Callback Security.

This column will highlight some of the most significant events taking place in the world of new products directly geared to users of computer systems. As the publisher of ISPNews—INFOSecurity Product News, I have the opportunity to learn about the latest products having an impact on the information systems community. In this regular column, I will select a category of products and report on their distinguishing features. In addition, I will discuss areas of high risk that should be reviewed by those with responsibility for information security and asset protection. In this inaugural column, I review several of the latest products designed to protect microcomputers, local area networks, and mainframes from unauthorized access through dialin communications lines. These products have not been tested and the author does not claim that they actually perform as the vendor indicates.
