Cyber Jumps The Shark

By
Wednesday, September 17, 2014 at 12:23 PM

To “jump the shark” is a symbol for when a phenomenon (usually a TV show) reaches its apex and begin declining in quality.  It’s named after a famous “Happy Days” episode where Fonzie gets on a water skis and actually jumps over a shark.  Though usually directed at artistic media, the phrase sometimes resonates with . . .

By
Sunday, September 7, 2014 at 10:24 AM

Well, summer is over now and it’s time to get back to the real world.  For starters, I had a chance to participate in a podcast for The Security Ledger on the topic of the vulnerability of the Internet of Things.  Here’s a summary and the full podcast is at the Security Ledger web page: . . .

Reflections on DefCon and Black Hat

By
Tuesday, August 12, 2014 at 10:53 AM

I had the opportunity to go to Las Vegas last week to attend the annual events surrounding DefCon and Black Hat.  DefCon is a 22-year old convention of hackers (a/k/a security researchers) and Black Hat is its more “corporate” adjunct.  It tells you almost everything you need to know about the difference between them that . . .

Dan Geer Cybersecurity Keynote at Black Hat

By
Friday, August 8, 2014 at 8:47 AM

Dan Geer gave this keynote address at the Black Hat conference yesterday.  It is entitled Cybersecurity as Realpolitik.  It begins with some general thoughts on the state of play in cybersecurity, addresses ten pressing policy issues, and is characteristically filled with insights throughout.  The speech is very much worth a read.  Or a watch – . . .

Everybody is Vulnerable

By
Wednesday, July 30, 2014 at 8:01 PM

Even the vaunted Israelis. “A Chinese hacking team previously accused of being behind raids against US defence contractors has been accused of a new data heist: plundering the tech behind Israel’s Iron Dome missile defence system.”  Apparently this was in 2011-12 so it isn’t connected to the current conflict — except, of course, that it . . .

True Lawfare — The Fight to Seize Iran’s Domain Name Continues

By
Wednesday, July 30, 2014 at 5:24 PM

A month ago, we wrote about an effort by several plaintiff’s lawyers, representing terrorist victims, to seize the Iran domain name (.IR).  Turns out there was even more to it than we were aware of at the time, as the same group of lawyers have filed similar writs of attachment against Syria (.SY) and North . . .

Why Indictments Won’t Stop China’s Cybersnooping

By
Tuesday, July 29, 2014 at 8:58 AM

The Chinese government and its proxies have recently ratcheted up harassment of U.S. IT firms doing business in China.  In the last week, China has deployed its antitrust laws against Qualcomm and Microsoft.  This comes on the heels of recent attacks in China on Apple and Cisco and IBM.  China has also increased its harassment of . . .

On NSA’s Subversion of NIST’s Algorithm

By
Friday, July 25, 2014 at 2:00 PM

Of all the revelations from the Snowden leaks, I find the NSA’s subversion of the National Institute of Standards’s (NIST) random number generator to be particularly disturbing. Our security is only as good as the tools we use to protect it, and compromising a widely used cryptography algorithm makes many Internet communications insecure. Last fall the Snowden . . .

CISA Boom Bah …

By
Tuesday, July 22, 2014 at 4:53 PM

Sorry, I just couldn’t resist the title which does not reflect my true feelings about CISA, the Cybersecurity Information Sharing Act of 2014.  Approved earlier this month by the Senate Intelligence Committee, this bill awaits Senate floor action.  In the current environment, I think its legislative prospects are modest (though perhaps we might see it . . .

A Taxonomy of Cyber War IHL Questions

By
Thursday, July 3, 2014 at 11:50 AM

I have been asked to write a chapter, tentatively entitled “Law and Warfare in the Cyber Domain,” for the next edition of Moore, Roberts & Turner, eds., National Security Law.  As part of that effort, I have been thinking about where the gaps are in the domain of international humanitarian law as applied in cyberspace.  . . .

While the rest of the world is watching the Supreme Court’s final decision day of the year, it’s been a busy time in the cyber world as well.  Herewith seven (!) bits and bytes of interest, in no particular order: Facebook’s Psych Experiment.  You’ve no doubt read that Facebook manipulated news feeds as an experiment. . . .

Seizing Iran’s Domain Name — .IR

By
Friday, June 27, 2014 at 3:08 PM

As we have noted in the past, there is a brewing fight over who controls the naming function for the internet.  I suspect that some who’ve read these posts have wondered if they were truly germane to national security — the nominal subject matter of this blog.  Today, we find a bit more evidence of . . .

How Dumb Is This?

By
Monday, June 23, 2014 at 12:08 PM

I yield to nobody in my capacity to be surprised by Congress, but sometimes even I get a bit of a shock.  I totally get the idea that everyone is angry at the NSA.  And, indeed, I’ve spoken publicly about my particular disappointment that the NSA may have (if reports are accurate) deliberately degraded encryption . . .

The Strange Demise of TrueCrypt and What It Says About Cybersecurity

By
Wednesday, June 18, 2014 at 11:31 AM

A small earthquake happened at the end of May – a well-regarded, widely known encryption program called TrueCrypt shut its doors. For those who care about surveillance, encryption, and open-source methodologies, the change was abrupt and disturbing. It’s the type of thing that goes unnoticed by the broader public, but has quiet effects that should . . .

Rogers Throws A Flag

By
Wednesday, June 18, 2014 at 8:00 AM

Last week, as I noted in Bits and Bytes, the Chairman of the FCC, Tom Wheeler, gave a speech at AEI in which he claimed a role for the FCC in advancing cybersecurity. Today, Rep. Mike Rogers threw a flag.  In a letter to the FCC, he wrote that the speech “lead[s] us [Rep. Pompeo . . .

The Chair and Vice-Chair of the Senate Select Committee on Intelligence, Senators Feinstein and Chambliss have introduced a draft cybersecurity information sharing bill.  Early coverage of the bill from Inside Cybersecurity is here.  My own quick analysis: The requirement to remove personally identifying information from shared cyber threat information is both critical to securing buy . . .

Along with three co-authors, I’ve just released a paper through The Heritage Foundation entitled: “Protecting Internet Freedom and American Interests: Required Reforms and Standards for ICANN Transition.”  In the paper we lay out a series of recommendations for the transition of control over the internet naming function to ICANN.  Here is the abstract: The U.S. . . .

“Greetings from the Chinese Embassy”

By
Friday, June 13, 2014 at 8:00 AM

“Greetings from the Chinese Embassy.”  That’s how the email opened.  It was an invitation to lunch (or tea) with a counselor in the embassy to discuss cybersecurity.  How could I say “no?”  So I went to lunch the other day.  It was, on the whole, altogether pleasant, and relatively unsurprising, but worth noting nonetheless for . . .

New McAfee/CSIS Report on Cybercrime

By
Monday, June 9, 2014 at 11:56 AM

I participated today in a CSIS/McAfee roll-out of their latest report on the economic impact of cybercrime.  Their bottom line is that cybercrime has an annual effect of roughly $455 billion globally, with 200K jobs lost in the US alone as a result.  A nice summary of the report by the Washington Post is available here, . . .

Paul on Audible on Cyber

By
Saturday, June 7, 2014 at 11:07 AM

I listen to a lot of books from audible.com, and especially enjoy the “Great Courses” series, which in my experience is, on a number of topics, very high quality.  I just this morning noticed that our own Paul Rosenzweig has a course called Thinking About Cybersecurity: From Cyber Crime to Cyber Warfare.  I have not yet listened to it . . .
