As various forms of information are spreading across the world, many diverse forms of businesses and activities are springing up to make use of them. In recent years, we have encountered different types of information security problems including targeted attacks against specific corporate organizations, phishing, information leakage, and cyber attacks against interested nations. It is difficult to see IT progress without solutions of these problems. IISEC was established in 2004 as a graduate school specializing in information security, and ever since then, we have devoted ourselves to advanced education and research under the slogan, “systemizing a new study field and fostering specialists.” Eventually, we have structured our curriculum consisting of cryptography, network system, system technology, operation, law and ethics to be competitive in the world. Moreover, we never stop brushing up our curriculum to cultivate talents.
