All changes in this version
first version loaded SI High baseline part of SI-4

Title

Visibility of Encrypted Communications

Control

Make provisions so that [Assignment: encrypted communications traffic] is visible to [Assignment: system monitoring tools and mechanisms].

Discussion

Organizations balance the need to encrypt communications traffic to protect data confidentiality with the need to maintain visibility into such traffic from a monitoring perspective. Organizations determine whether the visibility requirement applies to internal encrypted traffic, encrypted traffic intended for external destinations, or a subset of the traffic types.

Parameters

si-04.10_odp.01: encrypted communications traffic
si-04.10_odp.02: system monitoring tools and mechanisms

Assessment objective

SI-04(10) provisions are made so that [Assignment: encrypted communications traffic] is visible to [Assignment: system monitoring tools and mechanisms].
