Kuonetsetsa kuti ma network ali otetezeka m'malo osinthika mwachangu a IT komanso kusintha kosalekeza kwa ogwiritsa ntchito kumafuna zida zambiri zapamwamba kuti azitha kusanthula nthawi yeniyeni. Malo anu owunikira akhoza kukhala ndi ma network ndi ma application performance monitoring (NPM/APM), deta loggers, ndi ma network analyzers achikhalidwe, pomwe ma network anu oteteza amagwiritsa ntchito ma firewall, intrusion protection systems (IPS), data leak protection (DLP), anti-malware, ndi njira zina zothetsera vutoli.
Kaya zida zachitetezo ndi zowunikira zili zapadera bwanji, zonse zili ndi zinthu ziwiri zofanana:
• Ndikufunika kudziwa bwino zomwe zikuchitika mu netiweki
• Zotsatira za kusanthula zimachokera pa deta yomwe yalandiridwa yokha
Kafukufuku wochitidwa ndi Enterprise Management Association (EMA) mu 2016 adapeza kuti pafupifupi 30% ya omwe adayankha sanakhulupirire zida zawo kuti zilandire deta yonse yomwe amafunikira. Izi zikutanthauza kuti pali kuyang'anira malo osawoneka bwino mu netiweki, zomwe pamapeto pake zimapangitsa kuti khama lisaphule kanthu, ndalama zambiri, komanso chiopsezo chachikulu cha kubedwa.
Kuwonekera kumafuna kupewa kuwononga ndalama ndi kuyang'anira malo osawoneka bwino pa intaneti, zomwe zimafuna kusonkhanitsa deta yoyenera pa chilichonse chomwe chikuchitika mu netiweki. Ma splitters/splitters ndi ma mirror ports a zida za netiweki, omwe amadziwikanso kuti ma SPAN ports, amakhala malo olowera omwe amagwiritsidwa ntchito kujambula anthu kuti awunike.
Iyi ndi "ntchito yosavuta"; vuto lenileni ndikutumiza deta kuchokera ku netiweki kupita ku chida chilichonse chomwe chikufunikira. Ngati muli ndi magawo ochepa a netiweki ndi zida zochepa zowunikira, ziwirizi zitha kulumikizidwa mwachindunji. Komabe, poganizira liwiro lomwe ma netiweki amapitilira kukula, ngakhale zitakhala zotheka, pali mwayi waukulu kuti kulumikizana kwa munthu ndi munthu kudzapanga vuto lalikulu loyang'anira.
EMA inanena kuti 35% ya mabungwe amakampani adatchula kusowa kwa madoko a SPAN ndi ma splitter ngati chifukwa chachikulu chomwe adalephera kuyang'anira mokwanira magawo awo a netiweki. Madoko omwe ali pazida zowunikira zapamwamba monga ma firewall nawonso ndi osowa, kotero ndikofunikira kuti musawonjezere zida zanu ndikuchepetsa magwiridwe antchito.
Nchifukwa chiyani mukufunika Network Packet Brokers?
Network Packet Broker (NPB) imayikidwa pakati pa ma splitter kapena ma SPAN ports omwe amagwiritsidwa ntchito kupeza deta ya netiweki, komanso zida zachitetezo ndi zowunikira. Monga momwe dzinalo likusonyezera, ntchito yayikulu ya network packet broker ndi: kugwirizanitsa deta ya netiweki kuti zitsimikizire kuti chida chilichonse chowunikira chimapeza molondola deta yomwe chikufunikira.
NPB imawonjezera chidziwitso chofunikira kwambiri chomwe chimachepetsa mtengo ndi zovuta, zomwe zimakuthandizani kuti:
Kuti mupeze deta yokwanira komanso yolondola kuti mupange zisankho zabwino
Wogulitsa mapaketi a pa intaneti wokhala ndi luso losefera lapamwamba amagwiritsidwa ntchito popereka deta yolondola komanso yothandiza pazida zanu zowunikira komanso kusanthula chitetezo.
