>Control Description

Employ automated tools and mechanisms to support near real-time analysis of events.

>DoD Impact Level Requirements

No specific parameter values or requirements for this impact level.

>Discussion

Automated tools and mechanisms include host-based, network-based, transport-based, or storage-based event monitoring tools and mechanisms or security information and event management (SIEM) technologies that provide real-time analysis of alerts and notifications generated by organizational systems. Automated monitoring techniques can create unintended privacy risks because automated controls may connect to external or otherwise unrelated systems. The matching of records between these systems may create linkages with unintended consequences.

Organizations assess and document these risks in their privacy impact assessment and make determinations that are in alignment with their privacy program plan.
