How can archived data be protected against ransomware?

Ransomware defenses for archives

Protecting archives against ransomware relies on immutability, strict access controls, segmentation, and offline backups. Because ransomware often seeks to destroy backups and archives, defenses must make tampering or deletion impractical.

Key defenses:

• Immutable storage or object locks to prevent alteration.
• Separate credentials and least privilege for archive administration.
• Network segmentation and air-gapped or physically isolated copies.
• Regularly tested restores to ensure archives remain uncompromised.

Combine these technical measures with monitoring for unusual access patterns and a robust incident response plan. Rapid detection and isolation of infected systems limit spread and protect long-term records.
