A company is using HPE Aruba Networking ClearPass Device Insight (CPDI) (the standalone application). In the CPDI security settings, Security Analysis is On, the Data Source is ClearPass Device Insight, and Enable Posture Assessment is On. You see that a device has a Risk Score of 90.
What can you know from this information?
1. Understanding CPDI Risk Score and Posture Analysis
The Risk Score in ClearPass Device Insight (CPDI) is a numerical value representing the overall risk level associated with a device. It considers factors such as:
Posture Assessment: The device's compliance with health policies (e.g., OS updates, antivirus status).
Security Analysis: Vulnerabilities detected on the device, such as known exploits or weak configurations.
A Risk Score of 90 indicates a high-risk device, suggesting that the posture is unhealthy and vulnerabilities have been detected.
2. Analysis of Each Option
A . The posture is unknown, and CPDI has detected exactly four vulnerabilities on the device:
Incorrect:
The posture cannot be 'unknown' because posture assessment is enabled in the settings.
CPDI does not explicitly indicate the exact number of vulnerabilities directly through the Risk Score.
B . The posture is healthy, but CPDI has detected multiple vulnerabilities on the device:
Incorrect:
A Risk Score of 90 is too high for a 'healthy' posture. A healthy posture would typically result in a lower Risk Score.
C . The posture is unhealthy, and CPDI has also detected at least one vulnerability on the device:
Correct:
A high Risk Score of 90 indicates an unhealthy posture.
The presence of vulnerabilities (based on Security Analysis being enabled) further justifies the high Risk Score.
This combination of unhealthy posture and detected vulnerabilities aligns with the Risk Score and configuration provided.
D . The posture is unhealthy, but CPDI has not detected any vulnerabilities on the device:
Incorrect:
If no vulnerabilities were detected, the Risk Score would not be as high as 90, even if the posture were unhealthy.
Final Interpretation
From the configuration and Risk Score provided, the device's posture is unhealthy, and at least one vulnerability has been detected by CPDI.
