A systems administrator at a financial services company is participating in a review of the organization's data retention policies. The company handles a wide variety of data, including customer financial transaction records, archived email, and server performance logs. Which of the following should be the administrator's MOST important consideration when defining retention periods?
The correct answer is legal and regulatory requirements. For a financial services company, compliance with regulations such as the Sarbanes-Oxley Act (SOX), Payment Card Industry Data Security Standard (PCI DSS), and various data privacy laws is mandatory. These regulations dictate the minimum, and sometimes maximum, time that specific types of data must be stored. Failure to comply can result in severe legal penalties, fines, and reputational damage. While storage costs, business needs, and backup efficiency are valid operational concerns, they are all secondary to the absolute necessity of meeting legal and regulatory obligations. The policies are primarily created to fulfill these requirements.
