Access Control

[Link is broken] Bank (

We usually think of access control in terms of identification, authentication, and authorization: accountability tends to get left to last. This story was interesting in that the problem stems from a failure of accountability.

A bit more sophisticated than optical character recognition.

[Resource no longer exists] DataLossDB (

The Open Security Foundation’s (OSF) DataLossDB project is an interesting resource for information about data and confidentiality breaches.

An attempt at a standard for penetration testing. Given the complexity of drawing up a pentest contract, I’m all for the idea, but I’m not sure how well this one works out. Probably needs more work.

Passwords and Passphrases


[Page is gone] hard passwords (,9171,2089349,00.html)

Cute essay about password choice (although not much useful help).

[Link was broken – linked to possible new URL] Inkblot password generator/reminder (

[Link was broken – linked to possible new URL] Naked password (

OK, this is probably a bad idea, but it does make some points about password choice. This is a system that you can install along with your password choice, or password change, feature. As the user enters the password, the password is analyzed for strength (length, characters, non-alpha, etc). The stronger the password the more of a picture of a lady is … revealed. On the one hand, it provides motivation for choosing stronger passwords. On the other, it may distract the user from memorizing the password. On the third hand, it may violate company policy, or open you to sexual harassment charges. Any takers for finding some other means of motivation that is less distasteful or troublesome?

WPACracker (

Polly wanna crack a WPA network? A cloud based cluster is offering to help out, for a small fee. You send them a data capture, and they run a 130 million word dictionary against it, in as little as 20 minutes. Do you trust them? Are they going to be used to crack WPA networks? Is this sufficient impetus to move to WPA2? Are you going to create a longer passphrase?
