The network element must generate unique session identifiers with organization-defined randomness requirements.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity

Description
Peering neighbors must have a level of trust with each other since information being shared is used to provide network services, connectivity, and optimized routing. Corrupted or erroneous information shared between network elements can disrupt network operations by creating non-optimized forwarding of traffic and network outages. Identifying source and destination addresses for information flows within the network allows forensic reconstruction of events when required, and increases policy compliance by attributing policy violations to specific individuals. Means to enforce this enhancement include ensuring the network element authenticates the source involved in sending the information. Unique session identifier must also be used to reduce the risk of session hi-jacking. The greater the randomization of the session identifier, the more difficult to guess or anticipate.
