Ingabe ilogi ye-VPN ingakhombisa umlando wokuphequlula? Yini ubufakazi obuyikhombisayo
Ilogi yesikhathi, umbuzo wesixazululi kanye nerekhodi lokugeleza kufakazela izinto ezihlukene. Khetha umbuzo, hlanganisa ubunikazi nesikhathi, bese usho kuphela lokho okukhonjisiwe.
Imibuzo emibili yokucwaninga izwakala ifana kodwa idinga ubufakazi bezinhlobo ezahlukene. Ukuthi iyiphi isikhathi esixhumene naleli kheli kungaphendulwa kusuka kumarekhodi okuxhumana nawokugeleza. Ukuthi imuphi umuntu uvule leli khasi ngokuvamile akukwazeki, okungenani hhayi kusuka kuleyo marekhodi. Ukukhetha umqoqi ngaphambi kokukhetha umbuzo yiyo indlela iqembu lenethiwekhi eligcina ngokwethula igama lomsingathi njengomlando wokuphequlula.
Qala ngommcimbi okufanele ukucwaninga kuwuqinisekise
Bhala umbuzo njengomusho onomhlangano, isenzo nesikhathi. Ukuziphatha lokho kuphela kuveza igebe phakathi kwerekhodi lesikhathi nokubukwa kwekhasi. Ilogi yesikhathi iqinisekisa ukuthi ubunikazi bamukelwe, isikhathi esithile, nekheli elinikezwe ngaphansi kwenqubomgomo erekhodiwe, futhi ayikwazi ukuqinisekisa ukuthi ubani ufunde liphi ikhasi ngoba ayikaze iyibone isicelo.
Beka ilebula ekuboneni ngaphambi kokudizayina ukuqoqwa. Inkambu eqanjwe ngesizindalwazi esivakashelwe kodwa eqinisweni igcina igama elixazululiwe iyiphutha lesikhathi esizayo, hhayi ukunethezeka. Amagama ezinkambu aphila isikhathi eside kunabantu abawakhethile, ngakho khetha lawo achaza ubufakazi hhayi isiphetho.
Irekhodi ngalinye lingasekela ini futhi lingakwazi ukusekela ini
Izinhlobo ezine zamarekhodi zivela cishe kukho konke ukudizayinwa kokucwaninga, futhi ngayinye iphendula umbuzo ohlukile. Zigcine zehlukene kumbiko nakumzila, ngoba ukuzihlanganisa yiyo indlela okutholakele okuvikelekayo okuba yihlazo ngayo.
| The question being asked | Record that can answer it | What that record proves | What still needs a join |

Funda ikholomu yokugcina ngokuqaphela okufana neyaphakathi. Irekhodi lokugeleza lichaza amakheli namachweba, futhi ukusesha okuhlanekezelwe kwekheli akukhiqizi kabusha igama elisetshenziswe isiphequluli, ngoba ikheli elilodwa lingasingatha izizindalwazi eziningi ezingahlobene. Umbuzo wesixazululi ufakazela ukuthi umbuzo ubuthelwe, hhayi ukuthi ikhasi likhonjisiwe. Igama lomsingathi elibonakala ngesikhathi senkulumo ye-TLS nalo aliyona indlela yesicelo esibethelwe.
Ngakunye kwalokhu ukubona kwangempela, futhi akukho lokhu okuwukubona abantu abakucabangayo. Isiphequluli esiphikelela kusixazululi saso esibethelwe siphuma ngaphandle kobubanzi obuqashwe, futhi ukuhlaziya akukwazi ukubuyisa lokho ukuloga okungakaze kubone. Lelo gebhe kufanele libe embikweni njengomkhawulo oshiwo, hhayi umbhalo waphansi.
Ukusesha okuqagelayo nezimpendulo ezivela kusilondolozo
Iziphequluli zixazulula amagama kusengaphambili, ngezinye izikhathi ngaphandle kokulayisha lutho. Ziphendula futhi zisuka kusilondolozo ngaphandle kokuthumela umbuzo omusha kusixazululi osigadile, okusho ukuthi ukungabikho kombuzo akukona ukungabikho kokuvakasha. Kokubili lokhu kuziphatha kuphula isibalo esilula phakathi kwelogi ye-DNS nomlando wokuphequlula.
