Ua lohe mua paha ʻoe i kahi paʻi pūnaewele? Inā ʻoe e hana ma ka ʻoihana pūnaewele a i ʻole cybersecurity, ʻike paha ʻoe i kēia hāmeʻa. Akā no ka poʻe ʻaʻole, hiki ke lilo i mea pohihihi.
I kēia ao, ʻoi aku ka nui o ka palekana o ka pūnaewele ma mua o ka wā ma mua. Ke hilinaʻi nei nā ʻoihana a me nā hui i kā lākou pūnaewele e mālama i ka ʻikepili koʻikoʻi a kamaʻilio pū me nā mea kūʻai aku a me nā hoa. Pehea e hiki ai iā lākou ke hōʻoia i ka palekana a me ka ʻole o kā lākou pūnaewele mai ka ʻae ʻole ʻia?
E ʻimi ana kēia ʻatikala i ke ʻano o ka paʻi pūnaewele, pehea e hana ai, a no ke kumu he mea pono ia no ka palekana pūnaewele. No laila e luʻu kākou a aʻo hou aʻe e pili ana i kēia hāmeʻa ikaika.
He aha ka TAP Pūnaewele (Terminal Access Point)?
Pono nā TAP pūnaewele no ka holomua a me ka palekana o ka hana pūnaewele. Hāʻawi lākou i nā ala e nānā, nānā, nānā, a hoʻopaʻa i nā ʻōnaehana pūnaewele. Hoʻokumu nā TAP pūnaewele i "kope" o ke kaʻa, e hiki ai i nā mea nānā like ʻole ke komo i kēlā ʻike me ka ʻole o ka hoʻopili ʻana i ke kahe kumu o nā ʻeke ʻikepili.
Hoʻonohonoho pono ʻia kēia mau mea hana i loko o ka ʻoihana pūnaewele e hōʻoia i ka nānā pono loa.
Hiki i nā hui ke hoʻokomo i nā TAP pūnaewele ma nā wahi a lākou e manaʻo ai he pono ke nānā ʻia, e komo pū ana akā ʻaʻole i kaupalena ʻia i nā wahi no ka hōʻiliʻili ʻana i ka ʻikepili, ka nānā ʻana, ka nānā ākea, a i ʻole nā mea koʻikoʻi e like me ka ʻike intrusion.
ʻAʻole hoʻololi ka hāmeʻa TAP pūnaewele i ke kūlana o kēia ʻeke ma ka pūnaewele hoʻoikaika; hana wale ia i kope o kēlā me kēia ʻeke i hoʻouna ʻia i hiki ke hoʻokuʻu ʻia ma o kāna interface pili i nā polokalamu nānā a i ʻole nā papahana.
Hoʻokō ʻia ke kaʻina hana kope me ke koʻikoʻi ʻole i ka hiki ke hana no ka mea ʻaʻole ia e keakea i nā hana maʻamau i ka uea ma hope o ka paʻa ʻana. No laila, hiki i nā hui ke hoʻonui i ka palekana i ka ʻike ʻana a me ka makaʻala ʻana i nā hana kānalua ma kā lākou pūnaewele a me ka nānā ʻana i nā pilikia latency e hiki mai ana i ka wā hoʻohana kiʻekiʻe.
Pehea e hana ai kahi TAP Pūnaewele?
ʻO nā TAP pūnaewele he mau mea hana maʻalahi e hiki ai i nā luna hoʻomalu ke nānā i ka hana o kā lākou pūnaewele holoʻokoʻa me ka hoʻopau ʻole i kāna hana. He mau mea waho ia i hoʻohana ʻia no ka nānā ʻana i ka hana o ka mea hoʻohana, ʻike i nā kaʻa hewa a pale i ka palekana pūnaewele ma o ka ʻae ʻana i ka loiloi hohonu o ka ʻikepili e kahe ana i loko a i waho. Hoʻopili nā TAP pūnaewele i ka papa kino kahi e hele ai nā ʻeke ma nā kelepona a me nā hoʻololi a me nā papa luna kahi e noho ai nā noi.
