Cel szkolenia szkolenie zdalne - dlearning

kod: LFD440

This instructor-led course focuses on the important tools used for debugging and monitoring the kernel, and how security features are implemented and controlled.

This course is for experienced developers who need to understand the methods and internal infrastructure of the Linux kernel.

This four day course includes extensive hands-on exercises and demonstrations designed to give you the necessary tools to develop and debug Linux kernel code.

You will walk away from this course with a solid understanding of Linux kernel. debugging techniques and tools.
