The packets show TCP traffic with the FIN, PSH, and URG flags set together. This combination is commonly associated with an Xmas scan, a TCP port scanning technique used to probe target systems and identify open, closed, or filtered ports. A normal TCP session establishment uses a SYN packet first, not FIN/PSH/URG. Because the source host 10.1.14.10 is sending this unusual TCP flag combination to multiple destinations and ports, the behavior strongly indicates reconnaissance or scanning activity rather than legitimate application traffic. It is not best classified as a DoS attack because the exhibit shows probing traffic, not traffic volume or exhaustion behavior. The strongest interpretation is that 10.1.14.10 is almost certainly running a TCP port scan.

For a faster way to discover if a gateway starts detecting threats in traffic, admins should set up email notifications using HPE Aruba Networking Central's global alert settings. This setup ensures that the security team is promptly informed via email whenever the IDS/IPS on the gateways detects any threats, allowing for immediate investigation and response.
1.Email Notifications: By configuring email notifications, admins can receive real-time alerts directly to their inbox, reducing the time to discover and react to security incidents.
2.Global Alert Settings: HPE Aruba Networking Central's global alert settings allow for customization of alerts based on specific security events and thresholds, providing flexibility in monitoring and response.
3.Proactive Monitoring: This proactive approach ensures that the security team is always aware of potential threats without the need to constantly check the Security Dashboard manually.

To fix the issue where authorization fails because the usernames do not exist in the authentication source, you can configure rules in HPE Aruba Networking ClearPass Policy Manager (CPPM) to strip the domain name from the username. When certificates are issued by a Windows CA, the username in the certificate often includes the domain (e.g., [email protected]). ClearPass might not be able to find this format in the authentication source. By stripping the domain name, you ensure that ClearPass searches for just the username (e.g., user) in the authentication source, allowing successful authentication.

* Packet Capture in Aruba Central:
* Aruba Central provides tools for remote packet captures directly from the APs.
* On the "Security" page for the AP, you can initiate a packet capture session, specifying the client device and capture duration.
* The traffic is captured into a PCAP file, which can be downloaded and analyzed using tools like Wireshark.
* Option Analysis:
* Option A: Incorrect. While possible via CLI, Aruba Central provides a simpler method for packet captures.
* Option B: Correct. Aruba Central's "Security" page allows you to capture and export client traffic efficiently.
* Option C: Incorrect. The "Live Events" page focuses on monitoring events, not packet captures.
* Option D: Incorrect. Port mirroring on the switch captures AP traffic but requires more manual configuration and does not isolate client-specific wireless traffic easily.

In a user-based tunneling (UBT) setup with reserved VLAN mode, VLAN 64 is used for routing traffic at the gateways. Since the IoT traffic is tunneled to the AOS-10 gateway:
On the gateways:
VLAN 64 must be configured in the iot-wired role for routing purposes.
On the switches:
VLAN 64 does not need to be configured on the access switch physical uplinks because the IoT traffic is tunneled directly to the gateway and does not rely on VLAN configurations at the access layer switches.
Reserved VLAN mode:
Ensures that traffic is encapsulated within the UBT tunnel, and VLANs like 64 are only relevant at the gateway for routing and enforcement.
Therefore, the correct configuration is to define VLAN 64 in the iot-wired role on the AOS-10 gateways and not on any physical interfaces.
