Definition
Insider Risk and Discovery refers to the identification and management of potential security threats originating from within an organization, such as employees, contractors, or partners who have legitimate access to systems and data. This involves monitoring user activity, data access patterns, and system behaviors to detect anomalies that could indicate malicious intent or accidental data leakage. Understanding and mitigating insider risks is crucial for protecting sensitive information, maintaining operational integrity, and preventing financial or reputational damage. For instance, a company might use data loss prevention tools to alert administrators when an employee attempts to copy a large volume of customer data to a personal USB drive. This differs from external threats, which originate from outside the organization's trusted network perimeter. Concepts related to insider risk and discovery are frequently assessed on certifications like CompTIA Security+, CySA+, and CISSP.
