Abstract:
1. A method of detecting an unauthorized wireless access point in a network using a computing device, the method comprising: collecting time expiration value data from a plurality of data packets originating from end-user computers of said network; analyzing said time expiration value data to obtain a threshold time expiration value, wherein said threshold time expiration value is derived from collecting time expiration value data from said plurality of data packets; scanning an incoming data packet for said time expiration value; determining whether the time expiration value is the same as a threshold time expiration value; when it is determined that the time expiration value is not the same as the threshold time expiration value, determining whether the incoming data packet is being routed through an authorized access point in the network including determining that said access point that is not an authorized access point when said access point IP address is not in said authorized access point IP address data set; and reporting to a security component of said network when it is determined that the incoming data packet is not being routed through an authorized access point, wherein the time expiration value is unmodified.
