Umahluko phakathi kweNethiwekhi ye-TAP kunye neNethiwekhi yokuTshintsha isibuko sesibuko

Ukujonga itrafikhi yothungelwano, njengohlalutyo lokuziphatha lomsebenzisi kwi-intanethi, ukujonga okungaqhelekanga kwetrafikhi, kunye nokujongwa kwesicelo sothungelwano, kufuneka uqokelele itrafikhi yenethiwekhi. Ukubamba itrafikhi yenethiwekhi kunokuba kungachanekanga. Enyanisweni, kufuneka ukhuphele i-traffic yenethiwekhi yangoku kwaye uyithumele kwisixhobo sokubeka iliso. I-Splitter yenethiwekhi, eyaziwa ngokuba yi-Network TAP. Iyawenza nje lo msebenzi. Makhe sijonge inkcazo ye-Network TAP:

I. Network Tap sisixhobo sehardware esibonelela ngendlela yokufikelela kwidata equkuqelayo kwinethiwekhi yekhompyuter.(isuka kwiwikipedia)

II. AItephu yeNethiwekhi, ekwaziwa ngokuba yiPort Access yoVavanyo, sisixhobo se-hardware esiplaga ngqo kwintambo yoMnatha kwaye ithumela iqhekeza lonxibelelwano lweNethiwekhi kwezinye izixhobo. Izahluli zenethiwekhi ziqhele ukusetyenziswa kwiinkqubo zokubona ukungena kwenethiwekhi (IPS), iziboni zenethiwekhi, kunye neeprofayili. Ukuphindaphinda unxibelelwano kwizixhobo zothungelwano ngoku ngokuqhelekileyo kwenziwa ngokutshintsha isihlalutyi sezibuko (i-span port), eyaziwa ngokuba sisibuko sesibuko kuthungelwano lokutshintsha.

III. Iitephu zeNethiwekhi zisetyenziselwa ukwenza amazibuko ofikelelo ngokusisigxina ukwenzela uqwalaselo lokwenziwa. Itephu, okanye iPort yokuFikelela kuVavanyo, inokusekwa phakathi kwazo naziphi na izixhobo ezibini zenethiwekhi, ezifana nokutshintsha, iirutha kunye neendonga zomlilo. Inokusebenza njengechweba lokufikelela kwisixhobo sokubeka iliso esisetyenziselwa ukuqokelela idatha ye-in-line, kubandakanywa nenkqubo yokufumanisa i-Intrusion, inkqubo yokukhusela i-Intrusion esetyenziswe kwimodi yokwenziwa, abahlalutyi beprotocol kunye nezixhobo zokubeka iliso ezikude. (ukusuka kwi-NetOptics).

Ukusuka kwezi nkcazo zintathu zingentla, sinokuzoba iimpawu ezininzi ze-Network TAP: i-hardware, i-inline, i-transparent

Nanku ujongo kwezi mpawu:

1. Yinxalenye ezimeleyo ye-hardware, kwaye ngenxa yoko, ayinayo nayiphi na impembelelo kumthwalo wezixhobo zothungelwano ezikhoyo, ezineenzuzo ezinkulu ngaphezu kwesibuko sezibuko.

2. Sisixhobo sangaphakathi. Ukubeka nje, kufuneka idibaniswe nenethiwekhi, enokuqondwa. Nangona kunjalo, oku kunento engalunganga yokwazisa inqaku lokungaphumeleli, kwaye ngenxa yokuba sisixhobo se-intanethi, inethiwekhi yangoku kufuneka iphazamiseke ngexesha lokuthunyelwa, kuxhomekeke apho isetyenziswe khona.

3. I-transparent ibhekisa kwisalathisi kuthungelwano lwangoku. Ukufikelela kwinethiwekhi emva kwe-shunt, inethiwekhi yangoku yazo zonke izixhobo, ayinayo nayiphi na impembelelo, kubo icacile ngokupheleleyo, ngokuqinisekileyo, iqulethe i-network shunt thumela i-traffic ukujonga izixhobo, isixhobo sokubeka iliso kuthungelwano siselubala, njengoko ukuba ukwindlela entsha yokufikelela kwisixhobo sombane esitsha, kwezinye izixhobo ezikhoyo, Akukho nto yenzekayo, kubandakanywa xa ususa isixhobo sombane kwaye ngequbuliso ukhumbule umbongo othi, “Zulisa umkhono wakho hayi ilifu”......

Abantu abaninzi baqhelene ne-port mirroring. Ewe, isibuko sezibuko sinokufikelela kwisiphumo esifanayo. Nalu uthelekiso phakathi kweTephu zeNethiwekhi/Iziphambukisi kunye neSibuko sesibuko:

1. Njengoko izibuko lokutshintsha ngokwalo liza kuhluza iipakethe ezithile zempazamo kunye neepakethi ezinobungakanani obuncinci kakhulu, isibuko sesibuko asinakuqinisekisa ukuba zonke izithuthi zinokufumaneka. Nangona kunjalo, i-shunter iqinisekisa ingqibelelo yedatha kuba "ikhutshelwe" ngokupheleleyo kwinqanaba lomzimba

2. Ngokubhekiselele ekusebenzeni kwexesha lokwenyani, kwezinye izitshixo ezisezantsi, isibuko sesibuko sinokuzisa ukulibaziseka xa sikhuphela i-traffic kwizibuko ezibonisa izibuko, kwaye yazisa ukulibaziseka xa ikopisha i-10/100m kumazibuko e-GIGA.

3. Isibuko sesibuko sifuna ukuba i-bandwidth yezibuko ebonisiweyo ibe nkulu okanye ilingane nesamba se-bandwidth yazo zonke izibuko ezibonisiweyo. Nangona kunjalo, le mfuno ayinakuhlangatyezwa zizo zonke iiswitshi

4. Isibuko sezibuko kufuneka siqwalaselwe kwiswitshi. Nje ukuba iindawo eziza kubekwa esweni zifuna ukulungiswa, utshintsho kufuneka luphinde luqwalaselwe.
