Cyber Assessment Framework mappings generated from UK Cabinet Office data.

Control ID Name Description
B4.b Secure Configuration You securely configure the network and information systems that support the operation of essential functions.
B2.c Privileged User Management You closely manage privileged user access to networks and information systems supporting the essential function.
B3.b Data in Transit You have protected the transit of data important to the operation of the essential function. This includes the transfer of data to third parties.
B5.b Design for Resilience You design the network and information systems supporting your essential function to be resilient to cyber security incidents. Systems are appropriately segregated and resource limitations are mitigated.
B4.a Secure by Design You design security into the network and information systems that support the operation of essential functions. You minimise their attack surface and ensure that the operation of the essential function should not be impacted by the exploitation of any single vulnerability.
