Therefore, validating the file system’s structure, contents, and permissions is essential for determining if a device has been compromised.
The implementation of file system integrity checks typically involves calculating cryptographic hashes of critical system files and directories. These hashes are then compared against a known-good baseline, established when the system was in a trusted state. Discrepancies between the calculated hashes and the baseline indicate that the corresponding files have been modified. Techniques such as file whitelisting and rootkit detection are also employed to identify unauthorized or hidden files. An instance of this involves a security application scanning the `/system/bin` directory on an Android device, comparing the SHA-256 hashes of executables against a database of known legitimate files. Any executables with mismatched hashes would be flagged as potentially malicious.
In summary, file system integrity validation serves as a cornerstone in detecting mobile device compromises. By implementing and regularly executing code to verify file integrity, administrators and users can identify and mitigate potential security breaches. Challenges include maintaining accurate baselines, adapting to legitimate system updates, and addressing advanced techniques used by malware to conceal file modifications.
