Dab tsi yog qhov sib txawv ntawm passive network kais thiab nquag network coj mus rhaub?

A Network Kais, tseem hu ua cov kais ethernet, Tooj kais lossis cov ntaub ntawv coj mus siv, yog ib qho khoom siv siv hauv cov nom ethernet thiab saib xyuas cov tsheb network. Nws yog tsim los muab kev nkag mus rau cov ntaub ntawv ntws ntawm cov khoom siv network tsis muaj kev cuam tshuam lub lag luam network.

Lub hom phiaj tseem ceeb ntawm cov kais network yog los theej tawm cov pob ntawv network thiab xa lawv mus rau hauv cov cuab yeej soj ntsuam rau kev tsom xam lossis lwm lub hom phiaj. Nws yog feem ntau ntsia hauv-kab ntawm cov cuab yeej siv network, xws li hloov chaw lossis cov routers, thiab tuaj yeem txuas nrog cov cuab yeej soj ntsuam lossis tus kws tshaj lij network.

Network cov zaps tuaj hauv ob qho kev sib txawv thiab nquag hloov pauv:

1.Passive Network Taps: Passive network cov kais dej tsis tas yuav tsum muaj lub zog sab nraud thiab ua haujlwm ntawm kev sib cais los ntawm kev sib cais lossis cov luam tawm hauv lub network. Lawv siv cov txheej txheem zoo li kev ntsuas kho qhov muag lossis hluav taws xob kom tsim cov ntawv luam ntawm cov pob ntawv ntws los ntawm kev sib txuas. Cov theej tawm cov pob ntawv yog xa mus rau lub ntaus ntawv saib xyuas, thaum lub tsev qub khoom txuas ntxiv lawv qhov kis tau.

Cov kev sib faib ua ntu zus uas siv hauv cov tapeive network tuaj yeem sib txawv raws li cov ntawv thov tshwj xeeb thiab cov cai. Txawm li cas los xij, muaj ob peb lub txheem sib cais uas tau ntsib hauv kev xyaum:

50:50

Nov yog kev sib cais sib cais uas cov teeb meem kho kho kho kho qhov muag tau muab faib, nrog 50% mus rau lub network loj thiab 50% yog Tapping. Nws muab cov teeb liab sib npaug rau ob txoj kev.

70:30

Nyob rau hauv no piv, kwv yees li 70% ntawm lub teeb liab kho qhov muag tau hais rau lub network loj, thaum seem tshuav 30% yog Tapping. Nws muab ib feem loj ntawm lub teeb liab rau lub network loj thaum tseem tso cai rau kev saib xyuas lub peev xwm.

90:10

Qhov piv txwv no faib cov teeb liab kho qhov muag, nyob ib ncig ntawm 90%, rau lub network loj, nrog tsuas yog 10% yog tapped rau kev saib xyuas. Nws ua ntej cim qhia txog kev ncaj ncees rau lub network loj thaum muab qhov me me rau kev soj ntsuam.

:05

Zoo ib yam li 90:10 piv, qhov no cais tawm xa 95% ntawm lub teeb liab kho qhov muag mus rau lub network loj thiab cov peev txheej 5% rau kev soj ntsuam. Nws muaj kev cuam tshuam tsawg kawg rau cov teeb liab network tseem ceeb thaum muab ib feem me rau kev soj ntsuam lossis tshuaj xyuas cov kev xav tau.

 

 

 

 

2.Lub Network Taps: Cov kais dej num network, ntxiv rau cov pob ntawv luam tawm, suav nrog cov khoom siv ua kom muaj cov koom haum thiab cov Circuital los txhim kho lawv cov haujlwm. Lawv tuaj yeem muab cov txiaj ntsig zoo xws li cov kev lim tsheb ntau dua, kev tsom xam cov txheej txheem, thauj khoom sib npaug, lossis pob ntawv sib sau ua ke. Cov kais dej nquag feem ntau yuav tsum muaj zog sab nraud kom muaj zog cov haujlwm ntxiv no.

Network tau txais kev pab txhawb nqa ntau cov txheej txheem ethernet, suav nrog eternet, tcp / IP, vlan, thiab lwm tus. Lawv tuaj yeem ua kom sib txawv network tawm, xws li qis dua nrawm li 100 gbps lossis ntau dua, nyob ntawm tus qauv kais thiab nws lub peev xwm.

Cov tsheb khiav lag luam uas tau ntes tau rau kev saib xyuas network, daws teeb meem network, tshuaj xyuas kev ua phem, thiab ua cov network forensics. Cov kais dej feem ntau siv los ntawm cov thawj coj hauv network, thiab cov kws tshawb fawb kev nyab xeeb kom tau txais kev nkag siab rau kev coj tus cwj pwm thiab ua kom muaj kev ruaj ntseg, thiab ua raws li.
