The Driver for the Scull_Open Discovery Function, Read / Write Scull_Read / Scull_Write For a Protected Linux OS
Journal Title: International Journal of Computer Science Engineering and Information Technology Research (IJCSEITR) - Year 2019, Vol 9, Issue 1
Abstract
In this article the principle of implementing a special-purpose device driver for secure Linux operating systems, using the example of a simple character driver is discussed. The main goal is to summarize and form the basic knowledge for writing future kernel modules. To interact with the equipment or perform operations with access to privileged information, the system needs a kernel driver. The Linux kernel module is a compiled binary code that is inserted directly into the Linux kernel, the internal and the least secure shell of executing instructions in the x86-64 processor. Here the code is executed completely without any checks, but at an incredible speed and with access to any system resources. Changing the kernel, you run the risk of losing data. The kernel code does not have standard protection, as in normal Linux applications.
