Security: Updates, DNS Features in IPFire, Shodan and Canonical's Role in Robot Operating System (ROS 2)

Security
  • Security updates for Wednesday

    Security updates have been issued by Debian (python-pysaml2), Mageia (clamav, graphicsmagick, opencontainers-runc, squid, and xmlsec1), Oracle (kernel, ksh, python-pillow, systemd, and thunderbird), Red Hat (rh-nodejs12-nodejs), Scientific Linux (ksh, python-pillow, and thunderbird), and SUSE (nodejs6, openssl, ppp, and squid).

  • What you can do with the new DNS features in IPFire

    Every time you try to access a website - for example ipfire.org - you will ask a DNS server for the IP address to connect to. They won't see anything past "the slash" in the URL, but that is not necessary to know what you probably have in mind to do. That DNS server now knows which bank you are with, where you work, where you do your online shopping, who is hosting your emails and many things more...

    Although this data is not too interesting about one individual, it becomes very relevant when you are looking at many profiles. People who shop at a certain place or are with a certain bank might be high earners. People who shop at another place might have trouble to stay afloat financially. Now I know what advertisements I need to show to which group so that they will become my customers.

    In short, your whole browser history tells a lot about you and you might be giving it away for free to the advertising industry or other parties who will use your data against you.

  • How Shodan Has Been Improved to Help Protect Energy Utilities

    Shodan is a well-known security hacking tool that has even been showcased on the popular Mr. Robot TV show. While Shodan can potentially be used by hackers, it can also be used for good to help protect critical infrastructure, including energy utilities.

    At the RSA Conference in San Francisco, Michael Mylrea, Director of Cybersecurity R&D (ICS, IoT, IIoT) at GE Global Research, led a session titled "Shodan 2.0: The World’s Most Dangerous Search Engine Goes on the Defensive," where he outlined how Shodan has been enabled to help utilities identify risks in critical energy infrastructure. Shodan, to the uninitiated, is a publicly available search engine tool that crawls the internet looking for publicly exposed devices.

    Mylrea explained that utilities are often resource constrained when it comes to cybersecurity and are typically unaware of their risk. In recent years, there have been a number of publicly disclosed incidents involving utilities. To help solve that challenge, Mylrea proposed a project to the US Department of Energy (DoE) to enhance Shodan for utilities so they could use the tool to find risks quickly.

  • Canonical takes leadership role in security for ROS

    Canonical is committed to the future of robotics, as proven a short time ago when we joined the Technical Steering Committee of the second version of the Robot Operating System (ROS 2). We’re also dedicated to building a foundation of enterprise-grade, industry leading security practices within Ubuntu, so we’re excited to join both of these strengths with our own Joe McManus taking the helm of the ROS 2 Security Working Group.

    We believe robots based on Linux are cheaper to develop, more flexible, faster to market, easier to manage, and more secure. While ROS began as an academic project over a decade ago, it has grown to become the most popular middleware for creating Linux-powered robots. It has harnessed the power of open source, allowing for many of the complex problems faced by robotics to be solved through collaboration. The ROS developer community has continued to grow, and ROS now enjoys an increasing amount of commercial use and supported robots. In response, the ROS community has completely overhauled the ROS codebase and started distributing ROS 2.

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.
