No Podcast This Week

It is with a heavy heart that I have to inform our tens of listeners that unseen forces in the universe have prevented a podcast recording this week. My Scarlett 2i2 tragically died of as-yet unknown causes Tuesday evening. Subsequently, Amazon and the USPS collaborated to ensure the replacement unit, with a guaranteed delivery date of  today, would not be here until Friday or Saturday.  Amazon appears ready to refund the cost of the free second day shipping I incurred as a result of this travesty of logistics.

Until next week my friends…

New logo!

The Defensive Security Podcast marketing department has been griping for a while about the terrible logo that Jerry made almost 2 year ago during a fit of Everclear-fueled “creativity”.

“We can’t file an for an IPO without a decent logo!”

Indeed.

So, we approached the most prestigious ad agency we could find – Weiden + Kennedy – of Old Spice fame – to help develop an image befitting the institution that the Defensive Security Podcast has become. After it became apparent that the ad firm wasn’t going to return our calls, we decided to take another approach and put the logo out for bid on logobids.com.

There were a lot of… interesting…. designs – clearly from people who had not heard the podcast before. And also a lot of really good ones too. The selection process was arduous. Marketing wanted one design, HR wanted another, finance wouldn’t stop complaining about the cost and the sales department was too busy playing golf to participate. We asked for feedback from our twitter followers. In the ensuing chaos, Andy and I picked our favorite. And so, here is our new logo:

Vulnerability Wednesday?

Here is an interesting article on changing the social contract of vulnerability disclosures from the current, though recent, seven day cycle, to one that follows patch Tuesday, or whatever equivalent date the particular software vendor has for patches.

It’s a good idea, but I think the author missed an important nuance: the short 7 day notice is for situations where the discovering researcher has found evidence that the vulnerability is being actively exploited. In other cases where the vulnerability is not being actively exploited, the time frame is 6o days, which is compatible with the author’s idea. Note that the 7 day recommendation comes from Google and is available to read here.

I do not think that it makes sense to wait until after the next patch Tuesday in cases of active exploitation. The point is that users of the vulnerable technology need to know that there is a vulnerability being actively exploited, whether or not a patch is available, so that the user can take steps to mitigate the problem.

Risk Perception Versus Reality

One of the side effects of podcasting is that I read a lot of infosec news on a daily basis and a lot of industry reports.  Sometimes, I see an odd overlap.  For instance, I was reading this article about a survey from McAfee on how long IT professionals believe it would take for them to detect a breach.  The numbers were all over the map, but is described like this:

“… 22 percent thought they’d need a day to recognise a breach, with one in twenty offering a week as a likely timescale.

Just over a third said they would notice data breaches in a matter of minutes, which counts as real-time by today’s standards.

In terms of general security, three quarters  confidently reckoned they could assess their security in real-time, with about the same number talking up their ability to spot insider threats, perimeter threats and even zero-day malware.”

 

The article raises the point that the polled population seems overly optimistic, however I think it needs to be explored a little deeper.

  • Mandiant’s 2013 annual report claims that data breaches take an average of 243 days to find.
  • Trustwave’s report finds that the average to be 210 days.
  • Verizon’s DBIR finds that 66% of breaches in the scope of their report took “months” to “years” to discover.

This is not a minor miss.  This is not “being overly optimistic”.  This is a fundamental lack of understanding of the world we live in.

What concerns me most about this disconnect is how these beliefs are used as an input into risk management processes.  If organizations are prioritizing their security efforts based on the input from internal authoritative sources, such as the 500 people McAfee polled, that breaches will be detected quickly, when in reality they take months, there will be little appetite to make improvements in detection capabilities.

Defensivesecurity.org Is Classified As Porn Site (if you are at Disney World)

I am here on vacation in Disney World, using wifi in the hotel and I’m being blocked.

20130525-223241.jpg

Disney appears to be using an old (I mean old) web filter called the 8e6 R3000 from 8e6 Technologies, now Trustwave. Interestingly, when I check this site’s category using Trustwave’s site here and it is not registered. The site is correctly categorized as “IT” in the other filtering engines.

So, it would seem that Disney World is keying off some element of content on the site, rather than on the Skye’s categorization.
