Enterprise Voice, Video, and Messaging Session Management Security Requirements Guide
SRG-NET-000371
The Enterprise Voice, Video, and Messaging Session Manager must be configured to protect the confidentiality and integrity of transmitted configuration files, signaling, and media streams.
The Enterprise Voice, Video, and Messaging Session Manager must be configured to protect the confidentiality and integrity of transmitted configuration files, signaling, and media streams. An XCCDF Rule
The Enterprise Voice, Video, and Messaging Session Manager must be configured to protect the confidentiality and integrity of transmitted configuration files, signaling, and media streams.
High Severity
<VulnDiscussion>Without protection of the transmitted information, confidentiality and integrity may be compromised as unprotected communications can be intercepted and either read or altered. Communication paths outside the physical protection of a controlled boundary are exposed to the possibility of interception and modification.
Voice Video protocol suites include SIP, SCCP, and H.323. Each of these protocol suites uses different methodologies for securing transmitted signaling. The H.323 protocol suite relies on the H.235 series, which describes security within H.323, including security for both signaling and media. For SIP protocol, the DOD has created the AS-SIP protocol, which provides for implementing Transport Layer Security (TLS), Multi-Level Precedence and Preemption (MLPP), reliance on Secure Real-Time Transport Protocol (SRTP) for media streams, and Differentiated Services Code Point (DSCP) for traffic management through priority packet routing. To secure SCCP, TLS must be implemented with the protocol.
Note: It is expected that this requirement be used to address each protocol individually. A separate STIG requirement for each protocol used identifying the methods to protect the confidentiality and integrity of transmitted control information (including registration files) and media streams must be produced.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
