Ingabe i-VPN ingashesha ukudlula uxhumano oluqondile?

Ukudluliswa okunyonga kuxhumano lwasehhovisi ngezinye izikhathi kuphela ngokushesha kudlula emhubeni, futhi ukufakwa okungeziwe kwenza lokho kubonakale kungenakwenzeka. Le nkathazo ebonakalayo ivela ekuthelekiseni izinto ezingalungile. Umhubo wengeza umsebenzi, futhi ushintsha ukuthi ithrafikhi ihamba ngakuphi ukuxhumana kwenethiwekhi, ikheli elibonwa yindawo okuyiwa kuyo futhi ngezinye izikhathi ukuthi iyiphi iseva ephendulayo. Isinqumo phakathi kwemizila emibili sidinga ukuhlukanisa le mithelela emithathu ngaphambi kwanoma yisiphi isiphetho mayelana nesivinini.

Izinto ezintathu umhubo ongazishintsha

Okokuqala ukudlula. Ukuhlelwa komzila kwe-inthanethi kulandela inqubomgomo yomhlinzeki kanye nobudlelwano bezebhizinisi, hhayi ukubambezeleka okukaliwe, ngakho umzila odlula kumhlinzeki we-VPN ungadlula kwezinye izinethiwekhi kunomzila oqondile. Kungagwema indawo yokushintshana egcwele noma kwehle endaweni ene-peering engcono, futhi kungaba kubi ngokulula okufanayo.

Okwesibili indawo okuyiwa kuyo. Ukushintsha kwekheli lokuphuma kuvame ukushintsha impendulo ye-DNS, futhi inethiwekhi yokuqukethwe ingakunikeza enye ikheshi noma esinye isifunda. Ngakho ingxenye yokuthuthuka ingeyaseva entsha hhayi eyomhubo. Igama elifanayo lomsingathi lingehla kuseva eseduze noma engasindwanga kangako ngaphandle kokuthi kushintshe lutho kuklayenti.

Okwesithathu ukuziphatha kokuthutha. Ukufakwa kushintsha usayizi wephakethe osebenzayo, futhi umhubo ogwema ingxenye ephakathi enokulahleka ungavumela ukugeleza kwe-TCP ukuthi kukhulise iwindi lakho esikhundleni sokuphinda kuhlehle. Akukho kokukodwa kwalokhu okuwumshini wokusheshisa jikelele; ngakunye kuyisimo okufanele kuqashelwe. Ukuhlukanisa kwabo yikho okuguqula ilukuluku kube iqiniso.

Lokho okungeke kukushintshe

Akukho lutho emhubeni olwengeza umthamo kuxhumano phakathi kwedivayisi nenethiwekhi. Isiteshi se-Wi-Fi esigcwele, imayela lokugcina eligcwele noma uhlelo lweselula olunomkhawulo kukhawulela imizila yomibili ngokufanayo, futhi ukuhlolwa kwesivinini ngomhubo akukwazi ukweqa lowo mkhawulo. Ukuxhumana okufanayo kuthwala amaphakethe afakwe, ngakho ukufakwa kungasebenzisa umthamo kodwa akukwazi ukuwudala. Okushintshayo ukuthi amaphakethe aya kuphi ngemuva kokushiya lokho kuxhumana. Yikho ukuthi umphumela womhubo osheshayo uhlala unencazelo engaphezulu kokugxuma kokuqala.

Imingcele ohlangothini lweseva nayo ayinaki. Uma umsingathi okude ukhonza kancane, umzila ongcono uletha impendulo enensayo ngempumelelo ephezulu kuphela, futhi umsebenzisi usalindile. Umthombo owabiwe ngaphansi komthwalo ubonakala unensayo kuyo yomibili imizila ngasikhathi sinye.

Qhathanisa imizila ngendlela efanele

Gcina uhlelo lokusebenza, indlela, ubude besikhathi kanye nokwenzeka ngasikhathi sinye kufana, futhi shintsha umzila kuphela. Gijimisa ukuhlolwa ngakunye ngaphezu kokukodwa, ngesikhathi esifanayo sosuku, futhi bhala ikheli lokuphuma kanye nempendulo yesixazululi eceleni kokudluliswa kwedatha. Ukugijima kanye kuyisampula hhayi isilinganiso, futhi ukulandwa okukodwa okusheshayo kungaba ukushaya kwekheshi okungasho lutho ngomzila. Bhala imibandela ngaphambi kwemiphumela, ngoba izinombolo zinzima ukuzichaza kamuva.

Impendulo yesixazululi yimininingwane eminingi yokuqhathanisa eyeka, futhi ichaza “intuthuko” enyamalalayo lapho iseva efanayo iphoqelelwa. Uma ikheli lihluka phakathi kokugijima, ukuhlolwa kuqhathanise izindawo ezimbili hhayi imizila emibili. Bika ukubambezeleka nokulahleka eceleni kokudluliswa kwedatha, ngoba umzila osheshayo kukonke kodwa owengeza ukubambezeleka kusizo ngalunye lokucela akulungile emthwalweni womsebenzi owakhononda. Isikhathi sokuhamba nokubuya sibaluleke kakhulu kunesivinini esikhulu kunoma yini ebuza futhi ilinde.

Nini umehluko ofanele ukugcinwa

Uma umhubo ogunyaziwe uthuthukisa ngokuthembekile umthwalo othile womsebenzi, lokho kuyisinqumo esisemthethweni sokusebenza: bhala umthwalo womsebenzi, isilinganiso kanye nokuphuma okusetshenzisiwe. Irekhodi elisebenzayo lisho umsingathi oyedwa, ikheli lokuphuma elikhiqizwe umhubo, impendulo yesixazululi kanye nezinombolo ezifanayo ezivela emzileni oqondile ngosuku olufanayo. Lokho kwanele ukuthi unjiniyela olandelayo aphinde ukuqhathanisa esikhundleni sokuphikisana futhi. Akukabi ubufakazi bokuthi umhlinzeki ukhawulela okuthile, futhi akudluliselwa kwezinye izinhlelo noma amanye amahora.

Gcina irekhodi lesilinganiso kanye nokucushwa. Liphendula umbuzo olandelayo wokuthi intuthuko isekhona yini, futhi yiyo kuphela indlela yokwazi ukuthi umzila noma umthwalo womsebenzi ushintshile. Irekhodi elingenalo usuku alikwazi ukuphendula lowo mbuzo nhlobo.
