Which ES feature would a security analyst use while investigating a network anomaly?

The Protocol Intelligence Dashboard is specifically designed to help security analysts identify and investigate anomalies within network traffic. This feature offers valuable insights into the protocols being used, the types of communication happening on the network, and any unusual patterns that may suggest suspicious or malicious activity. By providing a visual representation and detailed analysis of protocol-related data, the dashboard aids analysts in correlating network behaviors with known threats and helping to pinpoint irregularities that warrant further investigation.

In contrast, while correlation editors and key indicator searches can assist in broader data analysis and identifying relationships between events, they are not specifically tailored for real-time network protocol analysis. The threat download dashboard typically focuses on external threat intelligence feeds rather than directly analyzing network anomalies. Thus, the Protocol Intelligence Dashboard is the most relevant tool for the task of investigating network anomalies effectively.
