Canonical has released the latest version of its Ubuntu Linux distribution which offers a number of exciting new features designed to improve performance and security.
Ubuntu 20.04, aka Focal Fossa, is based on the Linux 5.4 kernel and this long-term-support (LTS) version is a major update for desktop, server and cloud users.
Linux 5.4 includes an optional Linux Security Module (LSM) called kernel lockdown mode which prevents the system's root account from altering the kernel code in some instances. This makes it much more difficult for compromised root accounts to compromise Linux systems.
