Identity Threat Detection and Response (ITDR) is a set of tools and practices designed to defend against cyberattacks targeting user identities and Identity and Access Management (IAM) infrastructure. ITDR enhances other security systems like Endpoint Detection and Response (EDR), Extended Detection and Response (XDR), Network Detection and Response (NDR), and Privileged Access Management (PAM).
Popularized by Gartner in 2022, ITDR offers threat detection, defense mechanisms, and incident response capabilities, playing a key role in a defense-in-depth security strategy.
Importance of ITDR
The move to cloud computing and the rise of remote work has made identity management a critical task. With identity being the new perimeter in IT and cybersecurity, bad actors increasingly target identity-related vulnerabilities. According to the Identity Defined Security Alliance, 90% of organizations experienced identity-related incidents in the last year, highlighting the need for ITDR systems.
How ITDR Works
ITDR systems rely on artificial intelligence (AI), machine learning (ML), and automation to:
- Centralize identity visibility and control.
- Monitor user identities and permissions.
- Detect suspicious activity in authentication processes.
- Implement least privilege principles.
- Initiate defensive measures and incident investigation when a threat is identified.
Identity-Based Vulnerabilities
Organizations face several identity-based attacks, including:
- Unmanaged identities: Identities missed by security tools.
- Misconfigured identities: Incorrect configurations that allow unauthorized access.
- Exposed identities: Stolen or compromised credentials used in phishing or social engineering attacks.
Features of ITDR Tools
ITDR tools provide the following features:
- Identity discovery and risk scoring.
- Real-time monitoring and alerts.
- User and entity behavior analytics (UEBA).
- Attack path analysis and remediation.
- Integration with SIEM and SOAR platforms.
- Automated incident response.
IAM vs. ITDR
While IAM handles identity management and access permissions, ITDR monitors and provides oversight for identity-related processes, ensuring enhanced protection against threats.
Choosing and Implementing ITDR
To select the right ITDR tool, organizations should consider their current and future IT environments, identity complexities, and evolving threat landscapes. ITDR solutions must be integrated into the overall security strategy to effectively protect identities and ensure smooth operations.
