TaoSecurity Blog

This is the sort of story that starts as a comment on Twitter, then becomes a blog post when I realize I can't fit all the ideas into one or two Tweets. (You know how much I hate Tweet threads, and how I encourage everyone to capture deep thoughts in blog posts!) In the interest of capturing the thought, and not in the interest of thinking too deeply or comprehensively (at least right now), I offer seven security strategies, summarized. When I mention the risk equation, I'm talking about the idea that one can conceptually image the risk of some negative event using this "formula": Risk (of something) is the product of some measurements of Vulnerability X Threat X Asset Value, or R = V x T x A. Denial and/or ignorance. This strategy assumes the risk due to loss is low, because those managing the risk assume that one or more of the elements of the risk equation are zero or almost zero, or they are apathetic to the cost. Loss acceptance. This strategy may assume...

In the September/October issue of Foreign Affairs magazine, Richard Clarke and Rob Knake published an article titled " The Internet Freedom League: How to Push Back Against the Authoritarian Assault on the Web ," based on their recent book The Fifth Domain . The article proposes the following: The United States and its allies and partners should stop worrying about the risk of authoritarians splitting the Internet.  I nstead, they should split it themselves, by creating a digital bloc within which data, services, and products can flow freely, excluding countries that do not respect freedom of expression or privacy rights, engage in disruptive activity, or provide safe havens to cybercriminals... The league would not raise a digital Iron Curtain; at least initially, most Internet traffic would still flow between members and nonmembers, and the league would primarily block companies and organizations that aid and abet cybercrime, rather than entire countries.  Governm...

Nineteen years ago this week I registered the domain taosecurity.com: Creation Date: 2000-07-04T02:20:16Z This was 2 1/2 years before I started blogging, so I don't have much information from that era. I did create the first taosecurity.com Web site shortly thereafter. I first started hosting it on space provided by my then-ISP, Road Runner of San Antonio, TX. According to archive.org, it looked like this in February 2002 . That is some fine-looking vintage hand-crafted HTML. Because I lived in Texas I apparently reached for the desert theme with the light tan background. Unfortunately I didn't have the "under construction" gif working for me. As I got deeper into the security scene, I decided to simplify and adopt a dark look. By this time I had left Texas and was in the DC area, working for Foundstone. According to archive.org, the site look like this in April 2003 . Notice I've replaced the oh-so-cool picture of me doing Ame...
