Making an attack on a data center becomes easier when there are loopholes in the security mechanisms that are used in data centers. In this paper the authors describe about the existing security mechanisms which are specific to the physical data centers. Furthermore, this paper has discussed the possible solutions that can be used to ensure the security of data centers as a perspective to the current Information Technology (IT) industry.
