Iintanethi zangasese ezizimeleyo (i-VPNs) ngokuqhelekileyo ziqwalaselwe ukuba zikhuselekile kakhulu kunxibelelwano lweedatha. Ziziphi iimpawu zobuchwephesha ze-VPN?
Ezibizwa ngokuba yi-VPNs ezikhuselekileyo zinika zombini ukuqinisekiswa kwenethiwekhi kunye nokubhala. IiVPN ezikhuselekileyo zivame ukusetyenziswa ngokusetyenziswa kwe- IPsec okanye i- SSL .
Ukusebenzisa iPsec kwi-VPN Security
I-IPsec ibe yinto ekhethekileyo yokusebenzisa ukukhuselwa kwe-VPN kumanethiwekhi enkampani. Iifowuni zeekhanekhthi zentengiso yeenkampani ezivela kwiinkampani ezifana neCisco neJuniper zizalisekisa imisebenzi ebalulekileyo ye-VPN iseva kwi-hardware. Isoftware ye-VPN isetyenziselwa ukungena kwi-intanethi. I-IP isebenza kwinqanaba elingu-3 (Uluhlu lweNethiwekhi) lwe- OSI .
Ukusebenzisa i-SSL ye-VPN Security
I-SSL VPN yindlela ehlukile kwi-IPs ethembela kwisiphequluli seWebhu endaweni ye-client VPN. Ngokusebenzisa iiprotokholi zenethiwekhi ze-SSL ezakhiweyo kwiiskrini zewebhu kunye nee-Web server, ii-SSL VPN zenzelwe ukuba zingabizi ukusetha nokugcina kune-IPsec VPNs. Ukongezelela, i-SSL isebenza kwinqanaba eliphakamileyo kune-IPsec, inika abalawuli ithuba elininzi lokulawula ukufikelela kwizixhobo zonxibelelwano. Nangona kunjalo, ukuqwalasela i-SSL VPNs ukujongana nezixhobo ezingaqhelekanga kufumaneka kwi-Web browser.
Wi-Fi vs. VPN Security
Enye imibutho isebenzisa i-IPsec (okanye ngamanye ama-SSL) i-VPN ukukhusela inethiwekhi yendawo ye -Wi-Fi . Enyanisweni, iiprotokholi ze-Wi-Fi ezifana ne-WPA2 kunye ne-WPA-AES zenzelwe ukuxhasa ukuqinisekiswa okufunekayo kunye nokubhalwa kwemfihlo ngaphandle kwemfuneko yenkxaso ye-VPN.
