Claim Text:
1. An automatic malignant code collecting system, comprising: a first database configured to store detection target website information; a virtual machine hardware controller configured to read the website information from the first database and transmit the website information; a first virtual machine configured to periodically gain access to a website using the website information received from the virtual machine controller and to collect a malignant code and evidence thereof if an abnormal event occurs when the first virtual machine gains access to the website; a second virtual machine configured to periodically gain access to the same website as accessed by the first virtual machine using the website information received from the virtual machine controller and to collect a malignant code and evidence thereof if an abnormal event occurs when the second virtual machine gains access to the website; a second database configured to store the malignant code and the evidence thereof collected by the first virtual machine and the second virtual machine; and a management server configured to provide a user interface that enables a user to identify, on a website-by-website basis, the malignant code and evidence thereof stored in the second database, wherein the management server monitors security levels of the first virtual machine and the second virtual machine through an interface that makes real-time communication with the first virtual machine and the second virtual machine, and sets the security levels of the first and second virtual machines depending on a monitoring result, and the management server comprises a security support interface configured to automatically install a security patch having a latest security level in the second virtual machine while monitoring the security level of the second virtual machine, and to automatically update the security patch installed in the second virtual machine, if an execution file other than a website access program is executed in the course of gaining access to the website, namely if an abnormal event occurs, the first virtual machine and the second virtual machine recognize the execution file as a malignant code and interrupt the execution of the execution file, wherein the first virtual machine and the second virtual machine are set at different security levels, wherein the second virtual machine is set at a highest security level at which a latest security patch is installed in the second virtual machine, wherein the management server is configured to find out a latest malignant code and the evidence thereof depending on the difference between a security level set in the first virtual machine and a latest security level set in the second virtual machine and to store the latest malignant code and the evidence thereof independently of the malignant code and the evidence thereof collected under the security level set in the first virtual machine, wherein the first virtual machine and the second virtual machine which are set at different security levels are configured to periodically gain access to the same website and to collect a malignant code and evidence thereof.
