Ama-Firewall Network avikela inethiwekhi yonke kusuka ezingeneni ezingenayo
I-firewall yenethiwekhi ivikela inethiwekhi yekhompyutha ekufinyeleleni okungagunyaziwe. Kungenzeka kube idivayisi ye- hardware , uhlelo lwesofthiwe, noma inhlanganisela yale mibini.
Amaprosesa asetshenziselwa inethiwekhi avikele inethiwekhi yekhompyutha yangaphakathi ngokumelene nokufinyelela okunonya kusuka ngaphandle, njengamawebhusayithi aphethwe yi-malware noma amachweba angenasiphequluli avulekile . Ungabathola noma yikuphi inethiwekhi isetshenzisiwe, njengekhaya, isikole, ibhizinisi noma ngisho ne- intranethi .
I-firewall yenethiwekhi ingahle ilungiselelwe ukukhawulela ukufinyelela kwangaphandle kubasebenzisi bangaphakathi, njengokungathi ukulawulwa kwabazali noma ukuvala indawo yokusebenza, kokubili okuvimbela ukufinyeleleka kokungena kwezokugembula kanye namawebhusayithi omdala, phakathi kwezinye izinhlobo eziningi zokuqukethwe.
Indlela i-Firewall isebenza ngayo
Uma i-firewall isetshenziselwa ukukwazi ukugcwele, ihlale iqapha yonke imoto engenayo nephumayo. Okwenza i-firewall ihluke kumcwaningi womgwaqo nje kuphela ukuthi ingasethwa futhi ukuvimba izinto ezithile.
I-firewall ingase ikhubaza izicelo ezithile ukusuka ekufinyeleleni kwinethiwekhi, ukuvimba ama- URL ekulayisheni, nokuvimbela ithrafikhi ngokusebenzisa amaphethelo athile enethiwekhi.
Amanye amabhuloho angasetshenziswa ngisho nemodi lapho evimba yonke into uze uvumele ngokucacile ukufinyelela okukodwa. Lena yindlela eyodwa yokuvimbela yonke into kunethiwekhi ukuze ukwazi ukusetha ngesandla izivikelo ngokumelene nezinsongo ezihlobene nenethiwekhi.
I-Firewall Software ne-Broadband Routers
Imikhiqizo eminingi ye-router yenethiwekhi yekhaya ifaka phakathi ukwesekwa kwe-firewall eyakhelwe ngaphakathi. I-interface yokuphatha yalezi routers ihlanganisa izinketho zokucushwa kwe-firewall. Ama-firewall router angavaliwe (akhutshaziwe), noma angasethwa ukuhlunga izinhlobo ezithile zethrafikhi yenethiwekhi ngokusebenzisa imithetho ebizwa nge-firewall.
Ithiphu: Bheka ukuthi ungayenza kanjani i-Firewall yakho engenakulintshi eyakhelwe ngaphakathi, ukuze ufunde kabanzi, kufaka phakathi ukuthi ungahlola kanjani ukuthi i-router isekela ngisho ne-firewall.
Kukhona izinhlelo eziningi ze-firewall zamasofthiwe ozifaka ngqo kwi- hard drive yekhompyutha eyidinga. Lezi zibhamu, noma kunjalo, zivikela kuphela ikhompyutha ezisebenzayo; izinkinobho zomlilo zivikela inethiwekhi yonke. Kunjenge-firewall yenethiwekhi, izibhamu zomlilo ezisekelwe kukhompyutha zingakhutshazwa, futhi .
Ngaphandle kwezinhlelo ezinikezelwe umlilo we-firewall izinhlelo ziyi-antivirus ezivame ukufaka i-firewall eyakhelwe ngaphakathi nokufaka.
Ama-firewall Network kanye nama-proxy amaseva
Olunye uhlobo olujwayelekile lwe-firewall yenethiwekhi yisiphakeli se-proxy. Amaseva wommeleli enza njengomxhumanisi phakathi kwamakhompyutha wangaphakathi namanethiwekhi wangaphandle ngokuthola futhi ngokukhetha ukuvimbela amaphakethe wedatha kumngcele wenethiwekhi.
Lezi zibhamu zokuxhumana zomculo nazo zinikeza isilinganiso esengeziwe sokuphepha ngokufihla amakheli angaphakathi we- LAN kusuka kwikhompyutha engaphandle. Kwimvelo ye-proxy server firewall, izicelo zenethiwekhi ezivela kumakhasimende amaningi zivela kumuntu ovela ngaphandle njengabo bonke abavela ekheli elifanayo le-server yeseva.
