Kodi mudamvapo za kulumikizidwa kwa netiweki? Ngati mumagwira ntchito yokhudzana ndi maukonde kapena chitetezo cha pa intaneti, mwina mukudziwa bwino chipangizochi. Koma kwa iwo omwe sadziwa, chingakhale chinsinsi.
Masiku ano, chitetezo cha maukonde ndi chofunika kwambiri kuposa kale lonse. Makampani ndi mabungwe amadalira maukonde awo kuti asunge zambiri zachinsinsi komanso kulankhulana ndi makasitomala ndi anzawo. Kodi angatsimikizire bwanji kuti maukonde awo ndi otetezeka komanso opanda chilolezo?
Nkhaniyi ifufuza tanthauzo la netiweki, momwe imagwirira ntchito, komanso chifukwa chake ndi chida chofunikira kwambiri pachitetezo cha netiweki. Tiyeni tiphunzire zambiri za chipangizo champhamvu ichi.
Kodi Network TAP (Terminal Access Point) ndi chiyani?
Ma Network TAP ndi ofunikira kuti network igwire bwino ntchito komanso motetezeka. Amapereka njira zowunikira, kusanthula, kutsatira, komanso kuteteza zomangamanga za network. Ma Network TAP amapanga "kopi" ya kuchuluka kwa magalimoto, zomwe zimathandiza kuti zipangizo zosiyanasiyana zowunikira zipeze chidziwitsocho popanda kusokoneza kayendedwe koyambirira ka ma data.
Zipangizozi zili pamalo abwino kwambiri pa netiweki yonse kuti zitsimikizire kuti zikuyang'aniridwa bwino kwambiri.
Mabungwe amatha kukhazikitsa ma TAP a netiweki pamalo omwe akuona kuti ayenera kuwonedwa, kuphatikiza koma osati kokha malo osonkhanitsira deta, kusanthula, kuyang'anira zonse, kapena zofunika kwambiri monga kuzindikira kulowerera.
Chipangizo cha TAP cha netiweki sichisintha momwe paketi iliyonse ilili pa netiweki yogwira ntchito; chimangopanga kopi ya paketi iliyonse yotumizidwa kuti itumizidwe kudzera mu mawonekedwe ake olumikizidwa ku zida zowunikira kapena mapulogalamu.
Njira yokopera imachitika popanda kupsinjika kwa mphamvu ya ntchito chifukwa sizimasokoneza ntchito zachizolowezi mu waya mutatha kugogoda. Chifukwa chake, zimathandiza mabungwe kukhala ndi chitetezo chowonjezera pamene akupeza ndikuchenjeza zochitika zokayikitsa pa netiweki yawo ndikuyang'anira mavuto ochedwa omwe angachitike nthawi yomwe amagwiritsidwa ntchito kwambiri.
Kodi Network TAP Imagwira Ntchito Bwanji?
Ma Network TAP ndi zida zapamwamba zomwe zimathandiza oyang'anira kuwunika momwe netiweki yawo yonse imagwirira ntchito popanda kusokoneza magwiridwe antchito ake. Ndi zida zakunja zomwe zimagwiritsidwa ntchito kuyang'anira zochita za ogwiritsa ntchito, kuzindikira magalimoto oyipa komanso kuteteza chitetezo cha netiweki polola kusanthula mozama deta yomwe ikuyenda ndi kutuluka. Ma Network TAP amalumikiza gawo lenileni lomwe mapaketi amadutsa pa zingwe ndi ma switch ndi zigawo zapamwamba zomwe mapulogalamu amakhala.
Network TAP imagwira ntchito ngati chosinthira cha passive port chomwe chimatsegula ma port awiri enieni kuti agwire magalimoto onse obwera ndi otuluka kuchokera ku ma network aliwonse omwe amadutsamo. Chipangizochi chapangidwa kuti chisasokoneze 100%, kotero ngakhale chimalola kuyang'anira, kununkhiza, ndi kusefa mapaketi a data, Network TAPs sizimasokoneza kapena kusokoneza magwiridwe antchito a netiweki yanu mwanjira iliyonse.
Kuphatikiza apo, amagwira ntchito ngati njira zotumizira deta yoyenera ku malo owunikira omwe adasankhidwa; izi zikutanthauza kuti sangathe kusanthula kapena kuwunika zomwe asonkhanitsa - zomwe zimafuna chida china chachitatu kuti athe kutero. Izi zimathandiza oyang'anira kuwongolera molondola komanso kusinthasintha pankhani yosintha momwe angagwiritsire ntchito bwino ma Network TAP awo pamene akupitiliza kugwira ntchito mosalekeza pa netiweki yawo yonse.
N’chifukwa Chiyani Tikufunika Network TAP?
Ma Network TAP amapereka maziko okhala ndi njira yowunikira komanso yowunikira bwino pa netiweki iliyonse. Mwa kugwiritsa ntchito njira yolumikizirana, amatha kuzindikira deta yomwe ili pa waya kuti ifalitsidwe ku njira zina zachitetezo kapena zowunikira. Gawo lofunika kwambiri la mawonekedwe a netiweki limatsimikizira kuti deta yonse yomwe ili pamzerewu siiphonya pamene magalimoto akudutsa, zomwe zikutanthauza kuti palibe mapaketi omwe amatayidwa.
Popanda ma TAP, netiweki singathe kuyang'aniridwa ndi kuyendetsedwa mokwanira. Oyang'anira IT amatha kuyang'anira modalirika kuti awone zoopsa kapena kupeza chidziwitso chokwanira cha ma netiweki awo omwe makonzedwe akunja kwa gulu angabisike mwa kupereka mwayi wopeza zambiri zonse za magalimoto.
