Lub foob pob hluav taws ua rau lub network khiav mus los ntawm nws, kom nws tuaj yeem lim tawm qee qhov kev tawm tsam, yog li txhawm rau tiv thaiv lawv ntawm kev tua ntawm lub hom phiaj khoos phis tawm. Lub foob pob hluav taws tseem tuaj yeem kaw qhov chaw nres nkoj uas tsis siv. Thiab nws tseem tuaj yeem txwv tsis pub sib txuas lus ntawm cov chaw nres nkoj tshwj xeeb thiab thaiv Trojan nees. Thaum kawg, nws tuaj yeem txwv tsis pub nkag los ntawm cov chaw tshwj xeeb, yog li tiv thaiv txhua qhov kev sib txuas lus los ntawm cov neeg tsis paub nkag.
Cybersecurity barrier
Lub foob pob hluav taws (raws li qhov taw tes thaiv, taw tes tswj) tuaj yeem txhim kho kev ruaj ntseg ntawm cov neeg sab hauv thiab txo kev txaus ntshai los ntawm lim cov kev pabcuam kev nyab xeeb. Txij li tsuas yog ua tib zoo xaiv daim ntawv thov raws cai tuaj yeem hla dhau ntawm firewall, lub network ib puag ncig muaj kev nyab xeeb dua. Piv txwv li, lub foob pob hluav taws tuaj yeem txwv tsis pub muaj kev paub txog kev nyab xeeb NFS raws tu qauv los ntawm kev nkag mus thiab tawm hauv kev tiv thaiv lub network, yog li nws tsis tuaj yeem ua rau cov neeg sab nraud siv cov kev tiv thaiv tsis muaj zog no los tua lub network sab hauv. Lub foob pob hluav taws kuj tseem tuaj yeem tiv thaiv lub network los ntawm kev ua raws li kev tawm tsam, xws li los ntawm kev tawm tsam nyob rau hauv IP xaiv thiab rov taug txoj hauv kev ICMP redirects. Lub foob pob hluav taws yuav tsum tuaj yeem thim tag nrho cov saum toj no ntawm cov pob khoom nres thiab ceeb toom rau cov thawj tswj hwm.
Ua kom muaj kev ruaj ntseg ntawm cov tswv yim ua ke
Los ntawm firewall-centric kev ruaj ntseg cov phiaj xwm teeb tsa, txhua qhov kev ruaj ntseg software (xws li password, encryption, kev txheeb xyuas qhov tseeb, kev txheeb xyuas, thiab lwm yam) tuaj yeem kho teeb meem rau ntawm firewall. Muab piv nrog faib cov teeb meem kev ruaj ntseg hauv pawg rau ib tus tswv tsev, kev tswj hwm kev ruaj ntseg hauv nruab nrab ntawm cov laj kab hluav taws kev lag luam zoo dua. Piv txwv li, thaum nkag mus rau hauv lub network, kev siv ib zaug tus password thiab lwm tus txheej txheem kev txheeb xyuas tus kheej tsis tas yuav ua rau tawg ntawm txhua tus tswv, tab sis mloog zoo ntawm firewall.
Saib xyuas kev soj ntsuam
Yog tias txhua qhov kev mus ntsib dhau ntawm firewall, tom qab ntawd firewall tuaj yeem sau cov kev mus ntsib no thiab teev cov ntaub ntawv sau cia, nrog rau muab cov txheeb cais ntawm kev siv network. Thaum muaj kev ua txhaum cai dhau los, lub foob pob hluav taws tuaj yeem ua lub tswb kom tsim nyog thiab muab cov ncauj lus kom ntxaws txog seb lub network raug soj ntsuam thiab tawm tsam. Tsis tas li, nws tseem yog ib qho tseem ceeb kom sau cov kev siv thiab siv tsis raug ntawm lub network. Qhov laj thawj thib ib yog tias nws paub tseeb tias lub foob pob hluav taws tuaj yeem tiv thaiv qhov ua kom paub thiab tawm tsam ntawm cov neeg tuaj tawm tsam, thiab seb puas muaj kev tswj hwm ntawm lub thaiv phab ntsa txaus. Thiab cov ntaub ntawv siv network yog qhov tseem ceeb heev rau kev xav tau hauv lub network thiab kev tsom xam kev hem thawj.
Tiv thaiv kev paim quav ntawm cov ntaub ntawv sab hauv
Los ntawm kev siv lub laj kab hluav taws xob los faib cov pab pawg sab hauv, cov network tseem ceeb ntawm cov pab pawg sab hauv tuaj yeem sib cais, yog li kev txwv qhov cuam tshuam ntawm qhov tseem ceeb hauv zos lossis rhiab teeb meem kev ruaj ntseg hauv lub network thoob ntiaj teb. Tsis tas li ntawd, kev ceev ntiag tug yog qhov teeb meem muaj kev txhawj xeeb loj rau sab hauv network. Cov ntsiab lus tsis tseem ceeb ntawm lub network sab hauv yuav muaj cov lus qhia txog kev ruaj ntseg, uas yuav ua rau muaj kev txaus siab ntawm cov neeg tuaj sab nraud, thiab tseem yuav nthuav tawm qee qhov kev ruaj ntseg hauv cov network sab hauv. Cov. Los ntawm kev siv lub foob pob hluav taws, cov kev pabcuam xws li Ntiv Tes, DNS thiab lwm yam kev pabcuam uas qhia tawm cov ntsiab lus sab hauv tuaj yeem muab zais. Ntiv tes qhia lub npe tso npe, lub npe tiag tiag, lub sijhawm nkag thaum kawg thiab lub plhaub hom ntawm txhua tus neeg siv ntawm tus tswv. Tab sis cov ntaub ntawv tso tawm los ntawm ntiv tes yog qhov yooj yim heev uas yuav kawm tau los ntawm kev tawm tsam. Tus tsim tawm tuaj yeem paub tias feem ntau siv lub kaw lus li cas, txawm tias muaj cov neeg siv nyob rau hauv lub vev xaib uas txuas rau hauv Is Taws Nem, seb lub system puas nyiam mloog thaum nws siv, thiab lwm yam. Lub foob pob hluav taws kuj tseem tuaj yeem thaiv DNS cov ntaub ntawv hais txog lub network sab hauv, yog li ntawd lub npe sau npe thiab tus IP chaw nyob ntawm tus tswv tsev yuav tsis to taub los ntawm ntiaj teb sab nraud. Ntxiv nrog rau qhov kev nyab xeeb muaj nuj nqi, lub foob pob hluav taws kuj txhawb VPN (Virtual Private Network), cov txheej txheem kev lag luam ntawm cov chaw ua lag luam' s sab hauv network nrog kev pabcuam hauv Is Taws Nem.
Nkag mus thiab kev ceeb toom cov xwm txheej
Txhua cov ntaub ntawv nkag mus thiab tawm hauv cov network yuav tsum dhau los ntawm firewall. Lub foob pob hluav taws sau nws hla lub cav, tuaj yeem muab cov ncauj lus kom ntxaws qhia ntawm kev siv network. Thaum muaj tej yam tsis txaus ntseeg tshwm sim, lub foob pob hluav taws tuaj yeem paub ntau dua thiab ceeb toom raws li lub tshuab, thiab muab cov ntaub ntawv ntawm seb lub network puas raug hem.
