The application server must employ approved cryptographic mechanisms to prevent unauthorized disclosure of information and/or detect changes to information during transmission.

Description

<VulnDiscussion>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. TLS must be enabled and non-FIPS-approved SSL versions must be disabled. NIST SP 800-52 specifies the preferred configurations for government systems.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
