# Cybersecurity Risk Assessor Skill

## Purpose

The Cybersecurity Risk Assessor Skill evaluates cybersecurity risks for medical devices per FDA guidance and IEC 81001-5-1, supporting threat modeling, vulnerability assessment, and security control implementation.

## Capabilities

- Threat modeling (STRIDE methodology)
- Vulnerability assessment
- SBOM (Software Bill of Materials) generation
- Security control identification
- Penetration testing planning
- Cybersecurity documentation for FDA submissions
- Attack surface analysis
- Security architecture review
- Coordinated vulnerability disclosure planning
- Postmarket cybersecurity management
- Patch management planning

## Usage Guidelines

### When to Use
- Assessing device cybersecurity risks
- Planning penetration testing
- Preparing FDA cybersecurity submissions
- Managing software dependencies

### Prerequisites
- Software architecture documented
- Network connectivity defined
- Data flows identified
- Third-party components cataloged

### Best Practices
- Integrate cybersecurity from design inception
- Maintain current SBOM
- Plan for security updates throughout lifecycle
- Establish vulnerability disclosure process

## Process Integration

This skill integrates with the following processes:
- Software Development Lifecycle (IEC 62304)
- Medical Device Risk Management (ISO 14971)
- 510(k) Premarket Submission Preparation
- Post-Market Surveillance System Implementation

## Dependencies

- FDA Cybersecurity guidance
- IEC 81001-5-1 standard
- SBOM tools (CycloneDX, SPDX)
- Vulnerability databases (NVD, CVE)
- Threat modeling frameworks
