  • Linux Kernel Live Patching: What It Is and Who Needs It

    Live patching is a way of updating a running system without stopping it. It is best known as a technique for keeping Linux servers updated to the latest security levels without affecting downtime. This article provides some background to the technique and explains the advantages of using it.

    What is Live Patching?

    Live patching lets you keep Linux server kernels up-to-date with the latest security updates without the need to reboot. Although the practice is a decade old – once seen as a convenience tool easing the lives of system administrators – it is now coming to the attention of security managers and CISOs in the wake of the recent flurry of Linux-related kernel vulnerabilities.

    Until the advent of live security updates, server managers had to choose between running their systems with known vulnerabilities, or taking their servers down to install security updates. System administrators now see Linux kernel live security updates are becoming an essential component of an enterprise’s cybersecurity toolkit, not merely a convenience for system maintainers.

  • Security updates for Friday

    Security updates have been issued by Arch Linux (chromium, opensc, opensmtpd, and weechat), Debian (jackson-databind and pdfresurrect), Fedora (sudo), openSUSE (openfortivpn and squid), Red Hat (virt:8.1 and virt-devel:8.1), Scientific Linux (http-parser and xerces-c), and SUSE (gd, kernel, postgresql10, and tomcat).

  • Intel chipsets have another security issue, this time it's 'unfixable'

    Researchers have uncovered a fun new vulnerability in Intel processors, and this one has a claim attached that it's not possible to fix it.Sound familiar? Yeah, there's been a lot of problems over at Intel in the last couple years. We reported on some back in January and it seems it's not getting any better.

    This issue, found and reported by Positive Technologies, mentions CVE-2019-0090 which as the numbered year suggests was already announced last year. However, the plot thickens. If you have an Intel chipset and/or SoC older than the 10th Generation (so anything in the last few years), you will be affected by this.

  • 'Unfixable' boot ROM security flaw in millions of Intel chips could spell 'utter chaos' for DRM, file encryption, etc.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
