"No system is complete without some form of security. There must be a mechanism available to protect files from unauthorized viewing or modification. The Linux system follows the Unix method of file permissions, allowing individual users and groups access to files based on a set of security settings for each file and directory. In this Classroom we will discusses linux security via /etc/passwd & /etc/shadow file and how to manage user's Accounts"

The blurb is a bit misleading. This is a project that's been under way since last year; what's new is that they're moving under the Linux Foundation umbrella for various non-technical suoport purposes. By sometime this summer, encrypting web site data and broadcasting it over https is  slated to become a two-click process. Or on the linux command line: $ sudo apt-get install lets-encrypt $ lets-encrypt example.com This is a project that grew out of public disgust with NSA surveillance, designed to flood the NSA (and other bad actors) with so much encrypted data that they will be able to decrypt only a tiny fraction (decryption without the decryption key takes gobs of computer cycles).  The other half of the solution is already available, the HTTPS Everywhere extension for the Chrome, FIrefox, and Opera web browsers by the Electronic Frontier Foundation and the TOR Project that translates your every request for a http address into an effort to connect to an https address preferentially before establishing an http connection if https is not available. HTTPS Everywhere is fast and does not noticeably add to your page loading time. If you'd like to effortlessly imoprove your online security and help burden NSA, install HTTPS Everywhere.

"Way back in kernel 2.6, a new security system was introduced to provide a mechanism for supporting access control security policies. This system was Security Enhanced Linux (SELinux) and was introduced by the National Security Administration (NSA) to incorporate a strong Mandatory Access Control architecture into the subsystems of the Linux kernel."

"Posted on July 18, 2014 by Adrien Brochard Leave a comment If you enjoy music streaming and originally-created sounds, you cannot have missed SoundCloud. Based in Germany, this cloud streaming service is now famous and well-established for any music adventurer. And naturally, as a Linux enthusiast, you might wonder how to join your passion for Linux with your love for music. As a solution, I advise you to check out Soundcloud2000, a command line client for SoundCloud born out of the Music Hack Day Stockholm '13."

"In this article we will explain what TCP wrappers are and how to configure them to restrict access to network services running on a Linux server. Before we start, however, we must clarify that the use of TCP wrappers does not eliminate the need for a properly configured firewall."

"While Google Drive is no doubt one of the most popular (if not the most popular) cloud storage services available today, what's really sad is that there is no official Drive client available for Linux. But that doesn't mean there are no alternatives - in fact the awesome Linux/open-source community has developed several unofficial Google Drive clients, some of which we've already discussed here at HowtoForge."

"Wouldn't it be fantastic if there was a way to access a remote Linux server directly from the web browser? Luckily for us all, there is a tool called Wetty (Web + tty) that allows us to do just that - without the need to switch programs and all from the same web browser window."

"Most of the time, having a password protected user is all you need to keep your files private and protected from prying eyes. There are those few times when you need to allow access to your account to another person, sometimes there are folders or files you would like to keep away from being accessed. Now we can password protect folder with several handy tools. In the Windows world, these tools are quite easily available for Windows but today we will look at a few options available for the Linux user."

"linuxmessenger app is a "Facebook-like" client for Linux desktop was written in Python language. It allows you to login to your Facebook account right from the command line without installing it on your system and have chat with your loved ones with much a like a Facebook interface. If you want, you can install it as a desktop client. This application has some built-in features like desktop notifications, pop-up alert, friends request and chat sound (with On/Off options)."

[The GHOST vulnerability is a flaw in a vital part of every major Linux distro. It could, in theory, allow hackers to take control of computers without the need for a username or password.+

Great story that is at the center of a new cloud computing platform. I met David Flynn back when he was first demonstrating the Realmsys flash card. Extraordinary stuff. He was using the technology to open a secure Linux computing window on an operating Windows XP system. The card opened up a secure data socket, connecting to any Internet Server or Data Server, and running applications on that data - while running Windows and Windows apps in the background. Incredible mesh of Linux, streaming data, and legacy Windows apps. Everytime I find these tech pieces explaining Fusion-io though, I can't help but think that David Flynn is one of the most decent, kind and truly deserving of success people that I have ever met. excerpt: "Apple is spending mountains of money on a new breed of hardware device from a company called Fusion-io. As a public company, Fusion-io is required to disclose information about customers that account for an usually large portion of its revenue, and with its latest annual report, the Salt Lake City outfit reveals that in 2012, at least 25 percent of its revenue - $89.8 million - came from Apple. That's just one figure, from just one company. But it serves as a sign post, showing you where the modern data center is headed. 'There's now a blurring between the storage world and the memory world. People have been enlightened by Fusion-io.' - Gary Gentry Inside a data center like the one Apple operates in Maiden, North Carolina, you'll find thousands of computer servers. Fusion-io makes a slim card that slots inside these machines, and it's packed with hundreds of gigabytes of flash memory, the same stuff that holds all the software and the data on your smartphone. You can think of this card as a much-needed replacement for the good old-fashioned hard disk that typically sits inside a server. Much like a hard disk, it stores information. But it doesn't have any moving parts, which means it's generally more reliable. It c

"Postby weazy » Fri May 30, 2003 5:19 pm Methodology Simplicity The simplicity methodology seeks to increase security by reducing vulnerability. In the rest of this tutorial you will learn to: 1. Reduce network access to your machine using a firewall (we'll teach you how to build your own) 2. Decrease the number of priveleged programs. You help yourself by decreasing priveleged programs because you reduce the ways ppl can gain access 3. Tighten configuration of those priveleged programs you want to keep 4. Reduce number of paths to root, that is restrict access of non-priveleged users 5. Deploy intrusion detection by using file integrity checking "

"According to the U.S. Computer Emergency Readiness Team, "Passwords are a common form of authentication and are often the only barrier between a user and your personal information. There are several programs attackers can use to help guess or 'crack' passwords, but by choosing good passwords and keeping them confidential, you can make it more difficult for an unauthorized person to access your information.""

This month, it came in the form of an e-mail out of the blue from Jared Nielsen, one of two brothers (the other is J.R. Nielsen) who created The Hello World Program, "an educational web series making computer science fun and accessible to all". If it had been just that, I might not have been interested. "
