NTFS Permissions Auditor - Online Manual

Filter Manager

The Filter Manager lets you create named filters that find specific permission patterns in your audit results. Filters are a Pro feature.

Instead of scrolling through thousands of permission entries, you can define criteria like “show only Full Control permissions for non-admin users” or “find all folders where Everyone has access” and apply them instantly.

Creating a Filter

  1. Open the Filter Manager from the report view toolbar
  2. Click to create a new filter — it starts with a default name “New filter” and one empty condition
  3. Give the filter a descriptive name
  4. Configure your filter conditions (see below)
  5. Click Save

Saved filters are stored in the database and available across all audit results. You can also assign a saved filter as the default for a profile (see Profile Options).

Filter Conditions

Each filter consists of one or more conditions. A condition has three parts:

Field — What to test. Available fields fall into three categories:

Account fields:

Field What it matches
Account Name The logon name (e.g., DOMAIN\jsmith)
SID The security identifier string
Account Type User, Group, Computer, etc.
Domain Name (NetBIOS) The short domain name
Domain Name (DNS) The full DNS domain name
Domain SID The domain’s security identifier
Group Has No Members Whether a group has zero members
SID Lookup Failed Whether the SID could not be resolved (orphaned)
Account Disabled Whether the account is disabled in AD
Manager The account’s manager field from AD
Department The department field from AD
Job Title The job title field from AD

Folder fields:

Field What it matches
Directory Owner The NTFS owner of the folder
Directory Has Full Permission To Whether a specific account has any permissions on the folder
Directory Inherits Permissions Whether the folder inherits from its parent
Permissions Match Parent Whether the folder’s permissions are identical to its parent

Permission fields:

Field What it matches
Permission Type (Allow/Deny) Whether the permission is an Allow or Deny entry
Basic Permission Full Control, Modify, Read & Execute, etc.
Advanced Permission Individual FileSystemRights flags
Applies To The scope (This folder only, This folder and subfolders, etc.)
Is Inherited Whether the permission is inherited from a parent folder

Operation — How to compare. Available operations depend on the field type:

Operation Works with
Is Equal / Not Equals Text and enum fields
Contains / Not Contains Text fields, permission lists
Starts With / Not Starts With Text fields
Ends With / Not Ends With Text fields
Is Empty / Not Empty Text fields

Value — What to compare against. For text fields, you type the value. For enum fields (like Account Type or Basic Permission), you select from a dropdown.

Combining Conditions with AND / OR

When a filter has multiple conditions, they are linked with AND or OR logic:

  • OR — The entry matches if any of the OR-linked conditions are true. OR conditions are grouped together.
  • AND — Creates a new group. The entry must match all AND-linked groups.

For example, to find “Full Control permissions for non-admin users”:

  1. Basic Permission Contains Full Control
  2. AND Account Name Not Contains admin

To find “Everyone OR Authenticated Users access”:

  1. Account Name Is Equal Everyone
  2. OR Account Name Is Equal Authenticated Users

You can build complex filters by combining AND and OR groups.

Applying and Clearing Filters

Apply a filter: Select a saved filter from the dropdown in the report view toolbar and click Apply. The results are filtered immediately — matching entries are shown in normal text, non-matching entries are greyed out.

Clear a filter: Click the Clear button to remove the active filter and show all results again.

Filters can be applied during the audit (via the profile’s default filter) or after the audit completes. When applied after, the original data is preserved — filters only change the display, not the underlying data.

If the Account View has been prepared when you apply or clear a filter, it is automatically re-prepared to reflect the new filter state.

Editing and Deleting Filters

To edit a saved filter, select it in the Filter Manager and modify the conditions. Click Save to update.

To delete a filter, select it and use the delete action. If the deleted filter was assigned as a profile’s default, the profile’s default filter is cleared.

Practical Filter Examples

Find all “Everyone” access:

  • Account Name Is Equal Everyone

Find orphaned SIDs (deleted accounts with permissions):

  • SID Lookup Failed Is Equal Yes

Find excessive permissions for regular users:

  • Basic Permission Contains Full Control
  • AND Account Type Is Equal User

Find folders with broken inheritance:

  • Directory Inherits Permissions Is Equal False

Find disabled accounts that still have access:

  • Account Disabled Is Equal True

Find all Deny entries:

  • Permission Type Is Equal Deny

Find permissions for a specific department:

  • Department Contains Finance
