Rethinking security with Identity Detection & Response (IDR)

IDR features the ability to detect credential theft and privilege misuse and attacks on active directory and risky entitlements that create attack paths

Gulf Business

With identity-based attacks on the rise, today’s businesses require the ability to detect when attackers exploit, misuse, or steal enterprise identities. This need is particularly true as organisations race to adopt the public cloud, and both human and non-human identities continue to increase exponentially. Given the penchant for attackers to use credentials and leverage Active Directory (AD), it is now critical to detect identity-based activity.

Identity Detection and Response (IDR) is a new security category adjacent to Endpoint Detection and Response (EDR), Extended Detection and Response (XDR), Network Detection and Response (NDR), and other detection solutions. While some might want to ask whether the industry needs yet another acronym amid cybersecurity’s seemingly endless alphabet soup, IDR fills a significant gap in the identity security landscape. IDR differentiates itself from identity protection systems in that it focuses on protecting credentials, privileges, cloud entitlements, and the systems that manage them. It represents an important step forward, marking the introduction of a new category of security tools.

Understanding today’s threats

The threat to identities is genuine, and given the damages occurring with their misuse, it should be a priority for every CISO. According to the 2021 Verizon data breach investigations report, credential data now factors into 61 per cent of all breaches. More broadly, the “human element” factor into 85 per cent of breaches, while phishing is present in 36 per cent of them. These stats highlight that attackers consistently attempt to access valid credentials and use them to move throughout networks undetected. Credential misuse has also enabled the growth of attack tactics like ransomware 2.0, with ransomware now making up 10 per cent of all breaches (double what it was in 2019).
Verizon is not the only organisation to note this shift. In a recent publication, Gartner estimated that “75 per cent of security failures will result from inadequate management of identities, access, and privileges” by 2023, up from 50 per cent in 2020. With this in mind, the need for more robust identity security is clear—especially the ability to detect suspicious activity leveraging valid account credentials.

What sets IDR apart

At its core, IDR features the ability to detect credential theft and privilege misuse and attacks on active directory and risky entitlements that create attack paths. IDR solutions are specifically about protecting identities, entitlements, and the systems that manage them. This emphasis is in stark contrast to existing identity protection tools like IAM, PAM, or IGA, which generally focus on authorisation and authentication and making sure the right people have access to the resources they need. IDR, alternatively, steps in to provide visibility to credential misuse, entitlement exposures, and privilege escalation activities from the endpoint to AD to multi-cloud environments.
Some organisations believe that they are protected if they have deployed EDR. EDR is a robust control for looking at attacks on endpoints and for collecting data for analysis. IDR solutions operate differently and work by looking for attacks targeting identities. Additionally, once an IDR solution detects an attack, it adds a layer of defense by providing fake data that redirects the attacker to a decoy. It can also automatically isolate the compromised system conducting the query. IDR solutions also assist in the incident response by collecting forensic data and gathering telemetry on the processes used during the attack.

Some IDR solutions will also manage the identity attack surface by providing an organisation with visibility to exposures that leave enterprise identities open to attack. These could be stored credentials on endpoints, AD misconfigurations that allow attackers to extract data or conduct attacks, or overly permissive entitlements in cloud environments that can give attackers access to sensitive or critical workloads and data. Reducing these exposures limits protects enterprise identities by limiting what attackers can exploit.

An increasing number of attacks are jumping from on-premises to the cloud. IDR solutions seamlessly extend to the cloud and deliver detailed entitlement visibility for identities that include users, applications, containers, serverless functions, and other assets. With so many human and non-human identities to manage, permission sprawl has become a severe issue. The widespread shift to remote working, cloud migration, and increasing adoption of DevOps practices have further elevated the need to limit the ability of attackers to obtain excessive rights or the privileges they need to move across domains.

Rethinking security with IDR

Today, identity security is central to the cybersecurity threat landscape, and the ability to detect and respond to identity-based threats is essential. While many tools intend to keep networks secure, IDR gives organisations a critical new weapon in their arsenal to find and fix credential and entitlement weaknesses and detect live attacks on a real-time basis. As modern cybercriminals attempt to exploit vulnerable credentials and entitlements to move through networks undetected, IDR solutions play a meaningful role in stopping them, whereas other tools simply cannot.
