Abstract: An intrusion detection security system (IDSS) guards a server against vandals' attacks such as denial of service, distributed denial of service, and common gateway interface attacks. An incoming source address is compared with the contents of a database of privileged addresses. If the incoming address is present in the database, the IDSS instructs protective equipment such as a firewall or router to allow the incoming message to pass to the web server despite any ongoing attack, thus allowing messages from customers or suppliers, for example, through. Otherwise, the IDSS checks a database of blocked addresses. When the incoming address is absent, the IDSS writes the address to the database of blocked addresses and instructs the protective equipment to block subsequent messages from the incoming address.

Abstract: System and method for storing in a generalized format, and representing on a graphical user interface, the topology information for a plurality of logical and physical resources in a heterogeneous computer communications network. Topological data for each network resource is encoded using a collection of record structures having a tabular format and stored in a plurality of topology information element tables which are categorized further as data element tables, relationship element tables and auxiliary element tables. The rows in the tables representing discrete data elements are recursively processed and correlated and presented as a generalized topology display via a user interface.
