For retail businesses, the point of sale (POS) system is arguably their most important information technology system. The POS system not only records transactions and sends appropriate data to inventory control, fulfillment, accounting systems, etc., it must also contact financial institutions and credit card processors. The data that must be transmitted to these various systems is sensitive, private, and regulated, and therefore must be protected at all times.

A secure point of sale system will deploy procedures that encompass access controls, application controls, and data protection protocols.

This guide and the accompanying checklist from TechRepublic Premium will help you successfully secure a point of sale system for your business enterprise.
