This document explains the steps to install the Nightfall for Google Drive.
To install the Nightfall DLP for Google Drive integration, you must have the following:
A Google Workspace account, preferably a service account.
An admin user account of your organization's Google Workspace account (or any other Google Workspace account) on which you wish to install the integration.
To install Nightfall for Google Drive:
Log in to Nightfall.
Click Google Drive under the MY INTEGRATIONS section (click Show more if you are unable to view Google Drive)
Click Begin Setup.
The access permission page is displayed as follows. Copy the client ID and Scopes ID generated.
Login to your Google Workspace with an admin account.
Click the menu icon.
Select Admin.
In the Admin console left pane, expand Security and then expand Access and data control.
Click API controls.
Click MANAGE DOMAIN WIDE DELEGATION under Domain wide delegation.
Click Add New.
Paste the Client ID copied from the Nightfall app, in the Client ID field.
Paste the Scopes ID copied from the Nightfall app, under OAuth Scope field. Use comma to add multiple scope IDs.
Click AUTHORIZE.
Return to the Nightfall app and click Next Step.
Click Connect.
Once the installation is completed, you can view the details of your Google Drive in the Nightfall app.
Once the installation is completed, Nightfall connects to your Google Workspace account and fetches all the domains. In the above image, you can see that 3 domains are fetched. These three domains were already present in your Google Workspace and are considered to be internal. You can add additional domains by clicking the ellipsis menu at the right end and selecting Manage Domains.
The trigger section further enhances the unwanted noise reduction capabilities. With the trigger section, you can
Set what download behavior can be termed as an exfiltration event.
Exclude downloads by trusted apps from being termed as exfiltration events.
In the trigger section, you can set the download behavior, the download frequency to be precise, must be termed as an exfiltration event.
To configure the Trigger section:
Set the minimum number of downloads threshold that must be considered as an exfiltration event.
Set the required time period (frequency). If the minimum download threshold (set in the previous step) is reached or exceeded, within the set time period, an exfiltration event is generated.
In the following image, the configurations are set such that if an asset is downloaded 2 or more times within 10 minutes, an exfiltration event is triggered.
You must set the action frequency carefully. For example, consider that you set the download condition as 5 or more files, within 1 hour. In this case, if a user downloads four assets, every 1 hour, the policy does not trigger a violation, since the condition is not met.
Depending on your environment, a significant number of downloads may be attributed to applications (i.e. backup apps). You may choose to ignore such download events to reduce the noise and focus your monitoring on unexpected application and user download events.
The Exclude apps section allows you to exclude specific applications from being monitored by your policy.
To configure the Exclude apps section, select the applications to exclude from the drop-down menu. Once saved, Nightfall will not alert on download events attributed to the excluded applications.
Exfiltration policies allow you to monitor download events across your Google Drive environment. Through real-time download monitoring, you can identify insider risk and anomalous behaviour before it escalates to large scale security incidents. You can monitor download activity for specific users or user groups, specific drives containing valuable sensitive assets, or downloads of any files containing sensitive data types as discovered and classified by Nightfall's ML/AI based detectors.
You can set up your policies to monitor only, to educate users in real-time about your download and data governance policies, or to automatically suspend user access to the Google Workspace to enforce zero tolerance policies.
The detailed steps to configure the Google Drive Exfiltration policy is explained in the following documents.
Data exfiltration, also known as data theft, data exportation, or data extrusion, is the unauthorized transfer of data from a device or network. It can occur as part of an automated attack or can be performed manually. The illegitimate transfer of data often looks very similar to legitimate transfers, making it difficult to detect.
Data exfiltration can occur in various ways and through multiple attack methods. Here are some of the most commonly used techniques:
Social Engineering and Phishing Attacks: These attacks trick victims into downloading malware and giving up their account credentials.
Outbound Emails: Cyber criminals employees or intruders use email to exfiltrate any data that sits on organizations’ outbound email systems.
Downloads to Insecure Devices: Data is transferred by users from secure, trusted systems to an insecure device. From there, the attacker can infiltrate the device and exfiltrate the data.
