Ubuntu 24.10 to Introduce User-Controlled Permissions Prompts

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Specific configuration is an implementation, as are hooks they may add to their own software to leverage features. Both Debian and Ubuntu also build their own profiles.
I see. Interesting. In my case AppArmor seems to be enabled by default under Linux Mint. As well as under my Ubuntu Server. I might need to look into this better, it looks like an important topic that many people overlooked.
It says for example "107 processes are in enforce mode". But also.. 4 profiles are in complain mode..
It’s probably something most people could learn a bit more about. On Red Hat or Fedora you don’t have to get too far out of vanilla before SELinux starts breaking things (oh, you wanted your custom systemd service to run that binary from that directory? Tough! Figure it out!), in comparison AppArmor on Ubuntu and Debian seems to get in the way a lot less. I’m not sure if that’s due to how it functions as a product or upfront work to configure it to be less intrusive.
That is very correct. SELinux is an alternative to AppArmor. But SELinux is much more secure but that comes with a cost. And that is the cost you just described. SELinux is much more advanced and gives you much more control.
