What indicator helps incident responders identify wireless network incidents?

1. Outbound traffic to public IP addresses

2. Unusual login attempts

3. Excessive local network communication

4. Inconsistent device pairing

The correct answer is: Outbound traffic to public IP addresses

The indicator that helps incident responders identify wireless network incidents is inconsistent device pairing. This indicator directly relates to irregularities that can occur in the connection of devices to the wireless network. In the context of wireless networks, consistent pairing usually indicates that devices are securely and correctly authenticated to the network. If there are discrepancies or inconsistencies in how devices are connecting—such as unexpected devices pairing or frequent disconnections and reconnections—it could signify a security threat or intrusion attempt. Monitoring for inconsistent device pairing helps responders detect potential unauthorized access or other malicious activities, as it raises a red flag about the integrity of the wireless network. It encourages a deeper investigation into who is attempting to connect to the network and whether those attempts are legitimate or potentially harmful. In contrast, outbound traffic to public IP addresses, unusual login attempts, and excessive local network communication may not provide specific insights into wireless anomalies. While these are indeed important indicators of potential security incidents, they are not as closely tied to the unique characteristics and vulnerabilities of wireless networks.
