The Automation Controller NGINX web server must employ cryptographic mechanisms (TLS/DTLS/SSL) to prevent the unauthorized disclosure of information during transmission.
An XCCDF Rule
Description
<VulnDiscussion>Preventing the disclosure of transmitted information requires that the Automation Controller web server take measures to employ some form of cryptographic mechanism in order to protect the information during transmission. This is usually achieved through the use of Transport Layer Security (TLS). Transmission of data can take place between the web server and a large number of devices/applications external to the web server. Examples are a web client used by a user, a backend database, an audit server, or other web servers in a web cluster. If data is transmitted unencrypted, the data then becomes vulnerable to disclosure. The disclosure may reveal user identifier/password combinations, website code revealing business logic, or other user personal information.
