Security policies (that address purpose, scope, roles, responsibilities, management commitment, and coordination among organisational entities), processes, and procedures are maintained and used to manage protection of information systems and assets.

An SDLC implementation may lead to the identification and localisation of redundancy of services
Organisational communication and data flows are mapped

The data, personnel, devices, systems, and facilities that enable the organisation to achieve business purposes are identified and managed consistent with their relative importance to organisational objectives and the organisation’s risk strategy.

Mapping data flow may lead to the identification and localisation of redundancy of services
Resources (e.g., hardware, devices, data, and software) are prioritized based on their classification, criticality, and business value
Function:
IDIdentify

ID.AMAsset Management
Subcategory:

The data, personnel, devices, systems, and facilities that enable the organisation to achieve business purposes are identified and managed consistent with their relative importance to organisational objectives and the organisation’s risk strategy.

Classify resources according to their criticality and value will enable to localise redundancy of services