Motero, makope enieni a mauthenga obwera ndi otuluka amaperekedwa, zomwe zimathandiza mabungwe kufufuza ndikuchitapo kanthu mwachangu pazochitika zilizonse zokayikitsa zomwe angakumane nazo. Kuti maukonde a mabungwe akhale otetezeka komanso odalirika m'nthawi yamakono yaupandu wa pa intaneti, kugwiritsa ntchito TAP ya netiweki kuyenera kuonedwa ngati kofunikira.
Mitundu ya ma TAP a Network ndi Momwe Amagwirira Ntchito?
Ponena za kupeza ndi kuyang'anira kuchuluka kwa magalimoto pa netiweki, pali mitundu iwiri yayikulu ya ma TAP - Passive TAPs ndi Active TAPs. Onsewa amapereka njira yosavuta komanso yotetezeka yopezera deta kuchokera pa netiweki popanda kusokoneza magwiridwe antchito kapena kuwonjezera kuchedwa kwina ku dongosolo.
TAP yopanda ntchito imagwira ntchito poyang'ana zizindikiro zamagetsi zomwe zimadutsa mu chingwe cholumikizira pakati pa zipangizo ziwiri, monga pakati pa makompyuta ndi ma seva. Imapereka malo olumikizirana omwe amalola gwero lakunja, monga rauta kapena sniffer, kuti lifike pakuyenda kwa chizindikirocho pamene likudutsabe komwe likupita koyambirira popanda kusintha. Mtundu uwu wa TAP umagwiritsidwa ntchito poyang'anira zochitika kapena chidziwitso chokhudza nthawi pakati pa mfundo ziwiri.
<Ma TAP a Network Ogwira Ntchito>
TAP yogwira ntchito imagwira ntchito mofanana ndi ina yake yopanda ntchito koma ili ndi gawo lina mu ndondomekoyi - kuyambitsa njira yobwezeretsa chizindikiro. Pogwiritsa ntchito njira yobwezeretsa chizindikiro, TAP yogwira ntchito imatsimikizira kuti chidziwitso chikhoza kuyang'aniridwa molondola chisanapitirire patsogolo.
Izi zimapereka zotsatira zofanana ngakhale ndi ma voltage osiyanasiyana ochokera kuzinthu zina zolumikizidwa mu unyolo. Kuphatikiza apo, mtundu uwu wa TAP umathandizira ma transmissions pamalo aliwonse ofunikira kuti akonze nthawi yogwirira ntchito.
Kodi ubwino wa Network TAP ndi wotani?
Ma Network TAP akhala otchuka kwambiri m'zaka zaposachedwa pamene mabungwe amayesetsa kuwonjezera chitetezo chawo ndikuonetsetsa kuti ma network awo akuyenda bwino nthawi zonse. Pokhala ndi luso loyang'anira ma doko angapo nthawi imodzi, Network TAPs imapereka yankho labwino komanso lotsika mtengo kwa mabungwe omwe akufuna kuwona bwino zomwe zikuchitika pa ma network awo.
Kuphatikiza apo, ndi zinthu monga chitetezo cha bypass, kuphatikiza mapaketi, ndi kuthekera kosefera, Network TAPs imathanso kupatsa mabungwe njira yotetezeka yosungira maukonde awo ndikuyankha mwachangu ku ziwopsezo zomwe zingachitike.
Network TAPs imapatsa mabungwe maubwino angapo, monga:
- Kuwonjezeka kwa kuwonekera kwa kuchuluka kwa magalimoto omwe amalowa pa netiweki.
- Kulimbitsa chitetezo ndi kutsatira malamulo.
- Kuchepetsa nthawi yopuma popereka chidziwitso chokwanira pa zomwe zimayambitsa mavuto aliwonse.
- Kuwonjezeka kwa kupezeka kwa netiweki polola kuti pakhale kuthekera kowunikira zinthu ziwiri.
- Kuchepetsa mtengo wa umwini chifukwa nthawi zambiri zimakhala zotsika mtengo kuposa njira zina zothetsera mavuto.
Galasi la Network TAP vs. SPAN Port (Kodi Mungajambule Bwanji Magulu a Anthu pa Network? Network Tap vs Port Mirror?):
Madoko a Network TAPs (Traffic Access Points) ndi SPAN (Switched Port Analyzer) ndi zida ziwiri zofunika kwambiri poyang'anira kuchuluka kwa magalimoto pa intaneti. Ngakhale kuti zonsezi zimathandiza kuti ma network aziwoneka bwino, kusiyana pang'ono pakati pa awiriwa kuyenera kumveka kuti kudziwike komwe kuli koyenera kwambiri pazochitika zinazake.
Network TAP ndi chipangizo chakunja chomwe chimalumikizana ndi malo olumikizirana pakati pa zipangizo ziwiri zomwe zimalola kuyang'anira mauthenga omwe akudutsamo. Sichisintha kapena kusokoneza deta yomwe ikutumizidwa ndipo sichidalira switch yomwe yakonzedwa kuti igwiritse ntchito.
Kumbali inayi, doko la SPAN ndi mtundu wapadera wa doko losinthira pomwe magalimoto olowa ndi otuluka amawonetsedwa ku doko lina kuti aziyang'anira. Madoko a SPAN amatha kukhala ovuta kuwakonza kuposa ma Network TAP, komanso amafuna kugwiritsa ntchito switch kuti igwiritsidwe ntchito.
Chifukwa chake, ma Network TAP ndi oyenera kwambiri pazochitika zomwe zimafuna kuwonekera bwino kwambiri, pomwe ma SPAN ports ndi abwino kwambiri pa ntchito zosavuta zowunikira.
