A company is migrating to the cloud and needs to implement a security policy. Which of the following should the company implement?

A redundancy strategy focuses on duplicating components to prevent single points of failure and ensure high availability, which is a specific tactic that contributes to a broader disaster recovery plan, not the overarching security policy implementation itself.

An integration strategy outlines how different cloud services or existing on-premises systems will communicate and function together, which is part of migration but not a primary security policy implementation.

A disaster recovery strategy is a cornerstone of a comprehensive security policy, providing the framework and procedures to restore IT systems and data after disruptive events, including security incidents, to maintain critical business operations and ensure data integrity and availability in the cloud.

A patching strategy is an operational security control focused on applying updates to mitigate vulnerabilities, which is important but represents only one aspect of a holistic security policy, rather than the complete strategy for implementing it during a cloud migration.
