Abstract
A method for processing a denial of service (DOS) includes: receiving a de-authentication/disassociation (D/D) frame by an access point (AP), determining by the AP a state of security association establishment between the AP and a client device, maintaining a connection between the AP and the client device if the security association is incomplete, sending a probe packet from the AP to the client device if security association is complete and the connection between the AP and the client device is in a non-PMF (protected management frames) setting, maintaining the connection if the client device responds to the probe packet, and terminating the connection if the client device does not respond to the probe packet.
