Data encryption standards are the best information security initiative for creating an enterprise strategy for protecting data across multiple data repositories and different departments because they help to ensure the confidentiality, integrity, and availability of data in transit and at rest. Data encryption is a process of transforming data into an unreadable format using a secret key or algorithm, so that only authorized parties can access and decrypt it. Data encryption standards are the rules or specifications that define how data encryption should be performed, such as the type, strength, and mode of encryption, the key management and distribution methods, and the compliance requirements. Data encryption standards help to protect data from unauthorized access, modification, or theft, as well as to meet the regulatory obligations for data privacy and security. Therefore, data encryption standards are the correct answer.
