Secure out of the box

All Canonical products are built with unrivalled security in mind — and tested to ensure they deliver it. Your Ubuntu software is secure from the moment you install it, and will remain so as Canonical ensures security updates are always available on Ubuntu first.

Hardening at scale

The default configuration of Ubuntu LTS releases balances between usability, performance and security. However, non general purpose systems can be further hardened to reduce their attack surface. Canonical provides certified tooling for automated audit and hardening. Comply with widely accepted industry hardening profiles, including CIS and DISA-STIG.

Canonical puts security at the heart of Ubuntu

  • Fast fixes

    No system is 100% secure and vulnerabilities will always arise. What matters is the speed and success with which they are resolved — and nobody makes fixes available faster than Canonical.

  • Automatic updates

    Security updates are provided for ten years for long term support (LTS) releases. With the default configuration for unattended upgrades (16.04 and after), these updates get applied to your system automatically.

  • Livepatch

    The Ubuntu Livepatch Service enables live automatic security fixes to the kernel without rebooting. This service reduces unplanned downtime while maintaining compliance and security.

  • 10 years of support

    A new LTS (Long Term Support) version of Ubuntu is released every two years, for desktop and server. Both versions receive updates and are supported for ten years.

  • Expanded security

    Canonical offers Expanded Security Maintenance (ESM) for infrastructure and applications to provide kernel livepatches and vulnerability fixes through a secure and private archive.

  • FIPS

    Ubuntu provides you with FIPS 140 certified cryptographic packages enabling Linux workloads to run on U.S. government regulated and high security environments.

  • Designed to be secure

    Linux is based on Unix. It inherits Discretionary Access Control and includes Mandatory Access Control via AppArmor.

  • Protected VMs

  • Secure snap packages

    Software packages delivered as strict-mode snaps are fully confined using AppArmor, device cgroups, and seccomp.

Helping you manage security

Every Long Term Support (LTS) release of Ubuntu comes with five years of free security and maintenance updates for the main OS. Canonical also offers a number of additional products and services to help manage the security of your Ubuntu systems.

Reduce downtime and unplanned work

The Ubuntu Livepatch service eliminates the need for unplanned maintenance windows for high and critical severity kernel vulnerabilities by patching the Linux kernel while the system runs. Reduce fire drills while keeping uninterrupted service with Ubuntu Livepatch service for up to ten years.

Be compliant and FIPS certified

Developing and running workloads for high security and government regulated environments requires a long and expensive validation process. Reduce your accreditation timeline and pass on your validation costs with the FIPS 140 and Common Criteria certifications available with Ubuntu Advantage and Pro.
