This chapter explains advanced data protection and encryption. It takes after Chapter 3 , which introduced advanced IAM management strategies. The chapter enlists the management of encryption to assist in handling widely used GCP services such as Cloud Storage, Spanner, and BigQuery. It evaluates the nature of their services and configuration to enable a safe and secure environment for data management. Additionally, the chapter looks into the probable future of encryption, looking into post-quantum cryptography (PQC), which moves alongside the quantum computing advances. This chapter argues that, with the shift in GCP, there are different strategic advances to ensure data protection keeps up with advancement in technology, thus ensuring security at all levels. After you read this chapter, you will understand the strategies needed to leverage GCP’s data protection at an advanced level, ensuring that encryption features can be applied to secure your data.
