Kungani i-VPN yakho ithatha isikhathi eside ukululama kunokuphazamiseka

I-Wi-Fi ibuye emasekhondini angamashumi amathathu edlule kanti i-VPN isavalekile, ngakho iklayenti libonakala liphukile. Ngokuvamile lilandela uhlelo lwalo lokuzama kabusha, futhi lolo hlelo alwazi ukuthi inethiwekhi isanda kubuya. Leyo gebe yiyona ndaba yonke: isikhathi sokululama siwukuphazamiseka kanye nanoma yikuphi ukulinda iklayenti elikuvumile kakade. Ukwehlisa zonke izikhathi kuyimpendulo eyodwa, futhi ukuqonda ukuthi iyiphi isikhathi ebalulekile kungenye.

Izimo ezintathu zinquma ukuthi ukulungisa kuyasiza yini: isiphi isigaba esiphuzayo, ukuthi ukwehluleka kungaphindwa yini, nokuthi iklayenti lalifunda kanjani ukuthi inethiwekhi ibuyile.

Ukulinda okuthathu okubonakala kukodwa

Ukuxazululwa kwephoyinti lokugcina, ukuxoxisana kwe-IKE noma i-TLS, ukuthumela kabusha kwamaphakethe kanye nokuqala umzamo omusha yizigameko ezihlukene ezinezikhathi ezihlukene. I-strongSwan ibhala ukuhlehla kokuthumela kabusha kwe-IKE, kanti i-OpenVPN inezilawuli zayo zokuzama kabusha ezinencazelo ehlukile. Ukukopisha inombolo kusuka kwelinye kuya kwelinye kucabanga ukuthi izindlela ziyafana, kodwa azifani. Funda ukulandelana kwelogi ngaphambi kokunquma ukuthi ubheka isikhala sini.

Umzuzu othule kulogi awusho ukuthi inqubo ibhajwe. Kungase kube ukuhlehla okukhulayo okwenza impela lokho okwakulungiselelwe.

Isiphi isigaba esiphuzayo ngempela?

Uma ilogi ibonisa imizamo ehluleka ngephutha lokufakazela ubuqiniso, akukho ukushintsha kwesikhathi okusizayo, ngoba imininingwane yokungena ayilungile. Uma kungekho mizamo eyenziwayo nhlobo, iklayenti lingaphakathi kwefasitela lalo lokulinda futhi uhlelo luyisixazululo. Uma imizamo yenziwa futhi iphelelwa yisikhathi, inkinga ukutholakala noma umlaleli ongekho, futhi ukuzama kabusha ngokushesha kugcwalisa ilogi kuphela. Ngayinye yalezo zimo ezintathu inomnikazi ohlukile, futhi eyodwa kuphela yazo inkinga yesikhathi.

Hlukanisa ukwehluleka ngaphambi kokuthinta inombolo.

Nini ukwehlisa isikhathi kusiza, futhi nini kungasizi

Yehlisa umkhawulo wokuzama kabusha lapho izindleko ezinkulu kuwukulinda ngemva kokuphazamiseka okufushane nokuvamile, njengekhompyutha ephathekayo ehamba phakathi kwamaphoyinti wokufinyelela.

Kuzo zombili izimo, shintsha ipharamitha eyodwa, yirekhode, futhi linganisa ukululama okulandelayo esikhundleni sokucabanga ukuthi kube ngcono.

Isikhathi sokuphelelwa esiphansi kakhulu esikopishwe kuwo wonke amaphrofayili siyisimo sokugcina esivamile sokulungisa ngaphandle kokulinganisa.

Hlola ukulungela ngaphambi kokusola iklayenti

Iklayenti ngokuvamile alikwazi ukubona ukuthi inethiwekhi iyasebenziseka kuze kube yilapho okuthile kuzama. Iphothali eboshiwe, ukuvuselelwa kwe-DHCP noma ukushintsha komzila kungase kulishiye lilinde uhlelo olwabekwa ngaphambi kokuba konke lokho kwenzeke. Bheka ukushintsha kwesimo senethiwekhi kwesistimu yokusebenza nomzamo olandelayo weklayenti kuwashi elilodwa, futhi uzobona ukuthi ukulinda kukabani. Indlela esheshayo iwukubhala uphawu lwesikhathi somcimbi wenethiwekhi-esilungele nophawu lwesikhathi somzamo wokuqala ngemva kwawo.

Qinisekisa futhi ukuthi ithrafikhi eqondile isavinjiwe ngesikhathi sokulinda, ngoba ukuxhuma kabusha okusheshayo okuvuza ithrafikhi akusona ukuthuthuka.

Yini okufanele irekhodwe

Bhala ukuthi yisiphi isikhathi esishintshile, kusuka kweliphi inani kuya kweliphi, nokuthi ukululama kwakunjani ngemva kwalokho. Bhala futhi inguqulo yeklayenti, ngoba izindinganiso ziyashintsha phakathi kwezinguqulo futhi isikhathi sokuphelelwa esiphansi kakhulu esingabhalwanga sizodida umuntu olandelayo ofunda iphrofayili.

Lokho kurekhoda kuguqula ukuthuthukiswa kwesoftware okulandelayo kube ukuqhathanisa esikhundleni sokuhlola.
