The prizrak.me blog is carrying an introduction to the Landlock security module.

Landlock shines when an application has a predictable set of files or directories it needs. For example, a web server could restrict itself to accessing only /var/www/html and /tmp.

Unlike SELinux or AppArmor, Landlock policies don't require administrator involvement or system-wide configuration. Developers can embed policies directly in application code, making sandboxing a natural part of the development process.
