Identity monitoring is the continuous observation and analysis of user and system identities to detect suspicious or unauthorized activity. It involves tracking login attempts, privilege escalations, access patterns, and changes to identity configurations. This process is crucial for identifying potential security breaches or insider threats in real time, enabling prompt incident response. For instance, an identity monitoring system might flag multiple failed login attempts from an unfamiliar IP address followed by a successful login using compromised credentials. Unlike simple access logging, identity monitoring actively analyzes these events for anomalies rather than just recording them. This concept is fundamental to cybersecurity domains covered in certifications like CompTIA Security+ and CISSP.
