detecting-attacks-on-historian-servers

Detect cyber attacks on OT historian servers (OSIsoft PI, Ignition, GE Proficy, Wonderware InSQL) using a Python detector that flags unauthorized queries, data manipulation, and lateral-movement indicators as historians pivot between IT and OT networks. Use when monitoring historians bridging IT/OT zones for compromise, investigating historian-specific CVE exploitation, or validating historian data integrity after a suspected OT incident.

# Detecting Attacks on Historian Servers

## When to Use

- When monitoring historian servers that bridge IT and OT networks for compromise indicators
- When detecting unauthorized queries or data manipulation in process historian databases
- When investigating lateral movement through historian servers between IT and OT zones
- When responding to alerts about exploitation of historian-specific vulnerabilities (CVE-2025-0921)
- When validating historian data integrity after a suspected OT security incident

**Do not use** for general database security monitoring (see database security skills), for historian deployment and configuration, or for IT-only data warehouse security.
