• Administrators must set up security attribute namespaces and security attributes in a tenancy before users can apply security attributes to the DB systems.
• A security attribute is effective only with appropriate policies. If a security attribute without any policies is added, all access will be denied by default, even if allowed in the Security List or NSGs.
• If you use the security attribute, the security rules for the DB system will be a union of the rules in the security attributes along with any rules in the security list and the NSGs.
• You may need to use more than one security attribute. If you're not sure, contact your network administrator.
• A maximum of 3 security attributes can be specified for a DB system.