I-DNS over HTTPS yengeza umngcele wesibili: isiphequluli noma uhlelo lwesivakashi olunesixazululi salo alikaze libuze lutho kumlogi wenhlangano. Ukuthengiselana okuqondile kuvela kuphela ezenzakalweni zohlelo ngokwalo noma kummeleli ogcinwe nguye ukuloga kwakhe okusekelwa ngokusobala. Umhubhe ojwayelekile we-HTTPS CONNECT awuniki ummeleli umbono wezindlela zamakhasi ngaphakathi. Ukuba ngumnikazi wenethiwekhi akusona isigunyaziwe sokushintsha buthule imodeli yokuthembela yohlelo.
Ikheli lingelesikhathi, hhayi elomuntu
Irekhodi lokugeleza eliphethe ikheli lobubanzi bomhubhe liyisiqalo, hhayi impendulo. Hlanganisa lelo kheli nesigxivizo sesikhathi nokwabiwa kwesikhathi obekusebenza ngaleso sikhathi, ngoba ikheli lingabelwa esinye isikhathi ngemva kwehora. Ukwabiwa kwamakheli okungaguquki kuyindlela eyodwa yokugcina lobo buxhumano, hhayi ukuphela kwezindlela.
Lapho isinyathelo sokuhumusha sihlanganisa amadivayisi amaningi abe ikheli lomthombo elilodwa ngaphezulu kwesinzwa, ukuhlanganisa kungasho kuphela isikhathi segethiweyi esabiwe. I-akhawunti eyabiwe noma isitifiketi esisetshenziswa abantu abaningi kunciphisa ukwabiwa kwayo noma nini idatha yenethiwekhi ibonakala iphelele kangakanani. Kokubili kufanele kube embikweni njengemikhawulo, hhayi izixwayiso zangemva.
Rekhoda isifunda sesikhathi, umthombo wewashi, iphuzu lokubona kanye nayo yonke imingcele yokuhumusha phakathi kwazo. Ukungabikho kufanele kunakwe njengokuba khona, ngoba irekhodi elilahlekile lingasho ukuthi ingeno yokugeleza iphelelwe yisikhathi, isinzwa asikaze sibone iphakethe noma ilogi yohlelo ibivaliwe.
Dizayina ngenhloso eshiwo, bese ufakazela umzila
Uma umbuzo usumisiwe, chaza ukuthi yiziphi izinkambu ezidingekayo, ubani angazifunda, futhi zigcinwa isikhathi esingakanani. Ukuqoqa okwengeziwe ngoba indawo yokugcina ishibhile kwakha umthwalo ohlala isikhathi eside kunophenyo. Imodeli yobumfihlo ku-RFC 6973 ibheka ukuhlobana, ukwabiwa okungalungile nokuqoqwa okungadingekile njengezinkinga zokudizayina, hhayi umcabango wangemva.
Vikela ukuhla namarekhodi njengento eyodwa, ngoba ngakunye kukodwa akubucayi kangako kunombhangqwana. Bese uqinisekisa ukudizayinwa ngokusebenza okuvunyelwe ukukhiqiza nokose ukukuqonda kakade, usebenzisa umbuzo omncane kakhulu umbiko ozoncika kuwo. Umzila ongakwazi ukuphinda ukhiqize umcimbi owaziwayo nawo ngeke uphinde ukhiqize ongaziwa. Bika umcimbi osekelwa ubufakazi, ngamagama avunyelwe ubufakazi, bese uyeka umfundi afinyelele isiphetho esikhulu ngokwakhe.
Bhala imikhawulo eceleni kokutholakele: yini ehlanganisiwe, yini ehumushiwe, futhi iyiphi ilogi ethule. Ukutholakele okusho imingcele yako kuhlala ekubuyekezweni okungeke kuhlale kukho isifinyezo esizethembayo. Lowo umehluko phakathi kobufakazi nendaba emayelana nobufakazi.
