Identity Threat Detection and Response

ITDR

Identity Threat Detection and Response (ITDR) is an emerging cybersecurity discipline focused on detecting, analyzing, and responding to attacks that target identity infrastructure — such as credential theft, pass-the-hash, Golden Ticket attacks, and identity provider compromise.

⚙️ How Does It Work?

ITDR tools monitor identity systems (AD, Entra ID, Okta) for indicators of compromise: unusual privilege escalation, lateral movement, impossible travel, dormant account activation, and changes to sensitive groups. Automated or manual response actions contain the threat.

📍 Where Is It Used?

SOC operations, enterprise identity infrastructure — any organization where identity compromise is a primary attack vector (which is now virtually everyone).

💡 Real-World Example

An ITDR platform detects that a service account has suddenly been added to the Domain Admins group at 3 AM — a classic privilege escalation indicator. It automatically disables the account, alerts the SOC, and begins forensic logging, containing the attack before any damage is done.
