I-DNS phezu kwe-TLS kanye ne-VPN: iyiphi ingxenye evikelwe

I-DNS phezu kwe-TLS ibethela ukushintshana phakathi kwekhasimende ne-resolver ekhethile, futhi i-resolver isafunda igama. Lowo musho uxazulula iningi lokudideka mayelana ne-DoT kanye ne-VPN. Umhubhe unquma ukuthi umbuzo obethelwe uhamba ngamuphi umzila, kuyilapho i-resolver isafunda ukuthi kwabuzwa ukuthi ini. Akukho ndlela eyodwa ethatha indawo yenye, futhi akukho okwenza enye ibe ngokweqile.

Izivivinyo ezine zinquma ukuthi ukuhlelwa onakho yikho yini ocabanga ukuthi unakho.

Isivivinyo 1: ukubethela kumboza ini

I-DoT isonga ukushintshana kwe-DNS ku-TLS, ngakho umbonisi osendleleni ubona ukuxhumana okuya kukhelile nechweba esikhundleni segama elisembuzweni. I-resolver ngokwayo iyavula ukubethela futhi iphendule. Qhathanisa ne-DNS phezu kwe-HTTPS: zombili ziyabethela, futhi zisebenzisa izindlela zokuthutha ezihlukene, ngakho inethiwekhi evumela ithrafikhi yewebhu ayivumeli ngokuzenzakalelayo ukuxhumana kwe-DoT.

Lowo mehluko ubalulekile lapho ingosi yokubamba noma ibhokisi eliphakathi elihlungayo livumela u-443 futhi livimba u-853. Ithuluzi elasebenza lapho akusona ubufakazi bokuthi elinye lizosebenza.

Isivivinyo 2: umbuzo uthatha umzila upi

Umzila uyindaba yenqubomgomo yekhasimende. I-resolver ye-DoT ingafinyelelwa ngomhubhe, ngaphandle kwawo, noma ngomzila oshintsha nenethiwekhi. Ukuphi okuzokwenzeka kuncike emizileni nasekutheni ukuthi ikhasimende livikela isokhethi yalo ye-DNS. Umhubhe obamba yonke ithrafikhi ngokuvamile uthatha umbuzo nawo, kungakhathaliseki ukuthi ikheli le-resolver lithini.

Ukubona ikheli le-resolver yomunye umuntu esivivinyweni akubonisi ukugwema, futhi ukubona ukubethela akubonisi umamukeli ohlosiwe. Funda i-resolver nomzila ngokwehlukana, bese unquma ukuthi leli khosi yilo oyihlele.

Isivivinyo 3: amagama angaphakathi

Inhlangano eshicilela amagama angaphakathi idinga i-resolver egcina lawo marekhodi. Isevisi ye-DoT yomphakathi ayilwazi igama lakho langasese, futhi ukuqondisa ikhasimende kuyo kuqinisekisa ukuthi lawo magama azohluleka. Lokhu kuwukuhlehla okungokoqobo okuvame kakhulu lapho umuntu evula i-DNS ebethelwe kudivayisi elawulwayo.

Gcina i-resolver yangaphakathi yezijobelelo zangaphakathi futhi ubethela lowo gxuma uma inqubomgomo ikudinga, esikhundleni sokuyishintsha ngomhlinzeki womphakathi.

Isivivinyo 4: ukuziphatha lapho kuhluleka

Isilungiselelo esiqinile se-resolver ngaphandle kwe-resolver efinyelelekayo sidala ukuhluleka kokuxazululwa kwegama ngenkathi umhubhe umi. Bheka imodi yeplatifomu kanye nokubuyela emuva kwayo okubhaliwe esikhundleni sokuthinta okhiye noma izitifiketi.

Ukubuyela emuva okusebenzisa i-DNS evamile buthule kuyisinqumo senqubomgomo, hhayi ukunethezeka. Nquma ukuthi ukuhluleka kufanele kubonakale noma kufanele kwehle kuye kokuthile okubuthakathaka, futhi ubhale impendulo.

Themba isitifiketi, hhayi impendulo

Sebenzisa igama lomsingathi lomhlinzeki kanye nokuhlelwa kokuqinisekisa okubhaliwe kwesevisi. Ukucisha izivivinyo ze-TLS ukuze i-resolver engaziwe iphendule kukunikeza isiteshi esibethelwe esiya endaweni yokugcina engaqinisekisiwe, okubi kakhulu kunombuzo ovamile eyawuthatha indawo ngendlela eyodwa ethile: kubonakala kuphephile. Isicaciso se-DNS over TLS siveza ukulindelwa kokuqinisekisa okungemuva kwalokho kuhlola.

Impendulo evela ku-resolver ongakwazi ukuyiqinisekisa iyisimangalo, hhayi umphumela.

Lokhu kushiya ini kungachazwanga

I-DoT ayifihli igama ku-resolver, ayifihli ikheli lendawo okuya kuyo yokuxhumana kunethiwekhi, futhi ayinqumi ukuthi umbuzo udlule emhubheni. Leyo yimibuzo emithathu ehlukene kanye nezimpendulo ezintathu ezihlukene.

Bhala ubunjalo be-resolver, umzila wokudlula kanye nenqubomgomo yamagama angaphakathi njengemigqa emithathu. Umbuzo we-DNS olandelayo ozowuthola uzoba ngenye yazo.
