Discussion

Connectors are how Tomcat receives requests over a network port, passes them to hosted web applications via HTTP or AJP, and then sends the results back to the requestor. Cryptographic ciphers are associated with the connector to create a secured connector. To ensure encryption strength is adequately maintained, the ciphers used must be FIPS 140-2-validated. The FIPS-validated crypto libraries are not provided by Tomcat; they are included as part of the Java instance and the underlying Operating System. The STIG checks to ensure the FIPSMode setting is enabled for the connector and also checks the logs for FIPS errors, which indicates FIPS non-compliance at the OS or Java layers. The administrator is responsible for ensuring the OS and Java instance selected for the Tomcat installation provide and enable these FIPS modules so Tomcat can be configured to use them. Satisfies: SRG-APP-000224-AS-000152, SRG-APP-000428-AS-000265, SRG-APP-000429-AS-000157, SRG-APP-000439-AS-000274, SRG-APP-000440-AS-000167

Check Content

From the Tomcat server console, run the following two commands to verify Tomcat server is configured to use FIPS:

sudo grep -i fipsmode $CATALINA_BASE/conf/server.xml

sudo grep -i fipsmode $CATALINA_BASE/logs/catalina.out

If server.xml  does not contain FIPSMode="on", or if catalina.out contains the error "failed to set property[FIPSMODE] to [on]", this is a finding.
