The human beings are stepping into the information society. The information industry develops very rapidly, so do the hackers, trick-playing teens, exploring children, fraudsters, and serious white-collar criminals. Thus, information security becomes an impending important issue.
In case of information breach, the victims government department, an organization or an institution, or a company will inevitably suffer great or small loss. Government may be threatened with national security. Companies may lose opportunities to develop new projects. And the public's and users' confidence will be damaged.
Then how to deal with this issue? Technology is only a partial solution to information security. What's more important is that organizations and companies should promote the awareness on information security to its staff.
