Automation Controller must use encryption strength in accordance with the categorization of the management data during remote access management sessions.
An XCCDF Rule
Description
<VulnDiscussion>Remote management access is accomplished by leveraging common communication protocols and establishing a remote connection to the application server via a network for the purposes of managing Automation Controller. If cryptography is not used, then the session data traversing the remote connection could be intercepted and compromised. Automation Controller is accessed via standard HTTP (redirect)/HTTPS on standard ports, provided by NGINX. A self-signed certificate/key is installed by default; however, a user can provide a locally appropriate certificate and key per their organizational policy. SSL/TLS algorithm support is configured in the /etc./nginx/nginx.conf configuration file. Satisfies: SRG-APP-000014-AS-000009, SRG-APP-000142-AS-000014, SRG-APP-000172-AS-000120, SRG-APP-000441-AS-000258, SRG-APP-000442-AS-000259</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Remediation - Manual Procedure
Enable HTTPS by running the following command:
./setup.sh -e nginx_disable_https=false
The "nginx_disable_https" variable disables HTTPS traffic through NGINX, this is useful if offloading HTTPS to a load balancer.
