Data Anomalies

The following anomalies represent unusual access to files and records within your Sanctioned Service. They may indicate malicious users inside the organization, users who have access to a lot of data they are not authorized for or users who have access to a lot of data that may be at a risk of loss. Insider Threats anomalies may also indicate users accessing an unusual number of files for a special project, or a change in responsibilities. Data anomalies work in concert with Administrative Anomalies and Access Anomalies to determine threats. These anomalies are all based on established activity thresholds and are mapped to specific service actions.
