Explanation
An analysis of known threats is the best way for an organization to gain visibility into its exposure to privacy-related vulnerabilities because it helps identify the sources, methods and impacts of potential privacy breaches and assess the effectiveness of existing controls. A data loss prevention (DLP) solution, a review of historical privacy incidents and a monitoring of inbound and outbound communications are useful tools for detecting and preventing privacy violations, but they do not provide a comprehensive view of the organization's privacy risk posture.