Uploads to Cloud Storage: Data can be exfiltrated from cloud storage when data is uploaded to insecure or misconfigured resources.
Nightfall provides a highly revolutionised solution to data exfiltration. Nightfall AI's exfiltration prevention capabilities easily integrate with existing tools, thus catering to security teams and companies across industries. Nightfall's exfiltration solution is much more than just a tool; it proactively protects against data breaches, providing tangible benefits for organizations striving to secure their sensitive information.

If you have not enabled any notification channels in the Admin alerting section, Nightfall admins are not notified.
If you have enabled the email notification in the Admin alerts section, Nightfall admins receive an email. The email is as shown in the following image.
The Email consists of the following data.
Event: The event that caused the violation. For Google Drive, the event is always a download of assets.
Actor: The Email ID of the user who downloaded the file.
When: The date and time when the email was downloaded.
Where: The name of the file that was downloaded.
Policies Violated: The name of the policy that was violated.
Violation Dashboard: The link to the Events screen to view the violation in detail.
Actions: The list of actions that the Nightfall admin can take.
Also, a Slack message is sent if you have enabled the Slack alerts for the Nightfall admin. The Slack message looks as shown in the following image.
If you have configured the Email notification for end-users and enabled the end-user remediation, end-users can take remediation actions from the Email itself. The end-user Email is shown in the following image.
If you have configured Slack notifications for end-user and enabled end-user remediation, end-users can view the Slack message as follows.
Nightfall admins can manage violations from within the Nightfall console. The Events page in Nightfall lists all the violations under the Exfiltration tab. End-users can get a detailed view of each exfiltration Event triggered.

You can click an event to view the details. The detail view window is as follows.
The detail view window consists of the following tabs.
Summary: The Summary tab displays highlights of the event like the name of the downloaded asset, the name of the violated policy, the email ID of the user who violated the policy, and so on.
Asset: The asset window displays the details of the asset and the history of the asset. You can also choose to view historic asset data. If there are multiple assets in a single violation, you can choose which asset's details must be displayed.
Actor: The actor tab displays the details and history of the user who downloaded the asset. You can choose to view historical data of the user. You can also add which can serve as metadata for the violation.
The events list view displays an ellipsis menu at the extreme right corner. Admins can click this menu to take appropriate action on an exfiltration event.
The various available actions are explained as follows.
Acknowledge: This action can be taken when you just wish to acknowledge that you have viewed the violation.
Notify Email: This action sends an email notification to the end-user who caused the violation.
Notify Slack: This action sends a Slack notification to the end-user who caused the violation.
Suspend Account: This action suspends the account of the user who caused the violation.
Ignore: This action ignored the violation. You can take this action when an event is false positive.
Copy Link: This action is only available on the Asset detail view. You can copy the direct link to the Event with this action.
Once the action is implemented, the status of the event changes respectively. By default, an event can have one of the following two statuses.
Active: The event has been generated but no action has been taken.
Input Requested: A notification has been sent to the end-user requesting their response.
You can also take action from the event detail view page. The actions are available at the bottom of the detail view page.
End-users receive notifications and remediation actions if the Nightfall admin has enabled these settings. The notifications are based on the settings configured in the section. The end-user remediation actions are based on the settings configured in the section.

The Exfiltration policies for MAC allow you to monitor if there are any uploads via browser or cloud storage apps. You can configure the domains in Internet that needs to be monitored and also the cloud storage apps which need to be monitored.
When there are any uploads to the configured domain or cloud storage apps, the Nightfall AI agent notifies this action. You can configure the notification channels through which you wish to receive notifications when there is an attempt to upload files/folders.
Once you have completed the installation of Nightfall agent, you must ensure that the connection is live. If the Nightfall agent cannot connect to the macOS device for more than 6 hours, the connection is closed. When the connection is live, a Connected message is displayed. If the connection is lost, Disconnected message is displayed.
