What is Endpoint Detection and Response (EDR)?

7/20/2019

 
Pretty much are security-savvy companies uses EDR Tools like CrowdStrike, Carbon Black, Sentinel One, Endgame, etc. They are host-based continuous monitoring tools. They are primarily used for Anomaly Detection, Threat Hunting, and Incident Response Support.  Agents are deployed over a large volume of endpoints hosts, and all the activity is sent to a centralized database. 
What can you do with the data from the EDR Tool?
  • Historical Searching, Scoping, and Remediation.
  • Real-time visibility
  • Pattern Analysis and IOC matching 

All the data can also be sent to SIEM Application like Splunk, Humio, or ELK Stack. Choice of the free text search depends on a budget of the team. EDR tools are great and offer visibility across the organization. Visibility is critical during an event of intrusion.

One key thing to remember is EDR is not a forensic tool. It'll not collect the complete data set. EDR tools are Proactive, and Forensic tools are Reactive. 
​

If you wish to learn more about the EDR and SIEM Application.Lima Charlie(https://www.limacharlie.io/), an EDR Tool, offers two free agents, and Humio Cloud a SIEM application provides a free tier (https://cloud.humio.com/).
