Claim Text:
1. A computer-implemented method for thwarting illegitimate initialization attempts, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising: receiving an initialization packet designed to initiate communication between a source port on a source computing device and a destination port on a destination computing device; creating a record that comprises the source port on the source computing device and the destination port on the destination computing device; thwarting potential illegitimate initialization attempts by intentionally dropping the initialization packet; receiving an additional initialization packet; determining that the additional initialization packet is from the same source port on the same source computing device and is directed to the same destination port on the same destination computing device as the original initialization packet by comparing the additional initialization packet with the record; sending an acknowledgement packet that initiates communication between the source computing device and the destination computing device in response to determining that the additional initialization packet is from the same source port on the same source computing device and is directed to the same destination port on the same destination computing device as the original initialization packet.
