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. To prevent network breaches from within is dependent on implementing a comprehensive defense-in-depth strategy including securing each device connected to it. 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 only enable the ports, protocols, and services required for operation.

Check Text ( C-SRG-NET-000132-NDM-000090_chk )
Compare enabled SNMP with the Ports, Protocol, and Service Management (PPSM) requirements. If ports, protocols, and/or services are not disabled or restricted as required by the PPSM, this is a finding.

Fix Text (F-SRG-NET-000132-NDM-000090_fix)
Disable or restrict SNMP as required by the PPSM.
