Add Shared Policy/Edit Shared Policy dialogs
These dialogs allow you to add or edit a shared risk policy. They are accessed by either clicking the button to open the Add Shared Policy dialog, or selecting a previously created shared risk policy and clicking the button to open the Edit Shared Policy dialog.
Policy Name
Enter a unique name for the shared risk policy.

Select this check box to disable overrides for this risk policy. This setting applies to all applications that use the shared risk policy.
How does this work?
Click this link to open the Using the Policy Editor dialog which provides a brief overview of how to use the Policy Editor. Click Close to close the dialog.
Click this button to open the Select conditions to monitor dialog. Click OK to close the dialog.
Click this button to preview the risk policy. Once preview mode is active, select any of the check boxes to the left of a condition or modifier name to preview the risk score that would occur should the selected items be triggered during an access attempt. The Risk Score field displays the risk score that would occur if all of the selected conditions and modifiers were triggered.

Click this button to save the shared risk policy.
Close
Click this button to close the dialog. If changes were made to the shared risk policy, a warning will appear allowing you to select whether or not to save the changes before closing the dialog.
Alerting section - This section of the wizard allows you to configure alerting for the shared risk policy. Click Alerting to display the available settings.
IMPORTANT: When multiple, identical alerts for the same risk policy occur within a 5 minute period, the Security Analytics Engine will only send one alert. If alerting is used in risk policies with multiple conditions, you may want to assign different scores for each condition since there is a chance that a user may attempt access twice in that 5 minute window and trigger different conditions yet still cause the same score.
Notify Admin
Select the check box to begin sending email alerts and in the field enter the email address of the person that will be receiving the alerts.
Notify User
Select the check box to send an email alert to the user attempting access when they exceed a certain score.
If Notify User is selected, click this button to open the Customize User Alert Email dialog which is used for customizing the subject and descriptive body text of the alert email sent to the user. Once edits are made, click Accept to close the dialog.
Alert When
Select one of the following options:
•
Always - Send alerts when a risk policy is evaluated by the application and when the application updates user behavior data.
•
Only when specified - Sends an alert when the risk policy used for evaluation generates a risk score for the application.
Scores <nn> Or More
In this field enter the minimum risk score (1-100) a user must receive in order for an alert to be sent.
The following appear based on the selections made on the Select conditions to monitor dialog. For each category, a slider bar will appear for each of the conditions and moves from left to right to increase the condition score in increments of ten between 0%-100%. A condition set to 0% will not impact the risk score when triggered and a condition set to 100% will cause the highest possible risk score when triggered.

Introduction

Before an application can use the Security Analytics Engine to generate risk scores, an application definition must be added and configured within the Security Analytics Engine Administration web site using the Applications page. In addition to adding an application, you also need to configure the risk policies for that application to determine how the Security Analytics Engine evaluates the risk of allowing a user to access the application as well as any risk policies which will be used for alerting. Although client applications use only one risk policy at a time for evaluating access attempts, all risk policies associated with an application that are configured for alerting will also send alerts if they are triggered during an access attempt. For more information on the different uses for risk policies, see Risk policies.
From the Home page of the Security Analytics Engine Administration web site, click on the Applications link to open the Applications page where you can create and manage applications and risk policies.
