What is a consideration for implementing wireless containment in response to unauthorized devices discovered by ArubaOS Wireless Intrusion Detection (WIP)?

Wireless containment involves actively transmitting de-authentication or disassociation frames to disrupt the connection between an unauthorized access point and its clients. This action can be legally problematic as it can be construed as a denial-of-service (DoS) attack, especially if it inadvertently affects legitimate neighboring wireless networks that are not owned by your organization. Therefore, before implementing any form of wireless containment, whether manual or automatic, a company must consult its legal department to understand the potential liabilities and ensure compliance with local and national regulations regarding wireless transmissions.

A. Automatic containment is generally discouraged as a best practice due to the high risk of disrupting legitimate neighboring networks, which can lead to legal issues and operational conflicts.
B. Wireless containment targets the air interface by sending 802.11 management frames. It can disrupt any target AP and its clients within radio range, not just those on the corporate LAN.
D. Wireless containment has a higher risk of affecting legitimate neighbors than wired containment (e.g., shutting down a switch port), which is precise and has no collateral impact on other networks.
