Kua rongo kē koe i te kupu "network tap"? Mena kei te mahi koe i te ao whatunga, i te ao haumarutanga tukutuku rānei, tera pea e mōhio ana koe ki tēnei taputapu. Engari ki te hunga kāore i te mōhio, he mea ngaro pea.
I tēnei ao o nāianei, he mea nui ake te haumarutanga whatunga i ngā wā katoa o mua. Ka whakawhirinaki ngā kamupene me ngā whakahaere ki ā rātou whatunga hei penapena raraunga tairongo, hei whakawhitiwhiti kōrero hoki ki ngā kiritaki me ngā hoa mahi. Me pēhea e taea ai e rātou te whakarite kia haumaru tā rātou whatunga, kia kore ai hoki e uru mai he mana kore?
Ka tūhuratia e tēnei tuhinga te tikanga o te whatunga tap, me pēhea tana mahi, me te take he taputapu nui mō te haumarutanga whatunga. Nō reira, kia ruku tātou ki roto, kia ako atu ai mō tēnei taputapu kaha.
He aha te TAP Whatunga (Pūwāhi Uru Whakamutunga)?
He mea nui ngā TAP Whatunga mō te angitu me te haumaru o te mahi whatunga. Mā ēnei ka taea te aroturuki, te tātari, te whai, me te tiaki i ngā hanganga whatunga. Ka hangaia e ngā TAP Whatunga he "tārua" o te waka, ka taea ai e ngā taputapu aroturuki te uru atu ki aua mōhiohio me te kore e whakararuraru i te rere taketake o ngā mōkihi raraunga.
Kua whakanohoia ēnei taputapu ki ngā wāhi rautaki puta noa i te hanganga whatunga kia pai ai te aroturukitanga.
Ka taea e ngā whakahaere te tāuta i ngā TAP whatunga ki ngā wāhi e whakaaro ana rātou me mātaki, tae atu ki ngā wāhi kohikohi raraunga, tātari, aroturuki whānui, me ētahi atu mea nui pēnei i te kimi urutomo.
Kāore te pūrere TAP whatunga e whakarerekē i te āhua o tētahi mōkihi kei runga i te whatunga hohe; ka hangaia he tārua o ia mōkihi kua tukuna kia taea ai te tuku atu mā tōna atanga e hono ana ki ngā pūrere aroturuki, ki ngā kaupapa rānei.
Ka whakahaerehia te tukanga tārua me te kore e whakararu i te kaha mahi, nā te mea kāore e whakararuraru i ngā mahi noa i roto i te waea i muri i te otinga o te pato. Nō reira, ka taea e ngā whakahaere te whakarato i tētahi paparanga haumarutanga anō i a rātou e kite ana me te whakatūpato ana i ngā mahi whakapae i runga i tā rātou whatunga, me te tirotiro hoki i ngā raruraru whakaroa ka puta i ngā wā tino nui o te whakamahinga.
He pēhea te mahi a te TAP Whatunga?
He taputapu matatau ngā Network TAP e āhei ai ngā kaiwhakahaere ki te aromatawai i te mahi a tā rātou whatunga katoa me te kore e whakararuraru i tana mahi. He taputapu o waho ēnei e whakamahia ana hei aroturuki i ngā mahi a ngā kaiwhakamahi, hei kimi i ngā waka kino, hei tiaki hoki i te haumarutanga o te whatunga mā te tuku i te tātaritanga hohonu ake o ngā raraunga e rere ana ki roto, ki waho hoki. Ka hono ngā Network TAP i te paparanga tinana e haere ai ngā mōkihi puta noa i ngā taura me ngā pana me ngā paparanga o runga kei reira ngā tono.
