To make the system more useful and increase the amount of traffic we
receive, we allow all CoDeeN nodes to act as ``open'' proxies,
accepting requests from any client in the world. However, this choice
also opens the doors to many security problems. In this section, we
discuss some of the problems we encountered during the early
development and testing of CoDeeN, and the measures we took to deal
with these problems.
For the purposes of
discussion, we have broadly classified the problems into those dealing
with spammers, bandwidth consumption, high request rates, content
theft, and anonymity, though we realize that some problems can fall
into multiple areas.
