Discussion

Class 3 PKI certificates are used for servers and software signing rather than for identifying individuals. Class 4 certificates are used for business-to-business transactions. Utilizing unapproved certificates not issued or approved by DoD or CNS creates an integrity risk. The application server must utilize approved DoD or CNS Class 3 or Class 4 certificates for software signing and business-to-business transactions.

Check Content

For the systemd Ubuntu OS, check the tomcat.service file to read the content of the JAVA_OPTS environment variable setting.

sudo cat /etc/systemd/system/tomcat.service |grep -i truststore

EXAMPLE output:
set JAVA_OPTS="-Djavax.net.ssl.trustStore=/path/to/truststore" "-Djavax.net.ssl.trustStorePassword=************"

If the variable is not set, use the default location command below. If the variable is set, use the alternate location command below and include the path and truststore file. 

-Default location:
keytool -list -cacerts -v | grep -i issuer

-Alternate location:
keytool -list -keystore <location of trust store file> -v |grep -i issuer

If there are no CA certificates issued by a Certificate Authority (CA) that is part of the DoD PKI/PKE, this is a finding.
