Ingabe i-VPN noma i-proxy ingakopisha okuqukethwe okunelungelo lobunikazi? Izenzo ezintathu

Ukudluliswa kwamaphakethe, ukugcinwa kwezimpendulo kunye nokushicilelwa kabusha kubonakala kufana kudashibhodi kodwa kuziphatha ngendlela ehluke ngokuphelele uma umbuzo welungelo uvela. Isevisi ehambisa amabhayithi phakathi komsebenzisi neseva yenza isenzo esisodwa, kuyilapho eyagcina impendulo futhi iyinikeza isivakashi esilandelayo yenza esinye. Ukushicilela okokunye ngaphansi kwegama lakho yisenzo sesithathu, futhi yisona kuphela isenzo sesithathu esiyukusabalalisa ngomqondo ojwayelekile.

Thola ukuthi imuphi kulezi zintathu umhlu wakho owenze ngempela, bese uhlanganisa umthetho ohambisana nawo. Amalebula omkhiqizo awanqumi lutho lapha, futhi iphrothokholi esetshenziswayo nayo ayisona isilinganiso.

Izenzo ezintathu i-proxy noma i-VPN engazenza

Igeyithiweyolo lamukela ukugeleza kwe-TCP, libhala kabusha amakheli futhi lidlulise izingxenye kuzo zombili izinhlangothi. Akukho okusala kudiski ngemva kokuxhumana, futhi umthwalo uhlala ungacacile kugeyithiweyolo ngaphandle uma iklayenti lixoxa nge-TLS negeyithiweyolo esikhundleni somthombo.

Ummeli ogcina kucashu usebenza ngendlela ehlukile: uhlaziya isicelo, ugcina impendulo isikhathi sokuphila esikubalayo noma esikufunda kumakhanda, bese ephinda adlale leyonto egciniwe kumaklayenti akamuva. Manje kukhona okuthile ngaphandle kocingo, okubhalwe nge-URL nesiqinisekisi, futhi ukugcinwa kwayo kuwukukhetha kokuhlelwa hhayi umphumela oseceleni.

Ukushicilelwa kabusha kuhamba isinyathelo esisodwa phambili. Okokugcina kusengxenyeni yengqalasizinda oyilawulayo, kubhekiswe kubabukeli obakhethile, ngokuvamile ngemva kokuhlelwa. Izenzo ezimbili zokuqala zichaza ukuthutha, esesithathu sichaza ukusabalalisa.

Lapho i-proxy ehlukanisa ukubhala iguqula ukuthutha kube ukukopisha

Umehluko onquma izimpikiswano eziningi ukuthi ingabe ibhokisi lake lalibamba umbhalo ocacile. Ithubhu elihlanzekile, kungaba i-WireGuard, idivayisi ye-OpenVPN tun noma ukudluliswa kwe-SSH -L, ihambisa umbhalo obethelwe phakathi kweziphetho futhi ayishiye lutho olufundekayo. I-proxy eqeda i-TLS yenza okuphambene: iqeda ukuxhawulana, igcina impendulo ememorini, bese ibethela kabusha ukugeleza ibheke kuklayenti. Phakathi kwaleyo misebenzi umsebenzi ukhona ngendlela umqhubi angayihlola futhi ayigcine.

17 USC 106 kubala ukukhiqizwa kabusha nokusabalaliswa phakathi kwamalungelo akhethekile, futhi ngayinye ingaphansi kwemikhawulo ebekwe kuyo leyo khodi. Ibhafa lemiliyisekondi lingangena emkhawulweni ngaphandle kwengxabano; into egciniwe futhi edlaleka kabusha inzima kakhulu ukuyibeka lapho. Ubude nenhloso zinesisindo esikhulu kunokuthi imemori yathintwa.

Akukho kulokhu okwenza i-VPN ibe yilayisense, futhi akukho okwenza wonke ama-proxy abe ngabaphuli. Ukuthutha kuyiqiniso elilodwa phakathi kwamanye, futhi umbuzo ongahlolwa uhlala unjalo: isiphi isenzo, kokabani, ngaphansi kwaluphi ugunyazo.

Amakhanda kucashu achaza ugunyazo lwephrothokholi, hhayi ugunyazo lwezomthetho

Icashu ye-HTTP inquma ukuthi ingagcina ini kusukela kumethadatha yempendulo, futhi i-RFC 9111 ibeka imithetho eyilandelayo. Cache-Control: no-store itshela wonke amacashu ahambisanayo ukuthi alahle impendulo, kuyilapho private ikhawulela ukusetshenziswa kabusha kumsebenzisi oyedwa futhi max-age ende imema ukugcinwa okwabiwe. Isicelo esisodwa sikutshela ukuthi umthombo ukhethe yiphi inqubomgomo. Yisebenzise ngaphambi kokuxoxa nganoma yini enye.

Impendulo ekhangisa ukuphila isikhathi eside itshela amacashu ukuthi ukudlalwa kabusha kwamukelekile ezingeni lephrothokholi. Leyo statement ayisho lutho mayelana nokuthi ungayithatha yini leyo nto, uyibambe kabusha futhi uyifake kusevisi yakho. Izigunyazo ezimbili ezahlukene zivela emishinini emibili ehlukene, futhi ukwanelisa okukodwa kushiya okunye kuleyondawo eyayikuyo.

Icala lesibuko lehluleka ngendlela efanayo. I-HTTPS yokuphela kuya ekupheleni ivimbela icashu esobala ukuthi igcine noma yini, kodwa lowo mphumela awudali ilungelo lokusabalalisa okokugcina futhi awususi elalivele unalo. Ukuziphatha kwephrothokholi kuchaza ukuthi ibhokisi lingenzani; akuniki gunyazo.

Yini okufanele ibhalwe phansi ngaphambi kokuthi isevisi iqale

Chaza ukuhlelwa ngamagama umuntu wangaphandle angakwazi ukuwaqinisekisa. Biza okokugcina nomthombo wakho, bhala izenzo ezenziwa uhlelo, futhi usho ukuthi into ngayinye egciniwe iphila isikhathi esingakanani.

Gcina leyondeskripthini kanye nokuthunyelwa hhayi ememorini yomuntu. Uma kufika isikhalazo, igebe phakathi kwesimo esivikelekayo nokuqagela ngokuvamile iyisigaba esabhalwa ezinyangeni ezedlule esibiza isikhathi sokugcina nelayisense.

Uhlu olufushane lokubuyekeza luhlanganisa izimbobo eziphindayo:

• Umthombo wokokugcina kanye nemibandela enamathiselwe kuyo.
• Isenzo ngasinye esenziwe: ukudlulisa, ukugcina, ukuhlela, ukunikeza.
• Ukugcinwa ngekilasi ngalinye lento, ngamahora noma ngezinsuku.
• Ugunyazo noma umkhawulo okusekelwe kuwo isinyathelo sokunikeza.
• Ukuxhumana nendlela yokususa yabanikazi bamalungelo.

Sebenzisa uhlu ngokuhlelwa okusebenzayo, hhayi ngomdwebo wokwakhiwa. Lapho impendulo ingekho, lelo gebe ngumsebenzi olandelayo: noma thola ugunyazo lwesenzo noma yeka ukusenza. Ngesevisi yezentengiselwano, yenza ummeli afunde indeskripthini ebhaliwe uma iqhathaniswa nendawo yomthetho osebenza kuyo, ngoba indeskripthini iyona eyenza lokho kubuyekeza kwenzeke. Noma yini ongeke uyichaze ngokubhala yisimo ongeke ukwazi ukusivikela.
