Embodiment Construction
[0029] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0030] The existing defense method of the Industrial Internet of Things is to improve the security of the network and its applications through multi-level defense systems such as firewalls, security gateways, access control, intrusion detection, virus killing, and data encryption. However, the network security incidents and the serious consequences th...

The present application discloses a defense method and device for the Industrial Internet of Things, which are used to solve the problem that the industrial Internet of Things defense method cannot effectively prevent network attacks. The method includes: monitoring the TCP connection process in the Industrial Internet of Things, and obtaining abnormal data packets; comparing with a preset risk database, and determining that there are new security risks when the comparison results are different; The address of the node that has no connectivity relationship with the attacked node is taken as the first set; the address of the node that has a connectivity relationship with the first attacked node is taken as the second set; if it is determined that the attacker adopts the blind scanning strategy, the address of the node in the first set The first target address is selected, and when it is determined that the attacker adopts the non-blind scanning strategy, the first target address is selected from the second set to replace the address of the first attacked node. The present application can effectively improve the defense capability of the Industrial Internet of Things through the above method.
Description
technical field [0001] The present application relates to the technical field of network security, in particular to a defense method and device for the Industrial Internet of Things. Background technique [0002] With the continuous development of Internet of Things technology, it has been popularized in various fields. In particular, the wide application of the Industrial Internet of Things in the industrial field has greatly improved industrial production efficiency and product quality. However, with more and more open network connections and more and more data information interacting, industrial control systems, networked devices, and industrial cloud platforms are vulnerable to malicious network attacks. As a result, data leakage, production interruption, capital loss and other consequences of industrial manufacturing enterprises have been caused. [0003] Existing IoT defenses usually use firewall technology and intrusion detection technology to monitor the network in...
