The course I am in charge is "Information Security". In the construction and operation of information systems, networks and security are like two complementary wheels of a car. With networking, the convenience of information systems increases. However, in proportion to that, security risks also increase. In order to build and operate an information system optimally, it is important to always keep the balance in mind. In addition, network technology and security technology are evolving day by day in competition with each other. Along with the progress of information systems and the expansion of their use, networks are becoming faster, and more broadband is in use day by day. Under the slogan "ubiquitous network society", everything is going to be networked. Not only cars and information appliances, but also a radish and even a refrigerator to store it are connected to the network. On the other hand, as exemplified by cloud computing, data has been increasingly concentrated to a data center of software applications, rather than hardware or platform, on the premise of the existence of high-speed and broadband networks. Users can use computing resources through the network like they use electricity and water.

Of course, such a service environment can be realized with strong information security. The scale of damage caused by personal information leakage, computer virus infection, web server intrusion and page rewriting, e-commerce fraud, etc. is also increasing in proportion to the progress of networking. However, going back to the era of "close borders" is no longer a realistic solution. That's why we need a balanced solution for our situation. It's easier said than done, but it is unavoidable.

I would like to encourage all students to take on the challenge of mastering the latest network and information security technologies while balancing both theory and practice. And keep in mind that it's humans who use technology. There are growing new trends of legal issues regarding copyrights, the convergence of broadcasting and communications, and on-demand content distribution. I hope that you will have an opportunity to think about the role that information communication technology and information ethics play in the social system.
