Claude reasons about the Purdue/ISA-95 model, analyzes industrial protocols passively, maps adversary behavior to **MITRE ATT&CK for ICS**, and aligns recommendations to **IEC 62443** and the **NIST SP 800-82** guidance.\n\n> **SAFETY & AUTHORIZATION — READ FIRST**: OT systems control physical processes; a crashed PLC can mean equipment damage, environmental release, or loss of life. **Default to passive, non-intrusive methods.** Never send active scans, writes, or protocol fuzzing to production OT without written authorization, asset-owner sign-off, and a tested rollback/safety plan — ideally on a test bench or during a maintenance window. Confirm scope and the \"do-no-harm\" boundary before proceeding.\n\n---\n\n## Activation Triggers\n\nThis skill activates when the user asks about:\n- ICS / SCADA / OT / DCS security or industrial network assessment\n- Modbus, DNP3, S7comm, EtherNet/IP, BACnet, OPC-UA, IEC 61850/104 protocols\n- PLC, RTU, HMI, historian, or engineering-workstation security\n- Purdue model / ISA-95 segmentation and IT/OT boundary review\n- IEC 62443, NIST SP 800-82, or NERC CIP alignment\n- MITRE ATT&CK for ICS technique mapping\n- Internet-exposed ICS devices (Shodan/Censys dorks) or ICS asset inventory\n- OT threat detection, anomaly monitoring, or ICS incident response\n\n---\n\n## Prerequisites\n\n```bash\npip install requests pyyaml\n# Protocol libraries (lab use): pip install pymodbus scapy\n```\n\n**Optional enhanced capabilities:**\n- Wireshark / `tshark` with ICS dissectors (Modbus, DNP3, S7, ENIP, GOOSE)\n- `nmap` ICS NSE scripts (use read-only scripts only, with care)\n- GRASSMARLIN / passive asset-discovery tooling\n- Shodan/Censys access for exposure checks (passive, external)\n\n---\n\n## Core Capabilities\n\n### 1. Architecture & Purdue Model Review\n\nWhen asked to review OT architecture, map assets to Purdue levels and assess the boundaries:\n\n| Level | Zone | Assets | Key control |\n|-------|------|--------|-------------|\n| 4–5 | Enterprise / IT | ERP, business network, internet | Should never directly reach L0–L2 |\n| 3.5 | **IDMZ** | Jump hosts, patch/AV relays, historian replica | Brokered, inspected IT↔OT traffic only |\n| 3 | Operations | SCADA servers, historians, engineering WS | Hardened, monitored |\n| 2 | Supervisory | HMIs, control servers | |\n| 1 | Control | PLCs, RTUs, IEDs | |\n| 0 | Process | Sensors, actuators, drives | |\n\nFlag: missing IDMZ, flat IT/OT networks, dual-homed engineering workstations, remote vendor access bypassing the DMZ, and any direct path from L4/L5 to L0–L2.\n\n### 2. Industrial Protocol Analysis (Passive-First)\n\nPrefer reading a SPAN/TAP capture over active probing. From a PCAP, identify:\n- **Modbus/TCP (502)** — function codes; flag writes (FC 5/6/15/16), unauthenticated reads, exposure beyond the cell.\n- **DNP3 (20000)** — operate/direct-operate, lack of Secure Authentication (SAv5).\n- **S7comm / S7comm-plus (102)** — PLC start/stop, program upload/download.\n- **EtherNet/IP + CIP (44818/2222)** — forward-open, attribute writes.\n- **OPC-UA (4840)** — security policy `None`, anonymous sessions.\n- **IEC 61850 GOOSE/MMS, IEC 60870-5-104 (2404), BACnet (47808)** as present.\n\nNote that **most ICS protocols have no authentication or encryption by design** — any reachable client can issue commands. Use `scripts/ics_protocol_analyzer.py` to summarize an exported PCAP and flag write/control operations and unexpected talkers.\n\n### 3. Exposure & Asset Discovery\n\n- **Passive inventory** from captures (MAC/OUI → vendor, protocol → device role).\n- **External exposure** (read-only, external) via Shodan/Censys dorks — never expose live device details publicly:\n  - `port:502 product:Modbus`, `port:20000 source address`, `tag:ics`, `\"Siemens, SIMATIC\"`, `port:47808`, `\"Schneider Electric\"`.\n- For any device that *must* be reachable, document why, the compensating controls, and whether it should be behind the IDMZ instead.\n- Active scanning, if authorized: use only read-only `nmap` NSE (`modbus-discover`, `s7-info`, `bacnet-info`, `enip-info`) with low rate, never against safety-instrumented systems (SIS).