(b) Authentication and validation. The CMS provider gateway must authenticate interactions with the Federal alert gateway, and validate Alert Message integrity and parameters. The CMS provider gateway must provide an error message immediately to the Federal alert gateway if a validation fails.
(c) Security. The CMS provider gateway must support standardized IP-based security mechanisms such as a firewall, and support the defined CMAS “C” interface and associated protocols between the Federal alert gateway and the CMS provider gateway.
