Tsamba Lachinyengo Kuti Mumvetsetse Ma Protocol a VPN

Muyenera kuti mudamvapo zama protocol osiyanasiyana mukamagwiritsa ntchito ma VPN. Ambiri atha kukupangirani OpenVPN pomwe ena akuganiza kuti muyese PPTP kapena L2TP. Komabe, ambiri mwa ogwiritsa ntchito VPN samamvetsetsabe kuti ma protocol awa ndi chiyani, amagwira ntchito bwanji, komanso angachite chiyani.

Chifukwa chake, kuti zinthu zizikhala zosavuta kwa inu nonse, takonza tsamba lachinyengo la VPN protocol momwe mungapezere a kufananiza ma protocol a VPN pamodzi ndi mfundo zofunika za aliyense wa iwo. Tiyika zolozera zachidule tisanayambe, chifukwa zithandiza omwe akufuna mayankho mwachangu.

Chidule Chachangu:

• Nthawi zonse sankhani OpenVPN popeza ndiye VPN yodalirika kwambiri pa liwiro komanso chitetezo.
• L2TP ndiye njira yachiwiri yabwino kwambiri ndipo imagwiritsidwa ntchito ndi ogwiritsa ntchito ambiri a VPN.
• Kenako pamabwera SSTP yomwe imadziwika ndi chitetezo chake chabwino koma simungayembekezere kuthamanga kwabwino konse.
• PPTP ndiye njira yomaliza makamaka chifukwa cha zolakwika zake zachitetezo. Komabe, ndi imodzi mwama VPN othamanga kwambiri komanso osavuta kugwiritsa ntchito.

VPN Protocol Cheat Sheet

Tsopano tifotokoza ma protocol onse a VPN payekhapayekha, kuti mutha kuphunzira zonse za iwo m'njira yosavuta kumvetsetsa:

OpenVPN

OpenVPN ndi protocol yotseguka. Ndiwosinthika kwambiri ndipo imabwera pamasinthidwe amitundu yosiyanasiyana ndi ma encryption. Komanso, zatsimikiziridwa kuti ndizodalirika komanso zotetezeka VPN protocol kunja uko.

Gwiritsani ntchito: Popeza ndi gwero lotseguka, OpenVPN imagwiritsidwa ntchito kwambiri ndi makasitomala achitatu a VPN. Protocol ya OpenVPN sinapangidwe pamakompyuta ndi zida zam'manja. Komabe, ikukhala yotchuka kwambiri ndipo tsopano ndi protocol yokhazikika ya VPN ya mautumiki ambiri a VPN.

Liwiro: Protocol ya OpenVPN si njira yachangu kwambiri ya VPN, koma poganizira zachitetezo chomwe amapereka, liwiro lake ndilabwino kwambiri.

Chitetezo: OpenVPN protocol ndi imodzi mwama protocol otetezedwa kwambiri. Imagwiritsa ntchito protocol yachitetezo yomwe idakhazikitsidwa ndi OpenSSL. Ndibwinonso kwambiri pankhani ya VPN yobisika chifukwa imatha kusinthika pa doko lililonse, kotero imatha kubisa mosavuta kuchuluka kwa VPN ngati kuchuluka kwa intaneti. Ma algorithms ambiri a encryption amathandizidwa ndi OpenVPN omwe akuphatikizapo Blowfish ndi AES, awiri mwa omwe amapezeka kwambiri.

Kusavuta Kukonzekera: Kukonzekera kwamanja kwa OpenVPN sikophweka konse. Komabe, simuyenera kuyikonza pamanja chifukwa makasitomala ambiri a VPN ali kale ndi OpenVPN protocol yokhazikitsidwa. Chifukwa chake, ndiyosavuta kugwiritsa ntchito kudzera pa kasitomala wa VPN ndikukonda.

L2TP

Layer 2 Tunnel Protocol kapena L2TP ndi njira yolumikizira yomwe nthawi zambiri imalumikizidwa ndi protocol ina yachitetezo kuti ipereke kubisa ndi kuvomereza. L2TP ndi imodzi mwama protocol osavuta kuphatikiza ndipo idapangidwa ndi Microsoft ndi Cisco.

Gwiritsani ntchito : Imathandiza kupeza intaneti motetezeka komanso mwachinsinsi kudzera pa VPN chifukwa chakuwongolera kwake komanso chilolezo chachitetezo cha chipani chachitatu.

Liwiro: Pankhani ya liwiro, ndiyabwino kwambiri ndipo imakhala yachangu ngati OpenVPN. Komabe, mukayerekeza, onse OpenVPN ndi L2TP ndi ochedwa kuposa PPTP.

Chitetezo: Protocol ya L2TP sipereka kubisa kapena chilolezo chokha. Komabe, itha kuphatikizidwa ndi mitundu ingapo ya ma encryption ndi ma aligorivimu ovomerezeka. Nthawi zambiri, IPSec imaphatikizidwa ndi L2TP zomwe zimadzetsa nkhawa kwa ena monga momwe NSA idathandizira kupanga IPSec.

