Abstract

A method and a system of restricting data packet transmission of an apparatus at a network node. The network node, during a first time period, updates a whitelist and does not restrict data packet transmission according to the whitelist. After the first time period, the network node determines corresponding destination address of each of the data packets and allows the data packets to be sent to the corresponding destination address if a criteria is satisfactory. The network node does not allow the data packets to be sent to the corresponding destination address if the criteria is not satisfactory. The whitelist is comprised of at least one destination address. The criteria is based on the at least one destination address. The whitelist list is stored in non-transitory computer readable storage medium in the network node.
