How secure is data stored in cloud archives?

Security considerations for cloud archives

Cloud archives can be highly secure when configured correctly. Security is a shared responsibility: cloud providers offer strong infrastructure protections, but customers must manage access controls, encryption keys, and data policies.

Essential security measures:

• Encryption at rest and in transit.
• Strong identity and access management with least privilege principles.
• Role-based access controls and multi-factor authentication.
• Immutable storage options to prevent tampering.
• Detailed logging and audit trails for access and changes.

Providers typically offer redundancy and physical security at data centers, but customers should verify certifications and the provider’s incident response capabilities. Consider bringing your own keys (BYOK) for additional control over encryption.

Regular audits, penetration testing, and monitoring for anomalous access help maintain security posture. With these controls in place, cloud archives can meet or exceed the security of many on-premises solutions.
