Razvija\u010di iz kompanije Microsoft predstavili<\/a><\/noindex> mehanizam za provjeru integriteta IPE<\/a><\/noindex> (Integrity Policy Enforcement), implementiran kao LSM modul (Linux Security Module) za Linux jezgro. Modul omogu\u0107ava definiranje op\u0107e politike osiguranja integriteta za cijeli sustav, koja navodi koje operacije su dopu\u0161tene i na koji na\u010din treba provjeriti autenti\u010dnost komponenti. Pomo\u0107u IPE-a mo\u017ee se specificirati koje izvr\u0161ne datoteke smiju biti pokrenute i garantirati da su te datoteke identi\u010dne verziji koju je pru\u017eio provjereni izvor. Kod otvoren<\/a><\/noindex> pod MIT licencom.<\/p>\n

IPE je usmjeren na stvaranje potpuno provjerljivih sustava \u010dija je cjelovitost potvr\u0111ena od inicijalnog boot loadera i jezgra do kona\u010dnih izvr\u0161nih datoteka, konfiguracija i u\u010ditanih datoteka. U slu\u010daju izmjene ili zamjene datoteke, IPE mo\u017ee blokirati operaciju ili evidentirati \u010dinjenicu kr\u0161enja integriteta. Predlo\u017eeni mehanizam mo\u017ee se koristiti u firmverima za ugra\u0111ene ure\u0111aje, gdje je sav softver i postavke posebno prikupljene i pru\u017eene od strane vlasnika; na primjer, u data centrima Microsoft IPE se koristi u opremi za vatrozid.<\/p>\n

Od drugih sustava za provjeru integriteta, kao \u0161to su IMA<\/a><\/noindex>, IPE se razlikuje neovisno o metapodacima u FS \u2014 sve karakteristike koje odre\u0111uju valjanost operacija pohranjuju se izravno u kernelu. Za verifikaciju cjelovitosti sadr\u017eaja datoteka koriste se ve\u0107 postoje\u0107i mehanizmi u kernelu zasnovani na kriptografskim hash vrijednostima.
\ndm-verity<\/a><\/noindex> ili fs-verity<\/a><\/noindex>.
\nNa sli\u010dan na\u010din kao sa SELinux, podr\u017eavaju se dva na\u010dina rada \u00abpermissive\u00bb i \u00abenforce\u00bb. U prvom na\u010dinu samo se prati log problema pri izvr\u0161avanju provjera, \u0161to se, na primjer, mo\u017ee koristiti za prethodno testiranje okru\u017eenja.<\/p>\n
