To secure cloud storage, technologies such as encryption and access controls are often utilized. Encryption protects data by transforming it into a coded format that is unreadable without the proper decryption key, ensuring that sensitive information remains secure during transmission and at rest. Access controls help manage who can view or edit data stored in the cloud, using authentication methods such as passwords, biometric scans, or hardware tokens. Together, these technologies safeguard against unauthorized access and potential data breaches.
