Canonical has been supporting Ubuntu in this way since 2004.

Every two years, the April release is designated a Long Term Support version, which means that Canonical will provide updates and security fixes for software packages for 5 years. Bionic Beaver) and a release number reflecting the year and month it was produced. They are developed by separate groups, and then it’s up to a publisher like Canonical to bundle all the software that people might need together into a single distribution Ubuntu provides many thousands of the most popular applications and software packages in the latest Jammy Jellyfish release.Ī new version of Ubuntu is released every 6 months, in April and October, with a friendly name (e.g. The Linux kernel is the beating heart of the operating system, but it runs behind the scenes – all the applications that we use every day, such as a web browser, email program, card games, developer tools etc, run on top of the kernel. Linux is equally at home powering a laptop as running a mission-critical application in the cloud or on your servers. There are numerous variations of open-source licences, but they all generally permit this model of open collaboration and distribution. It’s typically developed in a collaborative fashion by coders from around the world. Open source means that the software is published with a licence that allows anyone to look at the source code, modify and distribute it as they wish. In 2004, Mark Shuttleworth founded Canonical to produce the Ubuntu distribution, and Canonical has published a new Ubuntu release every 6 months since then. Linux refers to a group of operating systems which are built from open-source software and the Linux kernel, bundled together into a Linux distribution. Therefore, it’s extremely important to consider the state of security of the operating system of end point devices, and to use the most secure operating system possible. So why does the security of user-level applications depend on the security of its underlying system software? The reason is the hierarchical architecture of commodity devices: privileged system software gets unrestricted access to all the resources of unprivileged user-level applications, because it controls its execution, memory, and access to the underlying hardware.

Similarly, it matters little if your code has no buffer overflows, if your operating system is backdoored and simply decides to leak all your customers’ data to malicious third parties. To put it differently, it matters little if a user chooses a perfectly strong unique password, when their operating system is infected with a keylogger leaking it to malicious third-parties. Within this context, system software includes the operating system, virtual machine manager and all the platforms’ firmware embedded within. They will be threatened by the millions of lines of code which comprise the platform’s privileged system software, if it becomes either malicious or compromised.

Pal’s the best, isn’t he? Unfortunately, while such efforts are essential, they are insufficient! And even if we assumed, for the sake of argument and humour, that the PalBank’s client web app is completely free of all known and unknown software vulnerabilities, the app’s security guarantees are bound to be threatened once consumers run it on their endpoint devices. Pal invests considerable effort into designing and implementing the most secure app reasonably achievable: tightly controlled and secure development, build and deployment pipelines, static code analysis, pen-testing by external parties, multi-factor authentication to access the app and encrypting data at rest. For the next 6 months, Pal will be responsible for leading the development of the bank’s web application client, which will be used daily by millions of customers. Pal is a senior developer working at PalBank. Operating system security is the upper bound of your application security
