User and Connection Management

Chairperson and Auditor user Authorization Levels are not supported in Ultra Secure Mode.

In Ultra Secure Mode (ULTRA_SECURE_MODE=YES), Users can be automatically disabled or locked out by the system when they do not log into the Collaboration Server application for a predefined period or if their login session does not meet Enhanced Security requirements. Users can be manually disabled by the administrator.

An administrator can enable a User who was disabled automatically by the system (in the Ultra Secure Mode) or manually by the administrator.

Additional security measures can be implemented in the Collaboration Server by setting the appropriate system flags. These measures control the system users, the user connections to the MCU and the user login process.

Managing system users includes:

●User types that are not supported when the Ultra Secure Mode is enabled.

●Disabling and enabling system Users.

●Renaming Users.

●Disabling inactive users.

Managing the user login process includes:

●Implementing Strong Passwords.

●Implementing password re-use / history rules.

●Defining password aging rules.

●Defining password change frequency.

●Forcing password change.
