Do the Amazon 2-Step... Now!

   It's not a new song or a new dance...  Amazon has just announced 2-step, aka 2-factor or multi-factor, authentication for online logins!  It's overdue but I'm glad it's here.

   We've talked about 2-factor authentication in the past so I won't go deeply into it in this post.  The important take-away is that Amazon now offers this service and you should use it!

   Here's an overview article and here's a great step-by-step with screen shots.  I set this up for my account and it was really easy using my phone and Google Authenticator.  You can also use text messaging, or setup text messaging as a backup method.

   The main reason that 2-factor is good and important is that it prevents an attacker, who has stolen your userid and password, from logging in as you.  This is because they would need to have your smartphone in addition to the userid and password! (yes, there are other methods as well).

The Secret Life of Passwords

   I've written about passwords plenty of times in the past.  Passwords are one of the main security touch-points for people, and it's often not a pleasant experience.

   As we've discussed, it's hard for people to pick good passwords and remember them.  So users need "tricks" to help the memory.  One way I've told people to construct a password is to base the password on an embarrassing moment in your life - that way you won't forget the password and you also won't tell it to anyone else.

   Apparently people have been using that, and similar, methods.  NY Times reporter Ian Urbana wrote a great piece on this called "The Secret Life of Passwords".  He asked people to tell him their passwords - yes, you shouldn't do that - but also the story behind the passwords.  There are some very interesting stories.  People seem to memorialize a part of their life in their passwords!  You can read the full story here.  Leo Laporte did a great interview with Ian in the Triangulation podcast.  You can hear that here.

   I'd like to focus to two aspects of this story that jumped out at me.

   First is the story of Cantor Fitzgerald.  They are a large financial firm who were headquartered at the World Trade Center in 2001.  When the terrorist attacks hit the towers, Cantor Fitzgerald over two-thirds of their employees were killed.  That was tragic.

"Who Am I?" (or, Who Was I?)

   I like the story of Les Mis.  I definitely like the musical.  I was not wild about the movies.  The book is definitely a good, and very long, read (or listen!).

   At it's core, Les Mis is a story about Identity Fraud!  It's the story of a man, seemingly wrongly convicted, who operates under a false identity in order to be able to live his life.  It's a common literary theme, used in stories like Martin Guirre, The Count of Monte Cristo and Matchstick Men.  In "olden times", Identity Fraud penalties were very serious. Today... not as much.  Last time we started a discussion of Identity Fraud - we'll continue our discussion of this topic.


   Breaches of online merchant websites and databases get a lot of media attention.  But there are many ways ID fraud is committed including:
  • Shoulder Surfing - this means someone looking over your shoulder, for example when you enter your PIN at an ATM
  • Dumpster Diving - it's amazing what people throw away
  • Mailbox theft - checks, financial statements and other sensitive documents get stolen from mailboxes
  • Stolen purse, wallet, laptop, tablet, phone - these all contain plenty of personal information
  • Social Engineering - be careful about what information you give out about yourself
  • Phishing - email or phone - con artists will call or email pretending to be your bank, law enforcement or other authority and ask you for information.
  • Social media - do you really know who your "friends" are?... there are all kinds of requests and information gathering schemes
  • Copy-cat websites - it's pretty easy for scam artists to create a fake site that looks just like your bank's website, perhaps with a misspelled URL like nationa1bank.com (that's a one instead of an L), and then collect the info you enter.
  • By known or unknown thieves! - some ID thieves know their victims.

   So many choices!

Are You a "Target"?

   By now, most of you have probably heard about the Target credit card information breach.  This is very big here in Minneapolis, home of Target.  All the details aren't out yet but it appears that credit card information for brick-and-mortar stores between Friday Nov. 27 ("Black Friday") and Sunday Dec. 15.  Here are some articles covering the story.  Here's Target's response and an FAQ.

   I'd like to talk a bit about next steps.  If you've been the victim of a data breach... what next?

   First... for consumers.  Target is a retail company and the direct victims of the breach are those of us who shopped at a Target store during the dates in question.  Consumers have two concerns here: credit card fraud and identity fraud. (I don't like the term "identity theft" even though it is commonly used.  No one can steal your identity... you still have it.  They can improperly discover, and misuse, the details... a.k.a. fraud.)

Rhymes with Assword

   Here we go again with more password-related problems.  You can't make this stuff up.  Well, you can but the truth is stranger.

   By now, most people have heard about the Adobe website breach.  I won't go into too many details but you can read Adobe's summary here, and here is a detailed review by Sophos.

   And, after I wrote this post I see that the This Week In Tech (TWIT) show on the great Twit TV network did a show of the same name (go to 1:56:20 in the show). Great minds think alike!  If you read the Sophos report you will see that someone used the phrase "rhymes with assword" as their password hint.

   There are a few key points to review:
  • A new record!  This breach has now set the new record for largest number of compromised accounts, 152,000,000, beating previous noteworthy large breaches including those from Sony, TJX and Heartland.

So What's the Authentication Answer? - 3 Factors of Fail (part 7 - last!)

   We've been discussing the authentication problem for the better part of two months, and now it's time to wrap things up.  If you've gotten to this post through a link but haven't read the rest of the series, it starts with part 1 here.

   Each of the 3 factors of authentication have serious issues when used individually.  The challenge is that we need to log a person into a system or application in a way that reasonably assures the person is who they say they are and has rights to the system.  And, perhaps most importantly, any method we use has to work well for people!

   So, how do we find a solution?

   The key is to think about the user and the use.

Multi-Factor Fail - 3 Factors of Fail (part 6)


from: brainyquote.com
   In December I was at the NG Security Conference in Austin, TX.  We had a fantastic discussion with a group of key security leaders focusing on this "quote" and how it applies to information security.  I say "quote" because there is some question as to who said this or if anyone actually did!

   As I've been saying throughout this series of posts, it seems that this statement is exactly what we are doing in the world of authentication!  None of the typical factors of authentication have really solved our authentication and access problems, yet we continue to use the same mechanisms over again.

The 4th Factor? - 3 Factors of Fail (part 5)

   Welcome to the next installment of my ramblings on authentication, 3 Factors of Fail.  So far we have discussed the classic 3 factors of authentication in parts 1, 2, 3 and 4.

   In recent years some additional authentication assurance methods have been grouped to form what some call the 4th factor of authentication.  This is also called risk-based, location-based or adaptive authentication.  It could also be called "somewhere you are" or "something you are doing".

   The basis of this method is in establishing a rich profile of the user.  This can include:
  • the machine used for access;
  • software used;
  • time or day of accesses;
  • IP address(es) used;
  • what country the connection comes from, or;
  • what actions the user attempts.

Something You Were - 3 Factors of Fail (part 4)

   Today we'll continue our discussion on problems in the world of authentication.  Here are links to parts 1, 2 and 3.

   The 3rd form of authentication is typically called Something You Are.  We typically think of this as some kind of biometric indicator like fingerprints.  But this is probably the earliest and most basic form of authentication used in human or animal species.

   Animal species can identify members by sight, but more often scent or sound.   In addition to the traditional 5 senses, some animals have senses that humans do not, like echolocation, to help identify "friend or food".  Here are some interesting articles.

   Human babies can identify their mother by smell and sound.  People have used visual recognition as a primary identification method for most of the existence of the human race.  Of course, visual recognition can be spoofed. And there are other reasons why visual recognition may not be the best identification method.
