Architecture: an rsyslog relay server receives logs from all devices on ports 514 (TCP) and 8514 (UDP) and forwards them to a 2-node Elasticsearch cluster (both nodes configured as master, for redundancy) via Logstash, with a custom Logstash filter/pipeline tagging entries by hostname and program name. Covers building alert rules from specific Windows Event IDs (account disabled/enabled/deleted, privilege/security-group escalation, failed logins, password resets, audit log clears) and equivalent Linux alerts (sudo escalation, failed su attempts, anti-brute-force config changes), plus McAfee (ePO) event alerts and ELK's own internal health alerts (cluster health, disk/CPU usage, shard/thread-pool sizing). Also walks through building Kibana dashboards for authentication-failure trends, and the snapshot/backup mechanism -- an LVM volume shared across both nodes via NFS, snapshotted via Elasticsearch's Curator</ins>/<ins style="font-weight: bold; text-decoration: none;">snapshot API, which the presenter had already used once to recover from an accidental data deletion during setup.</ins></div></td></tr> </table>
