Wakambonzwa nezve network tap here? Kana uchishanda mumunda we network kana cybersecurity, unogona kunge uchiziva mudziyo uyu. Asi kune avo vasiri, zvinogona kuva chakavanzika.
Munyika yanhasi, kuchengetedzeka kwenetiweki kwakakosha kupfuura kare. Makambani nemasangano vanovimba nenetiweki dzavo kuchengetedza ruzivo rwakakosha uye kutaurirana nevatengi nevatinoshanda navo. Vangaite sei kuti netiweki yavo ive yakachengeteka uye isina mvumo?
Chinyorwa chino chichaongorora kuti chii chinonzi network tap, mashandiro ainoita, uye kuti nei chiri chishandiso chakakosha chekuchengetedza network. Saka ngatidzidzei zvakawanda nezve mudziyo uyu une simba.
Chii chinonzi Network TAP (Terminal Access Point)?
MaNetwork TAP akakosha pakubudirira uye kuchengetedzwa kwenetwork. Anopa nzira dzekutarisa, kuongorora, kuteedzera, uye kuchengetedza zvivakwa zvenetwork. MaNetwork TAP anogadzira "kopi" yetraffic, zvichiita kuti michina yakasiyana-siyana yekutarisa iwane ruzivo irworwo pasina kukanganisa kufamba kwekutanga kwemapaketi edata.
Midziyo iyi yakaiswa zvakanaka munzvimbo dzese dzenetwork kuitira kuti ive nechokwadi chekuti pane kutariswa kwakanyatsonaka.
Masangano anogona kuisa maTAP enetwork panzvimbo dzavanofunga kuti dzinofanira kucherechedzwa, kusanganisira asi kwete chete kunzvimbo dzekuunganidza data, ongororo, kutarisa kwakajairika, kana zvakanyanya kukosha zvakaita sekuona kupinda kwedata.
Chishandiso cheTAP chenetwork hachichinje mamiriro aripo echero paketi iri panetwork inoshanda; chinongogadzira kopi yeketi yega yega inotumirwa kuitira kuti igone kutumirwa kuburikidza neinterface yayo yakabatana nemidziyo yekutarisa kana mapurogiramu.
Maitiro ekukopa anoitwa pasina kuomesa kugona kwekushanda sezvo asingakanganisi mashandiro akajairika muwaya mushure mekugogodza kwapera. Nokudaro, zvinoita kuti masangano ave nerumwe runyararo panguva yekuona nekuzivisa zviitiko zvinofungirwa panetwork yavo uye kuchengetedza kutarisa matambudziko ekunonoka anogona kuitika panguva yekushandiswa kwakanyanya.
Network TAP Inoshanda Sei?
Network TAPs michina yemhando yepamusoro inoita kuti vatungamiriri vakwanise kuongorora mashandiro enetwork yavo yese pasina kukanganisa mashandiro ayo. Idzi ndidzo midziyo yekunze inoshandiswa kutarisa mashandiro emushandisi, kuona traffic yakaipa uye kuchengetedza kuchengetedzwa kwenetwork nekubvumira kuongororwa kwakadzama kwedata rinopinda nekubuda mariri. Network TAPs dzinobatanidza layer chaiyo iyo mapaketi anofamba netambo neswichi uye layer yepamusoro apo maapplication anogara.
Network TAP inoshanda sechinochinjisa chinovhura ma "virtual ports" maviri kuti atore traffic yese inopinda neinobuda kubva kune chero network connections inopfuura nepakati payo. Chishandiso ichi chakagadzirwa kuti chisapindire zvachose, saka kunyangwe chichigonesa kutarisa, kunhuwidza, uye kusefa mapaketi edata, Network TAPs hadzikanganise kana kukanganisa mashandiro enetwork yako nechero nzira.
Uyezve, vanoshanda senzira dzekutumira data rakakodzera kunzvimbo dzakatarwa dzekutarisa; izvi zvinoreva kuti havakwanise kuongorora kana kuongorora ruzivo rwavanounganidza - zvichireva kuti chimwe chishandiso chechitatu chinokwanisa kuita izvozvo. Izvi zvinobvumira vatungamiriri kutonga kwakaringana uye kuchinjika kana zvasvika pakugadzirisa mashandisiro avangaita Network TAPs dzavo uku vachiramba vachishanda pane mamwe ma network avo pasina kukanganiswa.
Sei Tichida Network TAP?
Network TAPs dzinopa hwaro hwekuva nehurongwa hwakasimba uye hwakasimba hwekuonekwa nekutarisa pane chero network. Nekushandisa nzira yekutaurirana, vanogona kuona data riri pawaya kuitira kuti rigone kutumirwa kune dzimwe nzira dzekuchengetedza kana dzekutarisa. Ichi chikamu chakakosha chekuonekwa kwenetiweki chinoita kuti data rese riripo pawaya risapotsa sezvo traffic ichipfuura, zvichireva kuti hapana mapaketi anodonhedzwa.
Pasina TAPs, network haigone kutariswa uye kutarisirwa zvizere. Vatariri veIT vanogona kutarisa njodzi dzakavimbika kana kuwana ruzivo rwakakwana pamusoro penetwork dzavo idzo magadzirirwo ekunze kwebhendi aizovanzwa nekupa mukana wekuwana ruzivo rwese rwetraffic.
