What is/are: New in NSS 9.7 SR5 (Release Notes)


  • Improved resolution of quota target paths for NetApp environments
    NSS 9.7 SR5 introduces an improved method of registering with NetApp CIFS servers to receive notifications of file system changes. Now NSS registers to receive notifications at the root-most level, this significantly reduces the number of scenarios in which the same FPolicy notification must be sent to NSS multiple times. In addition, NSS will now confirm that its service account has access to the paths where it registers to receive change notifications (root-most paths, not individual quota paths) - increasing resilience.
  • Support for quota policies on NetApp CDOT v9.x
    In default configuration NetApp Clustered Data ONTAP version 9.x includes "admin$" as part of the path in FPolicy notifications. NSS was previously unable to resolve these paths correctly, leading to quotas falling into an invalid state. NSS 9.7 SR5 is required for customers using NetApp CDOT version 9.x.
  • Tracing denied file operations - alerting of active malware
    NSS quota and file blocking features are used to deny file operations. Recently Northern was asked to provide the ability to send reports to administrators that listed all file operations that were denied within a time interval. Specifically, one customer was looking to first block specific file extensions linked to known malware and then report all renames that were attempted during each five minute window - enabling administrators to first prevent files from becoming encrypted and to immediately identify when, where and through which accounts attempts to encrypt were being made. Contact your Account Manager or sales@northern.net for more information about this use case.
