Create an encrypted disk image in GNU/Linux

Filed under
Security
HowTos

In my previous article about creating a "mountable" disk image in GNU/Linux, I explained how to create a file that effectively mimics the functionality of a disk: I explained how to create a file which will then be used, in turn, to contain directories and files. In this article I will explain how to make the next natural step: encrypt that file.

Emergency Security Band-Aids with Systemtap

Filed under
Red Hat
Security

Software security vulnerabilities are a fact of life. So is the subsequent publicity, package updates, and suffering service restarts. Administrators are used to it, and users bear it, and it’s a default and traditional method.

On the other hand, in some circumstances the update & restart methods are unacceptable, leading to the development of online fix facilities like kpatch, where code may be surgically replaced in a running system. There is plenty of potential in these systems, but they are still at an early stage of deployment.

Docker Delivers Security Configuration Checking Tool

Filed under
Server
Security

The Docker Bench for Security script is packaged as a Docker container to make it easier to run and test. One of the CIS Benchmark's recommendations is to limit container privileges to only what is needed to run. Somewhat ironically, the Docker Bench for Security script is a very high-privilege container that has broad access to host resources—usually something a container should not be able to do. That said, as a security testing tool, the container does need the broad access to validate host configuration for container deployment properly.

Is your open source security software less secure?

Filed under
OSS
Security

"Your secure software is open source; doesn't that make it less secure?"

This is a recurring question that we get at Benetech about Martus, our free, strongly encrypted tool for secure collection and management of sensitive information built and provided by the Benetech Human Rights Program. It's an important question for us and for all of our peers developing secure software in today's post-Snowden environment of fear and worry about surveillance. We strongly believe not only that open source is compatible with digital security, but that it's also essential for it.

Leftovers: Gaming

KDE and Akademy

  • KDE Has Created Shashlik, A Way To Install Android Apps On Linux
    As you may know, KDE has created Shashlik, an emulator that permits the installation of Android apps on Linux systems. While Android is still Linux because they share the Linux kernel, Google’s OS has its own libraries and services while Linux uses the libraries and services brought by GNU.
  • Passing the Torch
    I hereby want to announce an open call to find a new maintainer for KDE’s speech recognition efforts.
  • Kubuntu Paddleboard Club
  • Akademy 2015 & Kate
    I didn’t do that much work on Kate, I mostly did small bugfixes for the applications bundled with the KDE Applications releases regarding their HiDPI support, finally no Konsole that can’t redraw correctly on scrolling on a HiDPI screen with scaling activated!
  • It’s the final countdown
  • Akademy 2015 coming to an end
    During the BoF days from Monday to Thursday, a great many tiny videos were shot of many of the attendees by Dan Leinir Turthra Jensen. These have been edited and cut up and turned into a video explaining, very shortly, what KDE really is. Being a community of people contributing to the development of software, the conclusion is straight forward. See the unsurprising conclusion in the video entitled What is KDE? (webm, mp4, vimeo), created as a tribute to the KDE community and all the amazing people in it.

  • Android for Work Gets Support from Major U.S. Carriers
    Earlier this year, we were reporting on one of the biggest security holes ever affecting Android. In fact, PaloAlto networks had found that that security breach affected almost 50 percent of Android devices, making them vulnerable to an attack that can swap out a user's pre-installed app with malware that can round up sensitive data. The fact is, concerns about security and other issues have made some enterprises wary of letting users standardize on Android devices.
  • Android Studio 1.3 (Android IDE Developed By Google) Has Been Released
  • OnePlus 2 Review Roundup: Solid Android Smartphone And Fantastic Tag Price
    The OnePlus 2 will not become available in the U.S. and Europe until Aug. 11, but the first reviews of the Chinese startup's second flagship smartphone are already in, and the verdict is a resounding thumbs up from most people who were lucky enough to be given a preview build. When it comes to the OnePlus 2's design, reviewers agree that the device has a solid, comfortable build thanks to the textured sandstone panel on the back and the slight convex shape that curves right into the hands, while still evoking that premium feel with the aluminum frame holding up the device.
