When it comes to threat detection, the job of the security operations center (SOC) analyst is to connect the dots from initial infiltration, through lateral movement, to any exfiltration. This process allows for a quicker understanding of the impact and the response actions needed.
The more data sources and security vectors you bring into a single, integrated XDR platform, the greater the correlation opportunities, and the more comprehensive the investigation and response.
For example, today an analyst might use an endpoint detection and response (EDR) tool to get detailed visibility into suspicious activity on managed endpoints – but then have a separate siloed view of network security alerts and traffic analysis. As for the cloud workloads, the analyst likely has limited visibility to identify suspicious activity.
All parts of the environment generate noisy alerts that are likely sent to a security information and event management (SIEM). The analyst can see the alerts, but misses out on a detailed record of all the activity between alerts. Without additional correlation, the analyst will miss important attack details left buried in alerts without context or a way to connect related events.
XDR brings the layers together so security analysts can see the bigger picture and quickly explain what may be happening in the enterprise, including how the user got infected, what the first point of entry was, and what or who else is part of the same attack.
