Title

The Tomcat server must employ approved cryptographic mechanisms to prevent unauthorized disclosure of information and/or detect changes to information during transmission. (Cat II impact)

Discussion

Preventing the disclosure or modification of transmitted information requires that application servers take measures to employ approved cryptography in order to protect the information during transmission over the network. This is usually achieved through the use of Transport Layer Security (TLS), SSL VPN, or IPSec tunnel. If data in transit is unencrypted, it is vulnerable to disclosure and modification. If approved cryptographic algorithms are not used, encryption strength cannot be assured. FIPS 140-2 approved TLS versions include TLS V1.0 or greater. TLS must be enabled and non-FIPS-approved SSL versions must be disabled. NIST SP 800-52 specifies the preferred configurations for government systems.

Check Content

The Tomcat server must use SSL in order to maintain the confidentiality and integrity of information during preperation for transmission. Review the server.xml configuration file and check if the “SSL HTTP/1.1 Connector” entry is uncommented. If the “SSL HTTP/1.1 Connector” entry is commented out or does not exist., this is a finding.

Fix Text

Configure the application server to use AES 128 or AES 256 encryption for data in transit.
