Gli sviluppatori di Microsoft hanno presentato<\/a><\/noindex> meccanismo di controllo dell'integrit\u00e0 IPE<\/a><\/noindex> (Integrity Policy Enforcement), implementato come modulo LSM (Linux Security Module) per il kernel Linux. Il modulo consente di definire una politica generale di protezione dell'integrit\u00e0 per l'intero sistema, indicando quali operazioni sono consentite e in che modo deve essere verificata l'autenticit\u00e0 dei componenti. Con IPE \u00e8 possibile specificare quali file eseguibili possono essere avviati e garantire che questi file siano identici alla versione fornita da una fonte attendibile. Il codice \u00e8 open source<\/a><\/noindex> sotto licenza MIT.<\/p>\n

IPE mira a creare sistemi completamente verificabili, la cui integrit\u00e0 \u00e8 confermata dal bootloader iniziale e dal kernel fino ai file eseguibili finali, alle configurazioni e ai file caricati. In caso di modifica o manomissione di un file, IPE pu\u00f2 bloccare l'operazione o registrare il fatto della violazione dell'integrit\u00e0. Il meccanismo proposto pu\u00f2 essere applicato nei firmware per dispositivi integrati, in cui tutto il software e le impostazioni sono appositamente assemblati e forniti dal proprietario, ad esempio, nei data center Microsoft IPE \u00e8 utilizzato nell'hardware per firewall.<\/p>\n

Rispetto ad altri sistemi di controllo dell'integrit\u00e0, come IMA<\/a><\/noindex>, L'IPE si distingue per la sua indipendenza dai metadati nel FS \u2014 tutte le propriet\u00e0 che definiscono l'ammissibilit\u00e0 delle operazioni sono memorizzate direttamente nel kernel. Per la verifica dell'integrit\u00e0 del contenuto dei file tramite hash crittografici vengono applicati meccanismi gi\u00e0 esistenti nel kernel.
\ndm-verity<\/a><\/noindex> o fs-verity<\/a><\/noindex>.
\nAnalogamente a SELinux, sono supportate due modalit\u00e0 operative: \u00abpermissiva\u00bb e \u00abenforce\u00bb. Nella prima modalit\u00e0 vengono semplicemente registrati i problemi durante l'esecuzione dei controlli, il che pu\u00f2 essere utilizzato, ad esempio, per il test preliminare dell'ambiente.<\/p>\n
