6.      Encrypt Sensitive Data

• Protect Data at Rest: Safeguard stored data by encrypting it, rendering it unreadable even if storage is compromised.
• Data Encryption in Transit: Ensure the secure transfer of sensitive data over networks using encryption.
• Key Management: Manage encryption keys securely, considering the use of hardware security modules (HSMs) for storage.
• Choose Strong Encryption Algorithms: Opt for established encryption algorithms like Advanced Encryption Standard (AES) or RSA for robust security.

7.      Employ a Comprehensive Data Backup and Recovery Plan

• Establish a Regular Backup Schedule: Implement a backup schedule tailored to your organization’s needs.
• Choose Suitable Backup Methods: Select appropriate backup methods such as snapshots, replication, or traditional backups.
