Service or cloud computing offers significant cost and scalability benefits for businesses. Businesses leveraging service based information technologies must mitigate privacy, security, and portability risks. The risks are manageable and, in light of the benefits, businesses should pursue a cloud computing strategy where feasible.
Cloud computing, also known as grid or utility computing, is a disruptive technological model for delivering information technology services. By providing elastic, scalable, pay-as-you-go services, cloud computing providers enable organizations and individuals to develop and deploy information systems without the costs associated with traditional information technology. However, the utilization of cloud computing services introduces unique security risks. A literature review is performed to survey current research regarding cloud computing security threats and technologies that may mitigate the risks.
Ten to fifteen years ago, the security threats to information systems were primarily mischievous in nature. Malicious elements focused on defacing web sites and hacking into computers as a demonstration of technical skill. The most damaging malware of the previous decade was simply destructive in nature, deleting data or denying service. Modern malware is much more insidious, seeking to compromise systems and stealthily steal valuable information. Modern security threats are primarily an organized criminal activity that is focused on making money through the sale of illicitly acquired information.
