With data centers having undergone significant transformation over time, data center security is very different from what it was years ago. For instance, while the traditional data center provided raw computing controls, next-generation data centers need to be responsive and service oriented providers of IT utility. Today, organizations also use a tiered approach to categorize data center services, based on the availability of data.
Additionally, in the case of a traditional data center, there were limited internet breakout points. Hence, data coming from outside could only move inside the data center through those limited internet breakout points. Today, however, the organization's data resides at various locations, sites, and locations, making it imperative for data centers to be available 24x7x365 to support employees, partners, and vendors. This makes the responsibility of securing the data even more difficult. In fact, data center security has become similar to defending a castle or securing an airport from external threats.
This paper offers a high-level overview of the key trends and technologies that are shaping today's data centers and their impact on data center security. It also provides a framework to achieve next-generation data center security.
