I-VPN isebenzisa amanxibelelwano othungelwano loluntu ukuqhuba iinkcukacha zoqhagamshelwano lwabucala. Uninzi lweenkqubo ze-VPN zisebenzisa i-Intanethi njengeziseko zikawonkewonke kunye neenkqubo ezahlukeneyo zokuxhasa uxhulumaniso lwabucala nge-Intanethi.
I-VPN ilandele indlela yomsebenzisi kunye neseva. Abaxhasi beVPN baqinisekisile abasebenzisi, babhala idatha, kunye nokulawula ezinye iiseshoni kunye neeseva zeVPN zisebenzisa ubuchule obubizwa ngokuba yi- tunneling .
Abaxhasi beVPN kunye neeseva zeVPN zisetyenziswe kule miba emithathu:
- ukuxhasa ukufikelela okude kwi- intranethi ,
- ukuxhasa uxhulumaniso phakathi kwama-intranethi amaninzi ngaphakathi kwintlangano efanayo, kwaye
- ukujoyina amanethiwekhi phakathi kwemibutho emibini, ukwenza i-extranet.
Inzuzo enkulu ye-VPN yindleko ephantsi efunekayo ukuxhasa le teknoloji xa kuthelekiswa nezinye iindlela ezifana nemigca yemveli eqeshwe okanye iinkonzo zokufikelela ezikude.
Abasebenzisi beVPN baxhamla kunye neenkqubo ezixhamlileyo zabaxhasi. Ezi zicelo zenkxaso ekudaleni imigudu, ukubeka i parameters zokumisela, kunye nokuxhuma kunye nokuxhuma kwi-server yeVPN. Iisombululo ze-VPN zisebenzisa iinkqubo ezahlukeneyo zenethiwekhi eziquka iPPTP, L2TP, IPsec, kunye neSOCKS.
Iiseva zeVPN zinokudibanisa ngqo nakwamanye amaseva eVPN. Unxibelelwano lwe-VPN-server-server luya kwandisa i-intranet okanye i-extranet ukuze isebenze amanethiwekhi amaninzi.
Abathengisi abaninzi baye bavelisa i-VPN hardware kunye neemveliso zesofthiwe. Ezinye zalezi zinto azibandakanyeki ngenxa yokungagcini kwemigangatho ethile yeVPN.
Iincwadi malunga neNgcaciso yeNtanethi yangasese
Ezi ncwadi zininzi ngolwazi kwi-VPN kulabo abangazi kakhulu malunga nale ndaba:
- Iintanethi ezizimeleyo ezizimeleyo: Ukwenza uxhulumano oluchanekileyo (uDennis Fowler) - UMnu. Fowler wabhala lo mboniso ogqwesileyo we-VPNs ngo-1999. Le ncwadi iye yazama ukuvavanya ixesha kwaye ihlala enye yezona zihloko ezibalaseleyo zifuna ukufunda nge-VPN phantsi.
- IiNethwekhi ezizimeleyo ezizimeleyo: ezobuchwepheshe kunye neZisombululo (uRuixi Yuan kunye noW. Timothy Strayer) - uluhlu olubanzi lwe-VPN ngolwazi lwe-tunneling, protocols, kunye ne-PKI lukhutshwa kakuhle kule ngcaciso emfutshane.
