# COSMOS Developer's Guide

## How COSMOS Enables Authentication, Authorization, and Encryption for its Web UI

The COSMOS user interface provides the ability to attach security credentials to requests made to an MDR or non-MDR. End users can open the Properties dialog on an MDR or non-MDR from the navigation tree within the COSMOS UI. The end user can then enter a username and password. Once this is done, any request made to the MDR or non-MDR contains the associated username and password.

The COSMOS UI by default, does not encrypt the security credentials over the network. The simplest method to encrypt the security credentials is to connect to the server side component using a secure socket layer. Therefore the web server that hosts the COMOS UI data feeds and MDRs should be configured to accept HTTPS connections.
