securing-historian-server-in-ot-environment

This skill covers hardening and securing process historian servers (OSIsoft PI, Honeywell PHD, GE Proficy, AVEVA Historian) in OT environments. It addresses network placement across Purdue levels, access control for historian interfaces, data replication through DMZ using data diodes or PI-to-PI connectors, SQL injection prevention in historian queries, and integrity protection of process data used for safety analysis, regulatory reporting, and process optimization.

What does this entry provide?

securing-historian-server-in-ot-environment is an agent skill entry in ChatHome Skills, sourced from GitHub Skill Search and scored 58/100. # Securing Historian Server in OT Environment ## When to Use - When deploying a new historian server in an OT environment and configuring it securely from the s. As an agent skill, it packages a reusable instruction set that AI coding agents such as Codex and Claude Code can load to perform this task without hand-written glue code. ChatHome Skills discovered this entry through its daily ingest of official registries and GitHub discovery queries, and re-verifies repository facts, freshness signals, and install metadata on every run. The quality score weighs official-registry presence, a working install command, license clarity, GitHub star trajectory, and repository freshness — the full formula is on the Sources page.

How is this score calculated?

Weighted across six dimensions, scored 0-100.
Provenance (25): listed in an official or curated registry.
Installability (25): a runnable install command beats a declared transport, which beats a source checkout.
Maintenance (20): recency of the last push; archived entries score zero here.
Adoption (20): repository stars on a log curve.

Security signals

Scan coverage: Install metadata and the indexed document body.

Automated signals from install metadata and a bounded skill body — not a full code security audit and not a recursive source or dependency review.
