1. A method for responding to denial of service attacks, the method comprising:
identifying an anomaly by comparing one or more traffic data against one or more baseline traffic data;
reporting, based on the identifying the anomaly, the anomaly as a potential attack;
receiving an indication that the anomaly is an attack;
determining that one or more devices are associated with the attack;
allocating a dedicated frequency channel to traffic associated with the attack;
assigning the one or more devices associated with the attack to the dedicated frequency channel;
assigning all devices not associated with the attack to frequency channels other than the dedicated frequency channel; and
localizing, at least one of the one or more devices associated with the attack based at least in part on timing advance values and/or angle of arrival data from one or more network nodes for the at least one of the one or more devices.
