MAC spoofing
Hackers use MAC spoofing to impersonate a legitimate network user.

NIC to issue the floods of de-association frames, forcing clients to drop their association with the access point. Thus the hacker now controls access to the network.

Malicious association
The hacker configures his device to behave as a functioning access point.
When a user’s laptop or station broadcasts a probe for an AP, it encounters the hacker’s device, which responds with an association. At this point, the legitimate user’s computer can be mined for any and all information, including MAC address, SSID, pass codes, etc.

Man-in-the-middle attacks
The hacker sends a de-authorization to a network device, which drops its association to its access point and begins searching for a new access point. It finds the hacker’s station and associates with it, and allowing him to change or steal data at will.

• Adjust the default SSID.
• Use strong encryption.
• Set up mutual authentication between the client and the network.
• Use VPNs or WEP combined with MAC address control lists to secure business specific devices.
• Use uniqueness networking in combination with VLANs to restrict access to network resources.
