Tej zaum koj tau hnov tias lub Windows 7 lossis Windows 8 firewall (zoo li lwm lub ua haujlwm rau lub khoos phis tawm) yog qhov tseem ceeb ntawm kev tiv thaiv kev tiv thaiv. Tab sis koj puas paub tias nws yog dab tsi thiab nws ua dab tsi? Coob leej tsis paub. Hauv tsab xov xwm no kuv yuav sim ua kom nrov npe txog dab tsi lub foob pob hluav taws yog (nws tseem hu ua lub foob pob hluav taws), vim li cas nws xav tau thiab qee yam ntxiv cuam tshuam nrog cov ncauj lus. Kab lus no yog npaj rau cov pib tshiab.
Lub ntsiab ntawm lub laj kab hluav taws kub yog tias nws tswj hwm lossis lim txhua qhov teeb meem (cov ntaub ntawv xa tawm hauv lub network) nruab nrab ntawm lub koos pis tawj (lossis cheeb tsam hauv cheeb tsam) thiab lwm yam sib koom, xws li Is Taws Nem, uas feem ntau tshwm sim. Tsis muaj kev siv lub foob pob hluav taws, txhua hom tsheb tuaj yeem hla tau. Thaum lub foob pob hluav taws raug qhib, tsuas yog kev khiav tawm network uas tau tso cai los ntawm kev cai firewall hla dhau.
Saib ntxiv: yuav ua li cas thiaj tsis ua haujlwm ntawm Windows firewall (ua kom lub Windows firewall yuav xav ua haujlwm lossis nruab program)
Vim li cas nyob rau hauv Windows 7 thiab tshiab dua cov ntawv ntsa yog ib feem ntawm lub system
Lub Windows 8 Hluav Taws Xob
Ntau tus neeg siv niaj hnub no siv cov routers mus nkag rau Is Taws Nem los ntawm ntau cov khoom siv hauv ib zaug, uas, hauv ntsiab, nws tseem yog hom hluav taws. Thaum siv Internet txuas ncaj qha los ntawm xaim lossis DSL modem, lub khoos phis tawj tau muab rau pej xeem IP chaw nyob, uas tuaj yeem nkag los ntawm lwm lub khoos phis tawm hauv lub network. Txhua cov kev pabcuam hauv network uas khiav ntawm koj lub khoos phis tawm, xws li Windows cov kev pabcuam rau kev sib koom luam ntawv lossis cov ntawv, tej thaj chaw deb desktop, kuj yuav muaj rau lwm lub koos pis tawj. Nyob rau tib lub sijhawm, txawm tias koj kaw qhov chaw taws teeb nkag mus rau qee yam kev pabcuam, kev hem thawj ntawm kev sib txuas tsis zoo tseem nyob - ua ntej ntawm txhua tus, vim tias tus neeg siv nruab nrab xav tsawg me ntsis txog dab tsi khiav ntawm nws lub Windows OS thiab tseem tos rau kev txuas nkag, thiab qhov thib ob vim sib txawv Hom kev ruaj ntseg qhov uas tso cai rau koj mus txuas rau cov chaw pabcuam hauv chaw taws teeb nyob rau hauv cov teeb meem ntawd thaum nws nyuam qhuav khiav, txawm tias nkag mus rau nws tau txwv tsis pub. Lub foob pob hluav taws tsuas tsis pub xa cov ntaub ntawv thov kev pabcuam siv qhov chaw tsis muaj zog.
Thawj version ntawm Windows XP, zoo li dhau los ua ntej ntawm lub Windows, tsis muaj qhov thaiv hluav taws xob ua. Thiab tsuas yog nrog kev tso tawm ntawm Windows XP, qhov ubiquity ntawm Internet tau sib txig sib luag. Qhov uas tsis muaj lub foob pob hluav taws hauv kev xa tawm, nrog rau kev paub tsis tau zoo ntawm cov neeg siv hais txog kev ruaj ntseg hauv Is Taws Nem, ua rau muaj qhov tseeb tias txhua lub computer txuas nrog Internet nrog Windows XP yuav kis tau nyob hauv ob peb feeb ntawm kev ua txhaum.
