Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) report messages must be filtered to allow hosts to join only those multicast groups that have been approved by the organization.
Low Severity
<VulnDiscussion>Real-time multicast traffic can entail multiple large flows of data. Large unicast flows tend to be fairly isolated (e.g., someone doing a file download here or there), whereas multicast can have broader impact on bandwidth consumption resulting in extreme network congestion. Hence, it is imperative that there is multicast admission control to restrict which multicast groups that hosts are allowed to join via IGMP (IPv4) or MLD (IPv6).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
