I wanted to share an article from the November issue of the Public Library of Science, both because it’s interesting reading and because of what it tells us about the state of security research. The paper is “Willingness to Share Research Data Is Related to the Strength of the Evidence and the Quality of Reporting [...]
This is a great video about how much of software engineering runs on folk knowledge about how software is built: “Greg Wilson – What We Actually Know About Software Development, and Why We Believe It’s True” There’s a very strong New School tie here. We need to study what’s being done and how well it [...]
Wade Baker has a quick response to my “Thoughts on the 2011 DBIR and APT,” including the data that I was unable to extract. Thanks!
Following the Diginotar breach, FOX-IT has released analysis and a nifty video showing OCSP requests. As a result, lots of people are quoting a number of “300,000″. Cem Paya has a good analysis of what the OCSP numbers mean, what biases might be introduced at “DigiNotar: surveying the damage with OCSP.” To their credit, FoxIt [...]
The fine folks at Securosis are starting a blog series on “Fact-based Network Security: Metrics and the Pursuit of Prioritization“, starting in a couple of weeks. Sounds pretty New School to me! I suggest that you all check it out and participate in the dialog. Should be interesting and thought provoking. [Edit -- fixed my [...]
In two recent blog posts (here and here), Chris Wysopal (CTO of Veracode) proposed a metric called “Application Security Debt”. I like the general idea, but I have found some problems in his method. In this post, I suggest corrections that will be both more credible and more accurate, at least for half of the [...]
In “Close Look at a Flu Outbreak Upends Some Common Wisdom,” Nicholas Bakalar writes: If you or your child came down with influenza during the H1N1, or swine flu, outbreak in 2009, it may not have happened the way you thought it did. A new study of a 2009 epidemic at a school in Pennsylvania [...]
Hey, I know it’s late notice, but I’ll be speaking at 10:30 EST today on EBRM and the Verizon DBIR: https://www.techwebonlineevents.com/ars/eventregistration.do?mode=eventreg&F=1002809&K=CAA1BC&tab=agenda Alex
I have fundamental objections to Ponemon’s methods used to estimate ‘indirect costs’ due to lost customers (‘abnormal churn’) and the cost of replacing them (‘customer acquisition costs’). These include sloppy use of terminology, mixing accounting and economic costs, and omitting the most serious cost categories.
Both Dissent and George Hulme took issue with my post Thursday, and pointed to the Ponemon U.S. Cost of a Data Breach Study, which says: Average abnormal churn rates across all incidents in the study were slightly higher than last year (from 3.6 percent in 2008 to 3.7 percent in 2009), which was measured by [...]
