ITDR stands for Identity Threat Detection and Response. It is a security practice and framework designed to detect, respond to, and mitigate threats related to compromised identities within an organization's IT infrastructure. ITDR focuses on monitoring and safeguarding identity systems, such as authentication services and identity and access management (IAM) systems, from attacks aimed at abusing or exploiting user credentials and identities.
In the context of cybersecurity and infosec, ITDR typically involves the following key activities:
Threat Detection: Identifying signs of unauthorized access, credential theft, privilege escalation, or abnormal behavior in identity systems.
Incident Response: Taking immediate action when identity-related threats are detected, such as isolating compromised accounts, enforcing multi-factor authentication (MFA), or blocking malicious login attempts.
Monitoring and Logging: Continuously tracking identity-related activities (login attempts, password changes, privilege adjustments) to detect patterns indicative of attacks such as brute force, phishing, or account takeover.
Remediation: Ensuring proper containment and recovery from identity-related security incidents, such as resetting passwords, revoking access, or applying security patches.
ITDR has become increasingly important due to the rise of identity-based attacks like phishing, credential stuffing, and Active Directory exploits, which target the identity layer of security. By focusing on identities, ITDR helps organizations protect against these types of attacks more effectively.
