Ububanzi bokuhlehlisa i-VPN ku-Android: yini eyisusa isendlalelo ngasinye
I-cache, isitoreji sohlelo, ukusetha kabusha inethiwekhi nokusetha kabusha kwefektri kususa izimo ezihlukile ze-Android. Hlanganisa isendlalelo nesimo osola ngaso ngaphambi kokususa iphrofayela.
I-Android inemisebenzi emine ehlukene abantu abayibiza ngokuthi ukuhlehlisa i-VPN, futhi isusa izinto ezahlukene. Ukusula i-cache yohlelo kususa amafayela esikhashana; ukusula isitoreji saso kususa iphrofayela uqobo. Ukusetha kabusha inethiwekhi kwakha kabusha isitaki sokuxhumana, futhi ukusetha kabusha kwefektri kushintsha ingxenye yedatha yomsebenzisi. Khetha umsebenzi ngokwesimo osola ngaso, hhayi ngomkhuba. Uma uqagela kabi, iphrofayela noma indlela yokubhalisa oyidingayo isivele ingekho ngaphambi kokuthi uhlole noma yini.
Nawu umthetho engiwusebenzisa ocingweni ngalunye: shono isimo, shono umnikazi waso, bese ususa ikhophi yalowo mnikazi kuphela. Ingxenye esele yaleli khasi imayelana nokuthi iyiphi ingxenye ye-Android egcina amabhayithi ani.
Iphrofayela ye-VPN ye-Android ihlala kuphi ngempela
Iklayenti lenkampani yangaphandle ocingweni olungaphathwanga ligcina iphrofayela yalo kusikhombisi sayo sedatha yohlelo, njengefayela lezintandokazi, ibhlokhi ye-JSON noma isisekelo sedatha esincane se-SQLite. Yiso leso sikhombisi esisuswa yinto ethi Sula isitoreji kokuthi Izilungiselelo. Iphrofayela ayikho ohlwini lwe-VPN lwesistimu: lolo hlwini lugcina irekhodi lokuxhumana elibhaliswe yiklayenti nge-VpnService, futhi lifaka igama lokuxhumana, iphakethe elingumnikazi nanoma yiliphi ifulegi elihlala livuliwe elisetwe umsebenzisi.
I-VpnService iwumsebenzi wamapayipi, akusona isitoreji. Iklayenti licela imvume kanye, lakha isixhumi esibonakalayo se-tun futhi lihambisa amaphakethe ngokwalo, ngakho ipulatifomu ayidingi neze ukuqonda ifomethi yephrofayela. Yingakho ifayela lokucushwa elikopishwe kwenye ifoni livame ukungeniswa njengephrofayela engenalutho noma lihluleke ukuqinisekiswa.
Imininingwane yokufakazela ubuwena ilandela enye indlela. Ukhiye noma isitifiketi esitholwe nge-KeyChain yesistimu sihlala endaweni yokugcina ephethwe yisistimu, ngakho ukususa idatha yohlelo kungase kushiye imininingwane isebenziseka futhi kususe igama elihlukile leklayenti kuyo kuphela.
Amadivayisi aphethwe angeza umnikazi wesibili. Iphrofayela yomsebenzi edalwe yi-EMM isebenzisa ikhophi yayo yeklayenti ngaphansi kwenqubomgomo yayo, futhi i-VPN ehlala ivuliwe ingananyathiselwa ngenqubomgomo yedivayisi ukuze umsebenzisi angakwazi ukuyixhuma. Kumadivayisi anjalo iphrofayela ivame ukunikezwa ngesikhathi sokubhalisa hhayi ukuthayipha ngesandla. Ngaleso sikhathi ukubuyisela kuyisinqumo sokubhalisa kabusha, hhayi sokungenisa kabusha.
I-cache, isitoreji, ukusetha kabusha inethiwekhi, ukusetha kabusha kwefektri
Imisebenzi emine ihambisana nale mingcele. Funda umugqa wesimo osola ngaso ngaphambi kokuthinta noma yini.
| Operation | What it removes | What survives |
|---|---|---|
| Clear cache | Temporary files, including any diagnostic bundle the client wrote there | Profile, credentials, enrollment |
| Clear storage | The app's preferences, databases and saved profile | KeyChain entries, other apps, device policy |
| Network reset | Wi-Fi, mobile and Bluetooth registrations, and on most builds the saved VPN entries | App data, KeyChain, work profile |
| Factory reset | The user data partition, accounts and device-bound keys | Nothing on the device |
Ukusula i-cache kuphephe kakhulu futhi akusizi kakhulu. Kususa amafayela esikhashana, futhi yilapho iklayenti lingase libeke khona irekhodi elisanda kucelwa yisebenzi yosekelo kuwe. Umhlahlandlela we-Android wokuxazulula izinkinga zohlelo uthatha i-cache nesitoreji njengezinto ezimbili ezihlukene zokususa, futhi nawe kufanele wenze kanjalo.
