Ransomware attackers now target backups as a priority: before encrypting production systems, they try to destroy or compromise backups to make recovery impossible. Protecting backups against ransomware relies on three fundamental principles.

  1. Network isolation of the backup vault
    An effective digital vault must never be directly accessible from production or administration networks, even during replication. Seclab Xchange’s Electronic AirGap technology ensures this permanent isolation through unidirectional or bidirectional data transfer, without any exploitable open network flow.
  2. Immutability of stored data
    Once stored in the Dell PowerProtect Cyber Recovery vault, backups cannot be modified or deleted — even by a compromised administrator account. Immutability provides a final line of defense against attackers who have obtained elevated privileges in the IT system.
  3. Integrity verification before restoration
    Restoring a contaminated backup would reintroduce ransomware into a system that has just been cleaned. Dell CyberSense analyzes backup content with artificial intelligence to detect any corruption or malware injection before initiating recovery.

The Dell x Seclab solution thus ensures that backups are fully protected against ransomware attacks.
