Ndizera ko uzi ingorane ziri hagati ya Network Tap (Test Access Point) na switch port analyzer (SPAN port) mu rwego rwo kugenzura Network. Zombi zifite ubushobozi bwo kwerekana urujya n'uruza rw'abantu kuri network no kuyohereza ku bikoresho by'umutekano bitari mu itsinda nka sisitemu zo kumenya kwinjira, network loggers, cyangwa network analyzers. Span ports zishyirwaho kuri network enterprise switches zifite imikorere yo kureba port. Ni port yihariye kuri switch icungwa ifata kopi y'urujya n'uruza rw'abantu kuri network kuva kuri switch kugira ngo yoherezwe ku bikoresho by'umutekano. TAP, ku rundi ruhande, ni igikoresho gikwirakwiza urujya n'uruza rw'abantu kuva kuri network kugera ku gikoresho cy'umutekano. TAP yakira urujya n'uruza rw'abantu mu byerekezo byombi mu gihe nyacyo no ku murongo utandukanye.
Izi ni zo nyungu eshanu z'ingenzi za TAP binyuze kuri port ya SPAN:
1. TAP ifata buri paki imwe!
Span Ikuraho amapaki n'amapaki byangiritse bito ugereranyije n'ingano ntoya. Kubwibyo, ibikoresho by'umutekano ntibishobora kwakira abantu bose basura urubuga kuko amapaki ya span aha umwanya munini abantu basura urubuga. Byongeye kandi, abantu basura urubuga rwa RX na TX bahurira kuri port imwe, bityo amapaki ashobora gutabwa. TAP ifata abantu bose basura urubuga kuri buri port, harimo n'amakosa ya port.
2. Igisubizo kidakora cyane, nta miterere ya IP cyangwa umuriro ukenewe
Passive TAP ikoreshwa cyane cyane mu miyoboro ya fiber optique. Muri passive TAP, yakira urujya n'uruza rw'abantu ruturutse mu byerekezo byombi by'umuyoboro kandi igacamo urumuri rwinjiye ku buryo 100% by'urujya n'uruza rw'abantu rugaragara ku gikoresho cyo kugenzura. Passive TAP ntisaba amashanyarazi. Kubera iyo mpamvu, bongeraho urwego rwo kugabanya umubare w'amashanyarazi, ntibasaba gusana cyane, kandi bakagabanya ikiguzi muri rusange. Niba uteganya kugenzura urujya n'uruza rw'amashanyarazi ya Ethernet, ugomba gukoresha active TAP. Active TAP isaba amashanyarazi, ariko Active TAP ya Niagra irimo ikoranabuhanga ririnda kwangirika rikuraho ibyago byo guhungabana kwa serivisi mu gihe habayeho ibura ry'amashanyarazi.
3. Nta gutakaza ipaki
Network TAP igenzura impande zombi z'umuyoboro kugira ngo ibone 100% urujya n'uruza rw'imiyoboro y'itumanaho. TAP ntabwo ijugunya paki iyo ari yo yose, uko bandwidth yayo yaba iri kose.
4. Bikwiriye gukoreshwa mu buryo buri hagati kugeza ku bwinshi
Umuyoboro wa SPAN ntushobora gutunganya imiyoboro ya interineti ikoreshwa cyane hatabayeho gusohora paki. Kubwibyo, TAP ya network irakenewe muri ibi bihe. Iyo umuyoboro wa SPAN uva kuri SPAN urenze uwo wakirwa, umuyoboro wa SPAN uba urenze urugero kandi ugahatirwa kujugunya paki. Kugira ngo ufate 10Gb y'umuyoboro wa interineti w'inzira ebyiri, umuyoboro wa SPAN ukeneye 20Gb y'ubushobozi, kandi TAP ya Network ya 10Gb izabasha gufata 10Gb y'ubushobozi bwose.
5. TAP Yemerera abantu bose banyura, harimo na VLAN tags
Muri rusange, imiyoboro ya "span ports" ntiyemerera ko label za VLAN zinyura, ibyo bigatuma bigorana kubona ibibazo bya VLAN no guteza ibibazo bitari byo. TAP yirinda ibyo bibazo ireka abantu bose bakanyura.
