File watch on group

I would like to put a watch on a file for rwxa for a File being accessed by someone who is not in the same group as the file. For example: I have a file /var/myapp/logs 640 ntsw:ntsec So basically I have my application log files that are readable by anyone in the ntsec group. However if someone in another group like ntadm group tries to rwxa that file I would like to log it. Can this be done using an audit rule?
