Inethiwekhi yangasese yangasese inikeza uxhumano lwenethiwekhi ngaphezu kwebanga elingase lide ngokomzimba. Kule ndaba, i-VPN yindlela yeWide Area Network . I-VPNs yokwabelana ngefayela, ukuhlanganiswa kwamavidiyo kanye nezinsizakalo zenethiwekhi ezifanayo.
I-VPN ingasebenzisa kokubili amanethiwekhi omphakathi njengama-intanethi namanethiwekhi webhizinisi langasese. Ukusebenzisa indlela ebizwa ngokuthi i-tunneling, i- VPN isebenza phezu kwengqalasizinda efanayo yehadiwe njengama-inthanethi ekhona noma izixhumanisi ze- intranet . Ubuchwepheshe be-VPN buhlanganisa izindlela ezihlukahlukene zokuvikela ukuvikela lezi zixhumanisi ezibonakalayo.
Amanethiwekhi wangasese abonakalayo ngokuvamile awahlinzeki noma yikuphi ukusebenza okusha okungakahlinzekiwe ngezinye izindlela, kodwa i-VPN isebenzisa lezo zinsuku ngokuphumelelayo nangokwamahloni ezimweni eziningi. Ngokuqondile, i-VPN isekela okungenani izindlela ezintathu ezahlukene zokusetshenziswa:
- Ukuxhumeka kwamakhasimende okufinyelela okukude kwe-Inthanethi
- Ukuxhumana phakathi kwe-LAN-to-LAN
- Ukulawulwa okulawulwa ngaphakathi kwe-intranet
I-VPN ye-intanethi yokufinyelela okude
Eminyakeni yamuva, izinhlangano eziningi ziye zandisa ukuhamba kwezisebenzi zazo ngokuvumela abasebenzi abaningi ukuba bathuthukise. Abasebenzi baqhubeka nokuhamba futhi babhekene nesidingo esikhulayo sokuhlala baxhumeke kumanethiwekhi abo enkampanini.
I-VPN isekela ukude, ukufinyelela okuvikelwe kumahhovisi asekhaya ezinkampani phezu kwe-intanethi. Isixazululo se-VPN se-intanethi isebenzisa iklayenti leklayenti / iseva futhi isebenza kanje:
- Isivakashi esinqunyiwe (iklayenti) enenhloso yokungena kwinethiwekhi yenkampani kuqala ixhumeka kunoma iyiphi inethiwekhi yomphakathi ye-intanethi.
- Okulandelayo, iklayenti iqalisa uxhumano lwe - VPN kwiseva ye-VPN yenkampani. Lokhu kuxhumano kwenziwa ngokusebenzisa uhlelo lwe-VPN olufakwe kwikhompyutha yakude.
- Ngemuva kokuthi ukuxhumeka kusungulwe, iklayenti elikude lingakwazi ukuxhumana nezinhlelo zenkampani yangaphakathi kwi-intanethi njengokungathi zingaphakathi kwenethiwekhi yendawo.
Ngaphambi kwe-VPNs, izisebenzi ezikude zifinyeleleke kumanethiwekhi ezinkampani emigqeni eyimiklomelo eqokiwe noma ngokusebenzisa ama-server wokufinyelela okude. Ngenkathi amaklayenti e-VPN namaseva ngokucophelela adinga ukufakwa kwe-hardware ne-software, i-Internet VPN yisisombululo esikhulu kunazo zonke ezimweni eziningi.
I-VPN yezokuphepha ku-inthanethi yomuntu siqu
Abathengisi abaningana banikeza isevisi yokubhalisa kumanethiwekhi angasese angasese. Uma ubhalisa, uzothola ukufinyelela kwesevisi yabo ye-VPN, ongayisebenzisa kukhompyutha yakho, i-PC noma i-smartphone. Ukuxhumeka kwe-VPN kubhaliwe, okusho ukuthi abantu abasebenzisa inethiwekhi efanayo ye-Wi-Fi (njengokwesitolo sekhofi) abakwazi "ukufiphaza" ithrafikhi yakho futhi banqamule ulwazi olufana ne-akhawunti yakho yomphakathi-media noma imininingwane yasebhange.
Ama-VPN wokusebenza nge-intanethi
Ngaphandle kokusebenzisa amanethiwekhi wangasese angasese ekufinyeleleni okukude, i-VPN ingabuye ibhubhe amanethiwekhi amabili ndawonye. Kule ndlela yokusebenza, inethiwekhi yonke eyikude (kunokuba nje iklayenti elilodwa elikude) ingajoyina kwinethiwekhi yenkampani ehlukile ukuze yenze i-intranet ende. Lesi sxazululo sisebenzisa uxhumano lwe- VPN server- server .
I-Intranet Local Network VPNs
Amanethiwekhi angaphakathi angasebenzisa ubuchwepheshe be-VPN ukuze asebenzise ukufinyelela okulawulwayo okuthunyelwe ngabanye ngaphakathi kwenethiwekhi yangasese. Kule ndlela yokusebenza, amaklayenti e-VPN axhuma kuseva ye-VPN esebenza njengesango lenethiwekhi .
Lolu hlobo lwe-VPN ukusetshenziswa alubandakanyi uMhlinzeki Wesevisi Ye-inthanethi noma iklabhu yenethiwekhi yomphakathi. Noma kunjalo, ivumela izinzuzo zokuphepha ze-VPN ukuba zithunyelwe ngaphakathi kwenhlangano. Le ndlela iye yathandwa kakhulu njengendlela yamabhizinisi ukuvikela amanethiwekhi awo wendawo we-Wi-Fi .
