SECURE COMPARTMENTED MODE KNOWLEDGE MANAGEMENT PORTAL

摘要

A layered defence-in-depth knowledge-based data management comprises a reception zone (12) for authenticating a user for access to the system and an operations zone (14) for adjudicating on a user level access to data objects stored in the system database. In addition, the data management comprises a security zone (16) for issuing certificates of accessibility for defined users and a screening zone (10) to interrogate data packets during processing thereof. The first line of defence is firewall protection and packet filtering preceding the reception zone.
