He's back.... and why choosing auth matters.

Well first of all thanks to NETGEAR.  I'm back.  This time it should be for good.  But tell me this; why can't I get a router that will take some moderate load on a hot Sydney day and not explode?!?!  Even my new (expensive!) Netgear hardware runs hot (50oC+) under *no* load.  I'm gonna have to casemod this sucker to add a fan if it's gonna last me until Feb '06.

Anyway, authentication.  It's not the first time Crypto-Gram has been mentioned on my blog.  This time it relates to a post therein about the kind of fingerprint readers that have become popular in Keyboards/mice or as USB peripherals, and how with some skill and the right tools and circumstance you can foil them in about the same time it takes to make a sandwitch.

What it comes down to is this (I am drawing from many sources here).  Authentication comes in three factors:
  • Things you know - passwords/passphrases*, PINs, mothers maiden name (how many web sites will ask this!) and so on...
  • Things you are - your retina, your fingerprint^, etc
  • Things you have - Smartcards, USB dongles, key cards, your passport yadda yadda...
If you require 2 forms of authentication and draw from only one pool, then you have only one factor!

(I have a secret about OfficeWorks SAP system, remind me to tell you about it some time...)

Anyway, that's enough for tonight :)
