Ishidi Lokukhohlisa Lokuqonda Izivumelwano ze-VPN

Kufanele ngabe uzwile ngezivumelwano ezahlukahlukene ngenkathi usebenzisa ama-VPN. Abaningi kungenzeka ukuthi bancome i-OpenVPN kuwe ngenkathi abanye kungenzeka ukuthi baphakamise ukuthi bazame i-PPTP noma i-L2TP. Kodwa-ke, iningi labasebenzisi be-VPN alikaqondi ukuthi ziyini lezi zinqubo, zisebenza kanjani, futhi zingenzani.

Okuqukethwe umbukiso 1 Ishidi Lokukhohlisa le-VPN 1.1 VulaVPN 1.2 I-L2TP 1.3 I-PPTP 1.4 SSTP 1.5 IKEv2

Ngakho-ke, ukwenza izinto zibe lula kini nonke, silungiselele leli phepha lokukhohlisa le-VPN lapho uzothola khona ukuqhathaniswa kwezivumelwano ze-VPN kanye nemininingwane ebalulekile ngalowo nalowo wabo. Sizobeka izikhombisi ezifingqiwe ngaphambi kokuba siqale, ngoba kuzosiza labo abafuna izimpendulo ezisheshayo.



Isifinyezo Esisheshayo:



  • Ngaso sonke isikhathi khetha i-OpenVPN njengoba iyi-VPN ethembeke kakhulu ngokwejubane nokuphepha.
  • I-L2TP iyindlela yesibili engcono kakhulu futhi isetshenziswa kakhulu ngabasebenzisi abaningi be-VPN.
  • Bese kulandela i-SSTP eyaziwa ngokuvikeleka kwayo okuhle kepha awukwazi ukulindela isivinini esihle kuyo nakancane.
  • I-PPTP iyisinqumo sokugcina ikakhulukazi ngenxa yamaphutha ezokuphepha. Kodwa-ke, ingenye yezivumelwano ze-VPN ezisheshayo futhi ezilula kakhulu ongazisebenzisa.

Ishidi Lokukhohlisa le-VPN

Manje sizochaza ngayinye yezivumelwano ze-VPN ngawodwana, ngakho-ke ungafunda konke ngazo ngendlela eqondakala kalula:

VulaVPN

VulaVPN umthetho olandelwayo ovulekile. Kuyinto nezimo ngokwedlulele uma kuziwa ukucupha on ahlukahlukene emachwebeni kanye ukubethela izinhlobo. Ngaphezu kwalokho, kufakazelwe ukuthi kuyiprotocol ethembeke kakhulu futhi evikelekile ye-VPN laphaya.



Sebenzisa: Njengoba ingumthombo ovulekile, i-OpenVPN isetshenziswa kakhulu ngamakhasimende wesithathu e-VPN. Iphrothokholi ye-OpenVPN ayakhelwe kumakhompyutha nakumadivayisi eselula. Kodwa-ke, kuya ngokuya kuthandwa kakhulu futhi manje sekuyiprothokholi ye-VPN ezenzakalelayo yezinsizakalo eziningi ze-VPN.

izilungiselelo ze-windows 10 azivuli i-2019

Ijubane: Iphrothokholi ye-OpenVPN akuyona inqubo esheshayo ye-VPN, kepha uma ubheka izinga lezokuphepha elinikezayo, ijubane layo lihle impela.

Ukuphepha: Iphrothokholi ye-OpenVPN ingenye yezivumelwano ezivikeleke kakhulu. Isebenzisa umthetho olandelwayo wokuphepha kwamakhasimende osuselwa ku-OpenSSL. Kuhle futhi maqondana ne-stealth VPN ngoba iyalungiswa kunoma iyiphi itheku, ngakho-ke ingafihla kalula ithrafikhi ye-VPN njengokujwayelekile kwe-intanethi. Ama-algorithm amaningi wokubethela asekelwa yi-OpenVPN okubandakanya i-Blowfish ne-AES, okubili okuvame kakhulu.



Ukulula Kokumiswa: Ukuhlelwa okwenziwa ngesandla kwe-OpenVPN akulula neze. Kodwa-ke, akudingeki ukuthi uyilungiselele ngesandla ngoba amaklayenti amaningi we-VPN asevele enenqubo elandelwayo ye-OpenVPN. Ngakho-ke, kulula ukuyisebenzisa ngeklayenti le-VPN futhi uncamela.

I-L2TP

I-Layer 2 Tunnel Protocol noma i-L2TP iyi-tunneling protocol evame ukumataniswa nenye inqubo yokuphepha yokunikeza ukubethela nokugunyazwa. I-L2TP ingenye ye-protocol elula ukuyihlanganisa futhi yathuthukiswa yi-Microsoft ne-Cisco.

Sebenzisa : Kuyasiza ekutholeni i-intanethi ngokuphepha nangasese nge-VPN ngenxa yokuthungwa kwayo nokugunyazwa kokuphepha komuntu wesithathu.

Ijubane: Ngokuya ngejubane, empeleni inekhono futhi icishe isheshe njenge-OpenVPN. Kodwa-ke, uma uqhathanisa, womabili ama-OpenVPN ne-L2TP ahamba kancane kune-PPTP.

ukufinyelela kunqatshelwe ukungakwazi ukuxhuma amawindi ephrinta 10

Ukuphepha: Iphrothokholi ye-L2TP ayinikeli noma yikuphi ukubethela noma ukugunyazwa kukodwa. Noma kunjalo, ingahlanganiswa nezinhlobonhlobo zokubethela nokugunyaza ama-algorithms. Ngokuvamile, i-IPSec ihambisana ne-L2TP ephakamisa ukukhathazeka kwabanye njengoba i-NSA isize ekwakheni i-IPSec.

