It is no longer a question of *if* you will face a ransomware attack, but *when*. Modern ransomware strains are highly sophisticated, often dwelling in your network for months to locate and encrypt your local and cloud backups before triggering the ransom demand.
Immutable Backups
The only defense is immutability. An immutable backup cannot be altered, encrypted, or deleted by anyone - not even a system administrator with root access - for a set period. Coupled with physical or logical air-gapping, this ensures that no matter how severely your primary network is compromised, your data remains secure and recoverable.
