HPE7-A02 Exam Dumps - HP Certification Questions and Answers

To show the security team information about MAC spoofing attempts detected by HPE Aruba Networking ClearPass Policy Manager (CPPM), you should use ClearPass Insight to run an Active Endpoint Security report. ClearPass Insight provides comprehensive reporting capabilities that include detailed information on security incidents, such as MAC spoofing attempts. By generating this report, you can provide the security team with a clear overview of the detected spoofing activities, including the endpoints involved and the context of the events.

Gateway Threat Count Alert

This alert indicates that the gateway has detected threats in traffic passing through it. HPE Aruba Networking Central provides tools to investigate and analyze these threats in detail.

Analysis of Each Option

A. Use HPE Aruba Networking Central tools to run a Network Check on the gateway with which the alert is associated:

Incorrect:

Network Check tools in Central are primarily used for connectivity and performance diagnostics, not for analyzing detected threats.

This does not provide insight into the specific threats triggering the Gateway Threat Count alert.

B. Use Live Monitoring on the gateway to download a packet capture of recent traffic flowing through the gateway:

Incorrect:

Live Monitoring and packet capture can provide raw traffic data, but interpreting this requires significant manual analysis.

The Gateway Threat Count alert already provides summarized threat insights that are easier to access via the threat list.

C. Check the threat list for the gateway associated with the alert. Access threat details and download packet info:

Correct:

The threat list is specifically designed to display detailed information about detected threats, such as their type, severity, and source/destination.

Administrators can access this list in Central for the affected gateway, view granular details, and even download associated packet data for deeper inspection.

D. Check the gateway's Audit Trail in HPE Aruba Networking Central for more details about the threats that triggered the alert:

Incorrect:

The Audit Trail tracks configuration changes and administrative actions, not the details of detected threats.

It is not relevant for investigating the Gateway Threat Count alert.

Final Recommendation

To gather more information about what caused the Gateway Threat Count alert to trigger, check the threat list for the associated gateway. This provides detailed threat information and the option to download packet data for further analysis.

Understanding Gateway IDS/IPS Alerts in Aruba Central Documentation.

Best Practices for Threat Investigation Using Aruba Central.

When Wireless IDS/IPS infrastructure detection reports RTS (Request to Send) and CTS (Clear to Send) rate anomalies triggered by neighboring APs, it is often an indication of unusual, but not necessarily malicious, behavior. These anomalies can be caused by neighboring APs operating normally but under specific conditions that trigger the alerts. Before assuming a security threat, it is recommended to tune the event thresholds to better match the environment and reduce false positives. This approach helps to distinguish between normal operations and potential DoS attacks.

1. Understanding the Role Mapping Evaluation:

Role mapping is set to "Evaluate: Select first," meaning the first rule that matches the client attributes will determine the role(s) assigned.

Contractors group: Since the client is in the Contractors group (not Managers), Rule 1 in the Role Mapping Policy does not match.

TEAP-Method-1-Status EQUALS Success: This condition matches Rule 2, so the client is assigned the domain-comp role.

No other rules match, so the default role [Other] is not applied.

2. Resulting Role from Role Mapping Policy:

The client is assigned the domain-comp role.

3. Enforcement Policy Evaluation:

Enforcement policy is also set to "Evaluate: Select first," so the first matching rule determines the enforcement profile.

Rule 1 (Tips Role = manager AND domain-comp):

The client only has the domain-comp role, not manager, so this rule does not match.

Rule 2 (Tips Role = manager):

The client does not have the manager role, so this rule does not match.

Rule 3 (Tips Role = domain-comp):

This rule matches the client's role, but it is not evaluated because the enforcement policy already skipped to the default action after failing the first two rules.

4. Default Enforcement Profile:

Since no rule explicitly matches and the policy evaluation stops at the default, the default profile [Deny Access Profile] is applied.

Final Outcome:

The client is denied access because none of the matching rules satisfy the conditions.
