ABSTRACT

As the digital information society advances and Internet use becomes more widespread, the importance of security continues to grow. In 2021, a company suffered a server breach due to the hacking of its external messenger, email. This incident led many companies to adopt in-house messengers to enhance work efficiency and security. However, some small and medium-sized enterprises (SMEs) still rely on external messengers due to implementation difficulties. In particular, SMEs in the semiconductor industry—a key sector in South Korea—face high risk of technology leaks during a cyberattack. This paper proposes a messenger system for SMEs that configures a server within the internal network, allowing access only in an environment isolated from the external network. This system is designed to allow access only to those with the same network bandwidth, physically blocking the risk of external hacking and providing an efficient security solution that can prevent information leaks at low cost.
