Any law firm intranet and/or document management system contains confidential documents not meant for general consumption. Any micreant can gain valuable information by simply sitting down at a computer connected to a law firm's network. Accordingly, all workstations on the network should be secured.
This raises an interesting problem for law firm libraries. Often libraries will have computers available for Lexis/Westlaw instruction, online catalog access, and other services. Sometimes these computers are in the line of sight of library staff. Other times they may be tucked into a quiet corner. They're intended to use by the attorneys and staff, but how can we be sure that a vendor, client, opposing counsel, or even the janitor aren't viewing information that they shouldn't?
