January Meeting: Everything We Know About CyberSecurity is Wrong (Ryan Byrd)

Date: Tuesday, January 17th
Time: 7:00pm
Location: UVU Business Resource Center

The exploits and security breaches which are technically feasible and the ones that actually occur in the wild are two very different things. There are two common, bad assumptions: one, that people choose random passwords and two, that passwords are broken with dumb brute force. Neither of those assumptions are correct. Brute force attacks are never used on passwords of longer than six characters because it takes too long. So instead, hackers use word list attacks that combine list of words gathered from hacked passwords, Wikipedia, the Gutenberg Project and YouTube comments and then combine those words in unique ways (https://hashcat.net/wiki/doku.php?id=oclhashcat has over 5100 rules to do this). This so-called intelligent brute force reduces the candidate key space and makes attacks possible on 55 character or longer passwords.

Ryan is a computer engineer working at the base of the Rocky Mountains. Sometimes he solves hard problems, builds embedded devices, creates web applications and automates processes for good people. Sometimes he just keeps bees. He’s very busy and important.

September Meeting: Kerberos Protocol (Tyler Johnson)

Date: Tuesday, September 20th
Time: 7:00pm
Location: UVU Business Resource Center

PLEASE NOTE THE NEW TIME! We’re going to start meeting at 7:00pm instead of 7:30pm

Tyler Johnson will be explaining the kerberos protocol and demonstrating it’s use in various environments. Kerberos is a computer network authentication protocol which works on the basis of tickets to allow nodes communicating over a non-secure network to prove their identity to one another in a secure manner. Used in many different Operating Systems and services, it is aimed at a client-server model and provides mutual authentication — both user and server verifiy each other’s identity. Kerberos builds on symmetric key cryptography and protects against eavesdropping and replay attacks.

The demonstration will mainly take place in a debian-based environment, which is recommended if you want to follow along.

August Meeting: Low Cost, Large Scale Open-source Projects (James Simister)

Date: Tuesday, August 16th
Time: 7:00pm
Location: UVU Business Resource Center

PLEASE NOTE THE NEW TIME! We’re going to start meeting at 7:00pm instead of 7:30pm

GitHub is a great solution for many open-source projects, but what if it isn’t right for your project? If you need more control over your project or want to run your own systems, what are some good choices?The OpenDOF Project (https://opendof.org) found itself in that situation last year when it was formed. This talk presents the solutions that we identified and integrated in order to provide a web presence, source control, defect tracking and continuous integration. The talk will also briefly cover an open-source project that we created for large-scale automated testing.

We will share the tools chosen and costs that we incur, as well as how we deal with issues like download support at large scale.

June Meeting: daplie-tools domain management (Josh Mudge)

Date: Tuesday, June 21st
Time: 7:30pm
Location: UVU Business Resource Center

Josh Mudge will be demonstrating how to use daplie-tools: https://github.com/daplie/daplie-tools. It is open source (MPLv2) CLI software you can use it to purchase or transfer domains and easily manage DNS, DDNS (Dynamic DNS) and MDDNS (Mirrored Dynamic DNS). He will also be demonstrating how to “purchase” a free* daplie.me subdomain in daplie-tools.

Please bring your own computer with node.js and/or daplie-tools installed to try it out, you can easily install them here: https://github.com/daplie/daplie-tools#install*Free for 6 months then $2/Year, which is pretty reasonable as it shouldn’t be blocked by government, business or school firewalls. See: https://github.com/daplie/daplie-tools/#why-do-we-require-a-credit-card

Just go in the front doors, and follow the signs. We’re usually in a conference in the back of the main floor. There will be pizza provided by TekSystems.

April Meeting: Using VXLAN to network virtual machines, containers and other fun things

Date: Tuesday, April 19th
Time: 7:30pm
Location: UVU Business Resource Center

John Nielsen will present about VXLAN, a relatively new protocol for transporting a large number of virtual Ethernets over any IP network. It draws from and improves upon both VLANs and point-to-point network tunnels. Once a “virtual tunnel end point” is configured for one or more VXLANs it discovers the other end points and hosts within each network automatically. This presentation will introduce VXLAN in greater detail, compare it to VLANs and traditional L2-over-L3 tunnels, and describe and demonstrate several use cases for VXLAN on Linux and BSD including containers, virtual machines, and wireless bridging.
