Endpoint Detection and Response, or EDR tools, are tools used to alert security teams about malicious activity in the network. Using EDR means fast investigation and containment of any malicious files discovered on endpoints. EDR solutions typically aggregate endpoint data, including all processes, files executions, communications, and user logins to discover anomalies that might indicate a threat and then respond to the threat. EDR provides automated and manual operations, designed to remove or isolate any threat from the network.
Anton Chuvakin, Gartner’s research director, coined the term “EDR” in 2013, while researching the need for more powerful malware hunting tools capable of “detecting and investigating suspicious activities (and traces of such) other problems on host/endpoints.” In short, EDR is dedicated to prevention and less focused on mitigation, a vast deviation from traditional anti-virus detection and mitigation methods.
Endpoint detection and response, or endpoint threat detection and response (ETDR), is a security solution designed to monitor the network in real-time for threat. EDR provides rule-based and automated response to threat after detecting and investigating suspicious activity on endpoints and hosts. Security teams use EDR to simplify network security processes and free up time for more productive and business-centric tasks. Primary functions of an EDR system include:
Network detection and response (NDR) is a security solution designed to provide full visibility of known, unknown and zero-day threats within your network. NDR provides centralized management and can be combined with machine learning or AI to perform analysis of network traffic and respond to threats, while enabling workflows and automation.
EDR is different from NDR in that it focuses on protecting endpoints from attack by monitoring and blocking potentially malicious traffic or files. Cyber criminals who can navigate around EDR are usually stopped by network detection and response. In short, EDR is a grass-roots view of the system, while NDR is a panoramic, aerial overview.
EDR is deployed on endpoints and designed to detect and mediate file-based malware and both trusted and untrusted applications. The investigation and mitigation functions respond to alerts and incidents automatically, simplifying the entire network security process. The global endpoint security market is expected to reach $9.51 billion by the end of 2021 and reach $15 billion by 2024. The endpoint detection and response market is characterized by:
OSSEC is an open-source and free software EDR that offers log analysis, real-time windows registry monitoring, and other EDR features. OSSEC is primarily used in large enterprises, SMBs, and governmental agencies in need of light endpoint detection and response functions. OSSEC provides
TheHive Project is a “security incident response (platform) for the masses,” drafting fast and detailed security incident reports to help inform security strategies. TheHive Project is a collaboration platform with powerful live streaming, real-time information, and task assignation. TheHive Project provides:
osQuery is released as an application under the Apache license, with querying software that increases visibility of connected devices, and is typically used by SMBs and large enterprises.
Nessus vulnerability scanner scans ports for system vulnerabilities but does not have full EDR capabilities. Nessus provides:
Snort is robust intrusion prevention software designed to analyse packet logging and real-time traffic, and a useful EDR tool for audits and threat investigations. Although, Snort doesn’t have full EDR capabilities. Snort provides:
Sangfor Endpoint Secure is a different approach to traditional EDR and NDR solutions. Endpoint Secure provides the most powerful malware and ransomware detection capabilities on the market, in addition to collaboration with Sangfor’s other security solutions, NGAF Next Generation Application Firewall, IAG secure web gateway and Cyber Command which is an NDR tool, to provide holistic response and protection.
Enterprises of all sizes use Endpoint Secure to detect and track malware, APT and other types of attacks, and respond to them in real-time with automated security functions. Finally, Endpoint Secure cloud-managed, hybrid solution, is gaining global traction and recognition in the EDR market for its scalability, ease of operation, management, and maintenance.
In 2020 there were record losses to ransomware and malware. With a ransomware attack every 11 seconds, deploying an EDR system is vital for enterprise.
