  • OpenStack Cloud Security Moves Forward

    When it comes to understanding security in the cloud and specifically security in OpenStack clouds, there are many factors to consider. In a panel session moderated by eWEEK at the OpenStack Summit in Boston, leaders from across different elements of the OpenStack security spectrum provided insight and recommendations on cloud security.

    Security is a broad term in the OpenStack context and isn't just one single item. There is the OpenStack Security Project, which has a mission to help build tools and processes that help to secure OpenStack and its various projects. There is also the Vulnerability Management Team (VMT) that handles vulnerabilities for OpenStack project. Security in OpenStack is also reflected in various OpenStack projects, including notably Project Barbican for security key management. Finally there is just general security for cloud deployment by operators, which includes secure configuration and monitoring.

  • We Wuz Warned

    The tools that are infecting computers worldwide were indeed developed by, and then leaked from, the NSA. (Thanks for nothing, spooks.) The bitcoin.com article contains tips about how to protect yourself, and links to Windows patches, if you haven't yet been hit. Fortunately for us, the attacks seem to be focused on Windows systems; our Linux desktops are so far unscathed.

  • NSA-created cyber tool spawns global attacks — and victims include Russia

    Leaked alleged NSA hacking tools appear to be behind a massive cyberattack disrupting hospitals and companies across Europe, Asia, with Russia among the hardest-hit countries.

    But the Department of Homeland Security told POLITICO it had not confirmed any attacks in the U.S. on government targets or vital industries, such as hospitals and banks.

  • GCHQ tweeted about keeping Britain cyber-safe and it majorly backfired
  • Leaked NSA Hacking Tool On Global Ransomware Rampage [Ed: No, the problem isn't "patching" or "upgrade", the problem is Windows itself, irrespective of which version (back doors)]

    Thus, there's some debate online about whether the "problem" here is organizations who don't upgrade/patch or the NSA. Of course, these things are not mutually exclusive: you can reasonably blame both. Failing to update and patch your computers is a bad idea these days -- especially for large organizations with IT staff who should know better.

  • An NSA-derived ransomware worm is shutting down computers worldwide
  • WCry is so mean Microsoft issues patch for 3 unsupported Windows versions [Ed: Back doors in old versions of Windows belatedly closed because Microsoft risks losing millions of useds [sic] for good]

How To Encrypt DNS Traffic In Linux Using DNSCrypt

​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. Read

Debian-Based Untangle 13.0 Linux Firewall Tackles Bufferbloat, Adds New Features

Untangle NG Firewall, the open-source and powerful Debian-based network security platform featuring pluggable modules for network apps, has been updated to version 13.0, a major release adding new features and numerous improvements. The biggest improvement brought by the Untangle NG Firewall 13.0 release is to the poor latency generated by excess buffering in networking equipment, called bufferbloat, by supporting a queueing algorithm designed to optimize QoS and bandwidth to enforce a controlled delay.

Kernel Space: HMM, Cloud Native, Linux 4.12, TFS, Linux 4.11.2, and 4.10 EoL

  • 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.

ROSA Fresh R9

ROSA is a desktop distribution that was originally forked from Mandriva Linux, but now is independently developed. While the company which produces ROSA is based in Russia, the distribution includes complete translations for multiple languages. The ROSA desktop distribution is designed to be easy to use and includes a range of popular applications and multimedia support. ROSA R9 is available in two editions, one featuring the KDE 4 desktop and the second featuring the KDE Plasma 5 desktop. These editions are scheduled to receive four years of support and security updates. I decided to download the Plasma edition of ROSA R9 and found the installation media to be approximately 2GB in size. Booting from the ROSA disc brings up a menu asking if we would like to load the distribution's live desktop environment or begin the installation process. Taking the live option brings up a graphical wizard that asks us a few questions. We are asked to select our preferred language from a list and accept the project's warranty and license. We are then asked to select our time zone and keyboard layout from lists. With these steps completed, the wizard disappears and the Plasma 5.9 desktop loads. Read more
