I have an ASA 5515-x running 9.03, and have AnyConnect clients running version 3.1.04063. I am licensed for Advanced Endpoint Assessment and CSD. The issue I am having is when I client connects using TrendMicro AV, and the Trend service is stopped, the Endpoint Assessment recognized this and attempts to start (which is good!), but it fails to start with the following warning logged:
you should be able to do this using DAP (Dynamic Access Policies) on the ASA, i.e. create a DAP rule that denies the connection if endpoint.av["TrendMicroAV"].activescan has a value of false, and a default rule that allows all other connections.
