With data centers able to store even exabytes of data (with one exabyte equivalent to 250 million DVDs of data), a tremendous risk is incurred just simply by storing the data. Results would be catastrophic if this sheer amount of data were to fall into the wrong hands. Sensitive information like credit card numbers, confidential business files, medical records, and more could be leaked online for all to see if someone with ill-intentions were to gain unauthorized access to a data center. Many large organizations erect their own data centers, so a breach of their information would put the success of their company at risk and would compromise all of their employee records, trade secrets, and financial reports. Sure, it is possible for a hacker to access data center servers remotely, but given access to the servers themselves, a hacker could simply plug-in and start stealing data. So, implementing cybersecurity is only one part of the puzzle–data centers should have strong physical entrance security.
