The technology that enables data encryption at rest and in transit primarily involves cryptographic algorithms and protocols, such as AES (Advanced Encryption Standard) and TLS (Transport Layer Security). Data encryption at rest protects stored data from unauthorized access, while encryption in transit secures data as it moves across networks. These security measures safeguard sensitive information from breaches and eavesdropping, ensuring confidentiality and integrity. Organizations use encryption technology to comply with data protection regulations and mitigate risks associated with data theft.
