Dedicated to the security of Ubuntu

Since its inception in 2004, Ubuntu has been built on a foundation of enterprise-grade, industry leading security practices. From our toolchain to the suite of packages we use and from our update process to our industry standard certifications, Canonical never stops working to keep Ubuntu at the forefront of safety and reliability.

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.

Certified compliance

Canonical offers a range of tools to enable organisations to manage their desktop fleet and cloud with specific compliance requirements. A FIPS (Federal Information Processing Standard) certified version of Ubuntu is also available to comply to US government standards.

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.

  • Extended security

    For users of Ubuntu 14.04 and 16.04 LTS, Canonical offers Extended Security Maintenance (ESM) to provide vulnerability fixes and livepatches through a secure and private archive.

  • FIPS

    Ubuntu is certified to US government standards by FIPS (Federal Information Processing Standard) to ensure compliance and tougher security.

  • Designed to be secure

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

  • Protected VMs

    LXD containers, libvirt VMs and OpenStack VMs are protected by AppArmor by default. A rich set of profiles are provided so users can opt-in to protection for other applications.

  • 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. 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.
