Amanethiwekhi wangasese abonakalayo (VPNs) ngokuvamile abhekwa njengesivikelo esinamandla sokuxhumana kwedatha. Yiziphi ubuchwepheshe bokuphepha be-VPN?
Okuthiwa i-VPN ephephile inikeza kokubili ukuqinisekiswa kwenethiwekhi nokubhala. Ama-VPN avikelekile avame ukusetshenziswa kabanzi usebenzisa i- IPsec noma i- SSL .
Ukusebenzisa i-IPsec ye-VPN Security
I-IPsec ibe yisenzo sendabuko sokusebenzisa ukuphepha kwe-VPN kumanethiwekhi ezinkampani. Imishini yenethiwekhi yezinkampani ezivela ezinkampanini ezinjengeCisco noJuniper zenza imisebenzi ye-VPN ebalulekile ye-hardware. Isofthiwe yeklayenti ehambelana ne-VPN isetshenziselwa ukungena kwinethiwekhi. I-IPsec isebenza kwendlalelo engu-3 (i-layer layer) ye- OSI model .
Ukusebenzisa i-SSL ye-VPN Security
I-SSL VPNs iyindlela ehlukile ku-IPsec encike kusiphequluli seWebhu esikhundleni samakhasimende we-VPN wangokwezifiso ukungena kwinethiwekhi yangasese. Ngokusebenzisa izivumelwano zenethiwekhi ye-SSL ezakhiwe ngeziphequluli ezijwayelekile zeWeb kanye namaseva weWeb, ama-SSL VPN ahloswe ukuba ashibhile ukusetha nokulondoloza kune-IPsec VPNs. Ukwengeza, i-SSL isebenza ezingeni eliphakeme kune-IPsec, inikeza abaphathi izinketho ezingaphezulu zokulawula ukufinyelela kunsizakalo zenethiwekhi. Kodwa-ke, ukumisa i-SSL VPNs ukuze kukhonjiswe ngezinsiza ezingatholakali ngokuvamile kusuka kusiphequluli seWebhu kungaba nzima.
I-Wi-Fi vs. VPN Security
Ezinye izinhlangano zisebenzisa iPsec (noma ngezinye izikhathi SSL) VPN ukuvikela inethiwekhi yendawo ye-Wi-Fi . Eqinisweni, izivumelwano zokuphepha ze-Wi-Fi njenge-WPA2 ne-WPA-AES zenzelwe ukusekela ukuqinisekiswa okudingekayo nokubethela ngaphandle kwesidingo sokusekelwa kwe-VPN.
