Security

Conventional security measures like antivirus programs are behind the curve when it comes to modern hackers and malware. Unfortunately, antivirus software and firewalls give users a false sense of security. In reality, new threats are being developed and unleashed into the wild every single day, and even the best antivirus programs have to play catchup.

Recent ransomware attacks (aka. WannaCry) have targeted Windows-based PCs in over 150 countries – cyber security and privacy is incredibly important. Windows and macOS are easy to use and popular; however, they are much more susceptible to malicious code.

Linux is free and open source, which means there are hundreds of “flavors.” These individual distributions are tweaked to different specifications. Security-focused users will be pleased to know that there are a number of Linux distros designed with security and privacy in mind.

  • General Manager of Training at The Linux Foundation Forecasts Cloudy Weather

    Where does The Linux Foundation believe ones time is well spent to catapult their career objectives? It is fairly apparent after reaching out to Clyde Seepersad, General Manager Training and Certification of The Linux Foundation, the cloud is the place to be. When communicating with him on a variety of topics that revolve around The Linux Foundation's certification offerings and education, the central point of focus is the cloud. Clyde provided us with a slew of information about The Linux Foundation's efforts to make sure FLOSS continues to succeed for the foreseeable future.

  • Hughes: Updating Logitech Hardware on Linux

    Logitech has provided firmware updates, but not for "unsupported" platforms like Linux. Hughes has filled that gap by getting documentation and a fixed firmware image from Logitech and adding support for these devices to fwupd. He is now looking for testers to ensure that the whole thing works across all devices. This is important work that is well worth supporting.

  • Updating Logitech Hardware on Linux

    This gave an attacker with $15 of hardware the ability to basically take over remote PCs within wireless range, which could be up to 50m away. This makes sitting in a café quite a dangerous thing to do when any affected hardware is inserted, which for the unifying dongle is quite likely as it’s explicitly designed to remain in an empty USB socket. The main manufacturer of these devices is Logitech, but the hardware is also supplied to other OEMs such as Amazon, Microsoft, Lenovo and Dell where they are re-badged or renamed. I don’t think anybody knows the real total, but by my estimations there must be tens of millions of affected-and-unpatched devices being used every day.

  • An introduction to Libral, a systems management library for Linux

    Linux, in keeping with Unix traditions, doesn't have a comprehensive systems management API. Instead, management is done through a variety of special-purpose tools and APIs, all with their own conventions and idiosyncrasies. That makes scripting even simple systems-management tasks difficult and brittle.

How To Encrypt DNS Traffic In Linux Using DNSCrypt

Filed under
Linux

​Dnscrypt is a protocol that is used to improve DNS security by authenticating communications between a DNS client and a DNS resolver. DNSCrypt prevents DNS spoofing. It uses cryptographic signatures to verify that responses originate from the chosen DNS resolver and haven’t been tampered with. DNSCrypt is available for multi-platforms including Windows, MacOS, Unix, Android, iOS, Linux and even routers.

  • Faster machine learning is coming to the Linux kernel

    Heterogenous memory management (HMM) allows a device’s driver to mirror the address space for a process under its own memory management. As Red Hat developer Jérôme Glisse explains, this makes it easier for hardware devices like GPUs to directly access the memory of a process without the extra overhead of copying anything. It also doesn't violate the memory protection features afforded by modern OSes.

  • Product Development in the Age of Cloud Native

    Ever since the mass adoption of Agile development techniques and devops philosophies that attempt to eradication organizational silos, there’s been a welcome discussion on how to optimize development for continuous delivery on a massive scale. Some of the better known adages that have taken root as a result of this shift include “deploy in production after checking in code” (feasible due to the rigorous upfront testing required in this model), “infrastructure as code”, and a host of others that, taken out of context, would lead one down the path of chaos and mayhem. Indeed, the shift towards devops and agile methodologies and away from “waterfall” has led to a much needed evaluation of all processes around product and service delivery that were taken as a given in the very recent past.

CloudReady - Chromebook re-experienced

Filed under
GNU
Linux
Google

I haven't done any extensive testing, but then, how much testing is really needed to run a bunch of Web apps. The whole idea is to have this cloud-based operating system, with easy, flexible access to your data anywhere you go. So if you judge this from the perspective of a typical desktop, you miss the point.

But that is the point. When I install something on a desktop-like form factor, I expect its behavior to match. CloudReady takes you away from that experience, and the transition is not comfortable. You feel very limited. This makes a lot of sense for schools, for instance, where you do want to lock down the devices, and make them simple for reuse. In a home setup, why would you go for just cloud, when you can have that plus any which desktop application on a typical system? After all, nothing prevents you from launching a browser and using Google applications, side by side with your desktop stuff. It's the same thing.

