Security Issues Resulting from Interoperability

Once coalition networks are established, the vulnerability of information systems may increase. Internal propagation of a worm with the characteristics of, for example, “Nimbda” or “Code Red” can generate internal broadcast storms behind the network firewalls. There are significant limitations to applying simulation information security issues. Most security vulnerabilities occur at the end points and evaluating the actual systems best assesses these vulnerabilities. However, network simulation is an obvious choice for evaluating the impact of primary and secondary packet storms on large, internal networks.
