###################################

Atomic OSSEC is a Host-based Intrusion Detection System (HIDS) used for security detection, visibility, and compliance monitoring. It is based on a multi-platform agent that forwards system data (for example log messages, file hashes, and detected anomalies) to a central manager, where it is further analyzed and processed, resulting in security alerts. Agents convey event data to the central manager for analysis via a secure and authenticated channel.

Additionally, AEO provides a centralized syslog server and an :doc:`agentless configuration monitoring </AEO/agentless/index>` system that offers security insight into events and changes on agentless devices such as firewalls, switches, routers, access points, network appliances, and similar gear.

:doc:`Atomic Inspector </AEO/inspector/index>` is an OpenSearch-based **analyst console** installed on the **hub**; **alerts from the hub** are passed into Inspector for search and investigation workflows.
