Common Alarm Service (CAS) Security
Security for the CAS is administered by the Access Control Service (ACS). As with other CygNet services, security is set on an application and event basis. The application name of the CAS is defined in the service configuration file using the keyword ACS_APPLICATION. The default is “CAS.” The security events are listed in the CAS Events table below.
The following tables provide details about CAS security settings. See also Security.
