Five tips for improving Linux security

What’s that you say? You don’t need to do anything about security on your Linux box because it’s Linux? Think again. Linux is an operating system that begs to be online, so it wants to be secure. Sure it’s fairly secure out of the box, but NO operating system is 100% secure if it’s, well, turned on. Here are five crucial Linux security tips.

1: Take advantage of the keyring

To many, this is an annoyance. You log in to your machine, your machine requests a connection to a network (or LDAP server, etc.), and you have to enter your keyring password. The temptation is to disable this feature by giving it an empty password and dismissing the warning that you’ll be transmitting unencrypted information (including passwords). This is not a good idea. Although you might think it a hassle, this feature/functionality is there for a reason — to encrypt sensitive passwords when they are sent over the wire.

2: Enforce user password update

Add-on board expands i.MX6 UL SBC

MYIR released an add-on board for its Linux-driven, i.MX6 UL-based MYS-6ULX SBC that adds a second LAN port, plus CAN, RS485, camera, audio, and RTC. In April, MYIR released a Linux-powered MYS-6ULX SBC, which was notable for being available in two different versions using NXP’s low power, Cortex-A7 i.MX6 UltraLite (UL) or the more affordable, and almost identical i.MX6 ULL SoC. Now, MYIR has released an “MYB-6ULX Expansion Board” designed to stack onto either model. The $21.20 accessory adds a second 10/100 Ethernet port to the MYS-6ULX, as well as new CAN, RS485, audio, micro-USB, RTC, and camera functions. Read more

Finding the Mainframers of the Future Through Open Source Ecosystem Development

Speak the word “mainframe” to many millennial techies, and the first things that likely come to mind are in the form of grainy sepia photos of floor-to-ceiling, wall-to-wall computers with big spinning tapes. But that’s far from the reality of the modern mainframe. Imagine instead up to 240 10-core, 5.2ghz processors, 32TB of RAIM (redundant array of independent memory), hardware-based encryption, and fully hot-swappable hardware components. Those are the specs of the newly released IBM z14 – a single machine that could replace the computing resources of an average corporate data center with room to spare. Read more

Linux Foundation’s Open Source Networking Days and KDE's Randa

  • Introducing The Linux Foundation’s Open Source Networking Days
    One of my primary goals at The Linux Foundation is to foster innovation across the entire open source networking ecosystem. This involves coordinating across multiple open source projects and initiatives and identifying key areas for collaboration to create an open source networking stack. We are working across the entire ecosystem with industry-leading partners — from developers to service providers to vendors — to unify various open source components and create solutions that will accelerate network transformation. As part of this journey, I am pleased to introduce Open Source Networking Days (OSN Days), a series of free events that are hosted and organized by local user groups and The Linux Foundation members, with support from our projects, including DPDK, FD.io, ONAP, OpenDaylight, OPNFV, PNDA, and others.
  • Randa news, release update
    Last week, from wednesday to saturday I attended KDE’s annual Randa sprint organized by wonderful people. This was an occasion to work fulltime on Kdenlive.
