Government laws and industry regulations in the United States and around the world mandate protection of sensitive data. Data must be secure when at rest, during transactions and when it transverses network connections. Each industry has specific regulations, which are commonly used in data centers and should be used in the cloud as well. Whether cloud encryption is demanded by your government, your industry, your customers, or simply your own good business sense – it is a best practice for any business that operates in the cloud.
Encryption is more important in the cloud than in the physical data center. This is, quite simply, because clouds do not have walls like data centers do. Encryption is an excellent solution for creating a mathematical replacement for physical walls – keeping data secure and private, and keeping the bad guys out.
