Embodiment Construction

[0029] The technical solutions in the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the present disclosure.

[0030] It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures.

[0031] Before explaining the present disclosure in detail, the application scenarios of the present disclosure will be introduced first.

[0032] The network is composed of communication and interconnection between multiple network devices as nodes, where the network devices may include user clients, servers, routers and other devices. In practical applications, in order to ensure the information security of the network or network equipment, reduce the occurrence of abnormalities including information leakage, virus transmission, or illegal intrusion, or take corresponding ...

Abstract

The disclosure proposes a method, device, electronic equipment, and storage medium for identifying abnormal data, and relates to the technical field of the Internet. The method includes: obtaining log data of network device data transmission behavior, the log data including the data identifier of the data transmitted by the network device, and according to the abnormal information file corresponding to at least one abnormal type in the preset abnormal data rule base, Whether there is an abnormal field matching the data identifier is sequentially matched by a deterministic finite automaton DFA, wherein the abnormal information file includes at least one abnormal field, and if there is an abnormal field matching the data identifier, determine the The data corresponding to the above data identifier is abnormal data. The disclosure can not only efficiently determine whether abnormal data is transmitted in the data transmission behavior, but also determine the specific abnormal type of the abnormal data, effectively ensuring the information security of the network / network equipment.

Description

technical field [0001] The present disclosure relates to the technical field of the Internet, in particular, to a method, device, electronic equipment and storage medium for identifying abnormal data. Background technique [0002] With the development of Internet technology, the network has been gradually applied to all aspects of human society. The network may include multiple network devices connected through communication, and data transmission can be performed between the multiple network devices. However, since risky abnormal data may be transmitted during data transmission, thereby endangering the information security of the network or network equipment, how to ensure the information security of the network and network equipment has attracted more and more attention. [0003] In the prior art, a network device can authenticate a network device that performs data transmission with the network device, so that data transmission can only be performed with a safe and relia...
