This month's Topics - Sensu and ZFS

Thom Duran - Sensu

Abstract: Sensu is an open source project that makes a custom monitoring system easy to configure. The Sensu stack consists of RabbitMQ, Redis, and Sensu itself. While Sensu is easy to setup and configure, high availability and scalability is still a concern. We will discuss the archticture that allows for high availability that easily scales as needed.

Bio: Thom Duran is a Phoenix native who has worked at GoDaddy for 7 years in multiple roles. He currently works as a Site Reliability/Zero Touch Engineer focusing on monitoring and automation.

Kevin Bowling - ZFS

Abstract: OpenZFS is a state of the art cross-platform filesystem for Linux, FreeBSD,
Illumos, and Mac OS X.  This talk will detail how it differs from
traditional UNIX file systems, the current status for the different
supported operating systems, an introduction to the userland control
programs, an overview of hardware considerations for system builders, and a
brief look at the internal structure.

Bio: Kevin is a systems developer at Limelight Networks and has experience with a wide range of UNIX implementations. Current interests include OS build and release engineering for large scale clusters like Limelight's FreeBSD footprint.
Topic: BSD panel featuring FreeBSD and OpenBSD

Panellists: Kevin Bowling, Darrin Chandler

Bio: Kevin is a systems developer at Limelight Networks and has experience with a wide range of UNIX implementations. Current interests include OS build and release engineering for large scale clusters like Limelight's FreeBSD footprint.

Bio: Darrin has been developing software for more than 25 years, most recently for the Lunar Reconnaissance Orbiter NASA mission, and is a long time user of OpenBSD and previously FreeBSD.

PLUG's August topics will be CLI packet forensics and Blender.

Topic: CLI packet forensics

As Information Security evolves, more tools are being released that allow us investigate incidents quicker and easier, conversely making many analyst lazier. The sacrifice we have made to this idol of convenience is increasing layers of abstraction from the 'truth' of raw data, placing trust in tools we did not write using methods we do not know. While these high level tools are good to have, the ability to use simple, low-level tools is essential for security professionals.

This workshop will focus on using 'low-level' tools for network forensics. We will be using Wireshark's CLI tools, tcpdump, and Linux CLI tools to look at PCAPs to find and extract interesting information. A laptop with an Ubuntu VM is recommended, as all the tools we will be using should be 'apt-get'able. Please install these tools before the workshop if at all possible.

Topic: Basic Modelling Tools in Blender 3D
 
Basic introduction to  Blender, focusing on the modelling tools. The basic geometric techniques (extrusion, knife cut, radial cutting tool etc) along with the sculpting tools (and the dynamic topology sculpting tools). Then an example of how to use the boolean tools to create geometry as well. Finally a quick demonstration of what "UV unwrapping" is about, and how to utilize it.
 
BIO:
Phil Waclawski has been teaching Linux at Mesa Community college for about 15 years. He also teaches Web Development, Javascript, PHP, MySQL and basic Linux internet server set up. He has done summer camps for high school students teaching them the basics of 3D modelling with Blender. He first started in Linux with version 1.0 on Slackware back in 1994, and has been hooked every since.
 
Various hobbies include leatherwork, blacksmithing, wood work , archery (belongs to the Society for Creative Anachronism) and lately SCUBA. Was happily surprised to find out the Linux based software for his dive computer was written partly by Linus.

Title: Simple Techniques for Online Password Security

Abstract: Heartbleed likely exposed passwords everywhere. 60% of web sites might have been susceptable to the recent security vulnerability that was all over the news. Since Heartbleed eaves no trace, we do not know how much it was exploited.

Once they have your credentials, crackers need only minutes to try them at millions of sites. Avoid that domino effect by using simple, effective techniques to make sure information from one web site can't be used to compromise your account on another.

Using the same email address and password across multiple sites means that one break in can be leveraged to access your other accounts. Use different information for *every* site. No need for you to memorize a bunch of passwords or other information. Let a password manager such as KeePass, KeePassDroid or KeePassX handle that for you.

Also keep track of other data such as PINs, security question answers, the shoe size you gave them and other data you need to keep secure.

Learn about two factor authentication.
