Auditing a POS System

Abstract

This chapter examines the structure, auditing, management, and business impact of point-of-sale (POS) systems. With the increasing use of payment cards, POS systems have become indispensable in various industries. Ensuring the security and efficiency of these systems is crucial. Emphasizing access control and user roles, this study highlights the importance of safeguarding sensitive data and maintaining data integrity. Compliance with regulations for personal information and credit card transactions is vital to protect consumer data. Frameworks like SANS Institute-CIS Security Controls and PCI-DSS are analyzed for fortifying POS systems. Implementing these frameworks ensures adherence to strict information security standards and seamless operations. Through an in-depth analysis of POS systems and associated frameworks, this research provides valuable insights into their structure, functionality, and security measures. Practical recommendations strengthen POS system security, protecting data and optimizing efficiency.
