What is Identity Threat Detection and Response (ITDR)?

Identity threat detection and response (ITDR) is a cybersecurity solution that protects identities, credentials and the systems that manage them. A comprehensive ITDR solution will provide three main functionalities:

    1. Prevent complex, identity-based attacks, such as ransomware
    2. Detect identity-based attacks in real-time
    3. Enable efficient and effective response capabilities in the event of an attack

Why is ITDR important?

Analysis indicates that eight in ten (80%) of breaches are identity-driven. These modern attacks often bypass the traditional cyber kill chain by directly leveraging compromised credentials to accomplish lateral movements and launch bigger, more catastrophic attacks.

Identity-driven attacks are extremely hard to detect. When a valid user’s credentials have been compromised and an adversary is masquerading as that user, it is often very challenging to differentiate between the user’s typical behavior and that of the hacker using traditional security measures and tools. Research shows that breaches from compromised credentials take, on average, 250 days to identify when relying on traditional authentication log analysis, disparate user behavior analysis solutions and non-consolidated products and solutions.

While modern organizations have multiple identity security solutions to help prevent and detect identity-related attacks, including Microsoft Active Directory, Azure Active Directory, single sign-on (SSO), multi-factor authentication (MFA), privileged access management (PAM) and more, companies must carefully integration these tools to produce an accurate and complete view of the identity threat landscape. They must also correlate authentication events coming from a variety of managed and unmanaged endpoints, as well as any third-party service providers.

Where does AD hygiene fit into ITDR?

An organization’s Active Directory (AD) – a directory service developed by Microsoft for Windows domain networks in 1999 – is widely considered one of the weakest links in an organization’s cyber defense strategy. Built on decades-old legacy technology, AD is one of the most widely used identity stores and is still relied upon by over 90% of Fortune 1000 organizations. This makes it a prime target for adversaries to breach the network, move laterally and escalate privileges.

Any security compromise of AD undermines the entire identity infrastructure, leading to potential data leaks as well as potential system corruption/takeover or catastrophic ransomware or supply chain attacks.

A good ITDR security solution should therefore include robust AD security capabilities to enable deep, continuous, unified visibility of all users across the enterprise as well as the ability to detect and prevent malicious AD-attacks in real-time.

Considerations when selecting an ITDR solution

There are many vendors that offer ITDR solutions – though not all are created equal. It is important for companies to understand what features and functionalities to look for in a solution. Key areas to consider include:

Comprehensive coverage

    • Does the solution cover legacy and proprietary applications and tools?
    • Can the solution detect and stop modern attacks, like ransomware, in real-time?
    • Does it provide real-time, highly reliable detections by leveraging advanced analytics and AI?
    • Does it enforce risk-based conditional access based on behavior, user and device risk?

Continuous visibility

    • Does the solution offer complete and continuous visibility across a hybrid identity/multi-directory landscape?
    • Does it offer attack path visibility?
    • Does it provide deep insights into identity-based incidents in the event one occurs?

Automated classification

    • Does the solution auto-classify every identity by type: human, service, privileged?
    • Does it provide deep visibility into authentication traffic to detect and stop identity-based incidents, including lateral movement, service account misuse, malicious or suspicious behavior and protocol abuse?

End-to-end services

    • Does the vendor provide a scalable and unified platform to ensure protection as the company grows?
    • Does the provider ensure frictionless, conditional access?
    • Does the vendor offer identity protection as a service with continuous monitoring and remediation of hard-to-detect identity-based incidents?
