Security at Rest: Security at rest refers to the protection of data when it is stored or at rest in a storage medium, such as databases, hard drives, or cloud storage. The primary goal is to prevent unauthorized access, disclosure, or tampering of data while it is not actively being used or transmitted. Here are some common techniques used for security at rest:
Encryption: Encryption is a widely used technique to protect data at rest. It involves converting data into an unreadable format using encryption algorithms and a secret key. Only authorized users with the corresponding decryption key can access and read the encrypted data.
Access Controls: Implementing access controls, such as user authentication and role-based access control (RBAC), helps ensure that only authorized individuals can access and modify the stored data. This includes implementing strong passwords, multi-factor authentication, and restricting access based on user roles and permissions.
Data Loss Prevention (DLP): DLP solutions can help prevent data breaches by monitoring and controlling data access and movement. They can identify and block unauthorized attempts to access or extract data from storage systems.
Auditing and Logging: Maintaining detailed audit logs and monitoring system activity can help detect and track any unauthorized access attempts or suspicious activities. These logs can be used for forensic analysis and investigation in case of security incidents.
