Multi-layered security protection

Your data,
Securely under control

QNAP combines snapshots, storage immutability, and Airgap+ isolated backup to build a three-layer protection barrier. Even under ransomware attacks, your critical data remains intact and undamaged.

The threat of modern ransomware

Ransomware no longer just encrypts your files; it will steal administrator privileges, delete all backups, and then start encrypting.

1

Lateral movement

Hackers use stolen administrator credentials to laterally move within the network, gradually expanding their control.

2

Backup deletion

Traditional backups cannot defend against attackers with administrator privileges; all copies can be deleted.

3

Comprehensive encryption

Once the backup is wiped, hackers begin encrypting all data, leaving the enterprise in a desperate situation.

QNAP Three-layer Defense Architecture

Snapshots, immutable storage, and physical isolation—three layers of defense working together to ensure your data can be safely recovered under any circumstances.

Layer 1: Snapshot Protection 123

Instantly create data snapshots to record the status at every moment. Locked snapshots cannot be deleted by ransomware. Learn more »

Layer 2: Immutable storage

Backup data is locked immediately after being written, and no one (including administrators) can modify or delete it. Learn more »

Layer 3: Physical isolation

Airgap+ achieves physical isolation through QNAP Router or Switch, remaining completely offline under normal circumstances and only connecting temporarily during backup. Learn more »

Real-World Case Study: Ransomware Attack on a U.S. Educational Institution

When attackers obtain the highest privileges, what is truly the last line of defense to protect data?

1

Attackers obtain administrator privileges

Through account leakage, internal environment intrusion, or phishing, attackers obtain legitimate high-level privileges credentials. Traditional antivirus and firewalls cannot prevent logins with a “legitimate identity.”

2

System and backups are damaged

Attackers perform destructive operations on the system, applications, and Virtualization environment on NAS. The system data is encrypted, and multiple key services cannot operate normally.

3

Immutable storage saves the enterprise

With QuObjects Object Lock (WORM immutability storage), backups data cannot be deleted or encrypted. Enterprises can quickly restore their original systems without paying ransom.

The core facts revealed by this case

The limitations of traditional protection

Accounts may be stolen, privileges may be compromised, and attacks often come from “legitimate identities.” Traditional antivirus and firewalls cannot defend against them.

The real line of defense

An immutable (Immutable) backup architecture—even if privileges management is compromised, backups still cannot be deleted, modified, or encrypted.

The true value of backups

It's not about “can or cannot restore”, but about “whether it has been successfully retained”. It must remain valid even in the worst-case scenario.

Why are isolated backup and immutable storage so crucial?

Physical isolation

Backup NAS is completely offline during normal times, making it impossible for attackers to access via the network. Even if the main system is compromised, the backup remains secure.

Immutable storage

Combining Object Lock and WORM mechanisms ensures that backup data cannot be deleted or modified during the retention period.

Fast recovery

Even in the event of an attack, enterprises can quickly redeploy systems and restore complete backups, minimizing business interruption.
