Regular database backups are essential to protect your business from ransomware and system failures. However, backup files are prime targets for cybercriminals. If a backup file is stored unencrypted in an open cloud storage bucket, your entire customer database is exposed.
The Principle of Secure Storage
To secure your database backups, implement these fundamental steps:
- Local Encryption: Always encrypt backups locally before transmitting them to the cloud. Use robust encryption methods like AES-256 via tools like GPG.
- granularity Access Rules: Set up strict access policies for your backup storage buckets. Never use public access or shared credentials; use temporary IAM roles instead.
- Immutable Backups: Configure write-once-read-many (WORM) storage, ensuring backups cannot be modified or deleted by ransomware, securing your disaster recovery pipeline.
