I need to use LUA to update clients in multiple locations and have configured the Download and Distribution Centers.  A added Endpoint Protection as the only Product.

This seems to offer me a number of sub-components...

Behavioral Crimeware Protection

Firewall Rules

Other Software Updates

Virus Definitions

Do I need all of these to update a managed SEP11 client - if not, which?

What are the first three - I cannot find any documented descriptions?

My inital test download with all of these selected was about 500 mb, which I would prefer to avoid having to distribute to all the remote locations.  Is there some way of reducing this, if I do need all of the above components?

Any helpful advice gratefully received.
