ELASTICSEARCH
Elasticsearch is a search and analytics engine often used for log and event data analysis, full-text search, and real-time data visualization.
Elasticsearch can ingest and index large log and event datasets from various sources, including network devices, servers, applications, and security tools. You can use Elasticsearch to search, filter, and analyze this data for indicators of compromise (IOCs), security incidents, and anomalous behavior.
