An Instruction Blocking Methods for Disk Data Protection

Abstract

Disk data is frequently subject to malicious tampering attacks, causing huge losses to computer users. The existing disk data protection technology mainly protects data at the file system layer, the general block layer, the driver layer, and the hardware layer, and cannot protect against attacks at the disk controller layer. Aiming at this phenomenon, this paper proposes an instruction blocking method for disk data protection based on disk controller. By acquiring and analyzing computer runtime instructions, the method combines disk controller and binary cartridge techniques to modify and block malicious instructions that write to protected disk sectors, making them non-malicious. Experimental results show that this method can effectively protect the data in the specified area of the disk from malicious tampering.
