What are the general considerations for protecting the network ?
The security of multiple systems are of same magnitude of importance as the security of the interconnecting network. It is desirable to limit the connection to outside networks to those hosts which do not store sensitive information. All access to and from the local network must be made through a single host computer that acts as a firewall. Keep the network simple by minimizing the number of network interface points between the internal and external network. Only authorised traffic is allowed to pass via the internal network. If possible, use multiple authentication systems to monitor the users. However, network security only covers a small area in the overall security system, the data owner is also responsible for the security of the data.
