The Lone Wolf and the Enemy Within - 11 Dec 15 by gins




HACKERS now pose more of a threat to world security than nuclear weapons - 

Recent attacks and daily coverage of cyber-threats got me wanting to watch one of my all-time favorite movies, ‘Die-Hard 4.’  Almost nine years ago, it introduced the term ‘fire-sale’ to the masses.  More on this later….

Coverage of the ‘lone-wolf’, with expected focus on traditional terror vectors, underplays the potential damage from cyberterrorism.  Here, I’m not talking about state-sponsored, direct or indirect, but from the individual.  But the attack won’t come through the front door, the area of most focus.  It will come from the inside, and traditional perimeter security tools won’t offer protection.   Even newer tools offering interior protection will be hard pressed to combat a radicalized individual who has slowly moved up through the organization and now has the keys to the kingdom.   How to combat?

Segment It to Save It

At the Gartner Data Center I&O Management Conference this week, Theresa Payton, former White House CIO, did an excellent job of describing current threats and some harrowing statistics. 

  • 78% of cyber attacks start with tricking the user
  • Almost 100% will click on a phishing email
  • 50% will open attachments if they look relevant, such as:
  1. Create target list from attendees
  2. Select source of email from agenda, and attribute to someone important
  3. Use known phrasing and lingo.  Add urgency.
  4. Package trojan within and name ‘Notes from Meeting’ or some other relevant topic.
  5. Send.
The first step is therefore awareness, and a change in behavior that won’t happen overnight (and I’m the first to admit that many times I’ve come close to hitting ‘open’), but as I mention above, this won’t protect against a trusted insider.  The same tools used to radicalize individuals can also be used in the opposite way, helping them build expertise in gaining trust.

This requires more sophisticated ways to protecting data from the inside, not simple and implying an even greater level of control.  The days of ‘superusers’ may need to come to an end, with two-party control the rule.  True role-based access will need to filter down from the Fortune 500 into the smallest of enterprises.  Her suggestion was to start slow, selecting the few critical pieces of data that can’t be compromised at any cost.  She used the example of the presidential calendar, now split between five databases, and only aggregated within the Oval Office. 

The watchword was ‘segment it to save it,’ while including controls that will identify any out of the ordinary behavior.  The natural extension of this is a background process that checks all actions against known per-user heuristics, a curve of sort, flagging anything that looks wrong.  A new security abstraction layer.  Of course this begs the question ‘who watches the watchmen?’   Not insurmountable, but something else to worry about. 

Back to Die-Hard.   

I’m always amazed by how Hollywood portrays government IT infrastructure.   The National Data Administration.  Nice.   The Homeland Security NOC.  I want one.  Right out of Terminator.   When I was in the military, a primary backup site for the US Government looked like a school room, and for those who remember Desert Storm, it was laptops in trailers.  


To the industry’s credit, we’re getting better at portraying IT and hacking, as detailed in a recent Atlantic article, Hollywood is Finally Starting to Get Hacking Right.

And something I had forgotten.   The baddie was Maggie Q.   From the movie, and from a dinner a few years back just north of Toronto.

Snapchat and my Daughters (14 Oct 14 by gins)

By now you've heard of the latest security breach - the Snapsaved (now shut down) Snapchat client hacked and hundreds of thousands of potentially damaging photos posted to 4chan.  Now, although Snapchat itself was not the target, many, my daughters included, post to it, and to be honest, i don't know if they've been using the Snapsaved client (or some other client, yet to be hacked).   My bad!  But we do limit in-app purchases. The problem is that many of these casual applications are no-charge.  And i'm sure that they don't read the small-print when downloading said applications, as to what is saved and what is not.  Where to draw the line?

In a world where Instagram is the new clique, replacing clothes and what kind of house you live in, I can't really cut them off.  But i can give my daughters, ages 10 and 11, guidance, beyond the standard school Internet good citizen briefing on content and bullying.  Guidance that reflects more of the real world, like what happened to that unfortunate girl in Saratoga, just five miles from our house.  And guidance that can be understood by a very distracted ten year-old.

1.  Never post a picture or opinion that you'd not want to have viewed or read by a future employer, by college admission, or even by your close friends.   I know we've heard all of this before.  A scary statistic by the CTIA - 46% of adolescents, ages 11 to 17, have received a message or picture their parents would disapprove of due to sexual content.

2.  The same applies for pictures or opinions of friends (or non-friends).  What goes around comes around.

3.  Never (ever) be put in a position where someone has the opportunity take a picture that you'd not want to see posted.  Something to be said about a buddy system at parties, especially once they hit high school.

4.  Never share private information.  Once again, nothing new.

Over the last year, the CTIA has published some great infographics on www.growingwireless.com.   Worth taking a look.  And within the site, the resources page has a wealth of information spanning smartphone OSs and cellular providers.

Time to have that conversation!
