I’m thrilled to be invited to share my perspective after taking a rather unique MOOC offering - Economics of CyberSecurity, organized by TU Delft. This was a 5-week course covering several aspects of ‘Information Security’ from the perspective of ‘security economics’, which is the discipline that has been evolving since ...

Jay & I cover dashboards in Chapter 10 of Data-Driven Security (the book) but have barely mentioned them on the blog. That’s about to change with a new series on building dashboards using the all-new shinydashboard framework developed by RStudio. While we won’t duplicate the full content from the ...

This morning, both David Severski & Gabe the Engineer shot me links to the MC2 Workshop on Data-Driven Approaches to Security and Privacy that was held at the University of Maryland recently (Jan 8-9).

I couldn’t find any proceedings or presentations from that conference, but I did take a stroll ...

Need an opinon about the Sony hack?

There are a lot of opinions out there attributing the recent breach of Sony Pictures Entertainment to a variety of sources. Let’s face it, you probably don’t know who hacked Sony. Unfortunately in the world of information security it is pretty ...

While there’s an unholy affinity in the infosec commuinty with slapping IPv4 addresses onto a world map, that isn’t the only way to spatially visualize IP addresses. A better approach (when tabluation with bar charts, tables or other standard visualization techniques won’t do) is to map IPv4 ...

As I was cruising through the RSS feeds this morning, I came across this post by Daniel Kennedy on the 451 Research blog that included this chart:

Now, 451 is my personal favorite industry research firm both as a data dude and as a former F100 executive. They’ve got ...

I was recently presenting on the use of statistics for risk analysis at the SIRACon conference held in Minneapolos (Oct. 9th and 10th, 2014). I was explaining how models and algorithms work at a high level: given one or more observations and the outcomes, we build models or algorithms to ...

Since the previous post was fairly popular, I went ahead and built a small shell script (also below) to ease the process of building the OS X Shiny-gist application.

After copying the script to a place you can run it from in your PATH and executing a “chmod a+x ...

I was playing with some non-security-oriented R+Shiny code the other day, and thought that Shiny apps would be even more useful if they were double-clickable applications that you could “just run”—provided R was installed on the target system—vs have to cut/paste code into R. Now, I ...
