Presentations available online
Below are recent presentations I've given, in reverse cronological order.
If you're interested in having me present at your organization/function/etc,
just drop me a line. And I'm always available for Security and Linux
- Linux Fest Northwest Talks
- I have two talks at Linux Fest Northwest this
Protocols Illuminated and Shell
Scripting from Scratch. After a long stretch of minimal speaking
engagements (limiting myself to the occasional GSLUG lightening talk)
it was a pleasure to be back at LFNW and see throngs of Linux veterans
and new folk alike.
- The Command line is for Everyone
- An attempt to dispell the "only uber-hax0rs can understand the command line" myth, this talk from Linux Fest Northwest shows how the command line works - arguments, redirection, etc - to remove
the mystery and lead you down the trail to real power. Muahahaha.
- Linux Security Overview, Redux
- I recycled my talk from ISSA for TacLUG,
condensing the 2.25 hour talk into about 1 hour. Many slides were summarized,
skipped, or at least overlooked.
- Practical SSH Encryption, Tunneling, and Automation
- A 1 hour presentation I gave at LinuxFest Northwest
this year. I don't think I should have called it 'practical' because really it
covers more of the essoteric and bizzare hackish things you can (and should)
do with SSH.
- Perl Security Overview
- A 2 hour presentation (written in the same amount of time) I
gave at the November Seattle Perl
Users Group. Overview of common problems and pitfalls when
developing in Perl.
- File Integrity Checking with AIDE
- Jeremy Reed and I tag-teamed this talk. My sections are available here.
- GnuPG/PGP Encryption
- A 1 hour presentation at
overviewing how PGP works, how to create, exchange, and verify keys, and
how to sign and/or encrypt files.
- Covert Channels
- A 1 hour presentation at
discussing various nefarious ways to communicate covertly, from steganography,
SSH and SSL forwarding, to application tunneling such as TCP over HTTP or IP over DNS.
- Crypto Tunnels with SSH and SSL
- A 1 hour presentation at GSLUG
(Greater Seattle Linux User Group) covering how to use SSH tunneling
(LocalForward / RemoteForward) and SSL tunneling (using Stunnel) to protect
your cleartext protocols.
- Linux Security Overview
- A 2 hour presentation at ISSA Puget Sound in July, 2003. Covers Bastille Linux (basic), identifiying and locking down services manually (intermediate) and the kernel-level security (advanced) with traditional root, capabilities, LIDS, and Systrace.
- VPNs and Crypto Tunnels
- A talk about various VPN technologies and cryptographic Tunnels available on Linux, presented at Real World Linux in April 2003.
- Linux: The secureable operating system -- AKA, 'every linux security hook in 60 minutes or less'
- This was a insanely ambitious attempt to cover all linux kernel
security in one hour that I presented at LinuxFest Northwest.
I only made it through 98 of the 130 slides.
