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. The perimeter defense has no oversight or control of attacks by malicious users within the network. Prevention of network breaches from within the network requires a comprehensive defense-in-depth strategy, including security all devices connecting to the network. This is accomplished by following and implementing all security guidance applicable for each node type. A fundamental step in securing each IDPS is to only enable the ports, protocols, and services required for operation. The IDPS application must not be configured to use ports, protocols or services which are prohibited by the Ports, Protocol, and Service Management (PPSM) requirements. Unneeded functions and capabilities must also be disabled.
