CISSP study material · question 462 of 500

A team proposes moving all backups to immutable cloud storage as a complete answer to ransomware. Which two cautions does CISA raise? Choose two.

  1. Immutable storage cannot be encrypted, so data is exposed to the provider.
  2. Immutable storage does not meet the compliance criteria of certain regulations.
  3. A misconfiguration of immutable storage can impose significant cost.
  4. Immutable storage requires a separate environment to be maintained alongside it.
Show the answer

Answer: B. Immutable storage does not meet the compliance criteria of certain regulations.
C. A misconfiguration of immutable storage can impose significant cost.

Immutable storage protects data without a separate environment, but CISA cautions that it does not satisfy some regulations and that misconfiguration can prove costly.