Sula isitoreji ukusetha kabusha kwangempela kohlelo ngalunye. Kususa iphrofayela, isango eligciniwe namafulegi okuthembana iklayenti eliwagcinile kumathrekhi athile. Akukuhoxisi okufakiwe ku-KeyChain, akususi irekhodi le-VPN lesistimu eliphethwe olunye uhlelo, futhi kwiphrofayela ephethwe akususi inqubomgomo eyaqala ukuthumela iphrofayela.
Ukusetha kabusha inethiwekhi kuzilungiselelo kwenzelwa idivayisi yonke, futhi ubukhulu baso obunembile buyashintsha ngokomkhiqizi nangenguqulo ye-Android. Ibhokisi lokuqinisekisa kukwakho kokwakhiwe yilo kuphela isitatimende esithembekile sokuthi kuzokhohlwa ini.
Qala ngokubhala indlela yokubuya
Ngaphambi kwanoma yisiphi isinyathelo esonakalisayo, bhala izinto ezinhlanu: inguqulo yeklayenti, igama lephrofayela, ikheli lesango, umnikazi wensizakalo kanye nesigaba esiqondile lapho ukuxhumana kwehluleka khona.
Lezo zinto ezinhlanu zihlukanisa iphutha leklayenti ephutheni lenqubomgomo noma leseva. Ukuphela kwesikhathi, ukwenqatshwa kwesitifiketi nokwenqaba ngokushesha kungamaphutha amathathu ahlukene, futhi ngalinye likhomba kumnikazi ohlukile. Uma usula isitoreji kuqala, ulahlekelwa ubufakazi baseceleni kweklayenti obekuzobahlukanisa. Gcina ikhophi ehlanjululwe yerekhodi ngenkathi isekhona.
Bese uqinisekisa ukuthi ukuxhumana kuzokwenziwa kabusha kanjani. Igama lokubonisa negama lomsingathi akwanele lapho iphrofayela yayincike kusitifiketi seklayenti, ekucushweni okuphethwe noma ekubhalisweni kwe-MFA okuboshelwe kule divayisi.
Ukuvalwa kwangaphambili okungekho muntu okuhlelayo
Indlela eyodwa yokwehluleka ifanelwe yisigaba sayo. Uma indawo eyodwa yokulanda iphrofayela iyingosi yangaphakathi efinyeleleka kuphela ngomhubhe ozowususa, ukusula isitoreji kudala indlela evalekile engenakuphuma ngaphakathi kohlelo.
I-VPN ehlala ivuliwe enenketho yokuvimba ukuxhumana ngaphandle kwe-VPN ikwenza kube ukuphazamiseka okuphelele: ifoni ayinayo indlela esebenzayo eya engosini, futhi iklayenti alinayo iphrofayela yokukhuphula umhubhe. Lezi zimo ezimbili zibambana endaweni yazo.
Indlela yokuphuma iwukulandelana kwezinyathelo, hhayi ubuchwepheshe. Khipha noma thatha isithombe sokucushwa ngenkathi umhubhe usasebenza, qinisekisa ukuthi ingosi inomzila onganciki ku-VPN, bese ususa noma yini ngemva kwalokho. Kudivayisi ephethwe, buza umqondisi ukuthi iyiphi indlela yokubuyisela ekhona ngaphambi kokuthinta iphrofayela.
Qinisekisa umhubhe owakhiwe kabusha
Lapho iphrofayela isibuya, hlola ngokulandelana: ukuxazululwa kwamagama, ukuxhumana kwe-TCP nomsingathi wangaphakathi owaziwayo kanye nokuziphatha kokuvimba ukwehluleka okuyikho okuqinisekile okuncike kukho. Ukulandelana kubalulekile ngoba umhubhe ungakhuphuka futhi uvuzise i-DNS.
Isithonjana sokhiye kubha yesimo sifakazela ukuthi isixhumi esibonakalayo sikhona, akukho okunye.
Uma ukuxhumana kusahluleka ngemva kokusetha kabusha okuhlosiwe, yeka ukukhulisa ubukhulu bomsebenzi. Gcina ubufakazi bangaphambi nangemuva, bhala ukuthi yisiphi isendlalelo osisusile, futhi unikeze icala kumnikazi wengxenye kanye nalezo zinto ezinhlanu. Ukusetha kabusha kwefektri yisinqumo esihlukile esinezindleko eziphakeme kakhulu, futhi akusona isinyathelo esilandelayo kuhlu lokuhlola lwe-VPN.
