Another area of concern is recycle bins or regular trash containers. These are better than a magazine stand. You can browse all you want, and you never have to buy anything. The bottom line is that once your trash leaves the office, it becomes public information for anyone who is interested. So you have to be careful about what type of information is sent out in the regular trash.
Fax machines pose another security problem.

The attached information may be confidential. If you have received this fax in error, please destroy the document and notify the sender of the error.
