Abstract

The invention discloses a method for defending cross-site request forgery attacks. The method comprises the steps of: receiving a request packet Hypertext Transfer Protocol Http requests; message requesting source to obtain the domain from where the request; if the source of the request is located field is empty, it is determined that the hypertext transfer protocol Http request is unsafe; domain if the request source is located is not empty, then the field is determined according to the request source where the hypertext transfer protocol Http request is security. Therefore, the defense cross-site request forgery attack the present application provides a method of defense can effectively cross-site request forgery attacks.

Description

technical field [0001] The present application relates to the field of network security, in particular to a method and device for defending against cross-site request forgery attacks. Background technique [0002] With the application of the Internet more and more widely, Internet security has become a problem that people pay more and more attention to. Among the various existing attack methods that threaten network security, Cross Site Request Forgery (CSRF, Cross Site Request Forgery) attack is a difficult and dangerous attack method that is difficult to prevent. The cross-site request forgery attack is mainly that the attacker uses the user's login information on a website to send a request from any website to the website. Such as sending emails, modifying information, purchasing goods, etc. in the name of the user. The following will detail the cases of bank accounts being maliciously transferred: [0003] If a user logs in to online banking to check his deposit balan...
