What is the purpose of data encryption at rest?

The purpose of data encryption at rest is specifically to protect stored data from unauthorized access. This form of encryption ensures that even if someone gains access to the physical storage media, the data remains unreadable without the appropriate decryption keys. This is crucial for maintaining the confidentiality and integrity of sensitive information, such as personal data, financial records, or proprietary business information, thereby preventing data breaches and unauthorized disclosures.

While options related to internet speed, regular backups, and data transfer rates are important aspects of data management, they do not directly relate to the core function of data encryption at rest. Encryption is primarily focused on securing stored data, making it inaccessible to those who do not have the right permissions or credentials.
