This month Phil Waclawski will give us an introduction to Krita and Ed Nicholson will explain DNSSEC and NTPsec

Phil Waclawski: Krita Basics: Tools, Layers, Coloring etc

Krita is a powerful painting program, designed for graphic designers and general artists. I will introduce the basic features it provides, along with some special filters, including G'mic. I will however not be able to demonstrate any artistic skills :)

Ed Nicholson: DNSSEC DANE & NTPsec - Trust but Verify
DNSSEC DANE and NTPsec - The basic infrastructure of the Internet hasn't seen such significant improvement since Jon Postel's contributions to the original DNS RFCs. DNSSEC is operational authentication of information served by authoritative DNS servers. This is the dawn of the believable Internet. An important consequence has been the emergence of DANE or DNS-based Authentication of Named Entities. And that adds confidentiality to believability. Even as Internet naming gains this new robustness, similar efforts are improving our access to time services with the NTPsec project. While not all Internet infrastructure has left the era of blind trust, the names and times we depend on are now things we can verify. This presentation is about consuming and deploying DNSSEC DANE and NTPsec services.

About Ed:
Ed has been involved with Free Software for some time. His interests are in how people, organizations and populations use, create and experience information. He enjoys The Prescott National Forest as his "office" and The Valley of The Sun as a home away from home. Personal systems run either Fedora, Project Atomic, Android or OpenBSD.

 

PLUG is hosting a CryptoParty!

Show up on Thursday May 11th to get help securing your mobile and desktop electronics.

A CryptoParty is a global, decentralized, grass-root movement to help people protect their privacy.

The Phoenix Linux Users Group (PLUG) will have labs to help you setup things like secure messaging with Signal, VPN, TOR, a password manager and multi-factor authentication.

A CryptoParty relies on two resources. 1) people with the knowledge and desire to lead a lab; 2) people who want to take the lab and improve their security.

This month we will have a two presentations.  Phil Waclawski will present "Using Hierarchical Data in MySQL, Trees vs Nests" and Ed Nicholson will present "Securing a SSH Bastion host with PrivacyIDEA and U2F"

Phil Waclawski: Using Hierarchical Data in MySQL, Trees vs Nests

Real world data is often made of hierarchical relationships, or "trees".
Representing that data in a Relational Database starts to get complicated as soon as you have more than two levels in your "Tree".
There are many strategies for handling such data, and I will cover examples of at least two of them (adjacency list and nested sets) and possibly more.

If you have access to a mysql instance, you can create the test tables and follow along, or get the code later.

Ed Nicholson: Securing a SSH Bastion host with PrivacyIDEA and U2F

Bastion Servers are an important tool for access control to your other
systems. PrivacyIDEA is a credential management system that can add
many types of authentication to your Jump Server, for example U2F.
FIDO Universal 2nd Factor Keys are a convenient standard implemented
by many to improve security. PrivacyIDEA is a great example of how
easy adding important levels of security to your systems can be.

About Ed:
Ed has been involved with Free Software for some time, and is most
interested in how people, organizations and populations use, create and
experience information. Recently, Ed is enjoying The Prescott National Forest
as his "personal office" and The Valley of The Sun as a home away from home.
Personal systems run either Fedora, Project Atomic, Android or OpenBSD.

We have two presentations for February, from Yael Grauer and der.hans.

Yael will discuss hacker-show Mr. Robot and what it gets right about tech. Hans will cover etckeeper, a tool for tracking configuration changes.

For more info, Meeting time and location see:
http://phxlinux.org/index.php/meetings/14-east-valley-meeting.html


Yael Grauer: What Mr. Robot Gets Right

Description: Not only does Mr. Robot set the bar for dystopian hacker suspense thrillers, it’s also a great hacking show that’s true to the culture and portrays technology authentically.

In this presentation, Yael will discuss what Mr. Robot gets right... and the mostly free, mostly open source programs used by the characters on the show.

Biography: Yael is a freelance tech reporter covering online privacy and security, mass surveillance, and digital freedom. She has written for WIRED, Ars Technica, Slate, Motherboard, the Intercept, Forbes Tech, and more. She also co-hosts Monday Morning Dumpster Dive, a podcast on Friday news dumps that also airs on KJZZ.

For fun, Yael enjoys hiking, gardening, Brazilian jiu-jitsu, and spending time with her husband and their puppy.


der.hans: etckeeper - revision control for /etc/

Description: Ever debug a service problem for hours just to discover it was a new typo in a configuration file? Ever have someone (maybe you) bork a conf file and not realize it for days? Put /etc/ into version control, then track what changes and when.

etckeeper tracks changes in /etc/ with version control. It ties into package management systems for automagic checkins after updates.  It also records important metadata such as permissions and ownership that version control systems (VCS) usually do not track.

Use the VCS you know and let etckeeper help you with some of the oddities found in /etc/.

An imporatant feature is detecting inadvertant changes or tracking what someone (maybe even you) did late at night or early in the morning. By tracking changes, you can document them, replicate them elsewhere or even back them out.

Biography: der.hans is a Free Software, technology and entrepreneurial veteran. He is a repeat author for the Linux Journal with his article about online privacy and security using a password manager as the cover article for the January 2017 issue.

He is chairman of the Phoenix Linux User Group (PLUG), BoF organizer for the Southern California Linux Expo (SCaLE) and founder of the Free Software Stammtisch.

He presents regularly at large community-led conferences (SCaLE, SeaGL, LFNW) and many local groups.
We have two presentations on security this month, from Aaron Jones and der.hans. Aaron will review a variety of security incidents from 2016 while Hans will cover security and privacy practices we can take and how a password manager makes it easy.

See our meeting page for time and location

Aaron Jones - 2016 - A Year End Review!

Description: We are going to look back at 2016 and some of the gnarly security hacks that took place. We will discuss the FBI database leak, Podesta emails, DNC, and a super massive bank hack foiled by bad spelling.

Bio: Aaron is a frequent flyer at PLUG who likes the command line. He spends his time doing computer stuff and even went to school for computers at some point in his life. He uses Linux, I3, and Bash.

der.hans - Online Privacy, Security and Password Management

Description: Take control of your online security and privacy. Continuing breaches at high-profile sites prove that you can't rely on cloud services to protect your accounts.

This updated presentation is the basis my January 2017 Linux Journal cover article.

Password managers such as KeePassX make it easy to use different, strong passwords and usernames for each site. They also enable other good security practices. Take charge of your personal online security.

Also covers practices that can effectively keep your online accounts
seperate from each other so that a security breach at one company doesn't
expose your other accounts. Avoid the domino effect.
