April 10th - Tamper-evident boot with Heads by Kyle Rankin

by Allan Cecil

Topic: Tamper-evident boot with Heads When: Tuesday April 10th, 7:30 PM to 9:00 PM Speaker: Kyle Rankin Location: O'Reilly Media, Sebastopol CA in the Tarsier conference room past the metal statue and to the right ( http://nblug.org/locations ) Description: Having a trustworthy boot process is the foundation of the rest of your system's security. If your BIOS, kernel, or initrd have been tampered with, an attacker can hide their backdoor from the rest of the system. This talk will discuss the security threats against the boot process and briefly cover some other approaches to protect against boot-time attacks but the talk will primarily focus on Heads, an open source project that provides tamper-evident boot. I will discuss how Heads works, how it differs from other secure boot approaches, and demonstrate how it protects against tampering. Unless there are security concerns I (Allan Cecil) will be streaming the talk at http://twitch.tv/dwangoAC - see you there either in person or virtually!

We have representatives of several options: * Improving existing hardware by flashing OpenWRT or similar * Building your own router from an old PC or single-board computer * Commercial products aimed at IT professionals We expect a wide-ranging discussion of the pros and cons of each of these approaches, touching on the effort required, security implications, and flexibility of each option. Questions from the audience are welcome. Best, Tom

General meeting tonight: GPG Key Signing Party

by Allan Cecil

Hi all, I'm hoping for a good turnout at this meeting as this is a fantastic opportunity to get PGP keys signed and exchanged with a very useful crowd of people. And by saying that, I mean I'm hopeful that some of the lurkers who are well connected can make it to the meeting (you! yes, you!). This PGP keysigning party is very timely as Yahoo just announced PGP support: http://arstechnica.com/security/2014/08/yahoo-to-begin-offering-pgp-encrypt… ...wait a minute, that's from 2014. Looks like I just got caught re-using an E-Mail from a couple of years ago. Oh well. :) So, before the meeting, run gpg --gen-key and gpg --send-keys --keyserver keyserver.ubuntu.com <Key ID> as necessary then E-Mail the output of gpg --fingerprint <ID or eMail address> to frank(a)nblug.org to allow him to get a list ready (but if you don't get to this, come to the meeting anyway). See you there!

GPG Key Signing Party

by E Frank Ball III

Topic: GPG Key Signing Party When: Tues February 13th, 7:30 PM to 9:00 PM Coordinator: Frank Ball Location: O'Reilly Media, Sebastopol CA, in the Tarsier conference room past the metal statue and to the right - http://nblug.org/locations GPG Key Signing Party: It's time for another GPG key signing. We had one in May 2003 & August 2014. The point of this is to create a web of trust. By signing someones public key, you state that you have checked that the person that uses a certain keypair, is who he says he is and really is in control of the private key. This way a complete network of people who trust each other can be created. This network is called the Strongly connected set. Information about it can be found at http://pgp.cs.uu.nl/ Before the meeting: 1) Generate a public/private keypair with the "gpg --gen-key" command (accept the defaults), see man gpg for more info. 2) Upload your key to a keyserver: gpg --send-keys --keyserver keyserver.ubuntu.com 3) Print out the key fingerprint with gpg --fingerprint Also include your full name, email address, and Key ID#. Bring this to the meeting, and optionally make extra copies to hand out. 4) Email me at frank(a)nblug.org with the fingerprint, email address, full name, and Key ID. I'll have a list of everyone's info to hand out. During the meeting: Verify your GPG key fingerprint on the list I hand out and verify your identity (with photo ID). After the meeting: 1) Download the all of the keys for the fingerprints verified at the meeting 2) add them to your keyring 3) sign them 4) upload your key again.

Yubikey/SmartCards for Linux Security Talk @ NBLUG meeting 2018-01-09

by Robert Thille

Hello NBLUG members! With more and more information coming out about how insecure nearly every computer is, come find out how to make your computer use just a bit more secure... When: January 9th, 2018 7:30 pm Speaker: Robert Thille Location: O'Reilly Media at 1005 Gravenstein Hwy N, Sebastopol, CA in the Tarsier conference room past the metal statue and to the right (http://nblug.org/locations <http://nblug.org/locations>) Title: Enhancing Linux security with a Yubikey/Smart-Card Description: In this presentation, Robert will go over how to setup and use a Yubikey to store PGP keys and PKI certs such that without physical access theft of the keys is just about impossible, and even difficult with physical access. Other security enhancements like hardware password stores (Mooltipass) and air-gapped machines will be covered. Further, I'm sure there will be discussion of the recently disclosed Meltdown and Specter attacks.

Note that our elections are tonight following Frank's talk and seeing as we haven't had any nominations submitted by E-Mail this year we'll be doing that process live at the meeting. Come in person if you can not just to do your civic duty to vote but also to pick up free T-Shirts, stickers, and other shwag from Linux laptop maker System76. We'll also have lots of free O'Reilly books available for the taking at tonight's meeting. Oh, and come for Frank's talk. I'm amazed how far the Chromebook community has come.

Tonight's meeting canceled, use this time to help others instead

by Allan Cecil

Due to the ongoing fires the regularly scheduled general meeting will not be held tonight. There will not be anyone present to unlock doors. Some NBLUG members are still unaccounted for at this time. Please consider using the time you would have spent at the meeting to volunteer, as many evacuation shelters are in need of supplies. I'd like to (ab)use this announcement to highlight the help of one of our sponsors - Sonic.net generously uncapped full bidirectional gigabit fiber service to New Life Christian Fellowship which is one of the many evacuation centers currently open in Petaluma. I witnessed many evacuees there using various devices to either gather news or contact friends and family and I'm thankful for the help from Sonic. Stay safe and see you next month, A.C. ****** President, North Bay Linux Users' Group
