Problems solved by technology

However, with the continuous discovery and update of vulnerabilities, the number of plug-ins that need to be used will continue to increase. Loading all plug-ins into the memory at one time will take a long time to load, slow down the entire scanning speed, and require more memory capacity, resulting in an increase in hardware cost

Embodiment Construction

[0022] figure 1 It is a flowchart of an embodiment of a plug-in scheduling method for a vulnerability scanner according to the present invention. As shown in the figure, the method includes the following steps:

[0023] Step 100, after the vulnerability scanner is started, the preset universal plug-in is loaded into the memory.

[0024] Wherein, the general-purpose plug-in refers to a plug-in whose scheduling rate is greater than a preset threshold, and the scheduling rate is a ratio obtained after statistics of a large amount of historical experience data of various operating systems, and is used as an attribute parameter of each plug-in to indicate that the How often the plug-in is called when performing a vulnerability scan. For example, if a plug-in's dispatch rate is greater than a preset threshold, it indicates that the plug-in is very likely to be called, so it should be loaded into memory.

[0025] Statistical process about the scheduling rate, such as figure 2 sho...

Abstract

The invention provides a vulnerability scanner and a plug-in scheduling method thereof. The plug-in scheduling method includes: loading a preset general plug-in into an internal memory after the vulnerability scanner is started up; recognizing the category of an operation system of a target device after receiving the vulnerability scanning task; selecting a preset scanning template according to the category of the operation system; and invoking plugs-in recorded in the selected scanning template. According to the plug-in scheduling method, the general plug-in is invoked first, the category of the operation system of the target device is then recognized, and the corresponding plugs-in are loaded into the internal memory for invoking. Compared with the mode of loading all plugs-in into the internal memory in one time in the prior art, the plug-in scheduling method shortens loading time, accordingly improves scanning speed, reduces requirements for capacity of the internal memory, and accordingly is favorable for reducing hardware cost.

Description

technical field [0001] The invention relates to a vulnerability scanner and a plug-in scheduling method thereof, belonging to the technical field of vulnerability scanning. Background technique [0002] A vulnerability scanner is a program that automatically detects security weaknesses on remote or local hosts. According to the existing operating mechanism, during the startup process of the vulnerability scanner, all the plug-ins it supports should be loaded into the memory at one time, and then these plug-ins are scheduled according to the needs, so that these plug-ins can scan the corresponding vulnerabilities during the running process . However, with the continuous discovery and update of vulnerabilities, the number of plug-ins that need to be used will continue to increase. Loading all plug-ins into the memory at one time will take a long time to load, slow down the entire scanning speed, and require more memory Capacity, resulting in an increase in hardware costs. ...
