Log aggregation / SIEM
A Security Information and Event Management system centralizes logs from many sources (syslog, authd, web access logs, firewall) and enables correlation and alerting. Examples: Splunk, Elasticsearch/Kibana, Gravwell.
How this shows up at NCAE
NJIT's 2025 nationals 3rd-place team used **Gravwell** to trace how red team moved through their systems. At your scale, `journalctl -f | tee /root/competition.log` is a minimum viable SIEM.