\n\n### 4. Threat Modeling — MITRE ATT&CK for ICS\n\nMap plausible adversary paths using the ICS matrix tactics: Initial Access → Execution → Persistence → Evasion → Discovery → Lateral Movement → Collection → Command-and-Control → **Inhibit Response Function** → **Impair Process Control** → **Impact**. Reference high-signal techniques (e.g., T0883 Internet-Accessible Device, T0836 Modify Parameter, T0831 Manipulation of Control, T0814 Denial of Service, T0816 Device Restart/Shutdown). Anchor scenarios to real tradecraft (Stuxnet, TRITON/TRISIS targeting SIS, Industroyer/CRASHOVERRIDE, PIPEDREAM/INCONTROLLER).\n\n### 5. IEC 62443 / NIST SP 800-82 Alignment\n\n- Define **zones and conduits**; assign **Security Levels (SL 1–4)** per zone based on threat.\n- Review against IEC 62443-3-3 system requirements (FR1 IAC, FR2 UC, FR3 system integrity, FR4 data confidentiality, FR5 restricted data flow, FR6 timely response, FR7 resource availability).\n- Map to NIST SP 800-82r3 control overlays and NERC CIP where the asset owner is in scope (BES).\n\n### 6. OT-Aware Detection & Incident Response\n\n- Detection: baseline normal protocol talkers and command rates; alert on unexpected write/program-download, new engineering connections, off-hours commands, and L4→L1 traffic.\n- IR (coordinate with → Skill 07, but OT-modified): **safety and process continuity outrank evidence preservation**; involve process/safety engineers; prefer passive collection; have a manual-operations fallback before isolating anything.\n\n---\n\n## Output Standards\n\n```markdown\n# OT/ICS Security Assessment — [Site / System]\nDate: [Date] | Scope: [Zones/Assets] | Method: [Passive/Active] | Analyst: [Name]\nSafety constraints honored: [yes — passive only / window used / etc.]\n\n## Executive Summary\n[Posture, top safety-relevant risks]\n\n## Purdue / Zone-Conduit Map\n[Levels, boundaries, IDMZ status]\n\n## Findings\n### [O-01] Modbus writes reachable from IT VLAN  (Critical)\n- ATT&CK ICS: T0883, T0836 | IEC 62443 FR5\n- Evidence: [pcap flow IT-host → PLC FC16]\n- Process impact: [what physical effect is possible]\n- Remediation: [conduit/firewall rule, IDMZ broker, read-only segmentation]\n\n## IEC 62443 Zone/SL Recommendations\n| Zone | Current SL | Target SL | Gap |\n\n## Prioritized Remediation (safety-weighted)\n```\n\n---\n\n## Script Reference\n\n### `ics_protocol_analyzer.py`\n```bash\n# Summarize an exported PCAP CSV/JSON (from tshark) and flag control/write ops\ntshark -r capture.pcap -T json > capture.json\npython scripts/ics_protocol_analyzer.py --input capture.json --output ics_report.json\n\n# Generate Shodan/Censys exposure dorks for a vendor/protocol set\npython scripts/ics_protocol_analyzer.py --dorks --vendor siemens --output dorks.txt\n```\n\n---\n\n## Skill Integration\n\n| Next Step | Condition | Target Skill |\n|-----------|-----------|--------------|\n| Deep PCAP / IDS rules | Network capture available | → Skill 08 |\n| Firmware / device RE | PLC/RTU firmware obtained | → Skill 04 |\n| OT incident handling | Active incident | → Skill 07 |\n| Detection content | SIEM/OT-monitoring rules needed | → Skill 12 |\n| IT-side segmentation hardening | IT/OT boundary hosts | → Skill 15 |\n\n---\n\n## References\n\n- [MITRE ATT&CK for ICS](https://attack.mitre.org/matrices/ics/)\n- [NIST SP 800-82 Rev. 3 — Guide to OT Security](https://csrc.nist.gov/pubs/sp/800/82/r3/final)\n- [IEC 62443 series — Industrial Automation and Control Systems Security](https://www.isa.org/standards-and-publications/isa-standards/isa-iec-62443-series-of-standards)\n- [CISA — ICS Recommended Practices & Advisories](https://www.cisa.gov/topics/industrial-control-systems)\n- [NERC CIP Standards](https://www.nerc.com/pa/Stand/Pages/CIPStandards.aspx)\n","tagline":"Operational Technology and industrial control system security — Purdue model segmentation, industrial protocol analysis (Modbus, DNP3, S7, EtherNet/IP), PLC/HMI exposure, IEC 62443 alignment, and MITRE ATT&CK for ICS, for authorized and safety-conscious assessments","category":"security","tags":["cybersecurity","ot-security","ics","scada","modbus","dnp3","plc","iec62443","attack-ics","purdue-model"],"author":"Masriyan","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github candidate review","sourceDetail":"Masriyan/Claude-Code-CyberSecurity-Skill","creatorName":"Masriyan","creatorUrl":"https://github.com/Masriyan","sourceUrl":"https://github.com/Masriyan/Claude-Code-CyberSecurity-Skill/tree/main/skills/18-ot-ics-security","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/masriyan-ot-ics-scada-security#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
