上海天天彩选四网址:Dedicated to the security of Ubuntu
上海天天彩选四公式 www.uhh3o.cn 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.
Secure by process
Canonical’s team of security experts react fast to threats constantly reviewing and fixing vulnerabilities. They also develop security features and best practices that are rolled into all Canonical products.
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.

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.
Security updates are provided for five 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.
The Canonical Livepatch Service enables live automatic security fixes to the kernel without rebooting. This service reduces planned or unplanned downtime while maintaining compliance and security.
5 years of support guaranteed
A new LTS (Long Term Support) version of Ubuntu is released every two years, for desktop and server. Both versions are supported for five years.
For users of Ubuntu 14.04 LTS, Canonical offers Extended Security Maintenance (ESM) to provide ongoing kernel security fixes through a secure and private archive.
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.
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 www.uhh3o.cnes 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.
Critical security fixes with zero downtime
The Canonical Livepatch Service lets you apply kernel fixes in seconds, without restarting your Ubuntu 18.04 LTS, 16.04 LTS or 14.04 ESM systems. Fewer reboots removes the operational burden associated planned downtimes for upgrades. It also means improved service availability and systems that are more compliant and secure.
Be compliant and FIPS certified
FIPS (Federal Information Processing Standard) is a US Government standard for ensuring compliance and security that mandates tougher encryption keys and only allows approved cryptographic functions.
Ubuntu 16.04 LTS has achieved FIPS certification for the OpenSSL, Kernel Crypto API, OpenSSH (Server, Client), and Strongswan modules. FIPS certified versions of these modules are available to Ubuntu Advantage Advanced customers.
Manage security updates with Landscape
Landscape is the leading management tool to deploy, monitor and manage your Ubuntu servers and desktops. Landscape gives the ability to centrally view and manage the security updates that have been applied to their systems and, critically, the security updates which have not yet been applied.
Extend your Ubuntu 14.04 LTS security maintenance
Following the end-of-life of Ubuntu 14.04 LTS in April 2019, Canonical began offering Ubuntu 14.04 ESM (Extended Security Maintenance), to Ubuntu Advantage customers to provide important security fixes for the kernel and essential user space packages. These updates are delivered via a secure, private archive exclusively available to Ubuntu Advantage customers.
All of our security products are available for a one off fee or they are all included in our Ubuntu Advantage support packages.
