They are all active, but can be switched off by authorized users, if  
CONFIG_RSBAC_SWITCH has been selected (default).

The default configuration is designed to get your system up without  
trouble, so you might not notice the modules are active. /proc/rsbac-info/ 
stats as well as the rsbac_init() boot messages tell you which models are  
currently supported. If you did not switch them off (what generates a  
syslog warning message in all cases), they are all active.

All policies are fully implemented and (hopefully) usable as described in  
models.htm. My favourite is a combination of AUTH, RC and ACL. RC might me  
left out when ACL groups have been added.

All decisions are based on the process requesting them. Since a process  
runs a program from a file in the name of a user, process, file and user  
attributes are taken into account.

I do not (yet) know the thirdpig model, so I am not sure about your  
question. It is possible that the thirdpig model could be implemented as a  
RSBAC model.
