Combining Network Access Control (NAC) and SIEM functionality based on open source

Abstract

Security Information and Event Management (SIEM) solutions are expensive, difficult to handle, and still a further security system without interface to existing Network Access Control (NAC) or other security components of an enterprise. Thus, the research project CLEARER [2] aims at developing a security system, which extends existing NAC systems with SIEM functionality, additional analyzing methods and dynamical compliance support. This goal will only be reached by using Open Source Software (OSS). The expected result, a common security platform for attack prevention will be affordable for small and medium-sized enterprises (SME) in contrast to other vendor-based SIEM systems.
