Which strategy can enhance the resiliency of the backup process to mitigate ransomware attacks on Azure Virtual Machines?

Requiring PINs to disable backups is a strategy that helps enhance the resiliency of the backup process specifically in the context of protecting against ransomware attacks. By utilizing a PIN, you add an additional layer of security that prevents unauthorized users from disabling or altering the backup configuration. In the event of a ransomware attack, this means that even if an attacker gains access to the Azure Virtual Machine, they would not be able to easily take down the backups, which are crucial for data recovery.

This measure ensures that the backup process remains intact and operational, allowing for continuity of data restoration efforts and minimizing the potential of permanently losing access to critical information. It adds a crucial authentication component that can safeguard against malicious actions, which is particularly important in the landscape of increasing cyber threats where ransomware attacks are a common concern.

While daily backup schedules, multi-region replication, and encrypting backup data are essential aspects of a comprehensive backup strategy, they do not directly address the vulnerability of backup administration and control points as effectively as implementing a PIN. Thus, requiring PINs aligns specifically with enhancing the direct security of backup processes against unauthorized changes that could result from a ransomware attack.
