Computer security protection system based on big data

Abstract

The invention discloses a computer security protection system based on big data, and the system comprises a program extraction module which is used for intercepting a program which needs to pass through a firewall; a keyword extraction module which is used for extracting keywords from an original program text through a keyword extraction algorithm; a data summarization module which is used for arranging the keywords extracted by the keyword extraction module according to the appearance sequence of the keywords in the original program text to obtain character strings; a result judgment module which is used for inputting the character string into a support vector machine and outputting a result whether the character string passes through a firewall; and a result execution module which is used for controlling the firewall to allow the program to pass according to the firewall passing result. The method comprises the following steps: extracting a program to pass through a firewall, converting the program into a text format, extracting keywords in a text, arranging the keywords into numerical values in a character string form, sending an array into a support vector machine to obtain a result whether to pass through the firewall, and executing the result.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a computer security protection system based on big data. Background technique [0002] In the field of information security, firewalls are usually set up for virus protection, so that only data flows that comply with security policies can pass through the firewall. In order to achieve better protection effect, it is necessary to update the firewall's memory virus database in real time. However, this requires higher and higher computer configurations and larger storage capacity, so that the demand for virus database storage can be met. At present, users generally pursue self-use space, and the increasingly large virus database will reduce the free space that users can use freely, thereby reducing user experience. Contents of the invention [0003] The purpose of the present invention is to overcome the problems in the above-mentioned prior art, and provide a compu...
