The paper presents a model of a secure collaborative application for conducting real-time electronic meetings from remote locations. The application consists of a set of tools, enabling common meeting tasks to be accomplished. The tools can be enhanced with security services at will. The security architecture comprises the standardized communication security services as well as the "group oriented" security services which we defined earlier. Such security architecture is especially suitable for enterprises with a defined internal organizational policy, which has to be supported and enforced by adequate security mechanisms.