Hoʻohana ʻia kahi TAP Pūnaewele ma ke ʻano he hoʻololi port passive e wehe ana i ʻelua mau awa virtual e hopu i nā kaʻa komo a me waho mai nā pilina pūnaewele e hele ana ma ia. Hoʻolālā ʻia ka hāmeʻa i 100% non-intrusive, no laila ʻoiai ʻo ia e hiki ai i ka nānā piha ʻana, ka honi ʻana, a me ke kānana ʻana i nā ʻeke ʻikepili, ʻaʻole e hoʻopilikia a hoʻopilikia paha nā TAP Pūnaewele i ka hana o kāu pūnaewele ma kekahi ʻano.
Eia kekahi, hana wale lākou ma ke ʻano he ala no ka hoʻokahe ʻana i ka ʻikepili kūpono i nā wahi nānā i koho ʻia; ʻo ia hoʻi, ʻaʻole hiki iā lākou ke kālailai a loiloi paha i ka ʻike a lākou e hōʻiliʻili ai - e koi ana i kahi mea hana ʻē aʻe e hiki ai ke hana pēlā. Hāʻawi kēia i nā luna hoʻomalu i ka mana pololei a me ka maʻalahi i ka wā e pili ana i ka hoʻopili ʻana pehea e hiki ai iā lākou ke hoʻohana maikaʻi i kā lākou TAP Pūnaewele ʻoiai e hoʻomau mau ana i nā hana me ka pau ʻole o kā lākou pūnaewele.
No ke aha mākou e makemake ai i kahi TAP Pūnaewele?
Hāʻawi nā TAP pūnaewele i ke kumu no ka loaʻa ʻana o ka ʻike a me ka ʻōnaehana mākaʻikaʻi ma kēlā me kēia pūnaewele. Ma ka paʻi ʻana i ka media kamaʻilio, hiki iā lākou ke ʻike i ka ʻikepili ma ka uea i hiki ke hoʻoheheʻe ʻia i nā ʻōnaehana palekana a nānā paha. ʻO kēia ʻāpana koʻikoʻi o ka ʻike pūnaewele e hōʻoia i ka ʻike ʻole ʻia o nā ʻikepili a pau ma ka laina i ka wā e hele ai ke kaʻa, ʻo ia hoʻi ʻaʻole hāʻule nā paʻi.
Me ka ʻole o nā TAP, ʻaʻole hiki ke nānā pono a mālama ʻia kahi pūnaewele. Hiki i nā luna hoʻoponopono IT ke nānā pono i nā mea hoʻoweliweli a i ʻole e loaʻa i ka ʻike kikoʻī i kā lākou pūnaewele e hūnā ʻia nā hoʻonohonoho waho-o-band ma o ka hāʻawi ʻana i ka ʻike i nā ʻike āpau.
No laila, hāʻawi ʻia kahi kope pololei o nā kamaʻilio komo a puka ʻana, e ʻae ana i nā hui e noiʻi a hana wikiwiki i nā hana kānalua a lākou e hālāwai ai. No ka palekana a me ka hilinaʻi o nā ʻoihana pūnaewele i kēia au hou o ka cybercrime, pono e manaʻo ʻia ka hoʻohana ʻana i kahi pūnaewele TAP he mea pono.
Nā ʻano o nā TAP pūnaewele a pehea lākou e hana ai?
I ka hiki ʻana a me ka nānā ʻana i ka ʻoihana pūnaewele, aia ʻelua mau ʻano kumu nui o TAPs - TAP Passive a me Active TAPs. Hāʻawi nā mea ʻelua i kahi ala maʻalahi a paʻa hoʻi e komo i kahi kahawai ʻikepili mai kahi pūnaewele me ka ʻole e hoʻopau i ka hana a i ʻole ka hoʻohui ʻana i ka latency hou i ka ʻōnaehana.
Hana ʻia kahi TAP passive ma ka nānā ʻana i nā hōʻailona uila e hele ana ma kahi loulou uwea maʻamau ma waena o nā mea ʻelua, e like me waena o nā kamepiula a me nā kikowaena. Hāʻawi ia i kahi wahi pili e ʻae ana i kahi kumu waho, e like me ke alalai a i ʻole sniffer, e komo i ke kahe o ka hōʻailona ʻoiai e hele mau ana i kāna huakaʻi mua me ka loli ʻole. Hoʻohana ʻia kēia ʻano TAP i ka wā e nānā ai i nā kālepa pili manawa a i ʻole ka ʻike ma waena o ʻelua mau wahi.
