Yes, it is a bit like Minos, but (a) considerably faster than the Minos 
implementation on Bochs (but then Minos was intended as a hardware 
solution, and Argos is not), and (b) we have actually done a bit more 
than what we have now released. For instance, we also implemented an 
automated signature generator, that makes an attempt to figure out which 
application is attacked (or indeed the kernel) and generates a Snort 
signature that can be used to block the worm. It is currently not stable 
enough to release. We do have a TR that describes how it works. Drop me 
an email and I will send it to you. In addition, we are working on a 
more advanced signature generator.

My knowledge of Minos is admittedly limited, but I also think it simpler 
to 'do stuff' in Argos (e.g., deal with register spring attacks) as we 
have convenient access to all aspects of the machine and both physical 
and virtual addresses. I realise this is a little speculative - perhaps 
a Minos person could comment.
