«Now, for the best, start another terminal window, and switch to root (e.g. using su, or sudo). Notice how the xinput running as user is able to sniff all your keystrokes, including root password (for su), and then all the keystrokes you enter in your root session.» - http://theinvisiblethings.blogspot.fr/2011...
«The X server architecture, designed long time ago by some happy hippies who just thought all the p̶e̶o̶p̶l̶e̶ apps are good and non-malicious, simply allows any GUI application to control any other one. No bugs, no exploits, no tricks, are required. This is all by design. One application can sniff or inject keystrokes to another one, can take snapshots of the screen occupied by windows belonging to another one, etc.» - 9000 from Bookmarklet

Linus Torvalds suspends key Linux developer - Network World - http://www.networkworld.com/news...
"An argument between developers of some of the most basic parts of Linux turned heated this week, resulting in a prominent Red Hat employee and code contributor being banned from working on the Linux kernel. Kay Sievers, a well-known open-source software engineer, is a key developer of systemd, a system management framework for Linux-based operating systems. Systemd is currently used by several prominent Linux distributions, including two of the most prominent enterprise distros, Red Hat and SUSE. It was recently announced that Ubuntu would adopt systemd in future versions as well." - imabonehead from Bookmarklet

""kGraft is intended to be merged into the upstream Linux kernel and to become a living open-source project," Pavlik said. "It builds on and improves existing Linux infrastructure to fit seamlessly into the Linux kernel." Pavlik noted that a key difference between Ksplice and kGraft is the upstream kernel approach. Pavlik noted that Ksplice tried – and failed – to get upstream acceptance in 2008, primarily because of the complexity of the changes required." - imabonehead from Bookmarklet

Introducing kpatch: Dynamic Kernel Patching | Red Hat Enterprise Linux Blog - http://rhelblog.redhat.com/2014...
"In upstream development news, the kernel team here at Red Hat has been working on a dynamic kernel patching project called kpatch for several months. At long last, the project has reached a point where we feel it’s ready for a wider audience and are very excited to announce that we’ve released the kpatch code under GPLv2. kpatch allows you to patch a Linux kernel without rebooting or restarting any processes. This enables sysadmins to apply critical security patches to the kernel immediately, without having to wait for long-running tasks to complete, users to log off, or scheduled reboot windows. It gives more control over uptime without sacrificing security or stability." - imabonehead from Bookmarklet

"This film "The UNIX System: Making Computers More Productive", is one of two that Bell Labs made in 1982 about UNIX's significance, impact and usability. Even 10 years after its first installation, it's still an introduction to the system. The other film, "The UNIX System: Making Computers Easier to Use", is roughly the same, only a little shorter. The former film was geared towards software developers and computer science students, the latter towards programmers specifically. The film contains interviews with primary developers Ritchie, Thompson, Brian Kernighan, and many others." - imabonehead from Bookmarklet

HonSSH - A high interaction honeypot solution for Linux based systems - BruteForce Lab's Blog
"Honeypots have been hard to deploy. Many techniques required you to install software on the honeypots themselves that send information about what is happening on the system back to a collector/sensor. This strategy has worked most of the times, but the reporting software have in some cases rendered the honeypots unusable and the attackers have sometimes been able to detect it." - imabonehead from Bookmarklet
"Late summer of 2013, I came across a Python project that – while far from being a “silver bullet” – had great potential and worked amazingly well. It was easy to deploy and configure and solved a lot of issues with the de facto way we deploy honeypots. The project is called HonSSH.

It has built-in web server that runs as a web-based SSH client on a specified port and prompt you a web terminal emulator to access and control your Linux Server SSH Shell remotely using any AJAX/JavaScript and CSS enabled browsers without the need of any additional browser plugins such as FireSSH." - imabonehead from Bookmarklet

It is tested with all mentioned webservers, NGINX 1.1.19, Lighttpd 1.4.28 and Apache 2.2.22 on Ubuntu 12.04, Debian 6 & 7 and CentOS 6.It should work on other distro's however, these are just reference values." - imabonehead from Bookmarklet

But by last year Microsoft itself had become one of the top 20 corporate contributors to Linux, writing code to make sure its products work well with the ubiquitous software -- a sign of just how thoroughly Linux has conquered the enterprise." - imabonehead from Bookmarklet

ISC Diary | How To: Setting Up Google's Two-Factor Authentication In Linux - https://isc.sans.edu/diary...
"We can already use two-step authentication in GMail with the Google Authenticator Android app. The idea is creating a secret key shared between the service and the Android app, so every 30 seconds we get a randomly generated token on Android that must be provided to login in addition to the password. That token is only valid in that 30s time frame. Since this provides a nice second security layer to our logins, why don't take advantage of it also in our Linux box? We'll need two things to get started..." - imabonehead from Bookmarklet

Malware and Antivirus Systems for Linux | Linux.org - http://www.linux.org/threads...
"All computer systems can suffer from malware and viruses, including Linux. Thankfully, very few viruses exist for Linux, so users typically do not install antivirus software. It is still recommended that Linux users have antivirus software installed on Linux systems that are on a network or that have files being transfered to the device. Some users may argue that antivirus software uses up too much resources. Thankfully, low-footprint software exists for Linux. To better understand antivirus programs, it may be beneficial to understand malware itself." - imabonehead from Bookmarklet
