E Enable Soft Delete for Backups: Soft delete adds an additional layer of protection for your backup data. Even if a backup is deleted (whether accidentally or maliciously), it is retained for an additional period (14 days by default for Azure VMs and 30 days for Azure Blob Storage). During this retention period, the backup data can be recovered, ensuring that you can restore from these backups even if they are targeted in a ransomware attack.

B. Require PINs for Critical Operations: This control adds an extra layer of security by requiring a PIN for critical operations, such as deleting backup data or changing backup configurations. This can prevent malicious actors from easily performing destructive actions, even if they have compromised your environment. It's a form of multi-factor authentication that ensures only authorized users can perform sensitive operations on your backups.