Collections help you refine you monitoring to reduce noise from sanctioned upload destinations as well as closely monitor exfiltration of files originating from high value SaaS applications accessed through the browser. You can also define specific domain collections to closely monitor upload activity to specific categories of upload destinations. For instance, to track files uploaded to social media, you can create a domain collection called social media and add domains like Facebook, Instagram, Twitter, and so on. Similarly, you create a collection for known and sanctioned upload destinations that are safe to upload to so you can ignore from your monitoring policies or monitor upload of items originating from such domains. While creating a policy, you can directly add the collection to be monitored. All the domains in the collection will be monitored.
You can create a domain by either manually entering all the domain URLs manually or by uploading a comma delimited list of domains in a text file.

Nightfall Exfiltration for Salesforce helps you to keep tab of the exfiltration activities in your Salesforce orgs. Nightfall leverages Salesforce Shield Real Time Event Monitoring for exfiltration activities across your Salesforce orgs and identifies activities which are in violation to configured policies.
Download of attachments, files, reports and bulk download of objects are all exfiltration event recognised by Nightfall. You can configure policies to set appropriate thresholds for such events and identify them as unwarranted that may require scrutiny. You may configure the policy to alert the stakeholders who need to be notified and choose one of the available actions to be invoked automatically. You may also choose not to configure automated actions but only act after evaluating the specific exfiltration events.
Nightfall exfiltration leverages Salesforce Shield's Event Monitoring to identify exfiltration events. Salesforce Shield provides multiple security tools to safeguard your Salesforce orgs. Nightfall depends on Event Monitoring in Salesforce Shield which is available as an independent module within Salesforce Shield. You must enable the following Event Monitoring settings for all the Salesforce orgs that you wish to monitor,
Generate event log files - Generate an event log file when events occur in your org.
Enable Lightning Logger Events - Enable collection of Lightning Logger Events in custom components.
Enable the following events for storage and streaming
Bulk API Result Event - Track when a user downloads the results of a Bulk API request
File Event - Track file activity. For example, track when a user downloads or previews a file
Report Event - Track when a user accesses or exports data with reports
SessionHijacking Event - Track when an unauthorised user gains ownership of a Salesforce user’s session with a stolen session identifier
You can learn more about Salesforce Shield here and once enabled, advance to the next steps with Installing Nightfall DLP for Salesforce
If you have already onboarded your Salesforce org to Nightfall platform, please ensure you have the latest Nightfall DLP package deployed in your Salesforce org. Follow the steps mentioned in Upgrading Nightfall DLP to upgrade it to the latest version.
You must perform the above actions only on those Salesforce orgs in which the Salesforce Shield Event monitoring module is enabled.
The installation procedure remains the same as in case of Salesforce DLP for sensitive data. The links to the installation and upgradation documents are as follows.
In this stage, you select the Integration for which the policy is created. In this case, Google Drive integration must be selected.
Click Policies from the left menu.
Click + New Policy.
Select Exfiltration.
Select macOS.
When there is a high volume of exfiltration (basically download) in your organization, the scoping capability enables you to reduce the noise from low risk events so that you can zero in on genuine exfiltration events and resolve them.
Exfiltration (Download monitoring) can be scoped to:
Location: All or a specific set of drives
This allows you create flexible policies to monitor all or specific high-risk locations. This is a required scope for all policies.
User or User Group (Actor): Any or a specific set of users or user groups
This allows you to create custom policies for specific high-risk individuals or user groups. As such, you can create policies to monitor download activity by a disgruntled employee or departing employees. This can be set in combination to other scoping capabilities.
Permissions: Public, Organization or Restricted
This allows you to tailor your policies to drives or files with specific access restrictions. This can be set in combination to other scoping capabilities.
Detection rules: Any or a specific set of sensitive data protection detection rules
You can reuse any of detection rules you've already created or create new ones. This helps focus your detection on files which have associated sensitive data violations identified by your sensitive data scanning product. This can be set in combination to other scoping capabilities.
The Scope stage consists of two main sections.
Drive Selection: This section allows you to include various files and drives for monitoring. In this section, you can select the different types of drives to be monitored.
Add Filters: This section allows you to scrutinize your policy scope at more granular levels. While the Drive selection section allows you to select the whole drive to be monitored, this section provides you more granular level filters. You can select specific files within the selected drives for monitoring.
