Embodiment Construction

[0016] Such as figure 1 , 2 As shown, the present invention provides a URL virtualization dynamic defense method against automated attacks. Network defense is an important content in the field of computer security. The specific content includes two steps: the client request processing step and the server response processing step.

[0017] Now suppose a client requests a certain website, and the server sends a normal access response message:

[0018] HTTP / 1.1 200 OK

[0019] Date: Sat, 31Dec 2005 23:59:59GMT

Abstract

The invention discloses a URL virtualization dynamic defense method for automatic attacks, which realizes the dynamic change of URL virtualization and thus solves the problems of unknown attacks and unknown threats in the network. The method comprises a client request processing step and a server response processing step which respectively process an HTTP message received from a client and an HTTPmessage transmitted from a server to the client. Under the premise of functional equivalence, URLs are enabled to dynamically change in a defender controllable manner and manifested to be dynamicallychanging targets which are difficult to be observed and predicted for attackers, thereby increasing the difficulty and cost of attacks against unknown vulnerabilities and backdoors.

Description

technical field [0001] The invention belongs to the technical field of network security, in particular to the field of mimic gateways, and relates to a URL virtualization dynamic defense method against automatic attacks. Background technique [0002] Traditional network defense technologies mainly include firewalls, authentication technologies, access control, virus prevention, intrusion detection, vulnerability scanning, and information encryption technologies. Most of these security defense technologies are passive defenses. Although they provide powerful protection for network information security, their inherent defects also restrict their role in today's network security construction. [0003] There are four defects in the above-mentioned network defense technology: First, the defense direction is fixed, and only the pre-configured defense points can be protected. Traditional defense mostly adopts the method of manual configuration, which is designed for the existing p...
