This is something you can do by following an example of a training for newbies. You need to explain how one should handle information, why there is the need to keep it confidential, how a person should treat confidential documentation, etc. Secure handling of information is vital for every organization. You should be familiar with main laws and rules, regulating the issue, for example, like in this essay. You are free to think of obvious things: how can you explain the importance of securing data within the organization, which examples will you give and so on. I can also recommend a paper on Securing online data, for it is also getting more and more important, especially in business.