Chitetezo cholimba
Ngati simungathe kuzindikira chiwopsezo, zimakhala zovuta kuchiletsa. NPB idapangidwa kuti iwonetsetse kuti ma firewall, IPS, ndi makina ena oteteza nthawi zonse amakhala ndi chidziwitso cholondola chomwe amafunikira.
Konzani mavuto mwachangu
Ndipotu, kungodziwa vutoli kumachititsa 85% ya MTTR. Nthawi yopuma imatanthauza kutayika kwa ndalama, ndipo kusagwiritsa ntchito bwino ndalamazo kungakhudze bizinesi yanu kwambiri.
Kusefa kodziwa bwino nkhani komwe kumaperekedwa ndi NPB kumakuthandizani kupeza ndi kuzindikira chomwe chimayambitsa mavuto mwachangu mwa kuyambitsa nzeru zapamwamba za mapulogalamu.
Wonjezerani mphamvu
Metadata yoperekedwa ndi NPB yanzeru kudzera mu NetFlow imathandizanso kupeza deta yodalirika kuti iyang'anire kagwiritsidwe ntchito ka bandwidth, zomwe zikuchitika, komanso kukula kuti athetse vutoli pachiyambi.
Phindu labwino pa ndalama zomwe zayikidwa
Smart NPB sikuti imangosonkhanitsa anthu kuchokera ku malo owunikira monga ma switch, komanso kusefa ndi kusonkhanitsa deta kuti iwonjezere kugwiritsa ntchito ndi kupanga bwino zida zachitetezo ndi zowunikira. Mwa kungoyang'anira anthu ofunikira okha, titha kukonza magwiridwe antchito a zida, kuchepetsa kuchulukana kwa anthu, kuchepetsa zabwino zabodza, komanso kupeza chitetezo chokwanira pogwiritsa ntchito zida zochepa.
Njira zisanu zowonjezerera phindu la ndalama pogwiritsa ntchito Network Packet Brokers:
• Kuthetsa mavuto mwachangu
• Kuzindikira zofooka mwachangu
• Kuchepetsa katundu wa zida zachitetezo
• Kukulitsa moyo wa zida zowunikira panthawi yokonzanso
• Kuchepetsa kutsata malamulo
Kodi kwenikweni NPB ingachite chiyani?
Kusonkhanitsa, kusefa, ndi kupereka deta kumamveka kosavuta m'malingaliro. Koma kwenikweni, NPB yanzeru imatha kugwira ntchito zovuta kwambiri, zomwe zimapangitsa kuti magwiridwe antchito komanso chitetezo chikhale chokwera kwambiri.
Kuchuluka kwa magalimoto ndi chimodzi mwa ntchito zake. Mwachitsanzo, ngati mukukweza netiweki yanu ya data center kuchokera pa 1Gbps kufika pa 10Gbps, 40Gbps, kapena kupitirira apo, NPB ikhoza kuchepetsa liwiro kuti ipereke kuchuluka kwa magalimoto othamanga kwambiri ku zida zowunikira zotsika mtengo za 1G kapena 2G. Izi sizimangowonjezera phindu la ndalama zomwe mwayika pakali pano, komanso zimapewa kusintha kokwera mtengo pamene IT yasamutsidwa.
Zinthu zina zamphamvu zomwe NPB imachita ndi izi:
Mapaketi a data osafunikira achotsedwa
Zipangizo zowunikira ndi chitetezo zimathandiza kulandira mapaketi ambiri obwerezabwereza otumizidwa kuchokera ku ma splitter angapo. NPB imatha kuthetsa kubwerezabwereza kuti zida zisawononge mphamvu yogwiritsira ntchito pokonza deta yofunikira.
