Spread does not implement any particular access control functionality
itself. However it does support a complete API for adding access control
and authentication methods of your choice without changing Spread code.
There is a modular framework with a standard set of hooks.

The details can be found in the paper:

In the Spread source release you can see some tiny sample modules which
provide IP based access control (you can restrict which IP addresses
clients can connect to the server from). 

Also, an example implementation of a user/password module exists in the
source code -- however this is very insecure and isn't meant to be used
itself, it is just an example.
