Protected Management Frames (PMF), also known as Management Frame Protection (MFP), is designed to protect clients from denial-of-service (DoS) attacks that involve forged de-authentication and disassociation frames. These attacks can disconnect legitimate clients from the network. PMF provides a way to authenticate these management frames, ensuring that they are not forged, thus enhancing the security of the wireless network.
