  • Gateway apparatus, detecting method of malicious domain and hacked host thereof, and non-transitory computer readable medium
    Patent number: 10574695
    Abstract: A gateway apparatus, a detecting method of malicious domain and hacked host thereof, and a non-transitory computer readable medium are provided. The detecting method includes the following steps: capturing network traffics, and parsing traces and channels from the network traffics. Each channel is related to a link between a domain and an Internet Protocol (IP) address, and each trace is related to an http request requested from the IP address for asking the domain. Then, a trace-channel behavior graph is established. The malicious degree model is trained based on the trace-channel behavior graph and threat intelligence. Accordingly, a malicious degree of an unknown channel can be determined, thereby providing a detecting method with high precision.
