(Backdoor) Free BIOSes with Libreboot

When: Tue September 08, 2015 07:30 PM to 09:00 PM

Speaker: Kyle Rankin

Location: O'Reilly Media

While Linux users have spent a lot of time using free software on their computers, usually that stops at the operating system. Being able to view and modify your source code not only gives you more freedom, it gives you more security, in particular from back doors. What’s good for the OS is good for the BIOS, which malware hackers, Lenovo, and state-sponsored attackers have all used to persist their exploits.

In this talk Kyle will cover Libreboot, a completely free software distribution of the open source Coreboot BIOS and discuss the current state of hardware support for Libreboot and how to install it, including a brief description of how to turn a Raspberry Pi into a flashrom BIOS-flashing platform.

systemd roundtable

When: Tue June 09, 2015 07:30 PM to 09:00 PM

Speaker: Everyone

Location: O'Reilly Media

There is general concensus that systemd is an important topic but we haven’t found a speaker to specifically present on systemd so instead we’ll be doing a systemd roundtable. The format will be a friendly discussion about the pros and cons of systemd and its political and technical impact on distributions that have migrated to it for the enlightenment of all. I’ll bring the projector along just in case someone needs it.

OpenStack

When: Tue May 12, 2015 07:30 PM to 09:00 PM

Speaker: Allan Cecil

Location: O'Reilly Media

Description: OpenStack is a set of tools to create a “cloud” infrastructure similar to Amazon’s cloud services to manage virtual machines (called instances) across multiple Compute servers in a cluster managed by one or more Controllers. In this talk I’ll introduce the general concepts of what OpenStack can be used for in an approachable way. I’ll provide an overview OpenStack’s Controller and Compute node model, how instances work, block and image storage, and a general overview of bridged networking into virtual machines. The majority of the talk will be devoted to a live demo of spinning up instances with plenty of time for interactive Q and A.

Linux Bridging In a Virtualized Environment

When: Tue January 13, 2015 07:30 PM to 09:00 PM

Speaker: Robert Harker

Location: O'Reilly Media

Linux bridging is one of the seven mysteries of Linux. What is the br0 device and how does it use the NIC? What is virbr0? The answers to these and many other questions will be answered including how virtual instance use bridges and how they interact with the host’s IPtables. The goal of this talk is to give the Linux Sysadmin the understanding needed to configure, use and trouble-shoot Linux bridges.

Robert Harker is a [Linux|UNIX] greybeard sysadmin and one of the first Sun sysadmins. His interests include OS/application configuration management of scaling of server farms with a particular interest in verification of deployments: “How do you know it is correct and running?”

Anatomy of an Arbitrary Code Execution Exploit

When: Tue December 09, 2014 07:30 PM to 09:00 PM

Speaker: Allan Cecil

Location: O'Reilly Media

Allan writes,

This talk is all about dissecting exactly what happens when a program stops doing what the designers designed it to do and starts doing what an attacker (or in this case, the presenter) wants it to do. I’ll cover using a virtual machine environment of a simple system under Linux to step through all phases of an arbitrary code execution (ACE) exploit, including corrupting a data structure, out-of-bounds memory manipulation, pointer manipulation, and ultimately execution of arbitrary code. I’ll be demonstrating memory viewer and disassembly tools to show the exact instructions being processed as they happen.

The simple system in question? A Zilog Z80 processor, running inside of a Super Game Boy. Come for the dissection, stay for some entertaining abuse of a live SNES console. This will largely be a no slides, full demo presentation and should have something of interest for everyone. See you there!

Secure Server Deployments in Hostile Territory

When: Tue November 11, 2014 07:30 PM to 09:00 PM

Speaker: Kyle Rankin

Location: O'Reilly Media

It’s easy to secure your servers when they are in the safe confines of your own data center, but deploying servers in the cloud is like dropping them from a helicopter into a jungle across enemy lines without so much as an IP address. This talk will cover how to use Puppet to harden cloud servers including certificate and key management, protecting secrets on your hosts, managing dynamic IPs, and overall security best practices. While a few tips will be specific to Puppet and Amazon AWS, most of the techniques would apply in just about any environment.

Update: Kyle’s slides can be found on his web site.
