Problems solved by technology
[0002] With the continuous development of network technology, it has become very common for users to log in to service devices through the interface to obtain corresponding content. However, the development of network technology also affects network security. When users obtain content through the interface, on the one hand, the input content There is no problem in itself, but it may be hijacked by attackers to obtain content and attack service equipment. On the other hand, illegal users directly conduct network attacks, which poses a security threat to content servers. Therefore, how to use user behavior track information To identify the legitimacy of the content it acquires, and after acquisition, it can also find out whether there is a security threat in the server in time, which becomes a technical problem to be solved by the present invention

Embodiment Construction
[0030] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, rather than for limiting the protection scope of the present invention.
[0031] like figure 1 As shown, the present invention proposes a zero-rule attack detection method based on semantic context, which specifically includes the following steps:
[0032] Step S101. Receive a service query request input by a user.
[0033] In this step, before receiving the service query request input from the user, pre-establishing semantic context matching data based on the user's behavior footprint is included. In the present invention, a semantic-based context matching mode is set, and each time a user accesses the server to obtain a content request, traces and user information will be left, and the legal or illegal ones will be stored locally. A se...

The present invention proposes a zero-rule attack detection method based on semantic context, including: receiving a service query request input by a user; parsing the content of the query request, and fetching content query conditions and constraint conditions; when the query conditions are met, then Access to the content acquisition channel is allowed; otherwise, the constraint condition is set in the content to enter the content acquisition channel; wherein, the query condition is a preset rule of semantic context; the constraint condition is a zero-rule vulnerability detection rule. The semantic context-based zero-rule attack detection method of the present invention makes content acquisition more secure and more efficient through the detection modes set by various conditions at the server end. In addition, the invention also discloses a semantic context-based zero-rule attack detection device.
Description
technical field [0001] The invention belongs to the technical field of information security detection, and in particular relates to a zero-rule attack detection method and device based on semantic context. Background technique [0002] With the continuous development of network technology, it has become very common for users to log in to service devices through the interface to obtain corresponding content. However, the development of network technology also affects network security. When users obtain content through the interface, on the one hand, the content they input There is no problem in itself, but it may be held hostage by attackers to obtain content and attack service equipment. On the other hand, illegal users directly conduct network attacks, which makes the content server a security threat. Therefore, how to use user behavior trajectory information To identify the legitimacy of the acquired content, and to find out whether there is a security threat in the server...
