CAINE 9.0 Linux Helps Investigators With Computer Security Forensics

Filed under
Linux
Security

While there are many security-focused Linux distributions on the market, one distribution distinguishes itself by targeting forensic investigators. Instead of penetration testing tools, CAINE - which is an acronym for Computer Aided INvestigative Environment and was investigated to version 9.0 on Oct. 25 - is loaded with applications and tools to help investigators find the clues and data points that are required for computer security forensics.

Filed under
Linux

Digilent’s “Zybo Z7” SBC runs Linux on the Xilinx Zynq-7010 and -7020 ARM/FPGA SoCs, and offers HDMI in and out, MIPI-CSI, and up to 6x Pmod connectors.

Digilent, which is owned by National Instruments, is known for its FPGA-driven Pmod peripheral modules and Arty FPGA development board. In 2012, the company also launched a Zybo board supporting the lowest end Xilinx Zynq-7010 version of the Zynq family, which combines dual Cortex-A9 cores running Linux with an FPGA. Now Digilent has introduced a more capable Zybo Z7 board aimed at embedded vision applications. The Zybo Z7 offers an option for the Zynq-7020, which has a faster FPGA, as well as enhancements including the addition of a MIPI-CSI camera interface and separate HDMI in and out ports.

  • Linux User Management as a Service

    Managing Linux users has been an interesting topic in the identity management world. Early on, Linux machines weren’t that popular, so the management of the associated users was handled manually. But now, as Linux becomes more commonplace, controlling access to Linux systems is an important aspect for most IT admins to have covered. Fortunately, a new generation of Linux user management has arrived – and it simplifies the task for IT by coming in the ‘as a service’ form.

  • Intel User-Mode Instruction Prevention Support Revised For The Linux Kernel

    An Intel engineer over the weekend sent out the latest patches for implementing the company's User-Mode Instruction Prevention (UMIP) support within the Linux kernel.

    User-Mode Instruction Prevention appears to be on track for upcoming Cannonlake processors and prevents certain instructions from being executed if the ring level is greater than zero. These instructions include the store task register, store machine status word, store global descriptor table, and store interrupt descriptor table. To fend off possible escalation attacks, Intel's UMIP security feature will prevent these instructions from being executed outside of the highest level privileges.

As expected for a new stable series, Enlightenment 0.22 is a major release bringing great improvements, new features, and countless bug fixes. And we'll start with the support for the next-generation Wayland display server, which was greatly improved in this release, adding support for relative pointer motion protocols, pointer constraints, and xdg-shell v6.

"The majority of development for this cycle has gone towards improving Wayland support," said Mike Blumenkrantz in the release notes. "This covers, but is not limited to: adding support for xdg-shell v6, pointer constraints, and relative pointer motion protocols. These additions improve XWayland support and increase stability across all components running under Wayland."

Linux Kernel 3.10 Reached End of Life, Users Are Urged to Move to Linux 4.4 LTS

Filed under
Linux

The end of life was reached this past weekend with the release of Linux kernel 3.10.108, which is the last maintenance update for the Linux 3.10 branch. Therefore, users and OEMs are now urged to upgrade to a more recent, long-term supported Linux kernel, such as the Linux 4.4 LTS series.

"It is the last one in this branch and changes the status of the 3.10 branch to end of life. Thus for once I'm *not* suggesting to upgrade to this one, except if it's just to finish your migration to a newer branch (such as 4.4)," said Willy Tarreau in the mailing list announcement.

Programming: Swift, Brilliant Jerks in Engineering, and Career Path for Software Developers

  • Swift code will run on Google's Fuchsia OS
    A few days ago, there was a flash-in-the-pan controversy over Google "forking" Apple's open-source programming language Swift. After a few minutes of speculation over whether Google was going to make its own special flavor of the language for its own purposes, Swift's creator Chris Lattner (who now works at Google) helpfully clarified the situation:
  • Brilliant Jerks in Engineering
    This are numerous articles and opinions on the topic, including Brilliant Jerks Cost More Than They Are Worth, and It's Better to Avoid a Toxic Employee than Hire a Superstar. My colleague Justin Becker is also giving a talk at QConSF 2017 on the topic: Am I a Brilliant Jerk?. It may help to clarify that "brilliant jerk" can mean different things to different people. To illustrate, I'll describe two types of brilliant jerks: the selfless and the selfish, and their behavior in detail. I'll then describe the damage caused by these jerks, and ways to deal with them. The following are fictional characters. These are not two actual engineers, but are collections of related traits to help examine this behavior beyond the simple "no asshole rule." These are engineers who by default act like jerks, not engineers who sometimes act that way.
  • [Older] The missing career path for software developers
    You started hacking on technology thrilled with every stroke of the key, making discoveries with every commit. You went about solving problems, finding new challenges. You were happy for a while, until you hit a plateau. There was a choice to be made. Continue solving the same problems or start managing others. You tried it out, and hated it. Longing to focus on technology, not people, you turned to your open source project. When it became successful, you became an open source maintainer but ended up overwhelmed and burned out. Hoping to get back to doing work that fascinates you, you went work for yourself. Lacking experience running a business, you're crushed with all the decisions you need to make. You’re nearing burnout — again. It feels like you’re on a hamster wheel.

Mastodon is Free Software, But It Does Not Respect Free Speech
