Yini ekwenzela yona i-Network Packet Broker (NPB)?

Uyini uMthengisi Wephakethe Lenethiwekhi?

I-Network Packet Broker ebizwa ngokuthi “i-NPB” iyithuluzi elithwebula, likopishe futhi lihlanganise i-Network Data Traffic engaphakathi noma engaphandle kwebhendi ngaphandle kokulahlekelwa yi-Packet njengo-“Packet Broker”, eliphatha futhi lilethe i-Right Packet kumathuluzi afanele njenge-IDS, i-AMP, i-NPM, i-Monitoring and Analysis System njenge-“Packet Carrier”.

Yini engenziwa yi-Network Packet Broker (NPB)?

Ngokwethiyori, ukuhlanganisa, ukuhlunga, nokuletha idatha kuzwakala kulula. Kodwa empeleni, i-NPB ehlakaniphile ingenza imisebenzi eyinkimbinkimbi kakhulu ekhiqiza ukusebenza kahle okukhulu kanye nezinzuzo zokuphepha.

Ukulinganisela umthwalo kungenye yemisebenzi. Isibonelo, uma uthuthukisa inethiwekhi yakho yesikhungo sedatha kusuka ku-1Gbps kuya ku-10Gbps, 40Gbps, noma ngaphezulu, i-NPB ingahlehlisa ijubane ukuze isabalalise ithrafikhi yesivinini esiphezulu kusethi ekhona yamathuluzi okuhlaziya nokuqapha isivinini esiphansi se-1G noma i-2G. Lokhu akugcini nje ngokwandisa inani lokutshalwa kwezimali kwakho kwamanje kokuqapha, kodwa futhi kugwema ukuthuthukiswa okubizayo lapho i-IT ishintsha.

Ezinye izici ezinamandla ezenziwa yi-NPB zifaka:

-Ukukhishwa kwephakethe okungafuneki
Amathuluzi okuhlaziya kanye nokuphepha asekela ukwamukela inani elikhulu lamaphakethe aphindwe kabili athunyelwa kusuka kubasabalalisi abaningi. I-NPB iqeda ukuphindaphindwa ukuze ivimbele ithuluzi ekuchitheni amandla okucubungula lapho kucutshungulwa idatha engadingeki.

-Ukususwa kwe-SSL
Ukubethela kwe-Secure sockets layer (SSL) kuyindlela ejwayelekile yokuthumela ulwazi oluyimfihlo ngokuphephile. Kodwa-ke, abaduni bangafihla nezinsongo zenethiwekhi ezinonya kumaphakethe abethelwe.
Ukuhlola le datha kumele kususwe ukubethela, kodwa ukuqhekeza ikhodi kudinga amandla abalulekile okucubungula. Ama-ejenti ephakethe lenethiwekhi ahamba phambili angalayisha ukubethela kusuka kumathuluzi okuphepha ukuqinisekisa ukubonakala okuphelele ngenkathi enciphisa umthwalo ezinsizeni ezibiza kakhulu.

-Ukufihla Idatha
Ukususwa kokubethela kwe-SSL kuvumela noma ubani onokufinyelela kumathuluzi okuphepha nokuqapha ukuthi abone idatha. I-NPB ingavimba izinombolo zekhadi lesikweletu noma zokuphepha komphakathi, ulwazi lwezempilo oluvikelwe (i-PHI), noma olunye ulwazi oluyimfihlo oluhlonza umuntu (i-PII) ngaphambi kokudlulisa ulwazi, ukuze lungadalulwa kuthuluzi noma kubaphathi balo.

-Ukususa ikhanda
I-NPB ingasusa ama-header afana nama-vlans, ama-vxlans, nama-l3vpns, ngakho-ke amathuluzi angakwazi ukuphatha lawa maphrothokholi asengamukela futhi acubungule idatha yephakethe. Ukubonakala okuqaphela umongo kusiza ekuboneni izinhlelo zokusebenza ezinonya ezisebenza kunethiwekhi kanye nezinyathelo ezishiywe abahlaseli njengoba besebenza ezinhlelweni nasemanethiwekhi.

-Ukuhlakanipha kokusetshenziswa kanye nokusongela
Ukutholwa kusenesikhathi kobuthakathaka kunganciphisa ukulahleka kolwazi olubucayi kanye nezindleko zobuthakathaka ekugcineni. Ukubonakala okuqaphela umongo okunikezwa yi-NPB kungasetshenziswa ukudalula izilinganiso zokungena (i-IOC), ukuhlonza indawo yezindawo zama-vector okuhlasela, kanye nokulwa nezinsongo ze-cryptographic.

Ubuhlakani bohlelo lokusebenza budlulela ngale kwesendlalelo sesi-2 kuya kwesendlalelo sesi-4 (imodeli ye-OSI) sedatha yephakethe kuya kwesendlalelo sesi-7 (isendlalelo sohlelo lokusebenza). Idatha ecebile mayelana nabasebenzisi kanye nokuziphatha kohlelo lokusebenza kanye nendawo kungadalwa futhi kuthunyelwe ukuze kuvinjelwe ukuhlaselwa kwezinga lohlelo lokusebenza lapho ikhodi enonya izenza idatha evamile kanye nezicelo zamakhasimende ezivumelekile.
Ukubonakala okuqaphela umongo kusiza ukubona izinhlelo zokusebenza ezinonya ezisebenza kunethiwekhi yakho kanye nezinyathelo ezishiywe abahlaseli njengoba besebenza ezinhlelweni nakumanethiwekhi.

-Ukusetshenziswa kokuqapha inethiwekhi
Ukubonakala okuqaphela izinhlelo zokusebenza nakho kunomthelela omkhulu ekusebenzeni nasekuphathweni. Ungase ufune ukwazi ukuthi isisebenzi SISEBENZISA nini isevisi esekelwe efwini njengeDropbox noma i-imeyili esekelwe kuwebhu ukuze sidlule izinqubomgomo zokuphepha futhi sidlulise amafayela enkampani, noma lapho isisebenzi sangaphambilini sizama ukufinyelela amafayela sisebenzisa isevisi yokugcina yomuntu siqu esekelwe efwini.
