The launch of the "two courses" in the new semester has profound significance. This education is not only for students, but also a knowledge popularization for the general public about cherishing life and avoiding risks. The rampant ice and snow disasters, the Wenchuan earthquake, and successive natural disasters have caused us enormous loss of life and property, and also reminded us to prepare early, cherish health, and protect life.
There are risks in the real society, and there are also risks in the virtual society built by information and information systems. When we plan, build, and apply information systems, we must also have risk awareness and establish security strategies. We must also strengthen daily "exercise" against risks, so that the physique of the information system becomes stronger and plays its due economic and social benefits.
