Question

A government organization operates and maintains several ICS environments. The categorization of one of the ICS environments led to a moderate baseline. The organization has complied a set of applicable security controls based on this categorization.

Given that this is a unique environment, which of the following should the organization do NEXT to determine if other security controls should be considered?

A. Check for any relevant or required overlays.
B. Review enhancements within the current control set.
C. Modify to a high-baseline set of controls.
D. Perform continuous monitoring.

Answer 1

To determine if other security controls should be considered, the organization should check for relevant overlays, perform continuous monitoring, and review enhancements within the current control set.

Step-by-step explanation:

To determine if other security controls should be considered for the unique ICS environment, the government organization should check for any relevant or required overlays. Overlays are additional security controls that may be necessary depending on specific requirements or regulations. By reviewing the overlays, the organization can ensure that all necessary security controls are in place.

Additionally, the organization should perform continuous monitoring to assess the effectiveness of the current security controls. Continuous monitoring allows for the identification of any gaps or vulnerabilities that may require additional security controls.

Finally, the organization should also review enhancements within the current control set. This involves regularly evaluating and updating the existing security controls to address any new threats or vulnerabilities that may arise.
