Staying on Top of NetApp CIFS Share Permissions to Minimize the Risk of a Breach

If there is an unauthorized change to share permissions on your file storage or someone has access rights to a NetApp CIFS server that they no longer need, you need to know about it. To gain full control over NetApp CIFS access, effective permissions and permission changes in order to harden your data security posture, you need three ingredients: 360-degree visibility, comprehensive reports that deliver all the important details and alerts that instantly notify you about critical events.

Monitoring NetApp NTFS permissions with native tools

One way to track changes to NTFS permissions and find out who has access to what on your NetApp filers is to enable NetApp auditing with the built-in tools. Here are the steps you’ll need to take:

  1. Determine which event IDs that you want to monitor. In this case, these events will be changes to permissions, access to shares and so on.
  2. Configure the CIFS system access control lists.
  3. Configure auditing settings to meet your auditing needs.
  4. Manage the audit log that will be generated. Since the reports are not easy to read and look more like a mountain of raw data, be ready to spend time massaging the data into a comprehensible format. And accept that you simply can’t get real-time alerts about critical changes or access events without scripting.

Alternatively, there is a much simpler way to find out what’s going on with permissions on your NetApp filers.
