# Performing Power Grid Cybersecurity Assessment

## Overview

Cybersecurity skill for performing power grid cybersecurity assessment. Follows industry best practices and security standards.

## When to Use
**Trigger phrases:**
- "performing power grid cybersecurity assessment"
- "This skill covers conducting cybersecurity assessments of electric power grid in"


- When conducting periodic cybersecurity assessments of power grid facilities per NERC CIP requirements
- When assessing substation automation systems using IEC 61850 GOOSE and MMS protocols
- When evaluating the security of an Energy Management System (EMS) or SCADA control center
- When assessing synchrophasor (PMU) networks and wide-area monitoring systems
- When preparing for regional entity compliance audits or internal security reviews

**Do not use** for non-BES systems below NERC registration thresholds, for general OT assessment without power grid specifics (see performing-ot-network-security-assessment), or for physical security assessment of generation facilities without cyber scope.


## When NOT to Use

- When you lack proper authorization for testing
- For production systems without change management
- When the task requires legal or compliance expertise beyond technical scope


## Prerequisites

- Understanding of electric power grid architecture (generation, transmission, distribution)
- Familiarity with NERC CIP standards and BES Cyber System categorization
- Knowledge of power grid protocols (IEC 61850, IEC 60870-5-104, DNP3, ICCP/TASE.2)
- Passive monitoring tools for substation network traffic analysis
- Access to EMS/SCADA architecture documentation and network diagrams

## Workflow

```python
# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs(text: str) -> dict:
    return {k: re.findall(v, text) for k, v in IOC_PATTERNS.items()}
```

1. **Plan Operations** — Define objectives, scope, and success criteria for power grid cybersecurity assessment operations.
2. **Prepare Environment** — Set up tools, access, and data sources required for power grid cybersecurity assessment.
3. **Execute Core Workflow** — Perform the power grid cybersecurity assessment operations following established procedures.
4. **Validate Results** — Verify that results meet quality standards and objectives.
5. **Report Findings** — Document results, observations, and recommendations.
6. **Follow Up** — Track remediation actions and verify fixes where applicable.

## Tools

- **Analysis Platform** — Data processing and visualization
- **Collaboration Tools** — Team coordination and knowledge sharing


## Process

1. **Reconnaissance** — Gather target information, identify attack surface, enumerate services
1. **Analysis/Exploitation** — Execute the technique, analyze results, document findings
1. **Reporting** — Document IOCs, write findings, provide remediation recommendations

## Verification

- [ ] All power grid cybersecurity assessment procedures executed completely and documented
- [ ] Findings validated against multiple data sources
- [ ] False positives identified and filtered
- [ ] Results documented with evidence and timestamps
- [ ] Recommendations provided with risk-based prioritization

## Anti-Rationalization Table

| Rationalization | Reality |
|---|---|
| "We are too small to be targeted" | Automated attacks target everyone. Size does not matter. |
| "Security slows us down" | A breach slows you down 100x more. Build security in from the start. |
| "We will fix it after launch" | Vulnerabilities in production are exploited within hours. Fix before deploy. |
