US Patent 7627900 Attack graph aggregation

Disclosed is framework for aggregating network attack graphs. A network may be represented as a dependency graph. Condition set(s), exploit set(s) and machine set(s) may be generated using information from the dependency graph. Exploit-condition set(s) may be generated using the condition set(s) and the exploit set(s). Machine-exploit set(s) may be generated using the exploit-condition set(s) and machine set(s).
