Jasper Nuyens, grunnleggeren av Linux Belgium, som utviklet et lag for bruk av Linux i informasjonssystemet til Tesla-biler, foreslo en enkel metode for \u00e5 redusere angrepsflater p\u00e5 Linux-kjernen for \u00e5 senke sannsynligheten for kompromittering i lys av en \u00f8kning i oppdagelsen av farlige s\u00e5rbarheter ved hjelp av AI. Siden mange s\u00e5rbarheter vanligvis finnes i spesifikke kjernemoduler som er tilgjengelige for automatisk lasting, men som vanligvis ikke brukes av de fleste brukere, foreslo Jasper \u00e5 som standard blokkere moduler som ikke er i bruk i det aktuelle systemet eller generelt sjelden brukes. <\/p>\n

Kjernen har flere tusen moduler tilgjengelig, men i de fleste systemer brukes bare noen hundre, mens resten forblir tilgjengelige for lasting og potensielt kan inneholde s\u00e5rbarheter. Ideen er implementert gjennom skriptet ModuleJail, som definerer listen over moduler som brukes i det aktuelle systemet (gjennom \/proc\/modules) og automatisk setter ubrukte moduler p\u00e5 svartelisten. Skriptet er skrevet i shell, bruker vanlige systemverkt\u00f8y (bare busybox er n\u00f8dvendig) og distribueres under GPLv3-lisensen. <\/p>\n

Skriptet st\u00f8tter kj\u00f8ring p\u00e5 Debian, Ubuntu, RHEL, Fedora, SUSE, AlmaLinux, Rocky Linux, Alpine og Arch Linux, og som et resultat av sitt arbeid genererer det filen \/etc\/modprobe.d\/modulejail-blacklist.conf, som brukes av systemet for \u00e5 deaktivere automatisk lasting av kjernemoduler. Denne tiln\u00e6rmingen gj\u00f8r det mulig \u00e5 beskytte systemet proaktivt, uten \u00e5 m\u00e5tte laste spesialiserte kjernemoduler eller utf\u00f8re ekstra bakgrunnsprosesser for \u00e5 overv\u00e5ke systemet. <\/p>\n

Ved behov har brukeren muligheten til \u00e5 legge til moduler i hvitelisten som for \u00f8yeblikket ikke er lastet, men som potensielt kan brukes i arbeidet. Profiler som tillater bruk av de mest n\u00f8dvendige modulene for typiske anvendelser i systemet, er ogs\u00e5 tilgjengelige for aktivering. Profilene \"minimal\" (bare de viktigste modulene og grunnleggende FS), \"konservativ\" (+ typiske drivere for servere og virtual machines<\/a>) og desktop (+ drivere for WiFi, Bluetooth, lyd og video).
