  • Security updates for Friday

    Security updates have been issued by Arch Linux (lib32-openssl), Debian (git), Gentoo (chromium, firefox, git, and openssl), Oracle (kernel and python-twisted-web), Red Hat (python-twisted-web), Scientific Linux (python-twisted-web), and SUSE (file-roller, kernel, and resource-agents).

  • NSA, ASD publish advisory for detecting and mitigating web shell malware

    The US National Security Agency (NSA) and the Australian Signals Directorate (ASD) have released a joint security guidance on techniques that can be used detect and prevent web shell malware from affecting web servers.

    Malicious web shells have been a threat for several years, according to NSA, and can be deployed on a compromised internal or internet-facing server to gain or retain access on compromised networks.

    Hackers use these programmes to execute arbitrary system commands, which are usually sent over HTTPS. They also allow threat actors to deliver additional malware payloads on infected servers and to pivot to other machines within the network.

  • Security Flaws Found in Three Home Hubs

    Home hubs are a double-edged sword when it comes to security. They let you access any device in the home. At the same time, anyone who breaches the hub’s security can also do the same. This makes a central hub key in defending a smart home, as a compromised hub is a critical flaw in any setup. Unfortunately, ESET IoT Research has recently found that three home hubs have severe security flaws. As such, owners of these home hubs should consider updating or replacing their devices as soon as possible.

  • Recovering a breached Linux system

    No one wants their systems to be breached. No one wants their data stolen. And no one wants to recover a breached system. Neither discovery nor recovery are fun activities. In fact, I'd have to say that of all the horrible tasks facing you as a sysadmin, recovering a system from a malicious attack is the worst. In this article, I give you 12 steps to system recovery, some post-mortem tips, and a last resort option after you find that one or more of your systems has been compromised or breached.

  • Ubuntu Core: a cybersecurity analysis

    Manufacturers of Internet of Things (IoT) devices require an embedded operating system that is feature-rich, scalable, and — most importantly — secure. Built from the ground-up to meet these requirements, Ubuntu Core represents a comprehensive ecosystem for large-scale IoT deployments that solves many of the security challenges associated with traditional Linux distribution models — while also empowering developers with unprecedented flexibility and control.

    This whitepaper from global cybersecurity experts, Rule4, provides an independent, third-party evaluation of Ubuntu Core’s security capabilities. Following a data-driven approach, all aspects received extensive testing to validate the strengths of its cybersecurity controls.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
