A method and system for securing data transmission in communication networks is disclosed. The method includes the steps of allocating a sequence ID (SQID) to each of a plurality of packets. The SQID is embedded in an Internet Protocol (IP) header of an associated packet from the plurality of packets. The method further includes grouping the plurality of packets into at least one cluster based on at least one of a distance amongst at least one IP attribute associated with destination address of each of the plurality of packets and variance in IP attributes associated with destination address of each of the plurality of packets. The method includes transmitting each of the at least one cluster to an associated destination address. Each cluster in the at least one cluster includes a set of packets from the plurality of packets and at least a domain-name is same in destination address.
