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.
Join the Phoenix Linux Users Group at their Security Session to learn about real world exploits used in the wild to gain unauthorized access to computers. We will be discussing Brute Force Attacks, Man-In-The-Middle attacks (DNS hijacking), Social Engineering, and Web Application Exploits targeting popular CMS like WordPress. This two hour meeting will focus on providing simplified and easy to follow explanations of the methods used to attack your servers and how you can better prepare yourself to mitigate the risks.
