Security

Access to the Portal is provided to users on the Internet, as well as to internal network users. The only connection permitted from the Internet is to the proxy web server. The only connection permitted to the Portal application server is from the proxy web server. All external and internal access to the Portal is only permitted through the proxy web server.

Authentication

All authentication is provided by DENR's existing single-sign-on authentication system (CAS), which is integrated with NCID via an Oracle Access Manager WebGate. The Portal itself is also integrated with NCID via web services, which is used to synchronize all user information with NCID, once successful authorization has occurred. All external and internal access to the CAS server is provided through the proxy web server. The only connection to the CAS server that is permitted, is from the proxy web server.

Client Access

All Portal functionality is accessed via a web browser. The design theme and the Portal functionality is rigorously tested and certified for all of the most widely used browsers – Microsoft Internet Explorer, Google Chrome, Mozilla Firefox, and Apple Safari – which, in total, account for over 98% of all browsers in use worldwide.

Database

All Portal settings and data – configuration, users, websites, authorities, pages, layouts, content, etc. – are stored in DENR's existing enterprise Oracle database server. The only connection permitted to the database server is from the Portal application server.