He rite te mahi a te Network TAP ki tētahi pana tauranga kore e mahi ana, e whakatuwhera ana i ngā tauranga mariko e rua hei hopu i ngā waka katoa e haere mai ana, e haere atu ana hoki i ngā hononga whatunga katoa e tika ana mā roto. Kua hangaia te taputapu kia kore e pokanoa, nō reira, ahakoa e āhei ana ki te aroturuki whānui, te hongi, me te tātari i ngā mōkihi raraunga, kāore ngā Network TAP e whakararuraru, e whakararuraru rānei i te mahi a tō whatunga i tētahi ara.
Hei tāpiritanga, he hongere anake tā rātou e mahi ai hei whakawhiti raraunga e tika ana ki ngā wāhi aroturuki kua tohua; ko te tikanga tēnei kāore e taea e rātou te tātari, te arotake rānei i ngā mōhiohio e kohia ana e rātou – me whakamahi i tētahi atu taputapu tuatoru hei mahi i tēnā. Mā tēnei ka taea e ngā kaiwhakahaere te whakahaere tika me te ngāwari ina tae mai ki te whakarite me pēhea te whakamahi pai i ā rātou TAP Whatunga me te haere tonu o ngā mahi i runga i te toenga o tā rātou whatunga.
He aha tātou e hiahia ai ki tētahi TAP Whatunga?
Mā ngā TAP whatunga ka whakaratohia te tūāpapa mō te whai pūnaha tirohanga whānui, pakari hoki mō tētahi whatunga. Mā te whakamahi i te reo whakawhitiwhiti kōrero, ka taea e rātou te tautuhi i ngā raraunga kei runga i te waea kia taea ai te tuku atu ki ētahi atu pūnaha haumarutanga, aroturuki rānei. Mā tēnei wāhanga nui o te tirohanga whatunga ka whakarite kia kore e ngaro ngā raraunga katoa kei runga i te raina i te wā e haere ana te waka, arā, kāore he mōkihi e taka.
Ki te kore he TAP, kāore e taea te aro turuki me te whakahaere i tētahi whatunga. Ka taea e ngā kaiwhakahaere IT te aro turuki pono mō ngā tūmomo riri, te whiwhi māramatanga taipitopito rānei mō ā rātou whatunga e hunaia ana e ngā whirihoranga i waho o te roopu mā te whakarato urunga ki ngā mōhiohio katoa e pā ana ki te rere o ngā raraunga.
Nō reira, ka whakaratohia he tārua tika o ngā whakawhitiwhitinga taumai me ngā whakawhitiwhitinga atu, kia taea ai e ngā whakahaere te tirotiro me te mahi tere i ngā mahi whakapae ka tūtaki pea rātou. Kia noho haumaru, kia pono hoki ngā whatunga o ngā whakahaere i tēnei ao hou o te hara ipurangi, me kī he mea whakahau te whakamahi i te whatunga TAP.
Ngā Momo TAP Whatunga me tā Rātou Mahi?
Mō te uru atu me te aroturuki i ngā waka whatunga, e rua ngā momo matua o ngā TAP – ko ngā TAP Passive me ngā TAP Active. He huarahi watea, he huarahi haumaru hoki ēnei e rua ki te uru atu ki te awa raraunga mai i te whatunga, me te kore e whakararuraru i te mahi, e tāpiri atu rānei i te whakaroa ki te pūnaha.
<Ngā TAP Whatunga Whakakorekore>
Ka mahi te TAP kore mahi mā te tirotiro i ngā tohu hiko e haere ana i roto i tētahi hononga taura noa i waenganui i ngā taputapu e rua, pērā i waenganui i ngā rorohiko me ngā tūmau. Ka whakaratohia he pūwāhi hononga e āhei ai tētahi pūtake o waho, pērā i te pouara, i te kaiwhakamārama rānei, ki te uru atu ki te rere o te tohu i a ia e haere tonu ana i roto i tōna ūnga taketake me te kore e whakarerekētia. Ka whakamahia tēnei momo TAP ina aroturukihia ngā whakawhitiwhitinga wā-tairongo, ngā mōhiohio rānei i waenganui i ngā pūwāhi e rua.
