Detect Offline Disk Manipulation
dm-verity
Makes sure every single sector on a block
device is authenticated.
It has little overhead but allows no writes!
dm-integrity
Like dm-verity, but offers full read-
write access.
It has more overhead since it needs to
maintain a journal!
#Security #Linux
🐧 Linux provides numerous methods to detect offline manipulation of disk data. For block devices, it is recommended to use dm-verity and dm-integrity. 🛡️ This way, entire partitions and their filesystems can be safeguarded against malicious tampering.
