Multifactor certificate-based tokens (CAC) must be used when accessing the management interface.

An XCCDF Rule

Description

Password authentication does not provide sufficient security control when accessing a management interface. DOD has specified that a CAC will be used when authenticating and passwords will only be used when CAC authentication is not a plausible solution. Tomcat provides the ability to do certificate based authentication and client authentication; therefore, the Tomcat server must be configured to use CAC.

Remediation Templates

From the Tomcat server as a privileged user, edit the $CATALINA_BASE/webapps/manager/WEB-INF/web.xml file and modify the auth-method for the manager application security constraint.

sudo nano $CATALINA_BASE/webapps/manager/WEB-INF/web.xml

Locate <auth-method> contained within the <login-config> section, modify <auth-method> to specify CLIENT-CERT. 
EXAMPLE:
<auth-method>CLIENT-CERT</auth-method>

In addition, the connector used for accessing the manager application must be configured to require client authentication by setting clientAuth="true" and the manager application roles must be configured in the LDAP server.

Restart the Tomcat server:
sudo systemctl restart tomcat