Kuchotsa Kubisa kwa SSL
Kubisa kwa Secure Socket Layer (SSL) ndi njira yodziwika bwino yomwe imagwiritsidwa ntchito potumiza zambiri zachinsinsi mosamala. Komabe, akuba amathanso kubisa ziwopsezo zoyipa za pa intaneti m'maphukusi obisika.
Kufufuza deta iyi kuyenera kuchotsedwa, koma kuchotsedwa kwa code kumafuna mphamvu yamtengo wapatali yogwiritsira ntchito. Opanga mapaketi otsogola amatha kutsitsa kuchotsedwa kwa deta kuchokera ku zida zachitetezo kuti atsimikizire kuwonekera bwino pomwe akuchepetsa katundu pazinthu zodula.
Kubisa Deta
Kuchotsa deta ya SSL kumapangitsa kuti detayo iwonekere kwa aliyense amene ali ndi mwayi wopeza zida zachitetezo ndi zowunikira. NPB ikhoza kuletsa manambala a kirediti kadi kapena Social Security, zambiri zaumoyo zotetezedwa (PHI), kapena zina zodziwika bwino (PII) musanapereke chidziwitsocho, kuti chisaululidwe kwa chida ndi oyang'anira ake.
Kuchotsa Mutu
NPB ikhoza kuchotsa mitu monga VLAN, VXLAN, L3VPN, kotero zida zomwe sizingathe kuthana ndi ma protocol awa zimatha kulandira ndikukonza deta ya phukusi. Kuwona bwino momwe zinthu zilili kumathandiza kupeza mapulogalamu oipa omwe akuyenda pa netiweki ndi mapazi omwe atsala ndi owukira pamene akugwira ntchito mu dongosolo ndi netiweki.
Chidziwitso cha kugwiritsa ntchito ndi kuopseza
Kuzindikira msanga za zofooka kumachepetsa kutayika kwa chidziwitso chachinsinsi komanso ndalama zomwe zimawononga zofooka. Kuwona bwino komwe kumaperekedwa ndi NPB kungagwiritsidwe ntchito kuvumbulutsa zizindikiro za kulowerera (IOC), kuzindikira malo omwe ma vectors akuukira ali, komanso kuthana ndi ziwopsezo za cryptographic.
Luntha la mapulogalamu limapitirira magawo 2 mpaka 4 (OSI model) a deta ya paketi mpaka gawo 7 (gawo la mapulogalamu). Deta yochuluka pa khalidwe la ogwiritsa ntchito ndi mapulogalamu ndi malo ake ikhoza kupangidwa ndikutumizidwa kunja kuti ipewe kuukira kwa magawo a mapulogalamu pomwe ma code oyipa amaoneka ngati deta yachibadwa komanso zopempha za makasitomala zovomerezeka.
Kuwona bwino momwe zinthu zilili kumathandiza kupeza mapulogalamu oipa omwe akuyenda pa netiweki yanu komanso mapazi omwe akusiyidwa ndi owukira akamagwira ntchito kudzera mu dongosolo lanu ndi netiweki yanu.
Kuwunika Ntchito
Kuwonekera kwa momwe mapulogalamu amagwirira ntchito kumakhudzanso kwambiri magwiridwe antchito ndi kasamalidwe. Mwina mukufuna kudziwa nthawi yomwe antchito adagwiritsa ntchito mautumiki ozikidwa pa mtambo monga Dropbox kapena maimelo ozikidwa pa intaneti kuti apewe mfundo zachitetezo ndikusamutsa mafayilo a kampani, kapena nthawi yomwe antchito akale adayesa kupeza mafayilo pogwiritsa ntchito mautumiki osungira zinthu pa intaneti ozikidwa pa mtambo.
Ubwino wa NPB
• Yosavuta kugwiritsa ntchito ndi kuyang'anira
• Luntha lochotsa mavuto a gulu
• Palibe kutayika kwa paketi - ili ndi zinthu zapamwamba
• Kudalirika 100%
• Kapangidwe kabwino kwambiri
