Linux File System Permissions

Hi and welcome to this new video! In this video we continue the "Linux Privilege Escalation" series. This time the focus will be on file system permissions. In the video we will discuss how file system permissions are handled within linux, we will see how to read permission and interpret their meaning, as well as how to write permissions to a given resource (file or directory), to set new permissions. Finally, we will discuss about the special bits SUID and GUID, and the sudo subsystem. I hope you find it helpful, and I would appreciate if you leave your feedback down in the comments, and share this series with like-minded people.
