Description
A compromised network element introduces risk to the entire network infrastructure as well as data resources that are accessible via the network. The perimeter defense has no oversight or control of attacks by malicious users within the network. Preventing network breaches from within is dependent on implementing a comprehensive defense-in-depth strategy including securing each device connected to the network. This is accomplished by following and implementing all security guidance applicable for each node type. A fundamental step in securing each network element is to enable the capabilities required for operation.

Check Text ( C-SRG-NET-000132-RTR-000075_chk )
Review the router configuration to ensure that IGMP is restricted to the boundary restrictions referenced in the PPSM CAL. If IGMP is not restricted to the boundary restrictions referenced in the PPSM CAL, this is a finding.

Fix Text (F-SRG-NET-000132-RTR-000075_fix)
Configure the router to enforce IGMP boundary restrictions as noted by the PPSM CAL.
