Article Summary

CTERA Edge Filer version 7.6.x includes the following new features:

Ransomware Protection

Ransomware attacks have become an increasingly imposing threat to organizations. In most ransomware attacks, encryption restricts access to critical files, systems, and applications. This encryption process happens silently in the background.

Taking proactive measures against ransomware attacks helps safeguard your data and ensures the continuity of your operations. Each user’s behavior is monitored and fed in to a machine learning algorithm trained on an extensive dataset of attack flows. Via this monitoring, CTERA Ransom Protect is able to detect and block ransomware attacks within seconds.

Note

CTERA Ransom Protect monitors Windows File Sharing (SMB) traffic. It does not monitor user behavior on other file sharing protocols such as NFS or FTP.

Key Features of CTERA Ransom Protect include:

  • Real-time detection: Advanced machine learning algorithms identify behavioral anomalies suggesting fraudulent file activity, and block offending users within seconds.
  • Zero-day protection: CTERA Ransom Protect does not rely on traditional signature update services, eliminating the need for constant on-site updates.
  • Incident management: An administrator dashboard provides real-time attack monitoring, comprehensive incident evidence logging and post-attack forensics.
  • Instant recovery: Near-instant recovery of any affected files from snapshots.

In addition, CTERA Ransom Protect requires minimal configuration, requiring a single click to activate ransomware protection on the CTERA Edge Filer.

Automatic Backup of the Edge Filer Configuration

The CTERA Edge Filer configuration (db.xml) should be backed up to the CTERA Portal so that the edge filer is protected in the event of a failure or disaster, by restoring the configuration.

The configuration is automatically backed up by default.

Note

The automatic backup of the configuration requires a connection to a CTERA Portal 7.5.x or higher.

For details, see Backing Up and Restoring the Edge Filer Configuration.

New Home Dashboard

The Main > Welcome page has been replaced with a new dashboard to provide an overview of the edge filer and the activity over time.

Improved Handling of Previous Versions

New CTERA Edge Filers include an option to improve performance when connected to a CTERA Portal from version 7.5.1159.x.

To enable this feature and understand additional implications and limitations when enabled, contact CTERA Support.

Improved Eviction Policy for Deduped Files

When evicting files after deduplication has been enabled, deduped files are also included in the retention policy.

Next Generation File System

CTERA has introduced the next generation file system to support billions of files on a single edge filer with improved performance. For example, move, rename, upload operations are significantly faster.

The next generation file system requires a CTERA Portal from version 7.5.1159.x.

Note

The next generation file system is only available for new edge filer deployments and not existing deployments that are upgraded.

To enable this feature and understand additional implications and limitations when enabled, contact CTERA Support before starting to populate the edge filer with content.

Support for WORM Compliant Cloud Folders: CTERA Vault

WORM (write once, read many) compliance ensures that data cannot be tampered with or deleted. CTERA Vault uses WORM technology to prevent editing, overwriting, renaming or erasing this data.

When a cloud drive folder is defined with folder compliance on the CTERA Portal, after an initial, optional, grace period, the contents of the folder can be protected from any attempt to change the folder content such as by renaming, moving, modifying, or deleting content for a specified retention period, either on the CTERA Portal or CTERA Edge Filer.

For details, see Folder (WORM) Compliance: CTERA Vault.

Improved Security with Upgraded SAMBA version

The SAMBA version used has been upgraded to version 4.13.14. This version includes a number of security fixes.

Improved Integration with macOS Spotlight

The integration with macOS Spotlight has been improved.
