SI-04(25) Optimize Network Traffic Analysis
Control
Provide visibility into network traffic at external and key internal system interfaces to optimize the effectiveness of monitoring devices.
Discussion
Encrypted traffic, asymmetric routing architectures, capacity and latency limitations, and transitioning from older to newer technologies (e.g., IPv4 to IPv6 network protocol transition) may result in blind spots for organizations when analyzing network traffic. Collecting, decrypting, pre-processing, and distributing only relevant traffic to monitoring devices can streamline the efficiency and use of devices and optimize traffic analysis.
Assessment Objective
- visibility into network traffic at external system interfaces is provided to optimize the effectiveness of monitoring devices;
- visibility into network traffic at key internal system interfaces is provided to optimize the effectiveness of monitoring devices.
Assessment Method
Examine
System and information integrity policy
