Adobe’s Approach to Reducing Ransomware Impact Through Advanced Backup Strategies

To address these challenges and enhance its ransomware resilience, Adobe implemented a comprehensive, multi-layered backup strategy. The key components of Adobe’s approach include:

1. Adoption of Immutable Backups

One of the foundational elements of Adobe’s backup strategy is the use of immutable backups. Immutable backups are stored in a way that prevents them from being modified, deleted, or encrypted by ransomware or malicious actors.

• Immutable Cloud Backups: Adobe leveraged cloud-based storage solutions with built-in immutability features. These backups could not be changed or overwritten once created, ensuring that they remained available even in the event of a ransomware attack.
• Write-Once, Read-Many (WORM) Storage: Adobe implemented WORM storage, which ensures that data can be written only once but read many times. This further prevents ransomware from tampering with backup files.

Key Features of Immutable Backups	Description
Cannot be Modified or Deleted	Backups are stored in a way that prevents ransomware from altering or encrypting them.
Secure Cloud Storage	Data is stored in cloud environments with immutability settings, ensuring long-term protection.
WORM Storage	Write-Once, Read-Many storage prevents unauthorized changes to backup data after it is written.

2. Multi-Region and Multi-Cloud Backup Strategy

Adobe implemented a multi-region and multi-cloud backup strategy to ensure redundancy and resilience across its infrastructure. This approach reduces the risk of a single point of failure and ensures that backups are available even if one region or cloud provider is compromised.

• Geographical Redundancy: Adobe’s backup data is replicated across multiple geographical regions. This ensures that even if a ransomware attack affects one region, data can be restored from another unaffected region.
• Multi-Cloud Strategy: By storing backups across multiple cloud providers (e.g., AWS, Azure, Google Cloud), Adobe minimizes the risk of vendor-specific outages or vulnerabilities impacting its entire backup system.

Redundancy Approach	Description
Multi-Region Backups	Data is replicated across multiple geographical regions to provide redundancy and resilience.
