This proposal addresses two fundamental gaps in network security: the security administrator's inability to know what is happening on his network and the ease by which attackers can circumvent existing network monitoring tools such as the Network Security Monitor (NSM). Without filling these gaps, we cannot claim that we have control over, or integrity within, our computer and communication infrastructure. We introduce three broad classes of threats: new servers, rogue servers, and masquerading servers; and demonstrate how easily they can be introduced into your environment and how they easily compromise the integrity of firewalls, network monitors, and TCP wrapper. We then discuss how Network Radar can be used to fill these gaps and reestablish integrity within your network.
