A security analyst is tasked with implementing a log management strategy for a medium-sized enterprise that handles sensitive customer data. The organization is required to comply with regulations such as GDPR and PCI-DSS, which mandate specific retention periods and access controls for log data. The analyst decides to categorize logs into three types: system logs, application logs, and security logs. Each type of log has different retention requirements: system logs must be retained for 1 year, application logs for 6 months, and security logs for 2 years. If the organization generates an average of 500 MB of logs per day across all categories, calculate the total storage requirement for each log type over their respective retention periods. Additionally, determine the total storage requirement for all log types combined over the entire retention period.
