Detects IoT devices on a network using protocols like UPnP, mDNS, and SNMP.
3.2 Vulnerability Analysis
Performs vulnerability assessments using CVE databases and configuration analysis.
3.3 Reporting and Remediation
Generates actionable reports and recommends remediation steps for detected vulnerabilities.
4. Implementation Steps
1. **Environment Setup**: Install Python and required
libraries such as Nmap, Scapy, and Shodan API.
2. **Device Discovery**: Implement device discovery using network scanning
tools.
3. **Vulnerability Assessment**: Cross-check device information against public
vulnerability databases.
4. **Data Storage**: Use a database to store scan results and logs.
5. **Report Generation**: Design a reporting tool to provide detailed
vulnerability insights.
6. **Testing and Deployment**: Test in controlled and real-world environments
before deployment.
5. Security Considerations
1. Use secure protocols to communicate with devices.
2. Ensure that the scanner cannot be exploited for malicious purposes.
3. Regularly update the vulnerability database.
6. Tools and Technologies
- **Programming Languages**: Python, Go
- **Libraries and Tools**: Nmap, Scapy, Shodan API
- **Databases**: SQLite, MongoDB
- **Frameworks**: Flask (for web interface), Pandas (for data processing)
7. Testing and Validation
1. Test with a diverse set of IoT devices to ensure broad
compatibility.
2. Validate results by simulating known vulnerabilities.
3. Ensure false positives are minimized through rigorous testing.
