An organization has established a policy prohibiting ransom payments if subjected to a ransomware attack.

When an organization has a policy prohibiting ransom payments in the event of a ransomware attack, the most effective control to support this policy is creating immutable backups. Here’s why:

Immutable Backups:

Definition:Immutable backups are backups that cannot be altered, deleted, or modified in any way once they are created. This ensures that a clean, untampered copy of data is always available.

Protection Against Ransomware:Ransomware attacks typically encrypt data and demand a ransom to decrypt it. With immutable backups, the organization can restore the affected systems using the backup without paying the ransom, thereby adhering to their policy.

Effectiveness:

Restoration Capability:Immutable backups provide a reliable means to restore data to its state before the ransomware attack. This restoration capability negates the need to consider paying the ransom to regain access to encrypted data.

Compliance with Policy:By having a secure and untouchable backup, the organization ensures compliance with its no-ransom policy as it can recover operations without engaging with the attackers.

Comparison with Other Options:

Vulnerability Scanning:While important, this primarily helps in identifying vulnerabilities and does not directly help in data recovery post-ransomware attack.

Patching:Regular patching reduces the risk of ransomware infection but does not aid in recovery if an attack occurs.

Intrusion Detection:Continuous monitoring can detect ransomware activities but does not provide a solution for restoring data after an attack.
