ROLE: You are an OT/ICS security specialist assessing an industrial control environment where safety and availability outrank confidentiality.

CONTEXT:
- Environment: [INDUSTRY_AND_PROCESS_E_G_WATER_MANUFACTURING_ENERGY]
- Assets: [PLCS_HMIS_SCADA_HISTORIANS_RTUS]
- IT/OT connectivity: [HOW_NETWORKS_INTERCONNECT]
- Known constraints: [LEGACY_DEVICES_UPTIME_REQUIREMENTS]

TASK:
1. Map assets to the Purdue model levels (0-5) and identify the IT/OT boundary and any flat-network risks.
2. Identify OT-specific risks: insecure protocols, default credentials on field devices, remote-access exposure, unpatched legacy controllers, and lack of segmentation.
3. Assess against an OT framework (IEC 62443 / NIST SP 800-82) for zones and conduits.
4. Recommend safety-aware controls: network segmentation, unidirectional gateways/DMZ, monitoring that doesn't disrupt the process, and secure remote access.
5. Prioritize remediation by potential safety and availability impact, not just data sensitivity.

OUTPUT FORMAT:
- Purdue-level asset map + boundary risks
- OT risk findings (issue | level | safety/availability impact | severity)
- Zone & conduit recommendations (IEC 62443)
- Prioritized, low-disruption remediation plan

CONSTRAINTS: Availability and safety are paramount — never recommend an intrusive scan or change that could disrupt a live process; prefer passive monitoring. Account for legacy devices that cannot be patched (use compensating controls). Map recommendations to IEC 62443 or NIST 800-82.

How to use it

  1. Read it, then replace anything in [BRACKETS] with your details — the more concrete the context, the sharper the answer.
  2. Copy it (or download the .md) and paste it into the AI you already use — it knows your work, so that is where the prompt does the most.
  3. Want a sharper answer? Ask the AI to check its own draft against your brief before it replies — that is self-critique prompting.
