Define a set of security providers in Sybase Control Center to protect domain resources, according to the specific security requirements of the domain. Create a security configuration, then map it to the desired domain.
A security configuration determines the scope of data access and security. A user must be part of the security repository used by the configured security providers to access any resources (that is, either a Sybase Control Center administration feature or a data set from a back-end data source) on a domain. See Security Configurations in the Security guide.
