Description
Use of self-signed certificates creates a lack of integrity and invalidates the certificate based authentication trust model. Certificates used by production systems must be issued/signed by a trusted Root CA and cannot be self-signed. For systems that communicate with industry partners, the DoD ECA program supports the issuance of DoD-approved certificates to industry partners. For information on the DoD ECA program, refer to the DoD PKI office. Links to their site are available on https://public.cyber.mil.

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 -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.

Fix Text (F-24655r426427_fix)
Obtain and install the DoD PKI CA certificate bundles by accessing the DoD PKI office website at https://cyber.mil/pki-pke. Download the certificate bundles and then use certificate management utilities such as keytool or openssl to import the DoD CA certificates into the trust store.
