I am reviewing a design document for a law enforcement system. The customer wants to use dialup and the internet for its communications and data base maintenance. The staff in the field will enter information into the system and recieve information. I am bothered by the dialup aspects given the confidentality of the information that can be accessed but I do not know enough about current technology to know if I should be concerned? Any suggestion of material I could use to research the issues would be appreciated.
