Lub foob pob hluav taws (lossis firewall) yog ib qho txhais tau tias los ntawm cov txheej txheem ntawm kev txwv kev nkag mus rau lub khoos phis tawm ntawm Is Taws Nem. Nws muaj ob hom firewalls: software thiab kho vajtse.
Nrog kev pab ntawm firewall, nws muaj peev xwm ua kom muaj kev ruaj ntseg ntawm lub khoos phis tawm: hacker tawm tsam, nkag mus ntawm cov phiaj xwm tsis zoo yuav ua tsis tau. Ib qho ntxiv ntxiv yog lub foob pob hluav taws tiv thaiv cov neeg phem dhau los siv koj lub khoos phis tawm rau lawv lub hom phiaj, piv txwv, tawm tsam cov computers ntawm lwm tus neeg siv. Qhov tseem ceeb tshwj xeeb yog kev siv firewalls rau cov khoos phis tawj uas muaj qhov sib txuas nyob rau hauv Is Taws Nem. Txhawm rau pib nws, cia li xaiv "Pib" -> "Tswj Vaj Huam Sib Luag" -> "Windows Firewall". Kev siv tus txheej txheem hluav taws xob tuaj yeem muab kev tiv thaiv tiv thaiv cov kev hem thawj saum toj no. Siv cov lus qhia los ntawm lub operating system los teeb tsa nws. Kev teeb tsa raug ua tiav los ntawm teeb tsa cov cai tshwj xeeb thiab kev txwv rau qee cov haujlwm, chaw nres nkoj, kev pabcuam, thiab lwm yam. Lwm lub software hluav taws xob kuj tseem siv tau. Lawv yuav txawv nyob rau hauv lub peev xwm muab rau tus neeg siv, nyob rau hauv kev sib zog thiab tob dua kev kho kom haum, thiab hauv lub interface. Piv txwv ntawm software firewalls yog NetworkShield Firewall, Avira Internet Security, BitDefender Internet Kev Ruaj Ntseg, thiab lwm yam. Tus kho vajtse phab ntsa yog nkag siv lub vev xaib browser. Qhov chaw nyob IP ntawm lub khoos phis tawm yog nkag mus rau hauv qhov chaw nyob bar, thiab tom qab ntawd nplooj ntawv nrog nws cov chaw qhib. Cais, nws yuav tsum raug sau tseg tias muaj ntau tus routers muaj kab hluav taws kub ua kom zoo nkauj. Piv txwv ntawm cov khoom siv khoos phis tawm yog SonicWall, Cisco PIX, thiab lwm yam. Koj yuav tsum paub tias lub foob pob hluav taws tuaj yeem cuam tshuam nrog txhua qhov program programs hauv computer. Qhov no tuaj yeem ua rau qee cov teeb meem hauv kev ua haujlwm ntawm lub software. Nws yog qhov ua tau los daws qhov teeb meem los ntawm kev hloov kho cov chaw firewall. Tsis tas li, qhov tsis sib xws tuaj yeem tshwm sim los ntawm software dhau los - hloov tshiab nws feem ntau yog daws qhov teeb meem.