Hana ʻia kahi TAP ikaika e like me kona hoa passive akā loaʻa kahi pae hou i ke kaʻina hana - hoʻokomo i kahi hiʻohiʻona hōʻailona hōʻailona. Ma ka hoʻohana ʻana i ka hana hou ʻana o ka hōʻailona, hiki i ka TAP ikaika ke nānā pono i ka ʻike ma mua o ka hele ʻana i lalo o ka laina.
Hāʻawi kēia i nā hopena like ʻole me nā pae volta like ʻole mai nā kumu ʻē aʻe i pili pū me ke kaulahao. Hoʻohui hou, ʻo kēia ʻano TAP e hoʻolalelale i nā hoʻouna ʻana ma nā wahi i koi ʻia i mea e hoʻomaikaʻi ai i nā manawa hana.
He aha nā pōmaikaʻi o kahi TAP Pūnaewele?
Ua lilo nā TAP pūnaewele i mea kaulana i nā makahiki i hala iho nei no ka hoʻoikaika ʻana o nā hui e hoʻonui i kā lākou mau hana palekana a hōʻoia i ka holo pono ʻana o kā lākou pūnaewele. Me ka hiki ke nānā i nā awa he nui i ka manawa like, hāʻawi ʻo Network TAPs i kahi hopena kūpono a maikaʻi hoʻi no nā hui e ʻimi nei e ʻike maikaʻi i nā mea e hana nei ma kā lākou pūnaewele.
Eia hou, me nā hiʻohiʻona e like me ka pale bypass, ka hōʻuluʻulu packet, a me ka hiki ke kānana, hiki i nā TAP Pūnaewele ke hāʻawi i nā hui i kahi ala palekana e mālama i kā lākou pūnaewele a pane koke i nā mea hoʻoweliweli.
Hāʻawi nā TAP pūnaewele i nā hui me nā pono he nui, e like me:
- Hoʻonui i ka ʻike i nā kahe kaʻa pūnaewele.
- Hoʻonui i ka palekana a me ka hoʻokō.
- Hoʻemi ʻia ka manawa hoʻomaha ma o ka hāʻawi ʻana i ka ʻike nui i ke kumu o kekahi pilikia.
- Hoʻonui ʻia ka loaʻa ʻana o ka pūnaewele ma ka ʻae ʻana i nā mana nānā duplex piha.
- Hoʻemi ʻia ke kumu kūʻai o ka ʻona no ka mea ʻoi aku ka ʻoi aku o ka waiwai ma mua o nā hoʻonā ʻē aʻe.
Pūnaewele TAP vs. SPAN Port Mirror(Pehea e kiʻi ai i ke kaʻa kaʻa pūnaewele? Pūʻulu Pūnaewele vs Port Mirror?):
ʻO nā TAP Pūnaewele (Nā Kūlana Kūleʻa) a me nā awa SPAN (Switched Port Analyzer) ʻelua mau mea pono no ka nānā ʻana i ka hele ʻana o ka pūnaewele. ʻOiai hāʻawi nā mea ʻelua i ka ʻike i loko o nā pūnaewele, pono e hoʻomaopopo ʻia nā ʻokoʻa liʻiliʻi ma waena o nā mea ʻelua e hoʻoholo ai i ka mea kūpono loa no kahi kūlana.
ʻO kahi TAP Pūnaewele kahi mea waho e hoʻopili ai i kahi o ka pilina ma waena o nā mea ʻelua e hiki ai ke nānā i nā kamaʻilio e hele ana ma ia. ʻAʻole ia e hoʻololi a keʻakeʻa paha i ka ʻikepili i hoʻouna ʻia a ʻaʻole hilinaʻi i ka hoʻololi i hoʻonohonoho ʻia e hoʻohana.
Ma ka ʻaoʻao ʻē aʻe, ʻo kahi awa SPAN kahi ʻano kūikawā o ke awa hoʻololi kahi e hoʻohālikelike ʻia ai nā kaʻa komo a puka i waho i kahi awa ʻē aʻe no ka nānā ʻana. ʻOi aku ka paʻakikī o ka hoʻonohonoho ʻana i nā awa SPAN ma mua o nā TAP Pūnaewele, a koi pū kekahi i ka hoʻohana ʻana i kahi hoʻololi e hoʻohana ʻia.
No laila, ʻoi aku ka maikaʻi o nā TAP Pūnaewele no nā kūlana e koi ana i ka ʻike kiʻekiʻe, ʻoiai ʻoi aku ka maikaʻi o nā awa SPAN no nā hana nānā maʻalahi.
