Policies allow you to define the way you want your users to behave in the cloud. They enable you to detect risky behavior, violations or suspicious data points and activities in your cloud environment, and if required, to integrate remediation work flows to achieve complete risk mitigation. There are multiple types of policies that correlate to the different types of information you want to gather about your cloud environment and the types of remediation actions you may want to take.
For example, if there is a data violation threat that you want to quarantine, you will need a different type of policy in place than if you want to block a risky cloud app from being used by your organization.
When you look at the Policy page, the various policies and templates can be distinguished by type and icon to see which policies will be available. The available policies depend on the data source and what you have enabled in Cloud App Security for your organization, for example, if you uploaded Cloud Discovery logs, the policies relating to Cloud Discovery will be displayed.
The following types of policies can be created:
|Policy type icon||Policy type||Use|
|Activity policy||Activity policies allow you to enforce a wide range of automated processes leveraging the app provider’s APIs. These policies enable you to monitor specific activities carried out by various users, or follow unexpectedly high rates of a certain type of activity.|
|Anomaly detection policy||Anomaly detection policies enable you to look for unusual activities on your cloud based on the risk factors you set here to alert you when something happens that is different from either the baseline of your organization or from the user's regular activity.|
|App discovery policy||App discovery policies enable you to set alerts that notify you when new apps are detected within your organization.|
|Cloud Discovery anomaly detection policy||Cloud Discovery anomaly detection policies look at the logs you use for discovering cloud apps and search for unusual occurrences. For example, when a user who never used Dropbox before suddenly uploads 600 GB to Dropbox, or when there are a lot more transactions than usual on a particular app.|
|File policy||File policies enable you to scan your cloud apps for specified files or file types (shared, shared with external domains), data (proprietary information, PII, credit card information, etc.) and apply governance actions to the files (governance actions are cloud-app specific).|
Cloud App Security helps you mitigate different risks in the cloud. You can configure any policy and alert to be associated with one of the following risks:
Access control: Who accesses what from where?
Continuously monitor behavior and detect anomalous activities, including high-risk insider and external attacks, and apply a policy to alert, block, or require identity verification for any app or specific action within an app. Enables on-premises and mobile access control policies based on user, device, and geography with coarse blocking and granular view, edit, and block. Detect suspicious login events, including multi-factor authentication failures, disabled account login failures, and impersonation events.
Compliance: Are your compliance requirements breached?
Catalog and identify sensitive or regulated data, including sharing permissions for each file, stored in file-sync services to ensure compliance with regulations such as PCI, SOX, and HIPAA
Configuration control: Are unauthorized changes being made to your configuration?
Monitor configuration changes including remote configuration manipulation.
Cloud Discovery: Are new apps being used in your organization? Do you have a problem of Shadow IT apps being used that you don't know about?
Rate overall risk for each cloud app based on regulatory and industry certifications and
best practices, enables you to monitor the number of users, activities, traffic volume and typical usage hours for
each cloud application.
DLP: Are proprietary files being shared publicly? Do you need to quarantine files?
On-premises DLP integration provides integration and closed-loop remediation with existing on-premises DLP solutions.
Privileged accounts: Do you need to monitor admin accounts?
Real-time activity monitoring and reporting of privileged users and admins.
Sharing control: How is data being shared in your cloud environment?
Inspect the content of files and content in the cloud, and enforce internal and external sharing policies. Monitor collaboration and enforce sharing policies, such as blocking files from being shared outside your organization.
Threat detection: Are there suspicious activities threatening your cloud environment?
Receive real-time notifications for any policy violation or activity threshold via text message or email. By applying machine learning algorithms Cloud App Security enables you to detect behavior that could indicate that a user is misusing data.
How to control risk
Follow this process to control risk with policies:
Create a policy from a template or a query.
Fine-tune the policy to achieve expected results.
Add automated actions to respond and remediate risks automatically.
Create a policy
You can either use Cloud App Security’s policy templates as a basis for all your policies, or create policies from a query.
Policy templates will help you set the correct filters and configurations necessary to detect specific events of interest within your environment. The templates include policies of all types, and can apply to various services.
To create a policy from a policy templates, perform the following:
In the console, click on Control followed by Templates.
Click the + at the far right of the row of the template you want to use. A create policy page opens, containing the pre-defined configuration of the template.
Modify the template as needed for your custom policy. Every property and field of this new template-based policy can be modified according to your needs.
When using the policy filters, Contains will search only for full words – separated by comas, dots, spaces or underscores. For example if you search for malware or virus, it will find virus_malware_file.exe but it will not find malwarevirusfile.exe. If you search for malware.exe then you will find ALL files with either malware or exe in their filename, whereas if you search for “malware.exe” (with the quotation marks) you will find only files that contain exactly “malware.exe”. Equals will search only for the complete string, for example if you search for malware.exe it will find malware.exe but not malware.exe.txt.
- After you create the new template-based policy, a link to the new policy appears in the Linked policies column in the policy template table next to the template from which the policy was created.
You can create as many policies as you want from each template and they will all be linked to the original template, allowing you to track all policies built using the same template.
Alternatively, you can create a policy during investigation. If you are investigating the Activity log, Files or Accounts, and you drill down to search for something specific, at any time you can create a new policy based on the results of your investigation.
For example, if you are looking at the Activity log, and see an admin activity from outside the your office’s IP addresses.
To create a policy based on investigation results, perform the following:
In the console, click on Investigate followed by Activity log, Files or Accounts.
Use the filters at the top of the page to limit the search results to the suspicious area, for example, in the Activity log page, click Activity and select Admin logon. Then, under IP address, select Category and set the value to not include IP address categories you've created for your recognized domains, such as your admin, corporate and VPN IP addresses.
In the upper right corner of the console, click New policy from search
A create policy page opens, containing the filters you used in your investigation.
Modify the template as needed for your custom policy. Every property and field of this new investigation-based policy can be modified according to your needs.
When using the policy filters, Contains will search only for full words – separated by comas, dots, spaces or underscores. For example if you search for malware or virus, it will find virus_malware_file.exe but it will not find malwarevirusfile.exe.
Equals will search only for the complete string, for example if you search for malware.exe it will find malware.exe but not malware.exe.txt.
For more information on setting the policy fields, refer to the corresponding policy documentation:
Add automated actions to respond and remediate risks automatically
For a list of available governance actions per app, see the Governing connected apps.
You can also set the policy to send you an alert by email or text message when matches are detected.
To set your notification preferences, got to Customize the portal
The maximum number of alerts that will be sent via text message is 10 per phone number per day. Note that the day is calculated according to the UTC timezone.
Enable and disable policies
After you create a policy, you can enable or disable it. This avoids the need to delete a policy after you create it in order to stop it. Instead, if for some reason you want to stop the policy, simply disable it until you choose to enable it again.
- To enable a policy, in the Policy page, click the three dots at the end of the row of the policy you want to enable, and select Enable.
- To disable a policy, in the Policy page, click the three dots at the end of the row of the policy you want to disable, and select Disable.
By default, after you create a new policy, it is enabled.
