ITDR Essentials: Determining Your Needs and Selecting the Right Solution

Identity theft is a concern for everyone living in the digital age. By stealing someone's identity, a criminal can gain access to their credit cards and financial accounts or apply for credit using the victim's identity. The compromise of your identity can lead to numerous troubling circumstances.

Cybercriminals have learned to leverage identity theft to access vast amounts of personal and sensitive information within digital enterprises. The strategy is straightforward: gain access to a privileged account within a digital organization and use that privilege to compromise data in some way.

The principle of attacks is simple, and defending against these attacks is equally straightforward in principle. You must protect your systems from identity based attacks such as compromised accounts, credential stuffing, password leaks, phishing, and insider threats.

What is ITDR?

Identity Threat Detection and Response (ITDR) is a cybersecurity framework designed to detect, investigate, and respond to threats targeting user identities within an organization. ITDR solutions focus on identifying suspicious activities, unauthorized access attempts, and potential identity breaches by continuously monitoring identity-related events and behaviors. In any attack scenario, time is of the essence. By leveraging advanced analytics, machine learning, and behavioral analysis, ITDR systems can proactively alert security teams to identity-based threats. Again, the premise is simple. By reducing the Mean time to Detection (MTTD) you can reduce the Mean Time to Response and prevent data breaches and other types of attacks that can disrupt your business.

Gartner describes ITDR as a collection of tools and best practices to protect identity systems. So foundational is this objective that Gartner identified the task of protecting your access management infrastructure using ITDR technology as a top trend for 2022. Improving the authentication process alone is no longer enough. According to Gartner, ITDR tools can help protect identity systems, detect when they are compromised, and enable efficient remediation.

Why is ITDR Important?

You don't have to work in cybersecurity, or even the IT field, to know that cyberattacks are increasing. Phishing scams are not only prevalent to anyone with an email address, but their scams are also continually revolving to deceive users into providing sensitive information, such as login credentials, through fake emails or websites. With the help of AI, phishing scams look very authentic today and social engineering attacks have grown quite elaborate today. Credential stuffing attacks have also become very common with all the millions of compromised credentials floating around the dark web. A common thread among all these attacks is their focus on exploiting identities.

At the same time, enterprises are pushing the limit of identity-based security with the recent shift to remote and hybrid work. Visibility is now more important than ever as employees, contract workers and third party vendors access corporate networks from unknown locations. The task of ensuring access to legitimate users only is highly challenging. Simultaneously, regulatory compliance requirements have become more stringent over the years when it comes to identity management and security. In summary, ITDR is the modern day solution to combat today's ever expanding number of identity based threats.

ITDR vs. EDR

There are a lot of cybersecurity tools, technologies and acronyms out there and keeping them straight can be confusing. There is a lot of talk about ITDR and EDR (Endpoint Detection and Response) these days, and while they complement each other in providing comprehensive cybersecurity protection, they differ in their approaches. ITDR is identity-oriented, focusing on user identities and access management, whereas EDR is focused on endpoints, such as laptops, desktops, and servers. An EDIR captures endpoint-specific data to identify and respond to threats at the device level. Should a threat actor attempt to gain access to a network through an endpoint device, it is the job of an EDR solution to detect that activity and either remediate it and/or alert a security team. When it comes to identity related threats, an ITDR solution is essential for safeguarding your organization.

ITDR Facts and Trends

With the sophistication of today's cyberattacks and the ease with which they can be executed, it is clear that traditional reactive security approaches are no longer sufficient. ITDR provides the proactive monitoring and threat detection capabilities that organizations need today to ensure that their identities are not being compromised. Beyond a proactive stance, organizations are increasingly recognizing the necessity of adopting a zero-trust approach to security, where privileged access is continuously verified at every stage.

It is also obvious that we have reached the capacity of human intervention security. Hybrid networks are vast and stretch the capacity of human oversight. Modern ITDR solutions leverage AI and ML to detect anomalies and potential threats automatically and can pick out suspicious behavior that could indicate a security risk.

While the need for identity threat detection security grows more critical, it is also growing more challenging to maintain. The dynamic nature of modern workplaces means frequent onboarding, offboarding and role changes. Many organizations suffer from a lack of visibility across multi-cloud environments and complex hybrid architectures. And then there is the fact that threat actors are becoming more adept at targeting and exploiting vulnerabilities in authentication processes, password policies, and access controls.

What to Look for in an ITDR Solution

We've established that implementing an ITDR solution is critical in today's high-threat environment, but what makes a good ITDR solution? What are the must-have components to prevent identity exploitation and compromise? Below are some key features that any modern ITDR solution should include:

• Strong preventative controls and robust identity discovery capabilities to identify and catalog all identities, both human and non-human, across the organization's network.
• Risk prioritization that enables the system to evaluate and rank potential vulnerabilities and threats based on their impact.
• Real-time operation to detect and prevent malicious access attempts before they become actual threats.
• Automated remediation capabilities that allow the system to take immediate action to mitigate risks without requiring manual intervention.
• Comprehensive and continuous visibility that provides real-time insights into identity-related activities and potential risks across the entire network.
• It should provide end-to-end services that include threat detection and response, as well as identity governance, access management, and compliance reporting.
