SSL VPN vs IPSec VPN

Nrog rau kev hloov pauv ntawm cov thev naus laus zis sib txuas, kev sib txuas tau nthuav dav hauv ob qho tib si ntiag tug thiab pej xeem. Cov kev sib txuas lus pej xeem thiab ntiag tug no sib txuas lus nrog ntau hom kev tes hauj lwm uas muaj nyob rau hauv ntau yam xws li kev lag luam, tsoom fwv cov koom haum, cov tib neeg thiab lwm yam. Cov kev sib txuas lus no tsis yog ib txwm nyob hauv ib lub network, tuaj yeem muaj ntau lub koom haum pej xeem thiab ntiag tug. Vim li no, kev ruaj ntseg ntawm cov ntaub ntawv xa mus ua lub luag haujlwm tseem ceeb hauv kev sib txuas lus hauv network. Niaj hnub no, chaw ua haujlwm virtualization yog kev siv thev naus laus zis sai, uas cov neeg ua haujlwm tuaj yeem ua haujlwm ntawm lub cev hauv thaj chaw sib txawv. Hauv cov thev naus laus zis zoo li no, cov neeg ua haujlwm tuaj yeem nkag mus rau lawv lub tuam txhab ntiag tug network los ntawm pej xeem network xws li internet. Yog li ntawd, Network Security yog ib qho tseem ceeb rau txhua lub koom haum, Enterprise thiab cov koom haum txhawm rau tiv thaiv cov khoom muaj nqis thiab kev ncaj ncees.

IPSec VPNs

IPSec (Internet Protocol Security) yog cov txheej txheem tsim los ua kom muaj kev ruaj ntseg ntawm cov ntaub ntawv xa los ntawm lub network. Cov txheej txheem no feem ntau yog siv los siv Virtual Private Networks (VPNs). Kev ruaj ntseg yog siv raws li kev lees paub thiab encryption ntawm IP pob ntawv ntawm Network txheej. IPsec yeej txhawb nqa ob txoj kev encryption, Thauj hom thiab Tunnel hom:

hom kev thauj mus los: Tsuas yog Encrypt Payload ntawm IP Pob thiab tsis muaj encryption rau Header feem.

Tunnel hom: Encrypts ob qho tib si Payload thiab Header.

Rau qhov kev pib sib txuas lus tau zoo, IPSec siv kev sib koom ua pov thawj (2 Txoj Kev) cov txheej txheem los tsim kev sib txuas lus thiab kom kev sib txuas lus txuas ntxiv mus, nws qhia tus yuam sij rau pej xeem ntawm kev xa thiab txais cov khoom siv. Qhov kev ua haujlwm no yog ua los ntawm cov txheej txheem hu ua Association thiab Key Management Protocol uas siv cov ntawv pov thawj digital los txheeb xyuas tus neeg txais kev lees paub nrog tus xa.

SSL VPNs

SSL VPN (Secure Sockets Layer Virtual Private Networks) muab tus qauv web browser raws li VPN daws hauv Thawv Txheej. Cov qhov (socket) yog siv los hloov cov ntaub ntawv ntawm tus xa thiab tus txais. Muaj ob hom SSL VPNs.

SSL Portal VPN: Txoj kev no muab kev nyab xeeb rau ntau yam kev pabcuam siv ib tus qauv SSL txuas rau lub vev xaib cuam tshuam. Cov neeg siv khoom tuaj yeem nkag mus rau SSL VPN rooj vag siv lub vev xaib tus qauv, thiab tus neeg siv khoom yuav tsum muab cov ntaub ntawv pov thawj tsim nyog raws li qhov xav tau los ntawm SSL VPN Gateway, txhawm rau txheeb xyuas.

SSL Qhov VPN: Txoj kev no ua rau lub vev xaib browser nkag mus rau ntau qhov kev pabcuam hauv network. Tshwj xeeb tshaj yog txoj kev no txhawb ntau yam kev thov thiab cov txheej txheem uas tej zaum yuav tsis yog web-based. Txhawm rau pab kom SSL Tunnel VPN, lub vev xaib browser yuav tsum muaj peev xwm los tswj cov ntsiab lus nquag.

SSL kev sib txuas lus siv ob tus yuam sij los encrypt cov ntaub ntawv, tus yuam sij rau pej xeem, uas tau muab qhia rau txhua tus, thiab tus yuam sij ntiag tug rau tog txais xwb.

Qhov txawv ntawm IPSec VPN thiab SSL VPN yog dab tsi?

• Feem ntau, IPSec yuav tsum txhim kho IPSec 3rd tog neeg thov Daim Ntawv Thov / Kho vajtse hauv cov neeg siv PC, thiab tus neeg siv yuav tsum pib daim ntawv thov kom pib qhov kev sib txuas ruaj ntseg. Qhov no tuaj yeem cuam tshuam rau lub koom haum nyiaj txiag, vim lawv yuav tsum yuav daim ntawv tso cai rau cov neeg siv VPN no. Tab sis rau SSL VPN, nws tsis tsim nyog rau nruab ib daim ntawv thov cais. Yuav luag txhua tus qauv web browsers niaj hnub tuaj yeem siv SSL Connections.

• Hauv kev sib txuas lus IPSec, ib zaug tus neeg siv khoom tau lees paub rau VPN nws muaj kev nkag mus rau tag nrho ntawm tus kheej network, uas tej zaum yuav tsis tsim nyog, tab sis hauv SSL VPNs, nws muab kev tswj hwm kev nkag tau zoo dua; Thaum pib ntawm SSL authentication, nws tsim qhov tunnels rau cov ntawv thov tshwj xeeb siv cov qhov (sockets) es tsis yog rau tag nrho lub network. Tsis tas li ntawd, qhov no tso cai rau muab lub luag haujlwm raws li kev nkag mus (txoj cai nkag tau sib txawv rau cov neeg siv sib txawv).

• Ib qho tsis zoo ntawm SSL VPN yog tias, peb tuaj yeem siv cov ntawv thov web feem ntau siv SSL VPN. Rau qee cov ntawv thov, txawm hais tias nws tuaj yeem siv los ntawm lub vev xaib ua kom nws ntxiv qee qhov nyuaj rau daim ntawv thov.

• Vim yog muab kev nkag tau tsuas yog rau Web-Enabled Applications, SSL VPN nyuaj rau siv nrog cov ntawv thov xws li kev sib faib cov ntaub ntawv thiab luam ntawv, tab sis IPSec VPNs muab kev ntseeg siab heev rau luam ntawv thiab cov ntaub ntawv sib koom.

• SSL VPNs tau nrov dua vim qhov yooj yim ntawm kev siv thiab kev ntseeg tau tab sis, raws li peb tau hais los saum no, nws tsis ntseeg tau nrog txhua daim ntawv thov. Yog li, xaiv VPN (SSL lossis IPSec) tag nrho nyob ntawm daim ntawv thov thiab cov kev xav tau.
