The Awesome Program You Never Should Use

I've been hesitating for a couple months about whether to mention sshpass. Conceptually, it's a horrible, horrible program. It basically allows you to enter an SSH user name and password on the command line, so you can create a connection without any interaction. A far better way to accomplish that is with public/private keypairs. more>>

Obsession with Big Data has gotten out of hand. Here's how. more>>

Encrypt Your Dog (Mutt and GPG)

I have been focusing a lot on security and privacy issues in this year's columns so far, but I realize some of you may expect a different kind of topic from me (or maybe are just tired of all this security talk). Well, you are in luck. more>>

Security Hardening with Ansible

Ansible is an open-source automation tool developed and released by Michael DeHaan and others in 2012. DeHaan calls it a "general-purpose automation pipeline" (see Resources for a link to the article "Ansible's Architecture: Beyond Configuration Management"). more>>

Linux Security Threats on the Rise

Every year, heck...every month, Linux is adopted by more companies and organizations as an important if not primary component of their enterprise platform. And the more serious the hardware platform, the more likely it is to be running Linux. 60% of servers, 70% of Web servers and 95% of all supercomputers are Linux-based! more>>

Tails above the Rest, Part III

In my first two columns in this series, I gave an overview of Tails, including how to get the distribution securely, and once you have it, how to use some of the basic tools. more>>

Tails above the Rest, Part II

Now that you have Tails installed, let's start using it. more>>

Tails above the Rest: the Installation

A few columns ago, I started a series aimed at helping everyone improve their privacy and security on the Internet. The first column in this series was an updated version of a Tor column I wrote a few years ago. more>>

Non-Linux FOSS: My Portable Windows Lab

Portable apps aren't anything new. There are variations of "single executable apps" for most platforms, and some people swear by keeping their own applications with them for use when away from home. I don't usually do that, as most of what I do is on-line, but there is one exception: security. more>>

The Growing Role of UEFI Secure Boot in Linux Distributions

With the increasing prevalence of open-source implementations and the expansion of personal computing device usage to include mobile and non-PC devices as well as traditional desktops and laptops, combating attacks and security obstacles against malware is a growing priority for a broad community of vendors, developers and end users. more>>

Two-Factor Authentication System for Apache and SSH

If you run a publicly accessible Web server for your own use (and let's face it, if you're reading Linux Journal, there's a very good chance you do), how do you go about limiting the risk of someone accessing your site and doing bad things? How about SSH, an even bigger concern? more>>

Quantum Cryptography

Classical cryptography provides security based on unproven mathematical assumptions and depends on the technology available to an eavesdropper. But, these things might not be enough in the near future to guarantee cyber security. We need something that provides unconditional security. We need quantum cryptography. more>>

Encrypting Your Cat Photos

The truth is, I really don't have anything on my hard drive that I would be upset over someone seeing. I have some cat photos. I have a few text files with ideas for future books and/or short stories, and a couple half-written starts to NaNoWriMo novels. It would be easy to say that there's no point encrypting my hard drive, because I have nothing to hide. more>>

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