Ukulula Kokumiswa: I-L2TP iyahambisana namadivayisi amaningi njengoba iningi manje selinokusekelwa okwakhelwe ngaphakathi kwe-L2TP protocol. Inqubo yokusetha ye-L2TP nayo ilula kakhulu. Kodwa-ke, itheku elisetshenziswa yilo mthetho olandelwayo livinjwe kalula yizicishamlilo eziningi. Ngakho-ke, ukuze ubazungeze, umsebenzisi udinga ukusebenzisa ukudluliselwa kwembobo okudinga ukusethwa okuyinkimbinkimbi ngokwengeziwe.

I-PPTP

Ukudonswa kwePoint-to-Point noma okwaziwa kakhulu njenge-PPTP yindala endala futhi ingenye yephrothokholi ethandwa kakhulu ye-VPN. Yakhiwe ekuqaleni yi-Microsoft.

Sebenzisa: I-PPTP VPN protocol isetshenziselwa womabili amanethiwekhi we-inthanethi kanye ne-intranet. Kusho ukuthi ungasebenzisa futhi umthetho olandelwayo ukufinyelela inethiwekhi yenkampani kusuka endaweni ekude.

Ijubane: Njengoba i-PPTP isebenzisa ukubethela okuphansi okujwayelekile kunikeza isivinini esimangazayo. Lesi yisona sizathu esikhulu esenza kube yiprotocol esheshayo ye-VPN phakathi kwakho konke.

amawindi ayi-10 anamathele kuma-99

Ukuphepha: Ngokuphepha, i-PPTP yiphrothokholi ye-VPN ethembeke kakhulu njengoba inikela ngezinga lokubethela eliphansi kunawo wonke. Ngaphezu kwalokho, kukhona ukuthikamezeka okuhlukahlukene kule protocol ye-VPN eyenza ukuthi kube ephephe kunazo zonke ongayisebenzisa. Eqinisweni, uma ubakhathalele ubumfihlo bakho nokuvikeleka okukodwa, akufanele usebenzise le protocol ye-VPN.

Ukulula Kokumiswa: Njengoba kuyiphrothokholi endala futhi ejwayeleke kakhulu ye-VPN, kulula ukusetha futhi cishe wonke amadivayisi nezinhlelo zinikela ngokusekelwa okwakhelwe ngaphakathi kwe-PPTP. Ingenye yezivumelwano ezilula ze-VPN maqondana nokucushwa kwamadivayisi ahlukahlukene.

misa izibuyekezo ezizenzakalelayo windows 10 ekhaya

SSTP

SSTP noma Protocol Socket Tunneling ubuchwepheshe bokuthengisa obakhiwa i-Microsoft. Iqale yakhelwa kwiWindows Vista. I-SSTP nayo isebenza kumasistimu asuselwa ku-Linux, kepha yayakhelwe kakhulu ubuchwepheshe be-Windows kuphela.

Sebenzisa: I-SSTP akuyona inqubo elusizo kakhulu. Impela iphephe kakhulu futhi ingazungeza izingodo zomlilo ngaphandle kokuhlupheka noma ubunzima. Noma kunjalo, isetshenziswa kakhulu ngabalandeli be-hardcore Windows futhi ayinayo inzuzo kune-OpenVPN, yingakho i-OpenVPN inconywa.

Ijubane: Ngokuya ngejubane, akusheshi kakhulu njengoba inikeza ukuphepha okunamandla nokubethela.

Ukuphepha: I-SSTP isebenzisa ukubethela okuqinile kwe-AES. Ngokwengeziwe, uma usebenzisa iWindows, khona-ke i-SSTP yiprothokholi ephephe kunazo zonke ongayisebenzisa.

Ukulula Kokumiswa: Kulula kakhulu ukusetha i-SSTP kumishini ye-Windows, kepha kunzima kuma-Linux based systems. IMac OSx ayisekeli i-SSTP futhi mhlawumbe ngeke ize.

IKEv2

I-Internet Key Exchange version 2 iyi-IPSec based tunneling protocol eyakhiwe yiCisco neMicrosoft bebonke.

Sebenzisa: Isetshenziswa kakhulu kumadivayisi eselula ngenxa yamakhono ayo amahle wokuxhuma kabusha. Amanethiwekhi wedatha yamaselula avame ukulahla ukuxhumana i-IKEv2 eza kahle kakhulu. Ukusekelwa kwe-protocol ye-IKEv2 kuyatholakala kumadivayisi we-Blackberry.

Ijubane: IKEv2 iyashesha ngokweqile.

Ukuphepha: IKEv2 isekela amazinga ahlukahlukene wokubethela we-AES. Kukhona ezinye izinhlobo zemithombo evulekile ye-IKEv2 etholakalayo futhi, ngakho-ke abasebenzisi bangagwema uhlobo lobunikazi beMicrosoft.

susa ngesandla amafayili wesikhashana windows 10

Ukulula Kokumiswa: Akuyona inqubo ehambisanayo kakhulu ye-VPN njengoba kunamadivayisi alinganiselwe ayisekelayo. Kodwa-ke, kumadivayisi ahambisanayo, kulula kakhulu ukumisa.

Amagama Okugcina

Ngakho-ke yilokhu konke odinga ukukwazi mayelana nezivumelwano ezivame kakhulu ze-VPN. Siyethemba ukuthi iphepha lethu lokukopela lezinhlelo ze-VPN likwazise futhi kwaba wusizo kuwe. Sazise uma uneminye imibuzo mayelana nanoma yiziphi izinqubo ezisesigabeni sokuphawula ngezansi.