He rite tonu te mahi a te TAP hohe ki tōna hoa mahi kore mahi, engari he taahiraa anō kei roto i te tukanga – arā, ko te whakaurunga o tētahi āhuatanga whakahou tohu. Mā te whakamahi i te whakahou tohu, ka whakarite te TAP hohe kia taea te aro turuki tika i ngā mōhiohio i mua i te haere tonu ki raro.
Ka puta he hua ōrite ahakoa ngā taumata ngaohiko rerekē mai i ētahi atu pūtake e hono ana i te mekameka. Hei tāpiri, ka tere ake te tuku i ngā tuku i tētahi wāhi e hiahiatia ana hei whakapai ake i ngā wā mahi.
He aha ngā painga o te TAP Whatunga?
Kua piki haere te rongonui o ngā Network TAP i ngā tau tata nei, i te mea e whai ana ngā whakahaere ki te whakapiki ake i ā rātou tikanga haumarutanga, me te whakarite kia pai tonu te rere o ā rātou whatunga. Mā te kaha ki te aroturuki i ngā tauranga maha i te wā kotahi, ka whakaratohia e ngā Network TAP he otinga whai hua, whai hua hoki mō ngā whakahaere e hiahia ana kia pai ake te tirohanga ki ngā mea e tupu ana puta noa i ā rātou whatunga.
Hei tāpiritanga, me ngā āhuatanga pēnei i te tiaki taha, te whakahiato mōkihi, me ngā āheinga tātari, ka taea hoki e ngā Network TAP te whakarato i tētahi huarahi haumaru ki ngā whakahaere hei pupuri i ā rātou whatunga me te urupare wawe ki ngā tūmomo riri pea.
He maha ngā painga ka tukuna e ngā TAP whatunga ki ngā whakahaere, pēnei i:
- Te kitea nuitia o ngā rerenga o ngā waka whatunga.
- Te whakapai ake i te haumarutanga me te tutuki i ngā whakaritenga.
- Ka whakaitihia te wā kore mahi mā te whakarato i te māramatanga whānui ake ki te pūtake o ngā raruraru.
- Te whakanui ake i te wātea o te whatunga mā te tuku i ngā āheinga aroturuki takirua katoa.
- He iti ake te utu o te mana pupuri nā te mea he iti ake te ōhanga i ērā atu otinga.
Whatunga TAP vs. Whakaata Tauranga SPANMe pēhea te hopu i te haere o te whatunga? Network Tap vs Port Mirror?):
Ko ngā tauranga Network TAP (Traffic Access Points) me SPAN (Switched Port Analyzer) he taputapu nui e rua mō te aroturuki i te haere o te whatunga. Ahakoa e whakarato ana ēnei i te tirohanga ki ngā whatunga, me mārama ngā rerekētanga ngawari i waenganui i ngā mea e rua kia mōhio ai ko tēhea te mea tino pai mō tētahi āhuatanga motuhake.
He taputapu o waho te Network TAP e hono ana ki te pūwāhi hononga i waenga i ngā taputapu e rua, e āhei ai te aroturuki i ngā whakawhitiwhitinga kōrero e haere ana mā roto. Kāore e whakarerekē, e whakararuraru rānei i ngā raraunga e tukuna ana, ā, kāore e whakawhirinaki ana ki te pana kua whirihorahia hei whakamahi.
I tētahi atu taha, he momo tauranga pana motuhake te tauranga SPAN e whakaatahia ana ngā waka e haere mai ana, e haere atu ana ki tētahi atu tauranga hei aroturuki. He uaua ake te whirihora i ngā tauranga SPAN i ngā TAP Whatunga, ā, me whakamahi hoki i tētahi pana hei whakamahi.
Nō reira, he pai ake ngā Network TAP mō ngā āhuatanga e hiahia ana kia kitea nuitia, ko ngā tauranga SPAN ia he pai ake mō ngā mahi aroturuki māmā ake.
