20220159030
A claim for priority under 35 U.S.C. § 119 is made to Korean Patent Application No. 10-2020-0155163 filed on Nov. 19, 2020 in the Korean Intellectual Property Office, the entire contents of which are hereby incorporated by reference.
The present disclosure relates to an Internet Protocol (IP)-based security control method and a system thereof.
Recently, cyber security threats have been increasing, along with an increase in Internet services, and thus the need for security control in response is increasing. In particular, security control is essential for Internet service companies.
However, as the response time for cyber security threats increases with the continuous security threats and the increasingly intelligent forms of cyber threat, it is insufficient to deal with these threats with existing manpower, and inefficient situations are occurring. The need for security control is growing in both domestic and foreign cyber security markets, but it is not easy to proceed due to the cost burden.
Also, there are frequent cases of (bad actors) using a phishing site by creating a domain similar to a company's internet service domain, and the case of using the company's internet service IP address as a malicious code spreading site is increasing. Accordingly, it is necessary to determine whether a company's IP address has been abused by malicious code/phishing.
In particular, in recent cyber attacks, the spread of malicious codes through websites with many user accesses is used as the main spreading route. After a hacker hacks a website with a lot of user access, a malicious script with an attack code for vulnerabilities may be hidden therein. When a user in a personal computing environment with vulnerability accesses a forged website, a malicious code is downloaded and installed on the personal computer, which is then infected with the malicious code without the user's awareness.
The number of new malicious codes created by hackers for financial gain increases exponentially every year. Thus, with only the antivirus method, which is the existing endpoint security technology that only protects against presently known malicious codes, there is a limit to protecting a company or institution from the risk of being infected with new and variant malicious codes through forged websites.
In addition, the network security method, which analyzes packets flowing into the network to identify malicious codes, has a very high detection rate of false positives due to numerous normal file packets, which imposes a heavy workload on security system operators. Hence, it is very ineffective to use as a response technology for intelligent persistent threats through websites.
For this reason, even though a solution known as a vulnerability scanner is used, it simply finds a number of vulnerabilities and notifies an administrator thereof. The administrator cannot obtain any information on which vulnerability to solve first. Furthermore, manual analysis that takes several weeks or several months needs to be performed to obtain such information.
However, even after spending a lot of time and money to perform analysis, it is practically impossible to solve all discovered security vulnerabilities. Hence, the security level is gradually decreasing despite management of the vulnerability.
Therefore, there is a need for specific and clear analysis reports and solutions that can reduce security damage caused by vulnerability in corporate IT assets.
The above information described in this background section is only to enhance the understanding of the background of the present disclosure and therefore it may contain information that does not form the related art that is already known to a person having ordinary skill in the field to which this technology pertains.
An aspect of the present disclosure is directed to providing a security control solution that accurately and efficiently identifies security risk factors based on IP, and quickly provides the identified security risk factors to an administrator, so that the administrator can preemptively respond to the detected risk IP and malicious code on a web site.

In one embodiment, in the selection of the target IP address, an IP address of the similar domain is selected as the target IP address.
The method according to an embodiment further includes: storing the IP monitoring information in a database; and classifying and storing the IP monitoring information according to a presence or absence of the banner information, a presence or absence of the malicious code information, and a presence or absence of the similar domain.
