O112-C1-019700 - The DBMS must employ cryptographic mechanisms preventing the unauthorized disclosure of information during transmission unless the transmitted data is otherwise protected by alternative physical measures - SQLNET.CRYPTO_CHECKSUM_CLIENT
Preventing the disclosure of transmitted information requires that applications take measures to employ some form of cryptographic mechanism in order to protect the information during transmission. This is usually achieved through the use of Transport Layer Security (TLS), SSL VPN, or IPSEC tunnel. Alternative physical protection measures include Protected Distribution Systems (PDS). PDS are used to transmit unencrypted classified NSI through an area of lesser classification or control. Inasmuch as the classified NSI is unencrypted, the PDS must provide adequate electrical, electromagnetic, and physical safeguards to deter exploitation. Refer to NSTSSI No. 7003 for additional details on a PDS. Information in transmission is particularly vulnerable to attack. If the DBMS does not employ cryptographic mechanisms preventing unauthorized disclosure of information during transit, the information may be compromised.
Configure DBMS and/or operating system to use cryptographic mechanisms to prevent unauthorized disclosure of information during transmission where physical measures are not being utilized.
