1. A method of monitoring the security of a 5G non-public (NP) network performed by a network security monitoring server apparatus, the method comprising:
mirroring and receiving a packet transmitted from a user terminal or to the user terminal through the 5G non-public network;
receiving a monitoring result of the state of the user terminal from a security monitoring terminal apparatus connected to the user terminal; and
calculating an indicator related to network performance based on at least one of the mirrored packet and the monitoring result,
wherein the packet is a packet of which IP encryption is decrypted, the monitoring result is received based on an IP designated for the monitoring server apparatus, and the monitoring server apparatus is located between a user plane function (UPF) relay module of the 5G non-public network and a public network and calculates the indicator related to network performance by mirroring a packet sent or received through the UPF relay module.
