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 TechThe 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. |
