Ransomware attacks have evolved significantly over time, becoming more sophisticated to stay ahead of the advancing cybersecurity measures. With the rise of AI, these attacks are increasingly becoming more efficient.

As reported in the latest State of Ransomware report by Sophos, more than half of organizations (59%) faced an attack in the past year. Shockingly, 63% of these organizations received ransom demands exceeding $1 million.

The use of ransomware as a method of cyber-attack isn’t new, but the innovative tactics employed for such attacks are. In fact, these attacks have increased by 18% in just the past year—an alarming trend that seems poised to continue.

To address the escalating threats of ransomware, organizations must adopt a comprehensive defense strategy. This strategy should encompass the implementation of secure storage and backup solutions, ensuring that cybersecurity remains a priority.

Many organizations are already aware of the “3-2-1 rule” when it comes to data backup, which suggests that enterprises should maintain three copies of their data on two different types of media, with one copy stored offsite to enhance protection.

However, with the rise of ransomware and various forms of cyberattacks, organizations have come to understand the necessity of keeping a fourth copy of their data. Consequently, the 3-2-1 rule has evolved to address the current threats faced today.

The updated version of the 3-2-1 rule is known as the “3-2-1-1-0 rule.” This rule indicates that organizations should now keep at least three copies of their data in addition to the original, while still utilizing two different types of backup media. These media types could include disk, tape, cloud storage, or solid-state drives (SSDs). Additionally, one copy must remain offsite, and one should be kept completely offline.

Finally, it is crucial to ensure that the original backup is free from errors, as this is essential for verifying that the correct and original data can be restored accurately.

Even AI-powered storage technologies, no matter how advanced they are, will continue to be vulnerable to the evolving methods cyber-attackers are using (after all, attackers can leverage AI to their advantage as well). This is part of the reason why offline storage is critical – organizations need to ensure a physical separation from the broader digital landscape.

Since offline storage isn’t physically connected to an organization’s network, it’s isolated from the “cyber” part of cyber-attacks, meaning that essential data backup remains inaccessible to cybercriminals. This strategy is known as “air gapping,” which gives organizations more control over the security of their data.

Tape technology is the standard offline backup method for large organizations, as it is particularly ideal for air-gapped strategies because backup data is stored on physical cartridges that are then further physically stored either in a tape library or offsite vaulting service. This creates an actual, physical air gap between the data and the network, ensuring cyber-attackers are kept away from it.

There is also the offsite object storage option, which offers an alternative way to facilitate a physical air gap while speeding up recovery times. However, unlike tape-based solutions, they do require a network connection to facilitate data ingestion and will thus require additional safeguards to ensure true isolation.

Beyond offering air-gapped backup protection from breaches, offline storage brings several other significant advantages. These solutions can help alleviate the effects of a total network failure caused by issues like hardware malfunctions or natural disasters, ensuring that a business can continue its operations smoothly with minimal interruptions.

Moreover, when data is stored offline or in a dedicated physical site, it becomes much easier to monitor and manage. In contrast to data dispersed across multiple servers and networks, offline data allows organizations to efficiently implement updates, modifications, and deletions. This approach also simplifies data recovery, as there is no assurance that cloud-stored data can be completely retrieved following a disastrous incident.

Furthermore, the rise of more advanced cyber-attacks could potentially render data inaccessible. Nevertheless, if an organization’s offline storage solution is diligently managed on an ongoing basis, this threat can be minimized, allowing organizations to feel confident that their data will always be accessible and preserved.

In a world where ransomware threats continue to change and grow, organizations must remain proactive by adopting strong, multi-faceted defense strategies.

The emergence of AI-driven cyberattacks further highlights the necessity for all-encompassing solutions that go beyond the basics, such as the 3-2-1-1-0 rule, where offline storage takes on an essential role.

By incorporating offline backups and air-gapped systems, businesses can ensure their vital data is not only protected but also recoverable— even against sophisticated cyber threats or unexpected crises. Ultimately, an anticipatory approach to ransomware defense, founded on solid storage and backup practices, is crucial for the protection of organizations both now and in the future.
