Uuesimas v\u00e4rskenduses GrapheneOS kaitstud mobiilplatvormil 2024053100 lisandus seadme andmete h\u00e4daolukorra lukustamise funktsioon. Kasutajale antakse v\u00f5imalus seada lisapass ja PIN-kood, mille sisestamine kustutab k\u00f5ik v\u00f5tmed riistvarasalvedes, sealhulgas v\u00f5tmed, mida kasutatakse andmete kr\u00fcpteerimiseks salvestis, samuti kustutab eSIM-i ja taask\u00e4ivitab seadme. Seega, kui kasutajale avaldatakse survet seadme ekraani avamiseks v\u00f5i kui on oht, et nutitelefon satub valedesse k\u00e4tesse, saab seadme omanik sisestada destruktiivse PIN-koodi ja lukustada andmed ilma juurdep\u00e4\u00e4su taastamise v\u00f5imaluseta. <\/p>\n

GrapheneOS projekt arendab Androidi (AOSP, Android Open Source Project) koodibaasi haru, mis on laiendatud ja muudetud, et suurendada turvalisust ja tagada privaatsus. Enamik praeguseid Google Pixel seadmeid (Pixel 4\/5\/6\/7\/8, Pixel Fold, Pixel Tablet) on ametlikult toetatud. Projekti arendused on avaldatud MIT litsentsi all. See h\u00f5lmab mitmeid katsetehnoloogiaid, mis on seotud rakenduste isoleerimise tugevdamise, juurdep\u00e4\u00e4su detailse juhtimise, t\u00fc\u00fcpvigade ilmingute blokeerimise ja eksploitide toimimise keerukuse suurenemisega. <\/p>\n

N\u00e4iteks platvormil kasutatakse oma malloc rakendust ja muudetud libc varianti, mis kaitseb m\u00e4lu kahjustumise eest, ning rangemat protsesside aadressiruumi jagamist. Androidi runtime'is kasutatakse ainult ettevarendavat (AOT, ahead-of-time) kompileerimist JIT asemel. Linuxi tuumas on lisatud palju t\u00e4iendavaid kaitsemehhanisme, n\u00e4iteks slubis lisatakse kanarikkad sildid puhver\u00fcletamiste blokeerimiseks. Rakenduste isoleerimise tugevdamiseks on kaasatud SELinux ja seccomp-bpf. <\/p>\n

On the operating system, selective access can be granted to specific applications for network operations, sensors, the address book, and peripheral devices (USB, camera). By default, access to information such as the IMEI, MAC address, SIM card serial number, and other hardware identifiers is prohibited. Reading from the clipboard is only allowed for applications currently in focus. Additional measures are included to isolate processes related to Wi-Fi and Bluetooth and to prevent leaks due to wireless activity. Many of the security enhancement mechanisms developed within the project have been integrated into the main Android codebase. <\/p>\n

GrapheneOS employs cryptographic verification of uploaded components and advanced data encryption<\/a> failis\u00fcsteemide tasemel ext4 ja f2fs (andmed kr\u00fcpteeritakse AES-256-XTS abil ning failinimed - AES-256-CTS kasutades HKDF-SHA512, et genereerida iga faili jaoks eraldi v\u00f5ti), mitte plokiautomaadi tasemel. S\u00fcsteemipartitsioonide ja iga kasutajaprofiili andmeid kr\u00fcpteeritakse erinevate v\u00f5titena. Kasutatakse olemasolevaid riistvarav\u00f5imalusi, et kiirendada kr\u00fcptimisoperatsioone. Lukustuskuval kuvatakse sessiooni l\u00f5petamise nupp, millele vajutades l\u00e4htestatakse dekodeerimisv\u00f5tmed ja salvestus muudab staatust mitteaktiveerituks. On olemas seadistus, mis keelab t\u00e4iendavate rakenduste installimise valitud kasutajaprofiilides. Paroolir\u00fcnnete eest kaitsmiseks on kasutusele v\u00f5etud viivitus s\u00fcsteem, mis s\u00f5ltub eba\u00f5nnestunud katsete arvust (30 sekundist kuni 1 p\u00e4evani). <\/p>\n

GrapheneOS ei sisalda p\u00f5him\u00f5tteliselt Google'i rakendusi ja teenuseid ning ka Google'i teenuste alternatiivseid rakendusi, nagu microG. Samuti on v\u00f5imalus installida Google Play teenuseid eraldi isoleeritud keskkonnas, millel puuduvad erilised \u00f5igused. Projekt arendab ka mitmeid oma rakendusi, mille fookuses on teabe kaitsmine ja privaatsus. Eelk\u00f5ige pakutakse Chromiumi baasil t\u00f6\u00f6tavat veebibrauserit Vanadium, muudetud varianti WebView mootrist, turvalist PDF-vaaturit, tulem\u00fc\u00fcri, Auditor rakendust seadmete kontrollimiseks ja sissetungide tuvastamiseks, kaamerarakendust, mis keskendub konfidentsiaalsuse tagamisele, ja kr\u00fcpteeritud varukoopiate loomise s\u00fcsteemi Seedvault.
