A disclosed network monitoring method includes: obtaining, by a first apparatus, packets from a node outside a network to a first terminal in the network, and packets from the first terminal to a second terminal in the network; transmitting, by the first apparatus and to a third apparatus, information on first plural packets that satisfy a first condition; obtaining, by a second apparatus, packets from the first terminal to the second terminal, and packets from the second terminal to the node; transmitting, by the second apparatus and to the third apparatus, information on second plural packets that satisfy a second condition; receiving, by the third apparatus, the information on the first and second plural packets; and determining, by the third apparatus, whether an attack from outside the network occurred, based on whether a same packet is included in the first and second plural packets.
