Online environment intelligent deployment system and method for CTF online competition platform

Abstract

The invention discloses an online environment intelligent deployment system and method of a CTF online competition platform. The system includes an online competition platform server terminal, a reverse proxy server terminal, a virtual machine management platform server terminal and several virtual machines created by means of a virtual machine management platform and used for operating a question environment; the online competition platform server terminal is provided with an environment generation module and an environment recycling module, the virtual machines used for operating the question environment are created by means of the virtual machine management platform server terminal according to question configuration information, and port proxy is conducted through the reverse proxy server terminal so that the question environment virtual machines can be accessed through the public network IP and a port. According to the system and method, real-time intelligent deployment of the question environment is achieved through the virtualization technology, the question environment is accessed by deploying a reverse proxy on a limited public network address machine, at the same time, the Internet for the question environment is configured to be independent, it is ensured that the environment can be accessed and isolated, and the safety of other property is ensured.

Description

technical field [0001] The invention relates to an online environment intelligent deployment system and method of a CTF online competition platform (OJ platform), belonging to the technical field of information processing. Background technique [0002] CTF (Capture The Flag) is generally translated as capture the flag in Chinese, which is a popular form of information security competition. The general process is that participating teams first obtain a string of strings or other content with a certain format from the competition environment given by the organizer through offensive and defensive confrontation, program analysis, etc., and submit it to the organizer. To get points. For the convenience of calling, we call such content "Flag". There are three main types of CTF competition modes, problem solving mode, attack and defense mode and mixed mode. [0003] 1. Problem-solving mode (Jeopardy) [0004] In the problem-solving mode CTF competition system, participating tea...

Problems solved by technology

This method has several disadvantages. One is that the environment needs to be re-used every time the topic is reused, and it cannot be reused effectively. Because it is a CTF security issue, each deployment requires a lot of manual time to verify and verify the environment; The environment visited by the contestants is the same environment, and there will be interference with each other. As a result, the CTF question types with interference items cannot be answered online, and the actual environment cannot be completely simulated.
