Configure Advanced Settings for Google Drive

This stage allows you to select notification channels if a policy violation occurs. The notification alerts are sent at two levels; admin and end-user. Admin users are the Nightfall administrators who generally work on the Nightfall SaaS application and configure various settings in Nightfall. End-users are owners or editors of the file in which the violation was detected.

Admin Alerting

This section allows you to send notifications to Nightfall users.

The steps to configure alert channels for policy-level integration are the same as in the case of integration-level alerts. You can refer to this document for steps.

Automated Actions

This section describes the various actions that Nightfall takes automatically when a violation is detected. You must turn on the toggle switch to enable an action. All the automated actions are permanent and cannot be reversed once applied. You can also set the timeline as to when an action must be taken (immediately after detecting a violation or after some time).

The various automated actions are described as follows.

• Remove all external users and groups: This action revokes the file access in which sensitive data was found. All external users and groups will no longer have access to the file. You must also select the timeline as to when this action must be taken after a policy violation is detected. You can either choose to take the action immediately after detecting a violation or after a few minutes, hours, or days.

• Remove all internal users and groups: This action revokes the file access in which sensitive data was found. All internal users and groups will no longer have access to the file.

• Restricted: This action restricts the file access only to those users who have the link to access it.

• Disable Download, Print, and Copy: This action disables downloading, printing, or copying the file in which sensitive data was found.

• Apply Labels: This action allows you to automatically apply labels on files with sensitive data. You can choose to apply either a badged label or standard labels. All the Labels are listed under the Add Label drop-down menu. You must click this drop-down menu and select the required label(s).

The Apply action immediately or after some time option is not applicable to the Apply Labels action.

End-User Notification

This section allows you to configure notifications to be sent to the end user whose actions triggered the violation.

Custom Message

Enter a custom message to be sent to the end user. This message is sent in an Email. You can modify the default message provided by Nightfall and draft your message. The total character length allowed is 1000 characters. You can also add hyperlinks in the custom message. The syntax is <link | text >. For example, to hyperlink https://www.nightfall.ai with the text Nightfall website, you must write <https://www.nightfall.ai | Nightfall website> .

Automation

You can select one of the following methods. You must turn the toggle switch to use this option.

• Via Slack: This option sends a Slack notification to the user whose actions triggered the violation.

• Via Email: This option sends an Email to the user whose actions triggered the violation.

End-User Remediation

End-user remediation (also known as Human Firewall) allows you to configure remediation measures that end users can take, when a violation is detected on their Google Drive files. You must turn on the toggle switch to use this option. When an end-user action triggers a violation, they receive an email with content mentioned in the Custom Message section. Apart from the Email content, end users can also view one or multiple actions described below. All the actions that a Nightfall admin enables here, are visible to end-users in the Email.

• Remove External User(s): This action revokes the file access permissions. All external users lose access to the file in which sensitive data was found. If you have enabled the Remove all external users and groups action in the Automated Actions section, this action is disabled.

• Restricted Link: This action resets the file access permission to only those users who have the link to the file. If you have enabled the Restricted action in the Automated Actions section, this action is disabled.

• Disable Download: This action disables the download of the file in which sensitive data was found. If you have enabled the Disable Download, Print, and Copy action in the Automated Actions section, this action is disabled.

• Apply Labels: This action allows end-users to apply either badged label or standard labels on the files with sensitive data. End-users can apply a single badge label and up to four standard labels. If you have enabled the Apply Labels action in the Automated Actions section, this action is disabled.

• Report as False Positive with Business Justification: This option allows end users to report false positive alerts and provide a business justification as to why the alert is considered to be false positive.

• Report as False Positive: This option allows end users to report false positive alerts.

When a Violation is Reported as False Positive: You can use this option to set actions to be taken when a violation is reported as false positive by the end-user. You can either set the remediation to be automatic or manual.

Remind Every (until Violation expires): You can use this option to set a reminder for the end-user to take action on the violation. You can choose to remind the end user every 24, 48, or 72 hours.