The Drive Selection section allows you to select various drives for monitoring. You can select either User Drives or Shared Drives to be monitored by Nightfall for exfiltration.
This section allows you to select various drives in your Google Drive to be monitored. There are two options in this section. You can either choose to scan the User drives, Shared drives, or both.
User Drives: The User Drives is the personal drive of the user. The files in this drive are visible only to the owner of the file and other users to whom the owner has granted access. User Drive is commonly known as My Drive in Google Drive. To monitor a User Drive, you must select the User drives check box as shown in the following image.
IMPORTANT
If you choose to monitor the User drives, all the User drives in your Google domain are selected for monitoring. You do not have the option to choose specific User drives for monitoring.
Shared Drives: Shared drives are common storage locations accessed by all the users in your Workspace. To select this option, you must select the Shared drives check box.
IMPORTANT
If you choose to monitor the Shared Drives, you can select whether to monitor all the Shared drives or only specific shared drives. Nightfall provides the following options.
If you select the All Drives option, all the Shared drives in your Google Workspace are selected for monitoring.
If you select the All Drives, except for option, you can exclude some shared drives from being monitored.
If you select the Specific Shared Drives option, you get the option to choose specific Shared drives for monitoring.
The following image displays the scenarios when you select the Shared Drives check box.
If you select the All Drives, except for option, you must also select the shared drives which must be excluded from monitoring.
Similarly, if you select the Specific Drive(s) option, you must also select the specific shared drives which must be monitored.
The filters section provides you the flexibility to include and exclude users at a granular level.
For instance, in the previous section, irrespective of whether you selected Shared Drive, User Drive, or specific User Drives, you ended up selecting one or a set of Drives for monitoring.
Once you select the Drives to monitor, in this section, you can overlay additional filters to further scope your monitoring. Nightfall provides the following additional filters:
Monitor specific: Choose this option to monitor one or a specific set of internal users. Once you choose this option, Nightfall populates the list of users from the synced IdPs in Directory Sync. You must select the required users.
Monitor all, except: Choose this option to exclude specific individuals from your monitoring policy. Once you choose this option, Nightfall populates the list of users from the synced IdPs in Directory Sync. You must select the required users.
If you have not configured the Directory Sync feature, the users list is populated from the Google Drive integration setup. As a result, you can see the Google Drive icon before the user name. However, if you have set up Directory sync, the users list is fetched from the IdP used for the configuration. In the above image, the users list is populated from the Microsoft Azure IdP and hence you can see the Azure icon before the users’ names.
Important
For exclusions, Nightfall only checks the file ownership. For inclusions, Nightfall checks both file ownership and shared access. This rule is applicable to all the filters.
Monitor Specific: Choose this option to monitor one or a specific set of external users. Once you choose this option, you must manually enter the email ID(s) of the external users and hit the enter key.
Monitor all, except: Choose this option to exclude specific external users, from being monitored. Once you choose this option, you must manually enter the email ID(s) of the external users and hit the enter key.
Monitor specific: Choose this option to monitor one specific or a set of internal groups. Once you choose this option, Nightfall populates the list of internal groups from the synced IdPs in Directory Sync. You must select at least one group.
Monitor all, except: Choose this option to exclude one specific, or a set of, internal groups from being monitored. Once you choose this option, Nightfall populates the list of internal groups from the synced IdPs in Directory Sync. You must select the required users.
Monitor specific: Choose this option if you have external user groups defined in your IdP and would like to monitor one specific or a set of external groups. Once you choose this option, you must select at least one external user group to monitor then hit the enter key.
Monitor all, except: Choose this option if you have external user groups defined in your IdP and would like to exclude one or more external groups from being monitored. Once you choose this option, you must select at least one external user group to monitor then hit the enter key.
Before understanding the Permission filters, we must understand Google's General Access feature.
The general access feature in Google Workspace consists of three types of access, which are as follows.
Restricted: Files with this permission can only be accessed by users who have been granted access.
