I think most of the current Linux supports Access Control List (ACL). With filesystem ACLs enabled, We can set additional permissions to different users or groups. This allows us to set the file system permissions of different users more freely. Go straight to the command.
Detect whether selinux is enabled in the system
For Linux system administrators, you must understand the ps aux command. If you want to be a Linux system administrator, or you are a Linux user, you should understand this command. ps is process status For short, anyone can find out what kind of program is running on the system and how the status is executed through this command. I saw some programs that should not appear, maybe the system was hacked and used to mine🥹