Kusavuta Kukonzekera: L2TP imagwira ntchito ndi zida zambiri monga ambiri tsopano ali ndi chithandizo cha L2TP protocol. Kukhazikitsa kwa L2TP ndikosavuta. Komabe, doko lomwe protocol iyi imagwiritsa ntchito imatsekedwa mosavuta ndi ma firewall ambiri. Chifukwa chake, kuti muwazungulire, wogwiritsa ntchito ayenera kugwiritsa ntchito kutumiza padoko komwe kumafuna kukhazikitsidwa kovutirapo.

PPTP

Kuwongolera kwa Point-to-Point kapena komwe kumadziwika kuti PPTP ndiye yakale kwambiri komanso imodzi mwamapulogalamu odziwika kwambiri a VPN. Idapangidwa koyamba ndi Microsoft.

Gwiritsani ntchito: PPTP VPN protocol imagwiritsidwa ntchito pa intaneti komanso pa intaneti. Zikutanthauza kuti mutha kugwiritsanso ntchito protocol kuti mupeze maukonde amakampani kuchokera kumalo akutali.

Liwiro: Popeza PPTP imagwiritsa ntchito njira yochepetsera kubisa imapereka liwiro lodabwitsa. Ichi ndi chifukwa chachikulu chomwe chiri chofulumira kwambiri VPN protocol pakati pa onse.

Chitetezo: Pankhani ya chitetezo, PPTP ndiye njira yodalirika kwambiri ya VPN popeza imapereka mulingo wotsikitsitsa wachinsinsi. Kuphatikiza apo, pali zofooka zosiyanasiyana mu protocol ya VPN iyi yomwe imapangitsa kuti ikhale yotetezeka kwambiri kugwiritsa ntchito. M'malo mwake, ngati mumasamala zachinsinsi chanu ndi chitetezo pang'ono, simuyenera kugwiritsa ntchito protocol iyi ya VPN.

Kusavuta Kukonzekera: Popeza ndi protocol yakale kwambiri komanso yodziwika bwino ya VPN, ndiyosavuta Kukhazikitsa ndipo pafupifupi zida zonse ndi makina amapereka chithandizo chokhazikika cha PPTP. Ndi imodzi mwama protocol osavuta a VPN potengera kasinthidwe ka zida zosiyanasiyana.

Mtengo wa STP

SSTP kapena Secure Socket Tunneling Protocol ndi ukadaulo wa eni omwe adapangidwa ndi Microsoft. Idapangidwa koyamba mu Windows Vista. SSTP imagwiranso ntchito pamakina a Linux, koma idamangidwa kuti ikhale ukadaulo wa Windows okha.

Gwiritsani ntchito: SSTP si njira yothandiza kwambiri. Ndiwotetezeka kwambiri ndipo imatha kuzungulira ma firewall popanda zovuta kapena zovuta. Komabe, imagwiritsidwa ntchito kwambiri ndi mafani a Windows olimba ndipo ilibe mwayi pa OpenVPN, chifukwa chake OpenVPN imalimbikitsidwa.

Liwiro: Pankhani ya liwiro, sikuthamanga kwambiri chifukwa imapereka chitetezo champhamvu komanso kubisa.

Chitetezo: SSTP imagwiritsa ntchito kubisa kwa AES mwamphamvu. Kuphatikiza apo, ngati mukugwiritsa ntchito Windows, ndiye kuti SSTP ndiye njira yotetezeka kwambiri yomwe mungagwiritse ntchito.

Kusavuta Kukonzekera: Ndikosavuta kukhazikitsa SSTP pamakina a Windows, koma ndizovuta pamakina a Linux. Mac OSx sichigwirizana ndi SSTP ndipo mwina sichidzatero.

IKEv2

Internet Key Exchange version 2 ndi IPSec yochokera ku tunneling protocol yomwe inapangidwa ndi Cisco ndi Microsoft pamodzi.

Gwiritsani ntchito: Amagwiritsidwa ntchito kwambiri pazida zam'manja chifukwa chanzeru zake zolumikiziranso. Mauthenga am'manja am'manja nthawi zambiri amasiya maulalo omwe IKEv2 amakhala othandiza kwambiri. Thandizo la protocol ya IKEv2 likupezeka pazida za Blackberry.

Liwiro: IKEv2 ndiyothamanga kwambiri.

Chitetezo: IKEv2 imathandizira magawo osiyanasiyana a AES encryption. Palinso mitundu ina yotseguka ya IKEv2 yomwe iliponso, kotero ogwiritsa ntchito atha kupewa mtundu wa Microsoft.

Kusavuta Kukonzekera: Si protocol ya VPN yogwirizana kwambiri chifukwa pali zida zochepa zomwe zimathandizira. Komabe, pazida zofananira, ndizosavuta kukonza.

Mawu Omaliza

Chifukwa chake izi ndizo zonse zomwe muyenera kudziwa za ma protocol ambiri a VPN. Tikukhulupirira kuti tsamba lathu lofananiza ma protocol a VPN lakhala lothandiza komanso lothandiza kwa inu. Tiuzeni ngati muli ndi mafunso ena okhudza ma protocol omwe ali mugawo la ndemanga pansipa.
