Attack Trees

[Gulsher Bajwa <gulsher_bajwa () yahoo com>]

Hi.  Has anyone here used attack trees as a means to
assess security?  I am currently doing a project as
part of my masters program at UB.  The objective is to
arrive at the security model that is based on sound
metrics.  

Another issue is how does one validate the data that
is fed into a model?

I have looked at a tool called SecurTree that
essentially constructs attack trees.  The company that
designed the tool blatantly states that the values
they assign to the inputs are emperically established.
 That doesn't say too much in terms of validation.

Also, is there any way to profile an attacker?  The
objective is to conduct a capability analysis of
threat agents.

I am sorry if the above sounds vague.  I am fairly new
to Security modeling.  Any guidance will be much
appreciated.

Regards,

Gulsher