Target Audience: Files with this permission can be accessed by the users of the selected target audience group. There is a default target audience that gets created when the Google workspace is provisioned. This target audience has the same name as provisioned in the Google Workspace and includes all members of the organization. You can refer to this Google document to learn more about the target audiences.
Anyone with the Link: Files with this permission can be accessed by any user who has the file link.
Nightfall also provides inclusion and exclusion of files in policy scope that resembles the General Access sharing principle in Google Workspace. The Nightfall General Access permission options are as follows.
Restricted: Choose this option to scope monitoring to files with restricted access.
Shared with target audiences: Choose this option to scope monitoring to files shared with target audiences within your Google Workspace environment.
Anyone with the link: Choose this option to scope monitoring to files shared with anyone with a link.
The Nightfall Detection Rules consist of a single or multiple detectors. You can use this filter to either include all the detection rules or include only specific detection rules. Note that upon a download event, Nightfall will check if the downloaded file has been previously scanned, and results matched at least one of the selected detection rules (i.e. The file is not rescanned upon download).
All: If you select this option, all the detection rules are included.
Monitor Specific: If you select this option, you must also select the required detection rules. Nightfall scans your files only for the selected detection rules.
Once you zero down the policy Scope to the required devices and originating domains, you must now define the trigger actions that can be termed as exfiltration events.
Nightfall provides you two types of triggers that you can set as exfiltration events.
Browser Uploads: In this section, if an asset is uploaded through a browser to an online portal (for example social media website), you can define such events as exfiltration events.
Cloud Syncing: In this section, if an asset is uploaded to an online cloud store application (for example Google Drive), you can define such events as exfiltration events.
The steps to use the above triggers are elaborated in the following sections.
Ensure that you have configured domain collections before using the use the browser uploads option.
To monitor browser uploads:
Select the Browser uploads to option.
Select one of the following options.
Any Domain: If you select this option, Nightfall monitors your uploads done to any domain on the Internet.
Domain in: If you select this option, you must additionally also select the domain collections, created in the domain collections section. Nightfall monitors the uploads done to all the domains that belong to the selected domain collections.
Once you select a domain collection, it is displayed on the screen and greyed out from the drop-down menu. You can use the drop-down menu to select additional domain collections.
Domain Not in: If you select this option, you must additionally also select the domain collections, created in the domain collections section. Nightfall does not monitor the uploads done to all the domains that belong to the selected domain collections.
Once you select a domain collection, it is displayed on the screen and greyed out from the drop-down menu. You can use the drop-down menu to select additional domain collections.
In this option, you can either choose to monitor uploads done to every cloud sync app or select specific cloud sync apps to which the uploads must be monitored.
Select the Cloud Syncing to option.
Select one of the following options.
Any Storage Apps: If you select this option, Nightfall monitors the uploads done to every cloud sync storage applications.
Specific Storage App(s): If you select this option, you must additionally select the storage apps. Nightfall monitors the uploads done to the selected storage apps.
Once you select a cloud storage application, it is displayed on the screen and greyed out from the drop-down menu. You can use the drop-down menu to select additional cloud storage apps.
In this final stage, you assign a name to the policy, verify your configurations, and create the policy.
Enter a name for the policy.
(Optional) Enter a description for the policy.
Click Next.
Verify if all the policy configurations are set up as per your requirements.
(Optional) Click back or click on any specific stage to modify any of the policy configurations.

The Summary tab for a Browser upload action is as follows.
The Summary tab for a Cloud storage app event is as follows.
The Summary tab also displays the timeline when the event was created. You can also add comments on the Summary tab. The comments added by you can be viewed by other users as well.
The comment is displayed as follows.
This tab displays the details of the asset (with sensitive data) that was uploaded to a domain or cloud storage app. The asset tab also displays a number in brackets. This number indicates the number of assets that were uploaded as part of the event.
In the following image, there is a single asset that was uploaded and it triggered the event.
In the following image, there were two assets which were uploaded and these four uplaods together triggered the event.
In such cases when there are multiple assets involved, you can use the drop-down menu to switch between assets and view the asset details.
The Assets tab displays the following details.
Name: The name of the asset uploaded.
Where: The location of the asset in the device.
