Microsoft Cloud App Security overview

Policies can be set to provide continuous compliance scans, legal eDiscovery tasks, DLP for sensitive content shared publicly, and many more use cases. Cloud App Security can monitor any file type based on more than 20 metadata filters for example, access level, file type. Context filters including user roles, file metadata, sharing level, organizational group integration, collaboration context, and additional customizable attributes.

Automated actions for governance and remediation. For more information, see Control. Only one governance action can be applied per file; hence, where there are multiple file policy matches for a file, the governance action of the first triggered policy will be applied.

File policies

For example, if a file policy has already applied an AIP label to a file, a second file policy cannot move the file to admin quarantine. Once enabled, the policy continuously scans your cloud environment and identifies files that match the content and context filters, and apply the requested automated actions.

These policies detect and remediate any violations for at-rest information or when new content is created.

Policies can be monitored using real-time alerts or using console-generated reports. Publicly shared files - Receive an alert about any file in your cloud that is publicly shared by selecting all files whose sharing level is public. Select files with a filename containing the name of your organization and which are publicly shared. Sharing with external domains - Receive an alert about any file shared with accounts owned by specific external domains.

Select the external domain with which you want to limit sharing.

Supported file types

Quarantine shared files not modified during the last period - Receive an alert about shared files that no one modified recently, to quarantine them or choose to turn on an automated action.

Sharing with unauthorized users - Receive an alert about files shared with unauthorized group of users in your organization. Select the users for whom sharing is unauthorized. Sensitive file extension - Receive an alert about files with specific extensions that are potentially highly exposed. Select the specific extension for example, crt for certificates or filename and exclude those files with private sharing level.

Give your policy a name and description, if you want you can base it on a template, for more information on policy templates, see Control cloud apps with policies.

Give your policy a Policy severity. If you have set Cloud App Security to send you notifications on policy matches for a specific policy severity level, this level is used to determine whether the policy's matches trigger a notification. Within Category , link the policy to the most appropriate risk type.

This field is informative only and helps you search for specific policies and alerts later, based on risk type. The risk may already be preselected according to the category for which you chose to create the policy. By default, File policies are set to DLP.

Create a filter for the files this policy will act on to set which discovered apps trigger this policy. Narrow down the policy filters until you reach an accurate set of files you wish to act upon.

Be as restrictive as possible to avoid false positives. When using the policy filters, Contains searches only for full words — separated by comas, dots, spaces, or underscores.

You're redirected to sign in the cloud app, and then add the relevant folders.

Under the second Apply to filter, select either all file owners , file owners from selected user groups or all file owners excluding selected groups. Then select the relevant user groups to determine which users and groups should be included in the policy. Select the Content inspection method. We recommend using Data Classification Services. Once content inspection is enabled, you can choose to use preset expressions or to search for other customized expressions.

In addition, you can specify a regular expression to exclude a file from the results. This option is highly useful if you have an inner classification keyword standard that you want to exclude from the policy. You can decide set the minimum number of content violations that you want to match before the file is considered a violation.

For example, you can choose 10 if you want to be alerted on files with at least 10 credit card numbers found within its content. When content is matched against the selected expression, the violation text is replaced with "X" characters. By default, violations are masked and shown in their context displaying characters before and after the violation.

You can select the option to Unmask the last four characters of a violation to unmask the last four characters of the violation itself.

By default it searches the content and the metadata. Choose the Governance actions you want Cloud App Security to take when a match is detected. You can always edit a policy, calibrate its filters, or change the automated actions. The policy is automatically enabled upon creation and starts scanning your cloud files immediately.

Take extra care when you set governance actions, they could lead to irreversible loss of access permissions to your files. It's recommended to narrow down the filters to exactly represent the files that you wish to act upon, using multiple search fields.

The narrower the filters, the better.
