Wakambonzwa nezve network tap? Kana iwe ukashanda mumunda wetiweki kana cybersecurity, unogona kunge uchijairana nemudziyo uyu. Asi kune avo vasiri, zvinogona kuva zvakavanzika.
Munyika yanhasi, kuchengetedzwa kwetiweki kwakakosha kupfuura nakare kose. Makambani nemasangano anovimba netiweki yavo kuchengetedza data rakadzama uye kutaurirana nevatengi uye vanobatika. Vangaite sei kuti network yavo yakachengeteka uye isina mvumo yekuwana?
Ichi chinyorwa chichaongorora kuti network tapi chii, kuti inoshanda sei, uye nei chiri chinhu chakakosha chekuchengetedza network. Saka ngatinyure mukati uye tidzidze zvakawanda nezve mudziyo une simba uyu.
Chii chinonzi Network TAP (Terminal Access Point)?
Network TAPs dzakakosha pakubudirira uye kuchengetedzwa kwetiweki kuita. Ivo vanopa nzira dzekutarisa, kuongorora, kutevedzera, uye kuchengetedza network network. Network TAPs inogadzira "kopi" yetraffic, ichigonesa akasiyana ekutarisa maturusi kuwana ruzivo irworwo pasina kukanganisa kuyerera kwekutanga kwemapaketi edata.
Zvishandiso izvi zvakamisikidzwa zvine hungwaru mukati metiweki zvivakwa kuti ive nechokwadi chekutarisa kwakanyanya kunogoneka.
Masangano anogona kuisa maTAP etiweki panzvimbo dzavanofunga kuti dzinofanirwa kucherechedzwa, kusanganisira asi kwete kuganhurirwa kunzvimbo dzekuunganidza data, kuongorora, kutarisisa kwese, kana zvakanyanya kunetsa sekuonekwa kwekupinda.
Iyo network TAP mudziyo haishandure mamiriro aripo echero packet pane inoshanda network; inongogadzira replica yepakiti yega yega inotumirwa kuitira kuti ikwanise kuendeswa kuburikidza neyayo interface yakabatana neyekutarisa zvishandiso kana zvirongwa.
Maitiro ekukopa anoitwa pasina kushungurudza mashandiro ekuita sezvo asingakanganise mashandiro akajairwa muwaya mushure mekupeta kwapera. Naizvozvo, kugonesa masangano imwe dura rekuchengetedza pavanenge vachiona uye nekuzivisa chiitiko chekufungidzira panetiweki yavo uye nekutarisa kune latency matambudziko anogona kuitika panguva dzepamusoro dzekushandisa.
Iyo Network TAP Inoshanda Sei?
Network TAPs michina yakaoma inoita kuti vatungamiri vaone kushanda kwenetwork yavo yese pasina kukanganisa kushanda kwayo. Iwo maturusi ekunze anoshandiswa kutarisa basa revashandisi, kuona traffic yakaipa uye kuchengetedza network kuchengetedzwa nekubvumira kuongororwa kwakadzama kweiyo data inoyerera ichipinda nekubuda mairi. Manetiweki TAPs anovharisa iyo yemuviri layer apo mapaketi anofamba achiyambuka tambo nema switch uye nepamusoro ma layer panogara maapplication.
A Network TAP inoita senge passive port switch inovhura maviri chaiwo madoko kuti atore ese anouya uye anobuda traffic kubva kune chero network yekubatanidza inopfuura nayo. Chigadzirwa chacho chakagadzirirwa kuva 100% chisingaiti, saka kunyange ichigonesa kuongorora kwakazara, kufembedza, uye kusefa kwepaketi yedata, Network TAPs haikanganise kana kukanganisa kushanda kwetiweki yako chero nzira.
Uyezve, vanongoshanda sematanho ekufambisa data rakakodzera kune dzakatarwa dzekutarisa nzvimbo; izvi zvinoreva kuti havakwanise kuongorora kana kuongorora ruzivo rwavanounganidza - zvinoda chimwe chishandiso chechitatu-bato kuti chikwanise kuzviita. Izvi zvinobvumira vatariri kunyatso kudzora uye kuchinjika kana zvasvika pakugadzirisa mashandisiro avanogona kushandisa zvakanyanya maNetwork TAPs ivo vachienderera mberi nemabasa vasingavhiringike pane yese network yavo.
Sei Tichida Network TAP?
Network TAPs inopa hwaro hwekuve neyakajeka uye yakasimba kuoneka uye yekutarisa system pane chero network. Nekupinda mukati meiyo yekutaurirana svikiro, vanogona kuona data pawaya saka inogona kufambiswa kune dzimwe chengetedzo kana yekutarisa masisitimu. Ichi chakakosha chikamu chekuonekwa kwetiweki chinovimbisa kuti data rese riripo pamutsetse haripotsa sezvo traffic inopfuura, zvichireva kuti hapana mapaketi anombodonhedzwa.
Pasina maTAP, network haigone kutariswa uye kutariswa zvizere. Vatariri veIT vanogona kutarisisa nekuvimbika kutyisidzira kana kuwana ruzivo rwakakura mumatiweki avo ayo ekunze-e-bhendi masisitimu angadai akavanza nekupa mukana kune ese ruzivo rwetraffic.
