The DataPower Gateway providing encryption intermediary services must implement NIST FIPS-validated cryptography for digital signatures.
An XCCDF Rule
Description
<VulnDiscussion>Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect data. The network element must implement cryptographic modules adhering to the higher standards approved by the federal government since this provides assurance they have been tested and validated. This requirement applies only to ALGs that provide encryption intermediary services (e.g., HTTPS, TLS, or DNSSEC).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

The privileged user will apply the following tasks:
From the DataPower command line, enter "use-fips on" to configure the network device to generate unique session identifiers using a FIPS 140-2 approved random number generator. From the web interface, in the default domain, use "Set Cryptographic Mode" (Administration >> Miscellaneous >> Crypto Tools, Set Cryptographic Mode tab) to set the appliance to "FIPS 140-2 Level 1" mode.
The privileged use will add a Verify action to the appropriate processing policy in the application domain (non-default domain). This action will check that only NIST SP800-131a approved digital signatures will be used.
