Change Auditor 7.4 - User Guide


	TIP: Whenever you upgrade from a previous version of Change Auditor, the default configuration settings will be restored. Therefore, if you want to modify the default configuration settings, it is best to copy the default configuration and then save it using a different name. NOTE: The values for the proxy server settings are not included when you copy a configuration.

The default configuration consists of the following settings:

System Settings:

•

Polling Interval: 900 seconds

•

Forwarding Interval: 5 seconds

•

Kerberos Ticket Lifetime: 10 hours

A Kerberos user ticket can be used to verify your identity and gain access to specific resources or services in your domain. A golden ticket is a forged Kerberos ticket. An attack using a golden ticket is extremely dangerous due to the forged identity, elevated access it allows, and because it can be reused over its lifetime (10 years by default).

The setting determines the maximum ticket lifetime. When this value is exceeded, the “Kerberos user ticket that exceeds the maximum ticket lifetime detected” domain controller authentication event is generated which may indicate a possible golden ticket attack.

•

Retry Interval: 300 seconds

•

Maximum events per connection: 1,500

•

Agent Load Threshold: 10,000

•

Allowed time for connection: 24 x 7


	NOTE: These system settings apply to both server agents and workstation agents.

Proxy Server settings

•

Proxy Server: Not set

•

Port: 8080

•

Requires authentication: Not set

File System settings:

•

Discard duplicates that occur within: 10 seconds


	NOTE: This setting only applies to file system auditing which is available with Change Auditor for Windows File Servers, Change Auditor for EMC and Change Auditor for NetApp.

AD Query settings:

•

Discard query results less than: 0 records

•

Discard queries taking less than: 20 milliseconds

•

Discard duplicate queries occurring within: 15 minutes

•

AD Query auditing enabled


	NOTE: These settings only apply to Active Directory query auditing which is available with Change Auditor for Active Directory Queries.

Exchange settings:

•

Discard duplicate folder opens that occur within: 0 seconds


	NOTE: This setting only applies to Exchange auditing which is available with Change Auditor for Exchange.

You can define and assign different agent configurations to each deployed server agent from the Agent Configuration page on the Administration Tasks tab. However, workstation agents always use the default configuration; they cannot be assigned to a different agent configuration.

When the default configuration is modified, workstation agents will only receive these modifications when the polling interval determines there has been a change; clicking Refresh Configuration on the Agent Configuration page only pushes agent configuration changes out to server agents.

To enable custom auditing and protection, you must assign templates to an agent’s configuration. The custom auditing and protection features that require custom templates to be assigned to an agent’s configuration are:

•

Excluded Accounts Auditing

•

File System Auditing

•

File System Protection

•

Registry Auditing

•

Service Auditing

•

SQL Auditing


	NOTE: The NetApp, EMC, SharePoint, and Office 365 auditing templates define which agents are used to capture events; however, these templates do not use the agent configurations from the Agent Configuration page as described in this section. See the Quest Change Auditor for NetApp User Guide, Quest Change Auditor for EMC User Guide, Quest Change Auditor for SharePoint User Guide, Office 365 and Azure Active Directory Auditing User Guide.

Agent Configuration page

This page displays when Agent is selected from the Configuration task list in the navigation pane of the Administration Tasks tab. From here you can define and assign agent configurations.


	NOTE: Workstation agents always use the default configuration and cannot be assigned to a different agent configuration; therefore, they are not included on the Agent Configuration page.

The following information is available for each deployed server agent. To display columns not on by default, use the Field Chooser button located to the far left of the column headings.


	NOTE: All dates and times are based on the client’s current local date and time. The format used to display the date and time is determined by the local computer’s regional and language setting.

Define agent configurations

To define a new agent configuration:

From the Agent Configuration page, click Configurations.

The Configuration Setup dialog opens, which contains a list of configuration definitions available as well as the means for creating a new configuration.

Click Add to create a new definition or click Copy to duplicate the configuration selected in the Configurations list box.

This adds a new configuration to the list, allowing you to name the new configuration, specify the system settings and assign auditing and protection templates to the configuration.

With the new/copied configuration highlighted in the Configuration list, enter the name for your new agent configuration.

Use the tabbed pages at the top of the dialog to modify the system settings, file system settings, AD Query settings, Exchange settings, Defender auditing, and Authentication Services auditing. The settings that can be modified on these tabs include:

Table 2. Agent Configuration settings

To add an auditing or protection template to the selected configuration, use the Auditing and Protection Templates pane. This pane displays the auditing and protection templates previously defined.

Use one of the following methods to assign a template to an agent configuration:

•

Select a template and ‘drag and drop’ it onto a configuration in the Configuration list.

•

Select a configuration from the Configuration list and ‘drag and drop’ it onto a template in the Auditing and Protection Templates pane.

•

Select a configuration, then select a template, right-click and select Assign.

•

Select a configuration, then select a template, click in the corresponding Assigned cell and click Yes.

Repeat this step to add additional templates to the selected configuration.

If the templates list is empty or you want to define a new template, click Edit Templates.

•

On the Auditing and Protection Templates dialog, select the tab for the type of template to be added (e.g., Excluded Accounts) and click Add Template.

•

The associated wizard will be displayed allowing you to define the auditing or protection to be applied. Refer to the appropriate chapters in this guide for details on completing each of these wizards.

Once you have defined the new template, click OK to close this dialog and return to the Configuration Setup dialog. Select this new template, right-click and select Assign.

Once you have named the configuration, selected the system settings and added auditing or protection templates, click OK to save your configuration and return to the Agent Configuration page.
