Configure CIFS Auditing

This article applies to: Shared File Services

CIFS auditing is only required for shares which store Confidential or HIPAA data. Only properly configured shares on SFS are allowed to store Confidential data. These shares include a separate volume for the CIFS audit log.

  • You Configure CIFS Auditing for the share you requested, \\\CIT\Employee-Data.
  • The resultant CIFS Audit Log files are automatically stored on the Audit Log Share, \\\CIT\Employee-Data-auditlog.
Do not configure CIFS Auditing for the Audit Log Share itself, \\\CIT\Employee-Data-auditlog.
  • If not already done, Map a Network Drive using your "doc" account.
  • Right-click on the top-level folder of your share, select Properties, Security, Advanced, Auditing.
    At this point existing Auditing configurations are displayed; you can edit, or add new configurations, as required.
  1. For each CornellAD group allowed access to your confidential data, create Auditing ACLs as shown, for both the Folder Structure and Files.
    The ITSO required minimum configuration is as follows:

    The ITSO required minimum configuration is shown:
