Data security in the cloud best practices include: understanding and implementing security fundamentals, abiding by the shared responsibility model, data encryption, and obeying applicable regulations.
Data security fundamentals often come back to the CIA Triad: data confidentiality, data integrity, and data availability.
The shared responsibility model refers to the idea that both a cloud provider and the organization using the cloud are responsible for ensuring the overall security of the organization’s cloud infrastructure, including the data housed there.
Data encryption is a basic element of data security that is especially important in a cloud environment. Cloud providers can offer advanced encryption tools as well as secure storage modules for cryptographic keys.
Finally, regulations around data security, and in particular data privacy, continue to evolve. Organizations should have systems in place to ensure they are always in compliance with any relevant laws and regulations.
