Umnyombo we-firewall ukuthi ilawula noma ihlungi yonke ithrafikhi (idatha edluliselwe kwinethiwekhi) phakathi kwekhompyutha (noma inethiwekhi yendawo) namanye amanethiwekhi, okuvame kakhulu. Ngaphandle kokusebenzisa i-firewall, noma yiluphi uhlobo lwethrafikhi lungabanjwa. Lapho i-firewall ivuliwe, yilokho kuphela okudlula kwethrafikhi yenethiwekhi, okuvunyelwe yimithetho ye-firewall. Kungathakazelisa: ukuthi ungavimba kanjani uhlelo lokufinyelela kwi-Intanethi.
Bheka futhi: Ungawukhubaza kanjani iWindows Firewall (iWindows Firewall Ukukhubaza Ma kungacelwa ukuthi kusebenze noma kufake izinhlelo)
Kungani ku-Windows 7 kanti izinguqulo ezintsha ze-firewall ziyingxenye yohlelo
Abasebenzisi abaningi kakhulu namuhla basebenzisa ama-routers ukufinyelela i-Intanethi ngasikhathi sinye kusuka kumadivayisi athile, okuyinto, futhi, futhi, futhi, futhi uhlobo lwe-firewall. Uma usebenzisa ukuxhumana okuqondile kwe-inthanethi ngentambo noma nge-DSL Modem, ikhompyutha yabelwa ikheli le-IP le-Public IP lapho ungaxhumana khona nanoma iyiphi enye ikhompyutha kunethiwekhi. Noma yiziphi izinsizakalo zenethiwekhi ezisebenza kwikhompyutha yakho, njengezinsizakalo zeWindows zokwabelana ngamaphrinta noma amafayela, ama-desktops akude angatholakala kwamanye amakhompyutha. Ngasikhathi sinye, noma ngabe ukhubaza ukufinyelela okukude kwezinsizakalo ezithile, usongo lokuxhumana olunonya lisaqhubeka - okokuqala, ngoba umsebenzisi ojwayelekile ucabanga okuncane ngokuthi kuqalwa ukuthi ku-Windows OS futhi kulindele ukuxhumana okuzayo, Futhi okwesibili - ngenxa yezinhlobonhlobo zohlobo lwezimbobo zokuphepha ezikuvumela ukuthi uxhumeke kwinsizakalo ekude ezimeni lapho imane isebenza khona, noma ngabe ukuxhumana okungenayo kuvinjelwe kukho. I-Firewall imane nje ayivumeli ukuthumela isicelo kwisicelo esisebenzisa ubungozi.
Uhlobo lokuqala lweWindows XP, kanye nezinhlobo zangaphambilini zeWindows, aluqukethe i-firewall eyakhelwe ngaphakathi. Futhi nje ukukhishwa kweWindows XP futhi kuhambisane nokusatshalaliswa kwe-Intanethi okusabalele. Ukuntuleka kwe-firewall ekuhlinzekweni, kanye nokubhala okuncane kwabasebenzisi kuhlelo lokuphepha lwe-Intanethi, kuholele eqinisweni lokuthi noma iyiphi ikhompyutha exhunywe kwi-Intanethi ngeWindows XP ingatheleleka phakathi kwamathuba ambalwa uma kwenzeka kwezenzo ezihlosiwe.
I-firewall yokuqala yeWindows Firewall yethulwe ku-Windows XP Service Pack 2 futhi kusukela lapho isicishamlilo ifakiwe kuzo zonke izinhlobo zohlelo lokusebenza. Futhi lezo zinsizakalo esazikhuluma ngenhla manje zihlukaniswe namanethiwekhi angaphandle, futhi i-firewall yenqabela konke ukuxhumana okungenayo ngaphandle kokuthi kuvunyelwe ngqo kuzilungiselelo ze-Firewall.
Lokhu kuvimbela ukuxhumana kwamanye amakhompyutha kusuka kwi-Intanethi kuya kwizinsizakalo zasendaweni kwikhompyutha yakho futhi, ngaphezu kwalokho, kulawula ukufinyelela kwezinsizakalo zenethiwekhi kusuka kunethiwekhi yakho yendawo. Kungenxa yalesi sizathu ukuthi, noma nini lapho ixhumeke kwinethiwekhi entsha yeWindows, ibuzwa ngenethiwekhi yasekhaya, ukusebenza noma esidlangalaleni. Uma uxhumeke kwinethiwekhi yasekhaya, iWindows Firewall ivumela ukufinyelela kwalezi zinsizakalo, futhi uma kuxhunyiwe emphakathini - kwenqatshelwe.
Eminye imisebenzi ye-firewall
I-firewall iyisithiyo (yingakho igama le-firewall - kusuka esiNgisini. "Udonga lomlilo") phakathi kwenethiwekhi yangaphandle nekhompyutha (noma inethiwekhi yendawo), engaphansi kokuvikelwa kwayo. Umsebenzi oyinhloko wokuvikela i-firewall yokusetshenziswa kwasekhaya ukuvinjwa kwawo wonke amathrafikhi e-intanethi angafuneki. Kodwa-ke, lokhu akukhona konke lokho okungenzeka ukuthi i-firewall. Njengoba kunikezwe iqiniso lokuthi i-firewall "iphakathi" kwenethiwekhi kanye nekhompyutha, ingasetshenziselwa ukuhlaziya yonke ithrafikhi engenayo noma ephumayo futhi unqume ukuthi wenzeni ngayo. Isibonelo, i-firewall ishes okufanele ilungiselelwe ukuvimba uhlobo oluthile lwethrafikhi ephumayo, gcina iphephabhuku umsebenzi wenethiwekhi osolisayo noma konke ukuxhumana kwenethiwekhi.
Ku-Windows Firewall, ungahlela imithetho ehlukahlukene ezovumela noma yenqabe izinhlobo ezithile zethrafikhi. Isibonelo, ukuxhumana okungenayo kungavunyelwa kuphela kwiseva ngekheli elithile le-IP, futhi zonke ezinye izicelo zizophambuka (lokhu kungaba wusizo lapho udinga ukuxhuma ohlelweni kwikhompyutha yakho, yize kungcono Sebenzisa i-VPN).
I-Firewall ayihlali isoftware njenge-Windows Firewall eyaziwayo. Emkhakheni webhizinisi, isoftware elungiselelwe kahle nezakhiwo zehadiwe ezenza imisebenzi yodumo ingasetshenziswa.
Uma une-router yasekhaya ye-Wi-Fi (noma nje), futhi isebenza njengohlobo lwe-firewall ye-Hardware, ngenxa yomsebenzi wayo we-nat, okuvimbela ukufinyelela kwamakhompyutha namanye amadivaysi axhunyiwe kwi-router.
