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.

Apparatus, system, and method for monitoring network security and performance

An aspect of the present disclosure discloses a method for diagnosing a network performance in an apparatus for diagnosing network performance connected to a switching device provided between a first entity and a second entity. The method may include: obtaining at least one mirrored packet for at least one packet transmitted between the first entity and the second entity based on mirroring from the switching device, calculating performance related indicator representing performance of a network service associated with the first entity and the second entity based on at least a part of information included in the at least one mirrored packet, and storing the calculated performance related indicators.

Method, apparatus and system for diagnosing network performance

An aspect of the present disclosure discloses a method for diagnosing the performance of a 5G-based network by a network performance diagnosis device connected to a switching device connected to the 5G-based network. The method comprises the steps of: obtaining at least one mirrored packet for at least one packet transceived from/to a user terminal connected to at least one base station on the basis of mirroring from the switching device; calculating performance-related indicators representing the performance of a network associated with the user terminal and the at least one base station on the basis of at least part of information included in the at least one mirrored packet; and determining whether the 5G-based network operates normally, on the basis of the performance-related indicators.

Method, device, and system for diagnosing performance of 5G mobile communication-based network

Disclosed is a network security monitoring device, which is included in a network comprising a first entity, a second entity, a switching device provided between the first entity and the second entity, and the network security monitoring device connected to the switching device. The device comprises the port for obtaining at least one mirrored packet for at least one packet transmitted and received between the first entity and the second entity on the basis of mirroring from the switching device, and a processor for determining whether a security problem has occurred for a network associated with the first entity and the second entity on the basis of at least some of information included in the at least one mirrored packet.
