The present invention relates to a network security monitoring device and method based on a security packet of a terminal. The network security monitoring method performed by a network monitoring device according to an aspect of the present invention may comprise the steps of: monitoring a state of a client terminal; obtaining a security inspection packet generated on the basis of a result of the monitoring from a network; obtaining a mirroring packet mirrored by a network switching device from the network; and performing a security monitoring with respect to the network on the basis of at least one of the security inspection packet and the mirroring packet.

Network security monitoring device and method based on security packet of terminal

One aspect of the present invention discloses a method by which a network security monitoring apparatus monitors a 5G network. The method by which a network monitoring apparatus monitors a 5G network, according to one aspect of the present invention, comprises the steps of: mirroring and receiving a packet transmitted from a user terminal to a 5G core network and transmitted to a common network through at least one security module; and calculating an index related to network performance by monitoring the mirrored packet, wherein the at least one security module is located between a user plane function (UPF)-related module of the 5G core network and the common network and performs a security-related operation on data from the user terminal, and the network monitoring apparatus is located between the UPF-related module of the 5G core network and the common network and calculates the index related to the network performance according to mirroring of the packet transmitted through the at least one security module.
