Secure Data Storage and Transactions Logs

Data and transaction logs are stored in multi-tiered storage media. Manually moving data between tiers gives the IT manager direct control over exactly what data is moved and when. However, as the size of data set has been, and continues to be, growing exponentially, scalability and availability have necessitated auto-tiering for big data storage management. An auto-tier storage system will save the money by pulling the rarely utilized data to a lower (and cheaper) tier. However, this data may consist in R&D results, not popular but containing critical information. Auto-tiering solutions do not keep track of where the data is stored, which poses new challenges to secure data storage. New mechanisms are imperative to thwart unauthorized access and maintain the 24/7 availability. As lower-tier often provides decreased security, the company should study carefully tiering strategies.
