Storing and enriching alerts for information security with Elasticsearch

In the blog post, Darren LaCasse discusses how the Elastic Stack, specifically using Elasticsearch and Watcher, can be used to enhance information security alerts by enriching them with additional data, such as MITRE ATT&CK information, and storing them in a separate index for improved reporting and analysis. The process involves transforming alert payloads using a Watcher payload transform to inject new fields, which are then indexed into Elasticsearch, allowing for detailed reporting and visualization through a Canvas dashboard. This approach not only facilitates more meaningful reporting by breaking down alerts by MITRE ATT&CK Techniques and other parameters but also aids analysts by linking key fields to relevant resources, such as MITRE ATT&CK Technique pages and internal triage playbooks, thus speeding up investigation processes. The enriched alert data and its visualization provide deeper insights into potential security threats, enabling a more effective response and enhancing overall security detection capabilities.
