Firewall of the RWTH Aachen University

Introduction

The main task of a firewall in a security concept is, to limit the reachability of services in a way, that vulnerable and sensitive services are only available, if the security policy allows that.

To enforce this concept the Center for Computing and Communication operates a high performance firewall within the internet uplink of the RWTH Aachen University. This firewall controls the worldwide availability of safety critical services by using binary rules (yes or no).

Furthermore the CCC can operate a firewall on the routers which are installed before the networks of facilities of the RWTH Aachen University, to limit the danger within the network of the RWTH Aachen University. Please contact us, if your are interested.
