7 Reasons Why Ubuntu 22.04 LTS is the Most Secure Release Yet
======
Ubuntu 22.04 LTS is one of the best Ubuntu releases so far. What makes it so secure?
[Ubuntu 22.04 LTS][1], released back in April, is the most secure Ubuntu release yet.

With this release, it seems that the Ubuntu team has put a lot of work into ensuring its long-term security and reliability. Although they did this in an unthinkable number of ways over the years, I shall highlight a few things that include:
* Improved hardware security measure support
* Updated security packages
* Private home directories
* OpenSSL 3
* GCC 11
* nftables as the default firewall backend

With every Ubuntu release, Linux Kernel gets an upgrade with many useful features and support.

Not just limited to this concept, some essential kernel security enhancements mentioned in the [blog post][5] include:

* _Kernel stack randomisation provides a hardening measure to frustrate attackers wishing to perform memory corruption attacks within the kernel._
* _The BPF subsystem has also seen a number of security enhancements including restricting its use to only privileged processes by default, as well as including the initial efforts to support signed BPF programs as well_
* *The inclusion of the new Landlock Linux Security Module provides another mechanism for application sandboxing to go along with the more traditional methods via either AppArmor or SELinux. *

Stepping back from technical security concepts, we get to a concept every Ubuntu user should be already familiar with: packages. With every new Ubuntu release, most packages in the repositories get updated, bringing improved security and new features.
