Before taking this course, I only knew how to simply change permissions using the chmod command. However, through this lecture, I was able to gain a deep understanding of the detailed internal processes and the permission systems involved when an executable binary file is loaded into memory as a process and accesses actual files. Beyond simple permission management, the course covered essential practical topics such as setting up Apache web servers and DB servers, efficient disk management, and firewall settings for security, making it the perfect lecture for grasping the overall context of Linux operations. It was a beneficial time that allowed me to build both a solid foundation and practical skills simultaneously. I am so satisfied with this lecture that I am truly looking forward to the next follow-up course!

Thank you sincerely for your thoughtful review. Since permissions are directly linked to security, they are a very important topic. It is necessary to learn not just isolated commands, but the broader context and practical points as well. Based on my experience and know-how accumulated over nearly 30 years of using Linux, I have done my best to organize and share the core content that will definitely be helpful in the field. I feel a great sense of accomplishment knowing that you have mastered the essential practical content. Although the follow-up lectures will take a lot of time, I will prepare them step-by-step with an even stronger focus on practical application. You can look forward to it. I invested a lot of time preparing this lecture, but looking back, I see areas for improvement. I will continue to update and refine the content to make it more complete, addressing any parts that might be lacking from a student's perspective. Please look forward to the subsequent supplementary materials as well. Thank you. ^^
