Step 1: Copy
the SAML Configuration from Identity as a ServiceServiceNow provides a cloud computing platform to help companies manage digital workflows for enterprise operations (see https://www.servicenow.com). You can protect access to ServiceNow by integrating ServiceNow with Identity as a Service. Once integrated, users can use single sign-on to log in to their ServiceNow account through Identity as a Service.
Note: This integration was tested using Identity as a Service version 5.13 and ServiceNow Paris developer instance. Other versions of ServiceNow may require integration and configuration steps that differ from those documented in this procedure. For other versions of ServiceNow, this integration guide may be used as an initial approach for integrating ServiceNow. In the event of other issues, contact support@entrust.com for assistance.
Before you begin, you need to configure SAML 2.0 for ServiceNow. See https://saml-doc.okta.com/SAML_Docs/How-to-Configure-SAML-2.0-for-ServiceNow.html for more information.

11. Select Enable Strict Access for Application to set the resource rule to deny access regardless of the outcome from other resource rules. If this option is disabled for any resource rule that denies access, the user is allowed access if at least one resource rule allows access.
12. For each Advanced Risk Factor, click the Deny option to deny access to the application if the risk factor fails regardless of the results of the other risk factors.
13. Click Date/Time to set the conditions as follows:
a. Select one of the following:
– Allow Date/Time to set when a user can access the application.
– Deny Date/Time to set when the user cannot access the application.
The Date/Time Context Condition Settings appear.
b. Select the Condition Type:
– Specific Date Range Condition—Allows or denies access to the application during a select period of days.
– Time-of-day and/or Day of Week Recurring Conditions—Allows or denies access to the application on a specific time of day, day of the week, or both. Recurring times selected only apply to days not denied.
– Clear Selection—Clears existing Date and Time conditions.
c. Set the Condition Type settings, as follows:
i) Select Use local time zone to use the local time zone or deselect Use local time zone to use the local time zone and begin typing the time zone in the Begin Typing Timezone name field and select the time zone from the drop-down list.
ii) If you selected Specific Date Range Condition, click Start Date to select a start date from the pop-up calendar. Optionally, select the End Date.
iii) If you selected Time-of-Day and/or Day-of-Week, click Start Time and select the start time from the pop-up clock. Optionally set the End Time. You must also select the days of the week for the condition.

c. Select None to not restrict any IP addresses.
d. Click OK to return to the Authentication Conditions Settings.
16. Click Machine Authentication to set the Machine Authentication Condition Settings, as follows:
a. Set the Machine Authentication Risk is less than or equal to the value that the machine authenticator's total risk score must be less than during authentication to pass this condition.
The risk score is based on the attribute differences
between a user's Machine Authentication information and that recorded
on Identity as a Service before the condition fails. If an attribute does
not match, the attribute incurs the number of risk points shown in Non-Matching Risk Points for that attribute. The
Non-Matching Risk Points values of each non-matching
attribute are added together, resulting in a total risk score. This score
is normalized to be out of 100 as follows:
Total Risk Score = (Total Risk Points
of Failing Attributes / Maximum Risk Points of All Enabled Attributes)
* 100
The resource rule condition fails when the number of non-matching risk
points exceeds the Machine Authentication Risk value defined in this step.
A value of 0 means that a single attribute
difference causes the Device Fingerprint
condition to fail. The default value is 3.
The value between 0-50 can be entered.
The default value is defined by the Machine Risk Limit.
See Modify machine authenticator settings.
b. Click Save.
17. Define the Location History / Known Locations and Travel Velocity conditions. The Risk-Based Authentication (RBA) settings of your Identity as a Service account define the location history and travel velocity conditions. See Manage risk-based authentication settings for more information.
18. Set the Device Certificates risk factor to require the client to perform client-authenticated SSL with a certificate issued from a trusted CA to pass.
19. Set the risk score for application conditions to set the risk percentage a user receives if they fail to meet the condition, as follows:
● Click the dot next to the condition setting and slide the risk scale to the risk percentage
-or-
● Click the 0% and enter the risk points and then click OK.
The default setting is 0%. The Risk percentage determines the authentication requirements as set by the Authentication Decision. When a user attempts to authenticate to an application, the final risk percentage is the sum of all failed conditions.
20. Set the Authentication Decision risk level for Medium Risk and High Risk as follows:
a. Click the risk threshold percentage to the right of Medium Risk or High Risk. The Risk Threshold dialog box appears.
b. Enter the risk percentage.
c. Click OK.
21. Select the Authentication Flows for Low Risk, Medium Risk, and High Risk from the drop-down lists. The Authentication Flows flowchart updates based on your selections.
22. Click Submit to create the resource rule.