Saka, kopi chaiyo yekutaurirana kunopinda nekubuda kunopihwa, zvichibvumira masangano kuferefeta uye kuita chimwe chinhu nekukurumidza pane chero chiitiko chinofungirwa chavanogona kusangana nacho. Kuti network dzemasangano dzive dzakachengeteka uye dzakavimbika munguva ino yeutsotsi hwepaindaneti, kushandisa network TAP kunofanirwa kuonekwa sekumanikidzwa.
Mhando dzeNetwork TAPs uye Mashandiro Adzo?
Kana zvasvika pakuwana nekutarisa traffic yenetwork, kune mhando mbiri huru dzeTAPs - Passive TAPs neActive TAPs. Dzese dzinopa nzira iri nyore uye yakachengeteka yekuwana data stream kubva kune network pasina kukanganisa mashandiro kana kuwedzera latency kune system.
TAP inoshanda nekutarisa masaini emagetsi anopfuura nepakati pechisungo chetambo chinongedzo chepakati pemidziyo miviri, senge pakati pemakombiyuta nemasevha. Inopa nzvimbo yekubatanidza inobvumira nzvimbo yekunze, senge router kana sniffer, kuti isvike pakuyerera kwechiratidzo ichiri kupfuura nepaya yainoenda isina kuchinjwa. Rudzi urwu rweTAP runoshandiswa pakutarisa kutengeserana kunoenderana nenguva kana ruzivo pakati penzvimbo mbiri.
TAP inoshanda inoshanda zvakafanana neyayo isingashande asi ine imwe nhanho - ichiunza chinhu chekugadzirisa masaini. Nekushandisa kuvandudzwa kwemasaini, TAP inoshanda inoita kuti ruzivo rukwanise kutariswa nemazvo rusati rwaenderera mberi.
Izvi zvinopa mhedzisiro yakafanana kunyangwe paine mazinga akasiyana emagetsi kubva kune dzimwe nzvimbo dzakabatana pamwe chete necheni. Pamusoro pezvo, rudzi urwu rweTAP runokurumidza kutumira ma transmissions panzvimbo chero ipi zvayo inodiwa kuitira kuvandudza nguva yekushanda.
Ndezvipi zvakanakira Network TAP?
Network TAPs yave kufarirwa zvakanyanya mumakore achangopfuura sezvo masangano anoedza kuwedzera matanho avo ekuchengetedza uye kuona kuti network dzavo dzinogara dzichishanda zvakanaka. Nekukwanisa kutarisa maports akawanda panguva imwe chete, Network TAPs inopa mhinduro inoshanda uye isingadhuri kumasangano ari kutsvaga kuona zviri kuitika mumanetwork avo zviri nani.
Pamusoro pezvo, nemabasa akadai sekudzivirira kuburikidza nepaseti, kuunganidzwa kwemapaketi, uye kugona kusefa, Network TAPs inogonawo kupa masangano nzira yakachengeteka yekuchengetedza network dzavo uye kupindura nekukurumidza kune njodzi dzinogona kuitika.
Network TAPs inopa masangano mabhenefiti akati wandei, akadai se:
- Kuwedzera kuonekwa kwemafambiro e network traffic.
- Kuchengetedzwa kwakavandudzwa uye kutevedzera mitemo.
- Kuderedza nguva yekuzorora nekupa ruzivo rwakakura pamusoro pechikonzero chezvinetso chero zvipi zvazvo.
- Kuwedzera kuwanikwa kwenetiweki nekubvumira kugona kwakazara kwekutarisa duplex.
- Kuderedzwa kwemutengo wekuva muridzi wezvinhu sezvo kazhinji zvichidhura kupfuura dzimwe mhinduro.
Network TAP vs. SPAN Port Mirror (Ungatora sei vanhu vari paNetwork Tap vs Port Mirror?):
MaNetwork TAPs (Traffic Access Points) uye SPAN (Switched Port Analyzer) maturusi maviri akakosha ekutarisa traffic yenetwork. Kunyange zvazvo ese ari maviri achipa mukana wekuona network, musiyano uri pakati pezviviri izvi unofanirwa kunzwisiswa kuti uone kuti ndeipi yakakodzera mamiriro ezvinhu akati.
Network TAP mudziyo wekunze unobatanidza panzvimbo yekubatana pakati pemidziyo miviri inobvumira kutarisa kutaurirana kunopfuura nepakati payo. Haichinje kana kukanganisa data riri kutumirwa uye haitsamiri pane switch yakagadzirirwa kuishandisa.
Kune rumwe rutivi, SPAN port imhando yakakosha yeswitch port umo traffic inopinda neinobuda inotariswa kune imwe port kuti ionekwe. SPAN ports dzinogona kuoma kugadzirisa kupfuura Network TAPs, uye dzinodawo kushandiswa kweswitch.
Saka, Network TAPs dzakakodzera mamiriro ezvinhu anoda kuonekwa zvakanyanya, nepo maSPAN ports ari akanakira mabasa ari nyore ekutarisa.
