A company has HPE Aruba Networking gateways that implement gateway IDS/IPS.

1. The Need for Faster Threat Notifications

Admins need immediate alerts when threats are detected by the gateway ' s IDS/IPS functionality. Regularly checking the Security Dashboard is inefficient, so an automated notification system is essential for faster response times.

2. Explanation of Each Option

A. Set up Webhooks that are attached to the HPE Aruba Networking Central Threat Dashboard:

Incorrect:

Webhooks are useful for integrating alerts with third-party tools or custom workflows. However, setting up email notifications through global alert settings is faster and simpler for this purpose.

B. Use Syslog to integrate the gateways with HPE Aruba Networking ClearPass Policy Manager (CPPM) event processing:

Incorrect:

Syslog integration with CPPM is typically used for logging and correlating events, not for real-time notifications about threats.

CPPM is better suited for policy enforcement, not instant threat alerts.

C. Set up email notifications using HPE Aruba Networking Central ' s global alert settings:

Correct:

HPE Aruba Networking Central has global alert settings that allow admins to configure email notifications for specific events, such as threat detection.

This is the simplest and most effective way to ensure admins receive immediate notifications when threats are detected by the gateways.

D. Integrate HPE Aruba Networking ClearPass Device Insight (CPDI) with Central and schedule hourly reports:

Incorrect:

While CPDI integration provides enhanced device profiling, it is not directly tied to gateway IDS/IPS threat detection.

Hourly reports are not real-time notifications and would not meet the requirement for faster threat alerts.

Final Recommendation

Setting up email notifications through HPE Aruba Networking Central ' s global alert settings provides the most direct and efficient solution for immediate threat detection alerts.
