A description is given of how the group security model provides access control in knowledge base systems and supports the security requirements of data from a variety of sources in a comprehensive environmental information system. An overview of problems encountered when designing access control in knowledge bases is given. The access control requirements of an environmental information system are reviewed. The group security model, which provides for the specification of access criteria for groups and tasks and which can provide multilevel security for any entity of information in a knowledge base system, is then described. The implementation of the group security model in ConceptBase, a knowledge base management system, is considered. An example scenario from an environmental information system under ConceptBase is given
