During which phase does Company ABC ensure information privacy and protection through an ISMS?

The phase in which Company ABC ensures information privacy and protection through an Information Security Management System (ISMS) is the discovery phase. This phase is crucial as it involves identifying and assessing the organization's information assets, understanding their value, and recognizing the potential risks and threats to those assets.

During discovery, organizations typically conduct a thorough analysis of their current information security state, including existing policies and procedures. This groundwork is essential for tailoring the ISMS to effectively address privacy and protection concerns. It establishes the foundation for what needs to be protected and the regulatory requirements relevant to the specific data involved, ensuring that all elements of the ISMS are aligned with the organization's information security objectives.

In contrast to the discovery phase, the other phases—testing, development, and deployment—focus on implementing and verifying the security measures after initial assessments and identifications have already been made. While they are important phases in the overall lifecycle of an ISMS, they do not primarily focus on the initial groundwork for ensuring information privacy and protection, which is fundamentally rooted in the discovery phase.
