The next step is to assign login authentication profiles to policies. In this task, you set up a policy so that if specified conditions are met, the affected users proceed according to a specified authentication profile. If those conditions aren't met, you can specify a default authentication profile or block access entirely.
For example, you could set a policy that says that during work hours of Monday to Friday, 8:00 am to 5:00pm, users log in using an authentication profile that requires a password and a security question. For users logging in outside of those days or times, users will have to login with a password, security question, and an email confirmation code.
As a reminder, you use authentication profiles to define the necessary authentication methods to use. You define authentication rules to specify where to enforce those authentication profiles inside of a policy set.
To assign a login authentication profile to a policy set:
- In the Admin Portal, go to Access > Policies and either click Add Policy Set to create a new policy or click an existing policy to edit.
Create or edit the policy set and assign it to the desired users or resources.
For details, see Creating policy sets and policy assignments.
In the Policy Settings area, navigate to Authentication > Centrify Server Suite Agents > and click one of the following settings:
Policy Setting Description Linux, UNIX and Windows Servers
For Linux and UNIX Servers or Workstations where the Centrify Agent for *NIX is installed and enabled.
For Windows Servers where the Centrify Agent for Windows is installed and enabled
For Centrify-managed workstations where the Centrify Agent for Windows is installed and enabled.
The operating system variant determines if it's a workstation.
For systems where either the Centrify Agent for *NIX or Centrify Agent for Windows is installed and enabled.
Note: For any of the above policy settings, the role assignment associated with this policy must include computer objects or groups in Active Directory and also the "Computer Login and Privilege Elevation" administrative rights.
Select Yes in the Enable authentication policy controls drop-down.
The Authentication Rules section displays. You use this section to define which authentication profiles apply under which conditions.
(Optional) If you want to specify conditions for which different authentication rules apply, click Add Rule. Otherwise, proceed to step
The Authentication Rules window displays.
Click Add Filter, and then click the same drop-down to spicy which kind of condition.
For example, you can create a rule that requires a specific authentication method when users access Privileged Access Service from an IP address that is outside of your corporate IP range. Supported filters are:
The authentication factor applies as follows:
For Privileged Access Service on-premise, the authentication factor is the connector's IP address when you log in. When using HTTP proxy, the authentication factor is the HTTP Proxy server’s IP address when you log in.
For Privileged Access Service from the Centrify user portal, the authentication factor is the tenant connectors’ public IP address when you log in. When using HTTP proxy, the authentication factor is the HTTP proxy server’s public IP address when you log in.
This option requires that you have configured the IP address range under Settings > Network > Corporate IP Range.
Note: For Windows machines that can access the Internet, the authentication factor is the machine's IP address when you log in.
The authentication factor is the cookie that is embedded in the current browser by the directory service after the user has successfully logged in.
Day of Week
The authentication factor is the specific days of the week (Sunday through Saturday) when the user logs in.
The authentication factor is a date before or after which the user logs in that triggers the specified authentication requirement.
The authentication factor is a specific date range.
The authentication factor is a specific time range in hours and minutes.
Risk Level: The authentication factor is the risk level of the user logging on to Admin Portal. For example, a user attempting to log in to Privileged Access Service from an unfamiliar location can be prompted to enter a password and text message (SMS) confirmation code because the external firewall condition correlates with a medium risk level. This Risk Level filter, requires additional licenses. If you do not see this filter, contact Centrify support. The supported risk level are:
- Non Detected — No abnormal activities are detected.
- Low — Some aspects of the requested identity activity are abnormal. Remediation action or simple warning notification can be raised depending on the policy setup.
- Medium — Many aspects of the requested identity activity are abnormal. Remediation action or simple warning notification can be raised depending on the policy setup.
- High — Strong indicators that the requested identity activity is anomaly and the user's identity has been compromised. Immediate remediation action, such as MFA, should be enforced.
- Unknown — Not enough user behavior activities (frequency of system use by the user and length of time user has been in the system) have been collected.
For the Day/Date/Time related conditions, you can choose between the user’s local time and Universal Time Coordinated (UTC) time.
- Click the Add button associated with the filter and condition.
Select the authentication profile you want applied if all filters/conditions are met in the Authentication Profile drop-down.
The authentication profile defines which authentication methods to use. If you have not created the necessary authentication profile, select the Add New Profile option in the list (it's at the bottom of the list).
- Click OK to close the Authentication Rules dialog box.
- If desired, continue adding authentication rules. You can drag the rules to change the order of priority. The highest priority rule is at the top of the list.
Select a default profile to be applied if a user does not match any of the configured conditions in the Default Profile (used if no conditions matched) drop-down.
Note: If you have no authentication rules configured and you select Not Allowed in the Default Profile dropdown, users will not be able to log in to the service.
If this policy setting is for Linux, UNIX, and Windows Servers, you have the option to configure how the pass-through duration applies. The pass-through duration is how long before the user needs to re-authenticate, and you define the pass-through duration in the authentication profile (for example, the default is 30 minutes). Select one of the following options:
- Never (default): Always prompt for MFA and ignore the pass-through setting.
- If Same Source and Target: Apply the pass-through duration if the user is logging in from the same system and where they're logging in to is the same system as compared to the initial login.
- If Same Source: Apply the pass-through duration if the user is logging in from the same system as compared to the initial login.
- If Same Target: Apply the pass-through duration if the user is logging in to is the same system as compared to the initial login.
- If desired, you can add multiple policy settings to the same policy set.
- Click Save.
