Apparatus and method for security control in IoT infrastructure environment

摘要

Security control technology that includes a network access blocking function that prevents security threats from devices from spreading to the IoT infrastructure in the Internet of Things (IoT) infrastructure environment, and a network access blocking release function that minimizes service delays due to network access blocking Suggest. The present invention prevents the spread of security threats when a security threat such as DDoS attack and malicious code spread is detected in an IoT infrastructure consisting of a service server, an IoT gateway, and an IoT end device (mixed with'device'). To prevent security threats early, block network access to end devices where security threats occur and/or groups of end devices having the same or similar properties, but block access to minimize service delays caused by blocked devices. Provides an apparatus and method for canceling network access blocking by checking the security status of devices belonging to the group in a certain order.
