Abstract
A testing device () transmits a test packet that increases processing load to a device protected by a security system, the security system performing authentication of a packet transmitted to a to-be-protected device and a packet limit per source IP address. In addition, the testing device () generates a test session according to a scenario when transmitting the test packet and configures a packet so that the test packet uses a plurality of source IP addresses. In addition, the testing device () responds to a response request up to a predetermined stage of authentication among a plurality of stages of authentication performed by the security system so that the security system authenticates the test packet to be valid. In addition, the testing device () monitors, at a predetermined stage, packet filtering situation and processing load of the security system to which the test packet is transmitted.
