The Riverbed Optimization System (RiOS) that provides intermediary services for TLS must be configured to comply with the required TLS settings in NIST SP 800-52. An XCCDF Rule
The Riverbed Optimization System (RiOS) that provides intermediary services for TLS must be configured to comply with the required TLS settings in NIST SP 800-52.
Medium Severity
<VulnDiscussion>SP 800-52 provides guidance on using the most secure version and configuration of the TLS/SSL protocol. Using older unauthorized versions or incorrectly configuring protocol negotiation makes the gateway vulnerable to known and unknown attacks which exploit vulnerabilities in this protocol.
This requirement applies to TLS gateways (also known as SSL gateways) and is not applicable to VPN devices. Application protocols such as HTTPS and DNSSEC use TLS as the underlying security protocol thus are in scope for this requirement. NIS SP 800-52 provides guidance.
SP 800-52 sets TLS version 1.1 as a minimum version, thus all versions of SSL are not allowed (including for client negotiation) either on DoD-only or on public facing servers.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
