Kodi munayamba mwamvapo za tap ya netiweki? Ngati mumagwira ntchito pamanetiweki kapena cybersecurity, mutha kuchidziwa bwino chipangizochi. Koma kwa iwo amene sali, zikhoza kukhala chinsinsi.
M'dziko lamakono, chitetezo cha intaneti ndichofunika kwambiri kuposa kale lonse. Makampani ndi mabungwe amadalira ma netiweki awo kuti asunge zinthu zachinsinsi komanso kulumikizana ndi makasitomala ndi anzawo. Kodi angatsimikizire bwanji kuti maukonde awo ndi otetezeka komanso opanda chilolezo?
Nkhaniyi iwunikanso kuti tap ya netiweki ndi chiyani, momwe imagwirira ntchito, komanso chifukwa chake ili chida chofunikira pachitetezo chamaneti. Choncho tiyeni tilowe mkati ndi kuphunzira zambiri za chipangizo champhamvu chimenechi.
Kodi Network TAP (Terminal Access Point) ndi chiyani?
Ma TAP a Network ndi ofunikira kuti ma network achite bwino komanso otetezeka. Amapereka njira zowunikira, kusanthula, kutsatira, ndi kuteteza ma network. Network TAPs imapanga "kopi" ya magalimoto, zomwe zimathandiza kuti zipangizo zosiyanasiyana zowunikira zizitha kupeza chidziwitsocho popanda kusokoneza kayendedwe koyambirira kwa mapaketi a data.
Zipangizozi zimayikidwa bwino pamakina onse a netiweki kuti zitsimikizire kuwunikira kothandiza kwambiri.
Mabungwe amatha kukhazikitsa ma TAP a netiweki pamalo omwe akuwona kuti akuyenera kuwonedwa, kuphatikiza koma osangokhala ndi malo osonkhanitsira deta, kusanthula, kuyang'anira wamba, kapena zovuta zina monga kuzindikira kulowerera.
Chipangizo cha TAP cha netiweki sichisintha zomwe zilipo paketi iliyonse pa netiweki yogwira; imangopanga chofanana cha paketi iliyonse yotumizidwa kuti itumizidwe kudzera mu mawonekedwe ake olumikizidwa ndi zida zowunikira kapena mapulogalamu.
Kukopera kumachitidwa popanda kugogomezera kuchuluka kwa magwiridwe antchito chifukwa sikusokoneza magwiridwe antchito muwaya mukatha kumaliza. Chifukwa chake, kupangitsa mabungwe kukhala ndi chitetezo chowonjezera pomwe akuwona ndi kuchenjeza zochitika zokayikitsa pamanetiweki awo ndikuyang'anira zovuta za latency zomwe zitha kuchitika panthawi yogwiritsa ntchito kwambiri.
Kodi Network TAP Imagwira Ntchito Motani?
Network TAPs ndi zida zamakono zomwe zimathandiza olamulira kuti awone momwe maukonde awo amagwirira ntchito popanda kusokoneza ntchito yake. Ndizida zakunja zomwe zimagwiritsidwa ntchito poyang'anira ntchito za ogwiritsa ntchito, kuzindikira magalimoto oyipa ndikuteteza chitetezo cha intaneti polola kusanthula mozama kwa deta yomwe ikuyenda ndi kutulukamo. Ma Network TAP amatsekereza gawo lomwe mapaketi amayenda pazingwe ndi ma switch komanso zigawo zapamwamba pomwe mapulogalamu amakhala.
Network TAP imagwira ntchito ngati chosinthira doko chomwe chimatsegula madoko awiri kuti agwire magalimoto onse omwe akubwera ndi otuluka kuchokera pamalumikizidwe aliwonse omwe amadutsamo. Chipangizochi chapangidwa kuti chikhale chosasokoneza 100%, kotero kuti chimapangitsa kuyang'anitsitsa, kununkhiza, ndi kusefa mapaketi a data, Network TAPs samasokoneza kapena kusokoneza machitidwe a intaneti yanu mwanjira iliyonse.
Kuphatikiza apo, amangokhala ngati njira zotumizira deta yoyenera kumalo owunikira; izi zikutanthauza kuti sangathe kusanthula kapena kuwunika zomwe amasonkhanitsa - kufuna chida china cha chipani chachitatu kuti athe kutero. Izi zimathandiza oyang'anira kuwongolera bwino komanso kusinthasintha zikafika pakukonza momwe angagwiritsire ntchito bwino ma Network TAPs awo pomwe akupitilizabe kugwira ntchito mosadodometsedwa pa maukonde awo onse.
Chifukwa Chiyani Timafunikira Network TAP?
Ma Network TAPs amapereka maziko oti mukhale ndi mawonekedwe owoneka bwino komanso olimba pamaneti aliwonse. Pogwiritsa ntchito njira yolankhulirana, amatha kuzindikira deta pawaya kuti athe kutumizidwa kuzinthu zina zachitetezo kapena zowunikira. Chigawo chofunika kwambiri cha mawonekedwe a intaneti chimatsimikizira kuti zonse zomwe zilipo pamzerewu sizikuphonya pamene magalimoto akudutsa, kutanthauza kuti palibe mapaketi omwe amagwetsedwa.
Popanda ma TAPs, netiweki singayang'anitsidwe ndikuyendetsedwa bwino. Oyang'anira IT atha kuyang'anira zowopseza kapena kudziwa bwino maukonde awo omwe masinthidwe akunja angabisike popereka mwayi wodziwa zambiri zamagalimoto.
