 Denial of Service (DoS) or Availability Attack Detection
A DoS attack attempts to flood an Array with communications requests
so that it cannot respond to legitimate traffic, or responds so slowly that it
becomes effectively unavailable. The Array can detect a number of types
of DoS attacks, as described in the table below.
 Impersonation Detection
These malicious attacks use various techniques to impersonate a
legitimate AP or station, often in order to eavesdrop on wireless
communications. The Array detects a number of types of impersonation
attacks, as described in the table below.
