Ukuze uqaphe ithrafikhi yenethiwekhi, njengokuhlaziywa kokuziphatha ku-inthanethi komsebenzisi, ukugadwa kwethrafikhi okungavamile, nokuqapha kohlelo lokusebenza lwenethiwekhi, udinga ukuqoqa ithrafikhi yenethiwekhi.Ukuthwebula ithrafikhi yenethiwekhi kungenzeka kungalungile.Eqinisweni, udinga ukukopisha ithrafikhi yenethiwekhi yamanje futhi uyithumele kudivayisi yokuqapha.I-Splitter yenethiwekhi, eyaziwa nangokuthi i-Network TAP.Iyawenza lo msebenzi nje.Ake sibheke incazelo ye-Network TAP:
I. I-Network Tap iyisisetshenziswa sehadiwe esihlinzeka ngendlela yokufinyelela idatha egeleza kunethiwekhi yekhompiyutha.(kusuka ku-wikipedia)
II.AI-Network Tap, eyaziwa nangokuthi Imbobo Yokufinyelela Kokuhlola, idivayisi yehadiwe exhuma ngokuqondile kukhebuli Yenethiwekhi bese ithumela ucezu Lokuxhumana Kwenethiwekhi kwamanye amadivayisi.Izihlukanisi zenethiwekhi zivame ukusetshenziswa ezinhlelweni zokuthola ukungena kwenethiwekhi (IPS), izitholi zenethiwekhi, namaphrofayili.Ukuphindaphinda ukuxhumana kumadivayisi enethiwekhi manje ngokuvamile kwenziwa ngokusebenzisa isihlaziyi sembobo esishintshayo (imbobo ye-span), eyaziwa nangokuthi i-port mirroring ekushintsheni kwenethiwekhi.
III.I-Network Taps isetshenziselwa ukudala izimbobo zokufinyelela unomphela zokuqapha okungenzi lutho.Ukuthepha, noma Imbobo yokufinyelela yokuhlola, ingasethwa phakathi kwanoma yimaphi amadivayisi amabili enethiwekhi, njengamaswishi, amarutha nama-firewall.Ingasebenza njengembobo yokufinyelela yedivayisi yokuqapha esetshenziselwa ukuqoqa idatha esemgqeni, okuhlanganisa isistimu yokutholwa kwe-Intrusion, isistimu yokuvimbela ukungena efakwe kumodi yokungenzi lutho, abahlaziyi bephrothokholi namathuluzi okuqapha akude.(kusuka ku-NetOptics).
Kusukela kulezi zincazelo ezintathu ezingenhla, singadweba izici ezimbalwa ze-Network TAP: ihadiwe, i-inline, i-transparent
Nakhu ukubheka lezi zici:
1. Iyingxenye ezimele ye-hardware, futhi ngenxa yalokhu, ayinawo umthelela emthwalweni wamadivayisi enethiwekhi akhona, anezinzuzo ezinhle ngaphezu kwe-port mirroring.
2. Kuyinto in-line idivayisi.Kalula nje, idinga ukuxhunywa kunethiwekhi, engaqondwa.Kodwa-ke, lokhu nakho kunobubi bokwethula iphuzu lokwehluleka, futhi ngenxa yokuthi kuyidivayisi eku-inthanethi, inethiwekhi yamanje idinga ukuphazanyiswa ngesikhathi sokuphakelwa, kuye ngokuthi isetshenziswa kuphi.
3. I-Transparent ibhekisela kusikhombisi senethiwekhi yamanje.Finyelela amanethiwekhi ngemuva kwe-shunt, inethiwekhi yamanje yazo zonke izinto zokusebenza, ayinawo umthelela, kubo isobala ngokuphelele, yebo, iqukethe ne-network shunt thumela ithrafikhi yokuqapha imishini, idivayisi yokuqapha inethiwekhi isobala, kunjengoba uma usesimweni esisha sokufinyelela endaweni entsha kagesi, kwezinye izinto zikagesi ezikhona, Akukho okwenzekayo, okuhlanganisa lapho ekugcineni ususa umshini futhi kungazelelwe ukhumbule inkondlo ethi, "Nyakazisa umkhono wakho hhayi ifu"......
Abantu abaningi bajwayelene ne-port mirroring.Yebo, i-port mirroring nayo ingafinyelela umphumela ofanayo.Nasi ukuqhathanisa phakathi kwe-Network Taps/Diverters kanye ne-Port Mirroring:
1. Njengoba imbobo yeswishi ngokwayo izohlunga amanye amaphakethe amaphutha namaphakethe anosayizi omncane kakhulu, ukwenza isibuko sembobo akukwazi ukuqinisekisa ukuthi yonke ithrafikhi ingatholwa.Nokho, i-shunter iqinisekisa ubuqotho bedatha ngoba "ikopishwe" ngokuphelele kusendlalelo esibonakalayo
2. Mayelana nokusebenza kwesikhathi sangempela, kwamanye amaswishi asezingeni eliphansi, isibuko sembobo singase sethule ukubambezeleka lapho sikopisha ithrafikhi ezindaweni ezibukwayo, futhi sethula ukubambezeleka lapho sikopisha izimbobo ezingu-10/100m ezimbobeni ze-GIGA.
3. Ukwenza isibuko sembobo kudinga ukuthi umkhawulokudonsa wembobo esibukweni ube mkhulu noma ulingane nesamba somkhawulokudonsa wazo zonke izimbobo ezinezibuko.Nokho, le mfuneko ingase ingafinyelelwa yiwo wonke amaswishi
4. Isibuko sembobo sidinga ukulungiselelwa kuswishi.Lapho izindawo ezizogadwa zidinga ukulungiswa, iswishi idinga ukulungiswa kabusha.
