A honeypot can be used to launch a Man-in-the-Middle (MITM) attack on wireless clients by examining wireless clients' probe requests and then broadcasting the SSIDs in those probes. Clients with those SSIDs in their preferred network list may then automatically connect to the honeypot, believing it to be a legitimate network. Once the client is connected to the attacker's honeypot, the attacker can intercept, monitor, or manipulate the client's traffic, effectively executing a MITM attack.

For following Aruba best security practices, the setting you should change is to disable local authentication. When integrating with an external RADIUS server like ClearPass Policy Manager (CPPM) for authenticating administrative access to the Mobility Controller (MC), it is a best practice to rely on the external server rather than the local user database. This practice not only centralizes the management of user roles and access but also enhances security by leveraging CPPM's advanced authentication mechanisms.

In an Aruba network, when setting up a WPA3-Enterprise network that also supports WPA2-Enterprise clients, you would typically configure the network to operate in a transitional mode that supports both protocols. CNSA (Commercial National Security Algorithm) mode is intended for networks that require higher security standards as specified by the US National Security Agency (NSA). However, for compatibility with WPA2 clients, which do not support CNSA requirements, you would disable CNSA mode. WPA3 can use 256-bit encryption keys, which offer a higher level of security than the 128-bit keys used in WPA2.

In the context of an Aruba Mobility Controller (MC) configuration, a client will receive the default role assignment if they have passed 802.1X authentication and the authentication server did not send an Aruba-User-Role Vendor Specific Attribute (VSA). The default role is assigned by the MC when a client successfully authenticates but the authentication server provides no specific role instruction. This behavior ensures that a client is not left without any role assignment, which could potentially lead to a lack of network access or access control. This default role assignment mechanism is part of Aruba's role-based access control, as documented in the ArubaOS user guide and best practices.
