Identity threat detection and response: are your controls keeping up?

TL;DR: Identity Threat Detection and Response loses value when IAM programmes depend on backward-looking logs, because attackers move faster than analysts can sift terabytes of event data, according to Imprivata. Real-time behavioral context, not event accumulation, is what turns identity signals into usable detection and response.

NHIMG editorial — based on content published by Imprivata: Identity threat detection and response beyond logs

By the numbers:

• 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools.
• When AWS credentials are exposed publicly, attackers attempt access within an average of 17 minutes and as quickly as 9 minutes in some cases.
• Only 5.7% of organisations have full visibility into their service accounts.

Questions worth separating out

Q: How should security teams implement identity threat detection without relying on logs alone?

A: Use logs as input, not as the control itself.

Q: Why do logs fall short for identity threat response?

A: Logs are backward-looking and often too slow for attacks that unfold in minutes.

Q: When should organisations prioritise behavioral analytics over more logging?

A: When identity abuse can move faster than human triage, behavioral analytics should take priority.

Practitioner guidance

• Replace log-only detection with live behavioral correlation Tie authentication, access, device, and session signals together so the system can identify abnormal patterns before the session ends.
• Define baselines for high-value identities Establish normal access patterns for privileged users, service accounts, and other sensitive identities, then alert on deviations in geography, device posture, and resource sequence.
• Automate step-up response for risky behavior Trigger MFA, session restriction, or access blocking when behavior crosses a defined threshold.

• How its real-time identity graph is used to connect users, devices, and behaviors during active sessions
• How behavior-driven detection is positioned inside an enterprise access management and ITDR workflow
• How the platform handles scale without relying on manual log review
• How proactive access responses are triggered when a signal crosses a defined threshold