Saka nekudaro, kopi chaiyo yenhaurirano dzinopinda nekubuda dzinopihwa, zvichibvumira masangano kuti aongorore uye aite nekukurumidza pane chero chiitiko chekufungidzira chavangasangana nacho. Kuti masangano emasangano ave akachengeteka uye akavimbika munguva ino yemazuva ano yecybercrime, kushandisa network TAP inofanirwa kunzi inosungirwa.
Mhando dzeNetwork TAPs uye Dzinoshanda Sei?
Kana zvasvika pakuwana nekutarisa network traffic, kune maviri emhando mhando dzeTAPs - Passive TAPs uye Active TAPs. Ose ari maviri anopa nzira iri nyore uye yakachengeteka yekuwana data rwizi kubva kunetiweki pasina kukanganisa kuita kana kuwedzera imwe latency kune system.
A passive TAP inoshanda nekuongorora masaini emagetsi anopfuura neyakajairwa point-to-point cable link pakati pemidziyo miviri, senge pakati pemakomputa nemaseva. Inopa nzvimbo yekubatanidza inobvumira kune yekunze sosi, senge router kana sniffer, kuti iwane kuyerera kwechiratidzo ichiri kupfuura neyayo yekutanga isina kuchinjwa. Rudzi urwu rweTAP runoshandiswa kana uchitarisa kutengeserana kusingatarisire nguva kana ruzivo pakati pemapoinzi maviri.
Iyo inoshanda TAP inoshanda zvakanyanya seyayo inongoita asi ine nhanho yakawedzerwa mukuita - kuunza chiratidzo chekuvandudza chimiro. Nekusimudzira chiratidzo patsva, TAP inoshanda inovimbisa kuti ruzivo runogona kunyatsotariswa isati yaenderera mberi kudzika mutsara.
Izvi zvinopa mhedzisiro inowirirana kunyangwe neakasiyana mazinga emagetsi kubva kune mamwe masosi akabatana neketani. Pamusoro pezvo, iyi mhando yeTAP inomhanyisa kutapurirana chero nzvimbo inodiwa kuitira kuvandudza nguva dzekuita.
Ndeapi Mabhenefiti eNetwork TAP?
Network TAPs dzave kuwedzera mukurumbira mumakore achangopfuura sezvo masangano anoyedza kuwedzera matanho ekuchengetedza uye kuona kuti network yavo inogara ichimhanya zvakanaka. Nekugona kutarisa madoko akawanda panguva imwe chete, Network TAPs inopa inoshanda uye inodhura mhinduro kumasangano ari kutsvaga kuwana zvirinani kuoneka mune zviri kuitika mumatiweki avo.
Pamusoro pezvo, zvine maficha akadai sekudzivirira kwekudzivirira, kuunganidzwa kwepaketi, uye kugona kusefa, Network TAPs inogona kupawo masangano nzira yakachengeteka yekuchengetedza network yavo uye kupindura nekukurumidza kune zvinogona kutyisidzira.
Network TAPs inopa masangano mabhenefiti akati wandei, akadai se:
-Kuwedzera kuoneka mune network traffic inoyerera.
- Kuvandudzwa kwekuchengetedza uye kutevedzera.
-Kudzikisira kunonoka nekupa nzwisiso huru muchikonzero chechero nyaya.
-Kuwedzera kuwanikwa kwetiweki nekubvumira yakazara duplex yekutarisa kugona.
- Yakaderedzwa mutengo wevaridzi sezvo ivo vanowanzo hupfumi kupfuura mamwe mhinduro.
Network TAP vs. SPAN Port Mirror(Nzira yekubata Network Traffic? Network Tap vs Port Mirror?):
Network TAPs (Traffic Access Points) uye SPAN (Switched Port Analyzer) zviteshi zvinhu zviviri zvakakosha zvekutarisa network traffic. Nepo ese ari maviri achipa kuoneka mumatiweki, misiyano isina kujeka pakati pezviviri izvi inofanirwa kunzwisiswa kuti ione kuti ndeipi inonyatsokodzera imwe mamiriro.
A Network TAP chishandiso chekunze chinobatana kusvika padanho rekubatanidza pakati pemidziyo miviri inobvumira kutariswa kwekutaurirana kunopfuura nemairi. Iyo haishandure kana kukanganisa data iri kufambiswa uye haina kutsamira pane switch yakagadzirirwa kuishandisa.
Kune rimwe divi, chiteshi cheSPAN imhando yakakosha yekuchinja chiteshi umo traffic inouya neinobuda inotaridzwa kune imwe chiteshi nekuda kwekutarisa. SPAN ports inogona kunyanya kuoma kugadzirisa kupfuura Network TAPs, uye inodawo kushandiswa kwekushandura kushandiswa.
Naizvozvo, maNetwork TAPs akanyanya kukodzera kumamiriro ezvinhu anoda kuoneka kwakanyanya, nepo SPAN ports ari akanakisa kune akareruka ekutarisa mabasa.
