With the rapid evolution of cyber threats, EDR solutions are also evolving. This article will explore EDR’s future through the lens of Managed Security Operations Centers (MSOCs). We’ll understand how EDR will adapt to address emerging challenges.

What is Endpoint Detection and Response?

Endpoint Detection and Response, or endpoint detection and threat response (EDTR), is an endpoint security solution that constantly monitors end-user devices to detect and respond to cyber threats like ransomware and malware.

EDR, the term coined by Gartner’s Anton Chuvakin, is a solution that “records and stores endpoint-system-level behaviors, uses various data analytics techniques to detect suspicious system behavior, provides contextual information, blocks malicious activity, and provides remediation suggestions to restore affected systems.”

EDR security solutions help security teams monitor endpoints and workloads for hidden threats. By recording activities and events, EDR brings improved visibility, allowing security professionals to uncover incidents that traditional methods might miss.

For comprehensive defense, an EDR solution should be a well-armed investigator. It should provide advanced threat detection, investigation, and response capabilities. This includes features like incident data search and triage, validation of suspicious activities, proactive threat hunting, and the power to contain malicious activity.

Five Features of EDR Solutions

EDR features that must be known include automated remediation, behavioral analytics, vulnerability management, threat intelligence integrations, and device monitoring and control.

Threat Intelligence Feed Integration

Threat intelligence integrations are required, as they include threats, indicators of compromise (IoC), and more, so the security team can assess a wide range of behaviors and threats. EDR tools combine with third-party threat intel solutions so that security teams have ample information to keep the business on top of vulnerabilities.

Automated Remediation

Security teams configure automatic threat remediation by setting remediation rules in advance or using prebuilt ones. A particular action on an endpoint prompts a predefined remediation policy without human interaction. The EDR tool sets remediation in motion. Automation is helpful because it lessens manual remediation work for security admins. It’s a particularly good feature for small security teams.

Vulnerability Monitoring & Management

EDR solutions constantly monitor endpoints, warning security teams when the software discovers vulnerabilities that could be exploited. These include outdated operating systems, backdoors, and misconfigurations. Automated searches for vulnerabilities are more efficient and allow IT and security teams to catch vulnerabilities quickly and spend time on other tasks.

Behavioral Detection

EDR leverages the power of machine learning technology to analyze a vast ocean of user and device behaviors. This allows it to spot anomalies that might signal a cybercriminal at work or a sneaky malware infection. Unlike manual methods, behavioral detection sifts through massive amounts of data to automatically pinpoint potential threats, saving security teams precious time. It’s a game-changer, especially when facing never-before-seen attacks (zero-day attacks).

Device Control

EDR solutions screen USB devices and other direct-attached storage for malicious behavior. Threat actors use USB and flash drives to infect systems with malware, and employees often plug unknown storage devices into computers without knowing what’s on them. EDR tools allow admins to set strict policies for device use and determine when to give remote access permissions to USB devices.

Key Functions of Endpoint Detection and Response (EDR)

Exposes Hidden Attackers

EDR technology combines complete visibility across all endpoints with IOAs and applies behavioral analytics, which analyzes billions of events in real time to detect traces of suspicious behavior automatically.

Understanding individual events as part of a broader sequence allows the EDR tool to apply security logic derived from Intelligence. The EDR tool will identify the activity as malicious and automatically send a detection alert if the sequence of events matches a known IOA.

Incorporates Threat Intelligence

Integration with cyber threat intelligence provides faster detection of the activities, tactics, techniques, and procedures (TTPs) identified as malicious. This delivers contextualized information that includes attribution where relevant, offering details on the rival and any related information known about the attack.

Managed Threat Hunting for Proactive Defense

EDR empowers your security team to become cyber detectives. They can proactively hunt for threats lurking within your environment, investigate suspicious activity, and advise on the necessary action. This collaborative approach ensures threats are identified and contained before they escalate into full-blown breaches.

Real-time and Historical Visibility Offering

Think of EDR as a security DVR for your endpoints. It continuously records critical events, like process creation, driver loading, and network connections, clearly showing what’s happening on your devices. This unmatched visibility helps uncover hidden threats that might have bypassed traditional security measures.

Accelerates Investigations

Endpoint detection and response can increase the speed of investigation and, ultimately, remediation because the information gathered from your endpoints is stored in the cloud, which has an architecture based on a situational model.

Using a massive, powerful graph database, the model tracks all the relationships and contacts between each endpoint event. This database provides details and context rapidly and at scale for both historical and real-time data, enabling security teams to investigate incidents quickly.

This speed and level of visibility, combined with integrated, contextualized intelligence, provides the information needed to understand the data thoroughly. This enables security teams to effectively track even the most sophisticated attacks and promptly uncover incidents, triage, validate and prioritize them, leading to faster and more precise remediation.
