In an HPE Aruba Networking AOS-8 solution, the Wireless Intrusion Prevention (WIP) system is used to detect and classify rogue Access Points (APs). When a rogue AP is detected, the AOS system provides various pieces of information about the detected radio, such as the SSID, BSSID, match method, match type, confidence level, and the devices that detected the rogue AP. The goal is to locate the physical rogue device, which requires identifying its approximate location in the network environment.
Option A, "The detecting devices," is correct. The "detecting devices" refer to the authorized APs or radios that detected the rogue AP’s signal. This information is critical for locating the rogue device because it provides the physical locations of the detecting APs. By knowing which APs detected the rogue AP and their signal strength (RSSI) readings, you can triangulate the approximate location of the rogue AP. For example, if AP-1 in Building A and AP-2 in Building B both detect the rogue AP, and AP-1 reports a stronger signal, the rogue AP is likely closer to AP-1 in Building A.
Option B, "The match method," is incorrect. The match method (e.g., "Plus one," "Eth-Wired-Mac-Table") indicates how the rogue AP was classified (e.g., based on a BSSID close to a known MAC or its presence on the wired network). While this helps understand why the AP was classified as rogue, it does not directly help locate the physical device.
Option C, "The confidence level," is incorrect. The confidence level indicates the likelihood that the AP is correctly classified as rogue (e.g., 90% confidence). This is useful for assessing the reliability of the classification but does not provide location information.
Option D, "The match type," is incorrect. The match type (e.g., "Rogue," "Suspected Rogue") specifies the category of the classification. Like the match method, it helps understand the classification but does not aid in physically locating the device.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"When a rogue AP is detected by the Wireless Intrusion Prevention (WIP) system, the ‘detecting devices’ information lists the authorized APs or radios that detected the rogue AP’s signal. This is the most useful information for locating the rogue device, as it provides the physical locations of the detecting APs. By analyzing the signal strength (RSSI) reported by each detecting device, you can triangulate the approximate location of the rogue AP. For example, if AP-1 and AP-2 detect the rogue AP, and AP-1 reports a higher RSSI, the rogue AP is likely closer to AP-1." (Page 416, Rogue AP Detection Section)
Additionally, the HPE Aruba Networking Security Guide notes:
"To locate a rogue AP, use the ‘detecting devices’ information in the AOS Detected Radios page. This lists the APs that detected the rogue AP, along with signal strength data, enabling triangulation to pinpoint the rogue device’s location." (Page 80, Locating Rogue APs Section)
