Network security detection method and device

Abstract

The invention provides a network security detection method and device, and the method comprises the steps: monitoring the flow in a preset network range, and obtaining a URL (Uniform Resource Locator) pointed by the flow; before the URL is added into a URL set waiting for security detection, determining that the URL is an effective URL; or the URL is not included in the URL set; or the URL is not subjected to security detection; determining a priority for performing security detection on the URL; according to the arranged priority, performing security detection on the URL; classifying positive and negative URLs corresponding to the traffic; aiming at the front URL, rearranging the flow quantity of the URL; aiming at the bad URL, determining all webpages of the URL, and informing a user through a popup window mode; according to the flow quantity of the rearranged URLs, implementing network bandwidth resource redistribution; and clearing out the network system. The method has the advantages that the website utilization rate is increased, more network space is released, and the network environment is purified.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a network security detection method and device. Background technique [0002] With the development and wide application of Internet technology, it has brought a lot of convenience to people's life, and computer network has been closely related to people's life, so computer network security has received more and more attention and attention. [0003] At present, computer website pages are full of various bad information, including text, links, and source codes, which bring great harm to computer users, especially immature teenagers, and are not conducive to the physical and mental development of teenagers. In the prior art, security detection methods for websites are all based on crawler technology to capture Uniform Resource Locators (Uniform Resource Locators, URLs), and then perform security detection on webpages corresponding to the captured URLs to discover these pot...

Problems solved by technology

But this method has some problems: (1) not inform users of bad websites through pop-up windows or short messages, and use anti-virus software to remove bad websites, so as to increase network space to serve other websites and purify the network environment; (2) ) does not reallocate network bandwidth resources based on the amount of traffic corresponding to the URL monitored within a predetermined time frame, thereby increasing website utilization
