Cloud computing security encompasses the practices, technologies, controls, and applications used to protect cloud computing environments. These security measures are designed to protect data, services, applications, and the related infrastructure in the cloud from both internal and external threats, while at the same time safeguarding users’ privacy and enabling and maintaining compliance with all applicable rules and regulations. While cloud computing security needs vary widely from business to business, the primary goal is the protection of data and the control of access to that data. As more and more businesses take advantage of cloud computing and enjoy the reduced cost of doing business, increased agility, and the ability to quickly scale, they must ensure that they consider security straight from the get-go and choose the right type and level of security to actively prevent data loss and leakage.
