CAESARS Framework Extension: An Enterprise Continuous Monitoring Technical Reference Architecture (Draft) [open pdf - 1MB]
"This publication presents an enterprise continuous monitoring technical reference architecture that extends the framework provided by the DHS Federal Network Security CAESARS [Continuous Asset Evaluation, Situational Awareness, and Risk Scoring] architecture. This extension enables added functionality, defines each subsystem in more detail, and further leverages security automation standards. It also extends CAESARS to allow for large implementations that need a multi-tier architecture. The goal of this document is to facilitate enterprise continuous monitoring by presenting a reference architecture that enables organizations to aggregate collected data from across a diverse set of security tools, analyze that data, perform scoring, enable user queries, and provide overall situational awareness. The architecture design is focused on enabling organizations to realize this capability by leveraging their existing security tools and thus avoiding complicated and resource intensive custom tool integration efforts."
