Linux ima integrity measurement architecture

NettetCurrently, IMA does not provide a generic function for kernel subsystems to measure their critical data. Examples of critical data in this context could be kernel in-memory r/o structures, hash of the memory structures, or data that represents a linux kernel subsystem state change.

Nettet1. nov. 2024 · Extending the protection from malicious boot attacks via Integrity Measurement Architecture (IMA) on Linux Linux systems follow a similar boot process to Windows, and with TPM attestation the protection profile can be extended to beyond boot into the kernel as well using Integrity Measurement Architecture (IMA). NettetIMA functions such as ima_match_keyring(), process_buffer_measurement(), ima_match_policy() etc. handle data specific to keyrings. Currently, these constructs are not generic to handle any func specific data. This makes it harder to extend them without code duplication. clouth areal köln https://salermoinsuranceagency.com
