Endpoint Detection and Response (EDR) is a type of security system that combines the capabilities of traditional Endpoint Protection Platforms (EPPs) with user and entity behavior analytics (UEBA) to detect malicious behavior on endpoint devices, thereby protecting them from attack. It works by observing and logging the activity on each endpoint device, both for file access and interactions with the network. When suspicious activities are detected, a response process is triggered which may include blocking the offending application or disabling the connection to minimize risk.
EDR works in real-time and is thus often referred to as a “detect and respond” system as it is able to detect and act on malicious behavior in near real-time. This difference is important as it can identify malicious events before the system becomes compromised. Additionally, EDR can also help in understanding the scope of an attack. This is because it is able to provide detailed information regarding which user and endpoint initiated the attack, along with the specific malicious code used.
At its core, EDR consists of an endpoint security agent that is installed on the device, and a cloud-based management console which allows security team members to have visibility and control over the endpoints. The agent continually monitors every endpoint, allowing the security team members to see what is going on within the environment, while simultaneously containing and preventing further harm.
EDR is not to be confused with a Next-Generation Antivirus (NGAV) or Advanced Threat Protection (ATP) solutions, both of which are more focused on responding to threats. As a detect and respond system, EDR has the advantage of combining both detection and remediation into one platform. This can help to reduce the need for a large number of personnel dedicated to managing the security of an organization’s endpoints.
Implementing an effective and comprehensive EDR solution can help to reduce the risk of attack and provide security teams with better visibility and control. Additionally, due to its continuous nature, EDR can also help detect many attacks that are not identified by traditional security systems. This makes it an invaluable tool in securing an organization’s endpoints and data.
