This week I would like to draw readers’ attention to an article that appeared in Wired at the end of last year. Written by Mat Honan and entitled Kill the Password: Why a String of Characters Can’t Protect Us Anymore, it makes for really interesting and alarming reading.
The author starts by explaining that he lost all of his digital life last year as his accounts were hacked, an event that lead him into investigating online security and how it is breached.
What he discovered is not for the faint hearted. The linking together of different accounts using an email as username means that any seriously interested party with a little time on their hands and very little money can relatively easily get into a single account, and from there into the others.
His conclusion is that the culture of using passwords for security is outdated, a thing of the past and that anyone who tells you otherwise is either deluded or trying to convince you of something that is not true.
Worst passwords of 2012
The availability of information is a problem because of the personal question access to resetting your password. Mother’s maiden name, place born etc. are easy things to find out about anybody through ancestry sites or other documents. Once you have somebody’s email address, you try to reset the password using the personal questions through the provider’s website. The answers might be on Facebook, or on their blog, or maybe intuitive, but they are out there.
Then to the customer services rep that you speak to by phone. They are people and can be misled. The article contains a transcription of a conversation between a hacker and one of these people. As the user needs to be able to reset the password they are offered a series of questions that get easier and easier to guess. Names of best friends is possible using Facebook or other social network publications, but if not try favourite food or others, but the example given is name of one of the files in the account. Try Google, Amazon, Personal, one will be right.
So the problem is that the system needs to be flexible and easy enough to use, so we must be able to easily change our passwords, but this makes security impossible.
How can this problem be addressed? Here the trade off is privacy. If the company knows you, through your search histories, places you have been, where you work and what you like to do they might better be able to tell if the password reset-er is you, but you lose any privacy you think you might have.
Voice recognition can be tricked using recordings, biometrics and fingerprints too. Once a system uses these things that cannot be changed or reset the problem is magnified. If I have a fingerprint lifted from a screen I can use it to get anywhere and new fingers are hard to come by these days, so what do you use next?
The article poses these problems from the point of view of somebody who has been hacked, but the author also looks at who these hackers are and even meets a couple. It is big business in certain circles, particularly in the Russian speaking world where organized crime has a large stake and makes a lot of money through stealing identities and all that follows. In other circles they are just “kids” having some fun wreaking havoc.
There are a few simple strategies outlined in this (not short) article that are worth following but none are foolproof, and that is a lesson we could all learn from. Just a word of warning, it contains some harsh language.
On a lighter note happy new year to everyone, and my mum’s maiden name was Windsor (no relation to either Barbara or Elizabeth).
There is only one exam that must be successfully completed to earn this IBM certification, and that is the Test COG-645 – IBM Cognos 10 BI Multidimensional Author. The knowledge and skill sets that are necessary for successful completion of this exam include Windows experience, web functionality experience, and the ability to produce basic chart, crosstab, and list reports.
