinda ahlinzeke ngezici zokuphepha ezengeziwe, njengokutholwa nokuvinjelwa kokungena, usekelo lwenethiwekhi yangasese ebonakalayo (VPN), kanye nokuhlunga okuqukethwe. Sekukonke, i-firewall isebenza njengomgcini-sango wethrafikhi yenethiwekhi, isiza ukuvikela inethiwekhi ekufinyeleleni okungagunyaziwe kanye nezinsongo ezingaba khona.
Umehluko obalulekile phakathi kwe-IPS ne-Firewall.
Nakuba i-IPS (Intrusion Prevention System) kanye nezindonga zomlilo zingamathuluzi abalulekile e-cybersecurity, kokubili kunomehluko obalulekile. I-firewall isebenza njengesithiyo phakathi kwenethiwekhi yangaphakathi kanye ne-inthanethi yangaphandle, elawula ithrafikhi engenayo nephumayo ngokusekelwe emithethweni enqunywe kusengaphambili. Ngakolunye uhlangothi, i-IPS idlula nje ukuqapha nokuvimbela ithrafikhi. Iskena ithrafikhi yenethiwekhi ukuze ithole izinsongo ezingaba khona futhi ithatha isinyathelo esisheshayo ukuzinqanda. Lokhu kuhlanganisa ukuthola nokuvimbela imisebenzi enonya, njengemizamo yokungena, uhlelo olungayilungele ikhompuyutha, nokufinyelela okungagunyaziwe. I-firewall igxile ekulawulweni kwethrafikhi, kuyilapho i-IPS igxile ekutholeni usongo nokuvimbela. Kuvamile ukuthi izinhlangano zisebenzise kokubili i-firewall kanye ne-IPS ngokuhlangene ukuze zinikeze ukuphepha kwenethiwekhi okuphelele.
