PureBoot, the High Security Boot Process

Security

The boot process, in computer hardware, forms the foundation for the security of the rest of the system. Security, in this context, means a “defense in depth” approach, where each layer not only provides an additional barrier to attack, but also builds on the strength of the previous one. Attackers do know that if they can compromise the boot process, they can hide malicious software that will not be detected by the rest of the system. Unfortunately, most of the existing approaches to protect the boot process also conveniently (conveniently for the vendor, of course) remove your control over your own system. How? By using software signing keys that only let you run the boot software that the vendor approves on your hardware. Your only practical choices, under these systems, are either to run OSes that get approval from the vendor, or to disable boot security altogether. In Purism, we believe that you deserve security without sacrificing control or convenience: today we are happy to announce PureBoot, our collection of software and security measures designed for you to protect the boot process, while still holding all the keys.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
