Protection of call detail records data in federal telecommunications

Abstract

Techniques for protection of the call detail records (CDR) in US federal government telecommunications systems, such as the FTS2000 and agency PABXs, are identified. CDR data flow, its use in telecommunication, and its protection requirements are described. Descriptions of threats and countermeasures are provided. Recommendations for handling and protection of the CDR database are made for the following organizations: FTS2000 contractor billing, FTS2000 contractor network engineering, Service Oversight Center, and user agencies.<>
