Meaning
Immutable storage enforces write-once semantics so data cannot be changed or deleted for a defined retention period. The consensus view is that immutability is now a baseline requirement for backup and log data in the face of ransomware and insider threats. It is typically delivered via WORM technologies, locked snapshots or cloud object locks, and must be combined with strong authentication and key management to be effective.
Why It Matters
Immutable Storage is important in modern data and cyber resilience because it shapes protection, monitoring and recovery design.
