Logs provide a record of events for servers, databases, applications, or security systems. They support audit, compliance measurement, trend analysis, and anomaly detection.
For privacy, log data can provide these capabilities in a privacy-context, supporting intelligence, automation, and reporting for data subject rights, privacy violations, compliance readiness, and regulatory reporting. But logs may also introduce risks if personal data is not considered.
Logs themselves can introduce privacy risk by capturing the personal information of data subjects and/or by tracking the activities of data subjects outside the bounds of specific or implied consent. Therefore, log data must be treated as any other data source in regards to privacy policies, processes, and controls.
