Identity Threat Detection and Response (ITDR)
ITDR is a security capability that monitors identity systems and user behavior to detect compromises, anomalies, and attacks. It combines threat detection with automated or guided response to stop identity-based attacks before they cause damage.
# WHAT TEAMS RUN INTO
- —
ITDR generates alert fatigue. Real compromises mixed with false positives create alert storms. Analysts cannot investigate every alert, so real attacks hide in the noise.
- —
ITDR response is limited by architecture. If the identity system is the attacker's target, ITDR detection might come from the identity system itself — the attacker is potentially inside the detection system.
- —
ITDR blindness during attacks. ITDR looks at logs and signals from identity systems, but if an attacker compromises the logging infrastructure or disables logging, ITDR becomes blind.
# WHY IT MATTERS
ITDR is the system that catches identity attacks after they start but before they cause catastrophic damage. Without ITDR, identity compromises can run for weeks undetected. With ITDR, most attacks are caught within hours. ITDR cannot prevent attacks, but it can make attacks expensive and risky by shortening dwell time and limiting damage.
