🌍 Day 32 — Control #31: Identity Threat Detection & Response (ITDR) Validation

Theme: Attackers don’t break your systems — they log in.

Identity is now the #1 attack surface.
And yet, most organizations still treat it like a login feature, not a security layer.

Modern attacks don’t start with malware.
They start with:

🔸 Stolen tokens
🔸 Compromised credentials
🔸 MFA fatigue
🔸 Session hijacks
🔸 Privilege escalation
🔸 OAuth abuse
🔸 Rogue service accounts
🔸 Identity drift
🔸 Shadow admin permissions

Attackers don’t try to “break in” anymore.
They simply authenticate in.

This is why Identity Threat Detection & Response (ITDR)
is no longer optional.
It is the center of modern security.

Today’s control test:

“Validate ITDR coverage across identities, sessions, tokens, access paths, privilege changes, and risky sign-in behavior.”

Because detection without identity context
is not detection —
it’s noise.

🧠 Control Testing Checklist

Identity Telemetry

✅ Monitor anomalous sign-ins (geo-velocity, TOR, impossible travel)
✅ Detect risky OAuth consent grants
✅ Track MFA fatigue & push bombing attempts

Identity Integrity

✅ Validate token replay detection
✅ Check privileged role changes
✅ Identify dormant admin accounts
✅ Monitor service account behavior

Identity Threat Response

✅ Automated session revocation for abnormal activity
✅ Automated MFA challenge for risk signals
✅ Enforcement of Conditional Access / Zero Trust rules

Identity Hardening

✅ Validate JIT access
✅ Validate identity lifecycle governance
✅ Validate strong session binding

💡 Core Insight

Your firewalls can’t protect you if attackers walk in through identity.
Identity is the new perimeter. ITDR is the new SOC.
