Yintoni ekwenzela yona iNetwork Packet Broker (NPB)?

Yintoni iNetwork Packet Broker?

I-Network Packet Broker ebizwa ngokuba yi-“NPB” sisixhobo esibamba, siphinda-phinda kwaye sihlanganise i-inline okanye ngaphandle kwe-band Network Data Traffic ngaphandle kokulahleka kwePacket njenge-“Packet Broker”, silawula kwaye sihambise iPacket eyiyo kwiZixhobo eziLungileyo ezifana ne-IDS, i-AMP, i-NPM, iNkqubo yokubeka esweni kunye noHlahlelo njenge-“Packet Carrier”.

Yintoni enokwenziwa yiNetwork Packet Broker (NPB)?

Ngokwethiyori, ukuhlanganisa, ukucoca, kunye nokuhambisa idatha kuvakala kulula. Kodwa eneneni, i-NPB ekrelekrele inokwenza imisebenzi enzima kakhulu evelisa ukusebenza kakuhle kunye neenzuzo zokhuseleko ezikhulayo ngokukhawuleza.

Ukulinganisela umthwalo yenye yemisebenzi. Umzekelo, ukuba uphucula inethiwekhi yakho yeziko ledatha ukusuka kwi-1Gbps ukuya kwi-10Gbps, i-40Gbps, okanye ngaphezulu, i-NPB ingacothisa isantya sokusasaza ithrafikhi yesantya esiphezulu kwiseti ekhoyo yezixhobo zohlalutyo kunye nokubeka iliso zesantya esiphantsi se-1G okanye i-2G. Oku akupheleli nje ekwandiseni ixabiso lotyalo-mali lwakho lwangoku lokubeka iliso, kodwa kukwathintela ukuphuculwa okubizayo xa i-IT ifuduka.

Ezinye izinto ezinamandla ezenziwa yi-NPB ziquka:

-Ukususwa kwepakethi engafunekiyo
Izixhobo zohlalutyo nezokhuseleko zixhasa ukufumana inani elikhulu leepakethi eziphindwe kabini ezithunyelwa ngabasasazi abaninzi. I-NPB iyayisusa into yokuphindaphinda ukuze ithintele isixhobo ekuchitheni amandla okucubungula xa kusetyenzwa idatha engafunekiyo.

-Ukususwa kwe-SSL
Ukubethela i-Secure sockets layer (SSL) yindlela eqhelekileyo yokuthumela ulwazi oluyimfihlo ngokukhuselekileyo. Nangona kunjalo, abaphangi banokufihla izisongelo zenethiwekhi ezinobungozi kwiipakethi ezifihliweyo.
Ukujonga le datha kufuneka kususwe ikhowudi, kodwa ukuqhekeza ikhowudi kufuna amandla abalulekileyo okucubungula. Iiarhente eziphambili zepakethi zenethiwekhi zinokukhupha ikhowudi kwizixhobo zokhuseleko ukuqinisekisa ukubonakala ngokubanzi ngelixa zinciphisa umthwalo kwizixhobo ezibiza kakhulu.

-Ukufihla idatha
Ukususwa kwe-SSL kuvumela nabani na onokufikelela kwizixhobo zokhuseleko kunye nokubeka esweni ukuba abone idatha. I-NPB inokuthintela iiNombolo zekhadi letyala okanye zokhuseleko loluntu, ulwazi lwezempilo olukhuselweyo (i-PHI), okanye olunye ulwazi oluyimfihlo oluchonga umntu (i-PII) ngaphambi kokuba ludlulise ulwazi, ukuze lungatyhilelwanga kwisixhobo okanye kubalawuli baso.

-Ukususa intloko
I-NPB inokususa ii-headers ezifana ne-vlans, i-vxlans, kunye ne-l3vpns, ngoko ke izixhobo ezingakwaziyo ukuphatha ezi protocols zisenokufumana kwaye ziqhube idatha yepakethi. Ukubonakala okuqaphela imeko kunceda ekuchongeni usetyenziso olunobungozi olusebenza kwinethiwekhi kunye neenyawo ezishiywe ngabahlaseli njengoko besebenza kwiinkqubo nakwiinethiwekhi.

-Ulwazi lwesicelo kunye nosongelo
Ukufunyanwa kwangethuba kobuthathaka kunokunciphisa ukulahleka kolwazi oluyimfihlo kunye neendleko zobuthathaka ekugqibeleni. Ukubonakala okuqaphelekayo okubonelelwa yi-NPB kungasetyenziselwa ukutyhila imilinganiselo yokungena (i-IOC), ukuchonga indawo yeendawo ze-vectors zohlaselo, kunye nokulwa neengozi ze-cryptographic.

Ubukrelekrele besicelo budlula umaleko wesi-2 ukuya kumaleko wesi-4 (imodeli ye-OSI) yedatha yepakethi ukuya kumaleko wesi-7 (umaleko wesicelo). Idatha etyebileyo malunga nabasebenzisi kunye nokuziphatha kwesicelo kunye nendawo inokudalwa kwaye ithunyelwe ngaphandle ukuze kuthintelwe ukuhlaselwa kwinqanaba lesicelo apho ikhowudi enobungozi izenza ngathi yidatha eqhelekileyo kunye nezicelo zabathengi ezisebenzayo.
Ukubona okucacileyo ngemeko kunceda ukubona usetyenziso olunobungozi olusebenza kwinethiwekhi yakho kunye neenyawo ezishiywe ngabahlaseli njengoko besebenza kwiinkqubo nakwiinethiwekhi.

-Ukusetyenziswa kokubeka esweni inethiwekhi
Ukubonakala okuqaphelayo kwizicelo nako kunempembelelo enkulu ekusebenzeni nasekulawuleni. Ungafuna ukwazi xa umqeshwa ESEBENZISA inkonzo esekwe kwilifu efana neDropbox okanye i-imeyile esekwe kwiwebhu ukuze adlule imigaqo-nkqubo yokhuseleko kunye nokudlulisa iifayile zenkampani, okanye xa umqeshwa wangaphambili ezama ukufikelela kwiifayile esebenzisa inkonzo yokugcina izinto esekwe kwilifu.
