Create a Real-time Protection Policy for Isolation (Targeted RBI)
Policies are defined using a set of variables. These variables define the criteria for detecting policy violations.
For descriptions for each of the variables used, refer to Real-time Protection Policy Variables.
Note
When you see a text box during the policy workflow, click in the text box to view your additional options or to edit your selection(s). These options dynamically display based on your initial template choice. Many criteria are set to ‘Any’ by default. This means the policy engine will not match against the criteria.
When available, click Add Criteria to see what other match criteria are supported. Add more criteria to your policy to make it more specific.
Optionally, click the 'X' to the far right of the text box to remove a criteria.
To create a Targeted RBI Policy you need to take into account the following constraints and configurations for webpages to be isolated properly.
On the Real-time Protection Policies page, click New Policy > Web Access. Your menu options may differ based on the licenses available for your account
Important
Only Web Access is supported for targeted RBI.
Select the Source. Click in the text box to select users. Traffic Criteria is sorted as 'Source' and 'Destination.' The system will show the most appropriate criteria based on your policy template selection. Many criteria are set to 'Any' by default. This means the policy engine will not match against the criteria.
Optionally, click Add Criteria to see what other match criteria are supported. Add more criteria to your policy to make it more specific.
For Destination, Category is automatically selected and it’s the only criteria that can be used for targeted RBI. You can choose to isolate any web page which falls in the following category list:
Newly Registered Domain,
No Content,
Parked Domains,
Security Risk (and/or any Security Risk sub category),
Uncategorized
Web Proxies/Anonymizers.
These categories are described in the RBI Category Definitions.
You can add more Destination criteria. The system will show the most appropriate criteria based on Application, Category, App Instance, or Private App selection. Leave this blank for RBI policies.
Select a Profile and Action. For RBI policies, select the "Isolate" action.
Do not add a DLP profile. They do not apply for targeted RBI.
Enter a name and a description.
Important
When creating policy names, only use alphanumeric characters and symbols such as "_" underscore, "-" dash, and "[ or ]" square brackets. You cannot use the greater than ">" and less than "<" symbols in policy names.
Select an Email Notification. Select the notification frequency. Choose None if you don't want an email notification about the policy violation and the resulting action. When you choose 'Every,' you can select the frequency of the email notifications from the dropdown list – 30 Mins, 60 Mins, 6 Hours, 24 Hours. Or, choose to notify 'After each event.'
Select the User, Admin, or Users to be notified. You can use the default email template or create a new template. Optionally, you can specify an email address that will appear as the sender in the email notification. When finished, click Done to save your email notification setting and exit the window.
Click Save in the upper right corner to save your new policy. You should see it in the Policy list page.
Real-time Protection Policy Variables
The following variables can be defined for an Real-time Protection policy. You can use a variety of variables in a policy. If a variable is not used in the policy, it is defined as Any.
Variable | Description |
|---|---|
Users | Users created manually in the UI or Active directory users that are automatically populated from the enterprise AD server. |
User Groups | These are the Active Directory (AD) groups that are automatically populated to the Netskope cloud from the Enterprise AD server. Specifying user groups in a policy requires installing the Netskope AD adapter on a server that is part of your domain in order to export the AD user group names. |
Organizational Unit | This information is obtained from the exported AD groups. Specifying organizational units in a policy requires installing the Netskope AD adapter on a server that is part of your domain in order to export the AD organizational unit names. |
Cloud Apps + Web | Cloud app variables include:
|
Cloud Confidence Index Level (CCI Level) | A CCI Level can be applied when certain app categories, like Application Suite, are chosen. CCI measures the enterprise readiness of the cloud apps taking into consideration their security, auditability, and business continuity. Each app is assigned a score of 0-100, and based on the score, placed into one of five cloud confidence levels: Excellent, High, Medium, Low, or Poor. CCI can be used as a matching criteria in the policy. For example, you can choose to not let users share content in cloud storage apps rated Medium or below. |
DLP Profile | A data loss prevention (DLP) profile detects violations like PCI (which identifies credit card information). DLP profiles and rules can be configured in Policies > DLP. |
Threat Protection Profile | A threat protection profile detects malware files and malicious sites. Threat protection profiles can be configured in Settings > Threat Protection. |
Activities | The Netskope content analytics engine performs deep packet inspection to detect a specific cloud app and also to extract the relevant information about the activities performed with that app. It can detect if the user downloads a file, uploads a file, shares a file, and also detects the file name, and so on. Today the Netskope engine can detect 4000+ apps and can track 4500+ activities. |
Constraints | What the user is allowed to do for that specific activity (like allowed to share only within the organization). Constraints are shown only for the activities that support each constraint. Constraint profiles are defined in Policies > Profiles > Constraints. Refer to Profiles for details on configuring constraints profiles. |
Additional Attributes | These optional variables detect the following:

Action | Action taken when a violation is detected:
