Veeam Immutable Backup and the Dwell-Time Problem
Immutability is rightly regarded as the key defense against ransomware, making backups unalterable so an attacker cannot destroy them. But there is a subtlety that can undermine immutability if overlooked: the dwell-time problem, the fact that attackers often lurk in an environment for a long time before striking, which means immutability that does not last long enough can be defeated by patience. Understanding Veeam immutable backup and the dwell-time problem is how an organization ensures its immutability actually holds against the patient attackers ransomware often involves, rather than being quietly defeated by an adversary who waits out immutability that expires too soon, a subtlety that distinguishes immutability that genuinely protects from immutability that only appears to. What Dwell Time Means Dwell time is the period an attacker spends inside an environment before launching the visible attack, often weeks or months during which the attacker explores, spreads, and prepares.
