Security Challenges in Recent Internet Threats and Enhanced Security Service Model for Future IT Environments

Abstract

Due to the development of ICT ( internet communication technology), people are currently able to access to the Internet and use service at any time with any types of devices. Especially, the global distribution rate of advanced Internet device and technologies as well as Internet utilization has been continuously increasing. However, various types of Internet threats have emerged in proportion with the development of Internet technology. Not only particular targets but also mass unknown targets in Internet infrastructure have been continuously threatened. However, existing Internet security system has not been able to appropriately cope with them that caused devastated damage. In this paper, we analyze the recent Internet security threats and discuss security requirements. In addition, we propose an enhanced security service model for establishing the secure Internet environment to solve aforementioned issues in future ICT.
