Connectors must be secured.

An XCCDF Rule

Description

<VulnDiscussion>The unencrypted HTTP protocol does not protect data from interception or alteration which can subject users to eavesdropping, tracking, and the modification of received data. To secure an HTTP connector, both the secure and scheme flags must be set.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

From the Tomcat server as a privileged user, edit the server.xml file.

sudo nano $CATALINA_BASE/conf/server.xml. 

Locate each <Connector/> element which is lacking a secure setting.  
EXAMPLE Connector:
<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="443" />

Set or add scheme="https" and secure="true" for each HTTP connector element.

EXAMPLE:
<Connector port="443" protocol="org.apache.coyote.http11.Http11NioProtocol" SSLEnabled="true"
    maxThreads="150" scheme="https" secure="true".../>

Save the server.xml file and restart Tomcat:
sudo systemctl restart tomcat
sudo systemctl reload-daemon

Connectors must be secured.
