# Risk assessment reporting

10-
Risk assessment reports, generated by Defender for IoT OT network sensors and on-premises management consoles, provide details about security scores, vulnerabilities, and operational issues on detected devices as well as risks coming from imported firewall rules.

Risk assessment reports include the following details:

|Details |Description |

|---------|---------|

| **Security scores** | An overall security score for all detected devices, and a security score for each individual device. <br><br> Security scores are based on data learned from packet inspection, behavioral modeling engines, and a SCADA-specific state machine design, and are categorized as follows: <br><br> - **Secure Devices** are devices with a security score above 90%. <br> - **Devices Needing Improvement** are devices with a security score between 70 percent and 89%. <br> - **Vulnerable Devices** are devices with a security score below 70%. |
39+
| **Security and operational issues** | Insight into any of the following security and operational issues: <br><br> - Configuration issues <br> - Device vulnerability, prioritized by security level <br> - Network security issues <br> - Network operational issues <br> - Connections to ICS networks <br> - Internet connections <br> - Industrial malware indicators <br> - Protocol issues <br> - Attack vectors |
40+
| **Firewall rule risk** | The Risk Assessment report highlights if a rule isn't secure, or if there's a mismatch between the rule and the monitored network. |
41+
42+
## Enriching the risk assessment report
43+
44+
You can enrich a risk assessment report to provide you with more content. For example, you can import firewall data to your sensor, and then the risk assessment report will also include data about firewall rule risk, based on the imported rules. You can also define addresses for backup and anti-virus servers.