The notion of reviving old hardware is a bit of a wishful thinking. My eeePC test shows that it gets completely crippled when you run HD content in either Firefox or Chrome. An operating system based on Chromium OS will not drastically change that. It cannot do that. Maybe you will have better performance than having Windows there, the same way I opted for a Linux setup on the Asus netbook, but there are physical limits to what old hardware can accomplish.

And then, there's the whole question of cloud ... Most people might be comfy with this, after having used smartphones for a while, but I don't think this is anything novel or mindblowing. CloudReady works as advertised, it's a very cool concept, but ultimately, it gives you a browser on steroids. Google and Neverware have their own agenda for doing this, but for home users, there really isn't any added value in transforming their keyboard-and-mouse box into a browsing portal. So if you ask me, am I ready for the cloud, the answer is, only when it becomes sophisticated enough to match my productivity and freedom of creativity. And for you, do you want a simple, locked down, secure and entirely Google machine that isn't a mobile phone or a dedicated piece of hardware? The answer is 42.

Intel has launched its “Euclid” robotics compute module, which runs Ubuntu on an Atom x7-Z8700, and offers a RealSense 3D cam, WiFi, and sensors.

When Intel demonstrated its Intel Euclid robotics controller at last August’s Intel Developer Conference, the company gave no indication of its release date or even if it would be more than a proof of concept. The candy-bar sized module is now available for order as part of a $399 Intel Euclid Development Kit, with shipments due by the end of the month. A Euclid community site has gone live with tutorials and documentation.

Servers: Infrakit & LinuxKit, CMTL, ServiceMaster, Synology, Ubuntu, and NeuVector

  • Why Infrakit & LinuxKit are better together for Building Immutable Infrastructure?
    Let us accept the fact – “Managing Docker on different Infrastructure is still difficult and not portable”. While working on Docker for Mac, AWS, GCP & Azure, Docker Team realized the need for a standard way to create and manage infrastructure state that was portable across any type of infrastructure, from different cloud providers to on-prem. One serious challenge is that each vendor has differentiated IP invested in how they handle certain aspects of their cloud infrastructure. It is not enough to just provision n-number of servers;what IT ops teams need is a simple and consistent way to declare the number of servers, what size they should be, and what sort of base software configuration is required. Also, in the case of server failures (especially unplanned), that sudden change needs to be reconciled against the desired state to ensure that any required servers are re-provisioned with the necessary configuration. Docker Team introduced and open sourced “InfraKit” last year to solve these problems and to provide the ability to create a self healing infrastructure for distributed systems.
  • CMTL Testing First Linux Based Intel® Server Board
    The board is designed for HPC workload environments requiring parallel computing processing performance. Up to 72 cores for optional support and 100Gb/s node interconnect. Six slots for DDR4, 2400Mhz registered ECC DIMMS to achieve a capacity of 384G.
  • [Older] DNS Infrastructure at GitHub
    At GitHub we recently revamped how we do DNS from the ground up. This included both how we interact with external DNS providers and how we serve records internally to our hosts. To do this, we had to design and build a new DNS infrastructure that could scale with GitHub’s growth and across many data centers.
  • ServiceMaster polishes DevOps process for Linux container security
    ServiceMaster Global Holdings Inc., which owns consumer brands such as Terminix, Merry Maids, Furniture Medic and ServiceMaster Clean and Restore, deploys 75,000 service trucks to residential driveways each day. Five years ago, the company was taken private by an equity firm, and new leadership, including a new CIO, was brought in to modernize its operations. When it returned to the public market in 2014, the company had completely overhauled its approach to IT.
  • My Love Affair with Synology
    In my "Hodge Podge" article in the October 2016 issue, I mentioned how much I love the Synology NAS I have in my server closet (Figure 1). I got quite a few email messages from people—some wanting more information, some scolding me for not rolling my own NAS, and some asking me what on earth I need with that much storage. Oddly, the Linux-running Synology NAS has become one of my main server machines, and it does far more than just store data. Because so many people wanted more information, I figured I'd share some of the cool things I do with my Synology.
  • Certified Ubuntu Cloud Guest – The best of Ubuntu on the best clouds
    Ubuntu has a long history in the cloud. It is the number one guest operating system on AWS, Azure and Google Cloud Platform. In fact there are more Ubuntu images running in the public cloud than all other operating systems combined. Ubuntu is a free operating system which means anyone can download an image, whenever they want. So why should cloud providers offer certified Ubuntu images to their customers?
  • Cloud Foundry and Kubernetes: Different Tools
    It’s difficult to compare programming languages and platforms, of course, but this was the analogy that most frequently came to mind last week. Cloud Foundry is unlikely to be as popular as it was shortly after it launched, when it was the only open source PaaS platform available. But this says little about Cloud Foundry, and more about the platform market which – like every other infrastructure market – is exploding with choice to the point of being problematic. It also ignores the ability for the Cloud Foundry foundation to actively embrace this choice via the addition of Kubo.
