Friday Summary

Rich · November 14, 2008

I have to say, Moscow was definitely one of the more interesting, and difficult, places I’ve traveled to. The city wasn’t what I expected at all- everywhere you look there’s a park or big green swatch down major streets. The metro was the cleanest, most fascinating of any city (sorry NY). I never waited more than 45 seconds for a car, and many of the stations are full of beautiful Soviet-era artwork.

Comments on Database Media Protection

Adrian Lane · November 13, 2008

Rich posted an article on database and media encryption (aka Data at Rest) earlier this week, discussing the major alternatives for keeping database media safe. Prior to posting it, he asked me to preview the contents for accuracy, which I did, and I think Rich covers the major textbook approaches one needs to consider. I did want to add a little color to this discussion in terms of threat models and motivation- regarding why these options should be considered, as well as some additional…

Healthcare In The Cloud

Adrian Lane · November 13, 2008

Google is launching a cooperative program between Google and Medicare of Arizona. They are teaming up to put patient & health care records onto Google servers so it can be shared with doctors, labs and pharmacies.

I was reading this article over at NetworkWorld today on a study by a commercial DNS vendor that concluded 1 in 4 DNS servers is still vulnerable to the big Kaminsky vulnerability.

Cloud Security Macro Layers

Rich · November 12, 2008

There’s been a lot of discussion on cloud computing in the blogosphere and general press lately, and although I’ll probably hate myself for it, it’s time to jump in beyond some sophomoric (albeit really funny) humor.

Data Discovery & Classification

Adrian Lane · November 11, 2008

I was reading the RSA report on the Torpig/Sinowal trojan while stuck at the airport for several hours last Thursday. During my many hours of free time I overheard some IT executive discussing the difficulties of implementing data discovery and classification with his peers. I did not catch the name of the company, and probably would not pass it along even if I had, but the tired and whiny rant about their associated failures was not unique. Perhaps I was a bit testy about having to sit in an…

I do believe I am officially setting a personal best for the most extended blog series. Way back in February, before my shoulder surgery, I started a series on database encryption. I not only don’t expect you to remember this, but I’d be seriously concerned about your mental well being if you did. In that first post I described the two categories of database encryption- media protection, and separation of duties. Today we’re going to talk more about media encryption, and the advantages of…

When we talk about security threats we tend to break them down into all sorts of geeky categories. Sometimes we use high level terms like clientside, targeted attack, or web application vulnerability. Other times we dig in and talk about XSS, memory corruption, and so on. You’ll notice we tend to mix in vulnerabilities when we talk about threats, but when we do that hopefully in our heads we’re following the proper taxonomy and actually thinking about that vulnerability being exploited, which…
