An Artistic Departure

Mon, 23 August 2010 15:24:41 GMT

I've gotten bored of digital photography; it's time to mix things up a bit.

The Anatomy of Security Disasters

Thu, 03 May 2009 15:24:41 GMT

Security problems begin with bad management and lack of vision.

Interviewed on the Command Line Podcast

Thu, 17 May 2007 15:24:41 GMT

Compared to a point and click interface, the command line is much faster and less likely to give you carpal tunnel syndrome. But I'm actually referring to the podcast! They interviewed me a couple weeks ago.

Revisiting the Ultimate Firewall

Fri, 2 Feb 2007 10:37:12 GMT

A silly firewall graphic on a powerpoint presentation inspires me to load the pickup truck with hay and diesel.

Web Site Defacement With Search Engine Slam

Sun, 7 Jan 2007 19:37:12 GMT

Between yesterday afternoon, when I published my last article, and this morning, someone defaced my site. But unlike the site defacements of the 90s this one was intended to be subtle. Looks like an attempt to tweak search ratings.

Playing With Execution Control

Fri, 5 Jan 2007 17:37:12 GMT

For years I have been saying antivirus is stupid, and bemoaning the lack of a decent executable whitelister. After experimenting with Windows' execution control (ick!) and PrevX (grr!) I found a piece of freeware I really like.

My old code is full of holes.

Wed, 3 Jan 2007 15:37:12 GMT

I got a chance to experiment with the state-of-the-art in source code security analysis tools, and ran it against my fifteen-year-old firewall toolkit (FWTK) code-base. Much to my horror, I discovered that my old code had a number of buffer overruns. I also ran the analysis tool against sendmail, Imapd, BIND, and postfix.

Point/Counterpoint with Bruce Schneier

Mon, 11 Sep 2006 11:58:51 GMT

What is "Strategic Software"? I think we've been completely asleep at the switch over a critical issue. In fact, it's so critical it's best everyone continue to ignore it.

Audio interview on The Silver Bullet

Gary McGraw interviews Marcus on various security topics and random stuff, for IEEE Security and Privacy podcast.

Hard Disk Encryption Revisitted

Sat, 24 Jun 2006 17:26:57 GMT

I have no idea why I was lazy about installing hard disk encryption. It's free. It's easy. What's not to like?

Two Great Articles

Thu, 11 May 2006 19:28:00 GMT

A discussion of and links to two brilliant analytical articles by Richard Feynman and Franklin "Chuck" Spinney.

Abject Failure

Thu, 11 May 2006 15:28:00 GMT

Apparently I'm not the only crazy out there who believes "information security" is an utter disaster.

Songs of the Damned

Sun, 07 May 2006 15:28:00 GMT

A friend forwarded me a link to a corporate motivational song for one of the largest computer security companies in the industry. To say it's horrible is an understatement.

Walkthrough: making a simple 3D photo effect

Sun, 09 Apr 2006 15:28:00 GMT

A walkthrough of using photoshop and a slider bar to produce a 3D effect photo.

Engineering Discipline

Sun, 26 Mar 2006 15:28:00 GMT

An improvised dinner address, delivered without powerpoints and after a few too many bottles of beer. I must make an apology and correction to this talk - I mentioned James Buchanan Eads as the architect of the Golden Gate Bridge, which was wrong. I had Eads, who designed the Mississippi bridge confused with Joseph Strauss, who designed the Golden Gate. The objective of this talk was to take the high ground with respect to treating computing as an engineering discipline, instead of the kettle of kludges that it has become. I realize it's very very idealistic stuff.

Do It Yourself Dealy

Sat, 22 Oct 2005 15:28:00 GMT

"Lee Harvey Oswald could not have fired 3 aimed shots with a scope-sighted bolt-action rifle in 10 seconds. Nobody can; it's too hard." Oh? Really?

Why I have resigned from the SANS NewsBites editorial board

Sat, 10 Mar 2012 13:00:30 GMT

Computer security practitioners should not trade in hearsay!

A view of marketing at RSA Conference, perched on platform shoes

Tue, 19 Feb 2013 10:00:30 GMT

Misogyny or stupid marketing? Take your pick.