Mwakutero, kopi yeniyeni ya mauthenga omwe akubwera ndi otuluka amaperekedwa, kulola mabungwe kufufuza ndi kuchitapo kanthu mwamsanga pazochitika zilizonse zokayikitsa zomwe angakumane nazo. Kuti maukonde a mabungwe akhale otetezeka komanso odalirika m'nthawi yamakono ya umbanda wa pa intaneti, kugwiritsa ntchito netiweki TAP kuyenera kuonedwa ngati kovomerezeka.
Mitundu ya Network TAPs ndi Momwe Amagwirira Ntchito?
Pankhani yopeza ndikuwunika kuchuluka kwa magalimoto pamaneti, pali mitundu iwiri yayikulu ya TAPs - Passive TAPs ndi Active TAPs. Onsewa amapereka njira yabwino komanso yotetezeka yopezera deta kuchokera pa intaneti popanda kusokoneza ntchito kapena kuwonjezera latency yowonjezera ku dongosolo.
<Zithunzi za Passive Network TAPs>
TAP yosagwira ntchito imagwira ntchito poyang'ana ma siginecha amagetsi omwe amadutsa ulalo wanthawi zonse wolunjika-ku-point pakati pa zida ziwiri, monga pakati pa makompyuta ndi maseva. Amapereka malo olumikizira omwe amalola gwero lakunja, monga rauta kapena sniffer, kuti azitha kulumikizana ndi ma siginecha pomwe akudutsa komwe akupita kosasinthika. TAP yamtunduwu imagwiritsidwa ntchito poyang'anira zochitika zokhudzana ndi nthawi kapena chidziwitso pakati pa mfundo ziwiri.
TAP yogwira ntchito imagwira ntchito ngati mnzake wongokhala koma ili ndi gawo lowonjezerapo - kuyambitsa mawonekedwe osinthika. Pogwiritsa ntchito kusinthika kwazizindikiro, TAP yogwira imawonetsetsa kuti chidziwitso chitha kuyang'aniridwa bwino chisanapitirire pamzere.
Izi zimapereka zotsatira zofananira ngakhale ndi ma voliyumu osiyanasiyana ochokera kumagwero ena olumikizidwa ndi tcheni. Kuphatikiza apo, mtundu uwu wa TAP umafulumizitsa kutumiza kulikonse pamalo aliwonse ofunikira kuti muwonjezere nthawi yogwira ntchito.
Kodi Ubwino Wa Network TAP Ndi Chiyani?
Ma Network TAP adziwika kwambiri m'zaka zaposachedwa pomwe mabungwe amayesetsa kuwonjezera njira zawo zachitetezo ndikuwonetsetsa kuti maukonde awo akuyenda bwino nthawi zonse. Ndi kuthekera koyang'anira madoko angapo nthawi imodzi, Network TAPs imapereka njira yabwino komanso yotsika mtengo kwa mabungwe omwe akufuna kuwona bwino zomwe zikuchitika pamanetiweki awo.
Kuonjezera apo, ndi zinthu monga chitetezo chodutsa, kusonkhanitsa paketi, ndi zosefera, Network TAPs imathanso kupatsa mabungwe njira yotetezeka yosungira maukonde awo ndikuyankha mwachangu kuopseza komwe kungachitike.
Network TAPs imapatsa mabungwe maubwino angapo, monga:
- Kuwoneka kowonjezereka mumayendedwe amtaneti.
- Kupititsa patsogolo chitetezo ndi kutsata.
- Kuchepetsa nthawi yopuma popereka chidziwitso chochulukirapo pazomwe zimayambitsa zovuta zilizonse.
- Kuchulukitsa kupezeka kwa netiweki polola kuti pakhale kuwunikira kwathunthu kwa duplex.
- Kuchepetsa mtengo wa umwini chifukwa nthawi zambiri amakhala otsika mtengo kuposa njira zina.
Network TAP vs. SPAN Port Mirror(Momwe mungajambulire Network Traffic? Network Tap vs Port Mirror?):
Ma Network TAPs (Traffic Access Points) ndi madoko a SPAN (Switched Port Analyzer) ndi zida ziwiri zofunika pakuwunika kuchuluka kwa maukonde. Ngakhale kuti onsewa akuwonetsa ma netiweki, kusiyana kobisika pakati pa ziwirizi kuyenera kumveka kuti mudziwe chomwe chili choyenera pazochitika zinazake.
Network TAP ndi chipangizo chakunja chomwe chimalumikizana mpaka kulumikiza zida ziwiri zomwe zimalola kuyang'anira kulumikizana komwe kumadutsamo. Sichimasintha kapena kusokoneza deta yomwe ikufalitsidwa ndipo sichidalira kusintha komwe kumapangidwira kuti mugwiritse ntchito.
Kumbali ina, doko la SPAN ndi mtundu wapadera wa doko losinthira momwe magalimoto obwera ndi otuluka amawonetsedwa kudoko lina kuti awonere. Madoko a SPAN amatha kukhala ovuta kuwongolera kuposa Network TAPs, komanso amafuna kugwiritsa ntchito chosinthira kuti chigwiritsidwe ntchito.
Chifukwa chake, ma TAP a Network ndi oyenera pazochitika zomwe zimafuna kuti ziwoneke bwino, pomwe madoko a SPAN ndi abwino kwambiri pantchito zowunikira.
