What approach is employed to restrict an attack's capability to go on while maintaining the availability of systems and services?

Containment initiatives are used to curtail the extent or consequences of an incident. The focus of containment may be on maintaining systems or services online, enabling organizations to continue operations until alternative business continuity arrangements can be established. Segmentation involves the separation of systems or services into distinct security zones, while isolation entails either complete removal from all contact or placement in small groups that are separated from the unaffected parts of the organization and systems.
