How to secure your Raspberry Pi

Filed under

The Raspberry Pi and many other inexpensive computer boards like it have become part of the "Internet of Things" or IoT revolution. Internet-connected computing devices have emerged beyond traditional servers, desktops, laptops, and mobile devices. Now your TV, DVR (digital video recorder), thermostat, refrigerator, Internet radio, Raspberry Pi, and other devices are on the network too.

IoT has been huge for experimentation and innovation. But as projects get rushed to completion, there have been severe consequences for ignoring security. And this applies both to commercial products and hobby projects. I'll talk about the Raspberry Pi specifically in this article, so this post is oriented more toward do-it-yourself projects.

Security: Updates, Synopsys/Black Duck FUD, and Software Security Over Convenience

  • Security updates for Tuesday
  • With Much of the Data Center Stack Open Source, Security is a Special Challenge [Ed: Black attacking FOSS again in order to sell its proprietary products; does proprietary software have no security issues? Which cannot be fixed, either?]
  • Synopsys reveals its open-source rookies of the year [Ed: Anti-FOSS company Black Duck, which markets its proprietary software by attacking FOSS (it admitted being anti-GPL since inception, created by Microsoft employee), wants the public to think of it as a FOSS authority]
  • Software security over convenience
    Recently I got inspired (paranoid ?) by my boss who cares a lot about software security. Previously, I had almost the same password on all the websites I used, I had them synced to google servers (Chrome user previously), but once I started taking software security seriously, I knew the biggest mistake I was making was to have a single password everywhere, so I went one step forward and set randomly generated passwords on all online accounts and stored them in a keystore.

MIPI-CSI camera kit runs Linux on Apollo Lake

Congatec’s rugged, Linux-driven “Conga-CAM-KIT/MIPI” camera kit combines its Intel Apollo Lake based Conga-PA5 SBC with a MIPI-CSI 2 camera from Leopard Imaging and other components. Congatec announced a Conga-CAM-KIT/MIPI camera kit, also referred to as the MIPI-CSI 2 Smart Camera Kit. The kit runs a Yocto Project based Linux distribution on Congatec’s Conga-PA5, a Pico-ITX SBC with Intel’s Apollo Lake Atom, Pentium, and Celeron SoCs. Also included is a MIPI-CSI 2 camera (LI-AR023Z-YUV-MIP) from Leopard Imaging based on ON Semiconductor’s AR0237 HD sensor. Extended temperature ranges are supported. Read more