Thawj lub foob pob hluav taws tau qhia rau hauv Windows XP Service Pob 2 thiab txij thaum ntawd los ntawm lub foob pob hluav taws tau qhib los ntawm lub neej yav dhau los hauv txhua hom haujlwm ntawm lub operating system. Thiab cov kev pabcuam uas peb tau tham txog saum toj no yog tam sim no cais tawm sab nraud ntawm cov tes hauj lwm sab nraud, thiab lub foob pob hluav taws txwv tsis pub txhua qhov khoom sib txuas tshwj tsis yog tias nws tau raug qhia meej meej rau hauv cov chaw firewall.
Qhov no txwv tsis pub lwm lub koos pis tawj nkag mus rau Is Taws Nem los ntawm kev sib txuas rau cov kev pabcuam hauv koj lub computer thiab, ntxiv rau, tswj kev nkag mus rau cov kev pabcuam network los ntawm koj lub network hauv cheeb tsam. Vim li no, txhua zaus koj mus txuas rau lub network tshiab, Windows nug seb nws puas yog tsev network, ua haujlwm lossis pej xeem. Thaum muaj kev sib txuas nrog lub vev xaib hauv tsev, Windows Firewall tso cai nkag mus rau cov kev pabcuam no, thiab thaum txuas nrog lub network pej xeem, nws txwv tsis pub nkag.
Lwm qhov hluav taws xob nta
Lub foob pob hluav taws yog teeb meem (vim li lub npe hu ua firewall - los ntawm lus Askiv "Hluav Taws Phab Ntsa") nruab nrab ntawm lub network sab nraud thiab khoos phis tawj (lossis cheeb tsam hauv nroog), uas nyob hauv qab nws tiv thaiv. Lub ntsiab kev ruaj ntseg tseem ceeb ntawm cov foob pob hluav taws rau kev siv hauv tsev yog los thaiv tag nrho cov kev nkag tsis tau hauv Is Taws Nem. Txawm li cas los xij, qhov no nyob deb ntawm txhua qhov uas lub foob pob hluav taws tuaj yeem ua. Xav txog tias lub foob pob hluav taws yog "nruab nrab" lub network thiab khoos phis tawj, nws tuaj yeem siv los txheeb xyuas tag nrho cov kev nkag mus los hauv thiab tawm ntawm lub network thiab txiav txim siab ua dab tsi nrog nws. Piv txwv li, ib lub foob pob hluav taws tuaj yeem tsim kho kom thaiv qee yam kev cuam tshuam ntawm kev tawm ntawm sab nrauv, txhawm rau nkag cov kev ua ub no hauv network, lossis txhua qhov sib txuas hauv lub network.
Hauv Windows Firewall, koj tuaj yeem tsim kho ntau txoj cai uas yuav pub lossis txwv qee yam kev thauj. Piv txwv li, kev txuas nkag tuaj yeem tsuas yog tso cai los ntawm tus neeg rau zaub mov nrog qhov chaw nyob IP tshwj xeeb, thiab tag nrho lwm qhov kev thov yuav raug tsis lees paub (qhov no tuaj yeem siv tau thaum koj xav tau txuas rau qhov program hauv computer los ntawm lub koos pij tawj ua haujlwm, txawm hais tias nws zoo dua los siv VPN).
Lub foob pob hluav taws tsis yog software txhua lub sijhawm zoo ib yam li lub qhov rai paub zoo. Hauv kev lag luam hauv lub tuam txhab, cov khoom siv thev naus laus zis thiab kho vajtse uas ua tiav cov haujlwm ntawm lub foob pob hluav taws tuaj yeem siv.
Yog tias koj muaj Wi-Fi router (lossis tsuas yog router) hauv tsev, nws kuj ua raws li ib hom kev kho vajtse, ua tsaug rau nws cov NAT muaj nuj nqi, uas txwv tsis pub nkag mus sab nraud rau cov khoos phis tawm thiab lwm yam khoom siv txuas nrog router.