Medium: The medium used to upload the asset. This can be browser or cloud storage app.
The Assets tab also contains the Asset History section. This section displays the source or origin from where the asset was downloaded.

Important
If you upload the same file to multiple browsers (say 3), 3 exfiltration events are generated. However, if you upload multiple files to the same browser, only a single event is generated.
If multiple violations are recorded within a span of five minutes on the same browser or cloud storage app, all the violations are clubbed under a single exfiltration event. The #assets-tab of this event displays the details of each asset.
However, if you upload multiple files to different browsers or upload multiple files to different cloud storage apps, within a span of five minutes, a separate exfiltration event is generated for each of the uploaded file.
You can perform the following actions on all the three tabs. These actions are present at the bottom.
Copy Event Link: This action copies the link of the event to the clipboard.
Acknowledge: This action modifies the status of the event to Acknowledged.
Notify Slack: This action sends a Slack notification about the event to the recipient configured in the #admin-alerting section.
Notify Email: This action sends an Email notification about the event o the recipient configured in the #admin-alerting section.
Resolve: This action resolves the event and modifies the status to resolved.
Ignore: This action ignores the event and modifies the status to ignored.
Asset: The asset window displays the details of the asset and the history of the asset. You can also choose to view historic asset data. If there are multiple assets in a single violation, you can choose which asset's details must be displayed.
The Scope section enables you to create an asset lineage based policy in which you can track the journey of an asset from source to destination.
Security administrators can set precise exfiltration policies to protect sensitive files that originate from high-value SaaS locations from being exfiltrated to unsanctioned destinations
High performance security teams can focus their energy and resources on monitoring assets from high value SaaS domains.
By combining content download origin to upload destination, organizations can extend their monitoring to cover any cloud application accessed through the browser, even those without direct API integration.
Allows security teams to monitor and prevent data exfiltration not just through direct browser uploads but also through cloud storage sync applications, providing a multi-layered defense against data leaks.
With lineage-based policies, organizations can proactively identify and manage risks associated with sensitive content movement, ensuring compliance with data security standards and preventing potential breaches before they occur.
The Scope page consists of two sections.
By default, Nightfall monitors all the macOS devices configured in your org. However, you can choose to exclude specific macOS devices from being monitored.
If you have a long list of assets, you can search for an asset by entering the device ID of the asset.
The Asset Origin filter allows you to limit the scope of the policy to only those assets which originated from a specific source. To use the asset origin filter, you must click Add Filter and select Asset Origin.
The Asset origin filter provides the following options:
Any Domain: If you select this option, Nightfall monitors the assets originated from any domain, present in any of the domain collections.
Domain in: If you select this option, you must additionally also select the domain collections, created in the domain collections section. In this case, Nightfall monitors only those assets that originated from a domain, which is a part of any of the selected domain collection(s).
Once you select a domain collection, it is displayed on the screen and greyed out from the drop-down menu. You can use the drop-down menu to select additional domain collections.
Domain Not in: If you select this option, you must additionally also select the domain collections, created in the domain collections section. In this case, Nightfall does not monitor those assets that originated from a domain, which is a part of any of the selected domain collection(s).
Once you select a domain collection, it is displayed on the screen and greyed out from the drop-down menu. You can use the drop-down menu to select additional domain collections.
Nightfall Exfiltration prevention for Salesforce allows you to configure alerts at the policy level and also at the integration level. Alerts can be sent in Salesforce by using the following alert channels.
Slack
Webhook
Jira Tickets
When you configure alert settings at the integration level, the alert settings apply to all the policies, created for the Salesforce integration. However, when you configure alert settings specifically for a policy, which is created in the Salesforce integration, the alert settings are applicable only for that specific policy.
This document explains how to configure alerts at the integration level. To learn about how to configure alerts at the policy level, read this document.

The Trigger section in Salesforce policies allows you to define the frequency of action that must be considered as an exfiltration event. In case of Salesforce policies, the download frequency is the trigger.
The download frequency can be defined as the number of downloads over a period to time. This allows you to set custom thresholds in terms of number of downloads over a specific period of time and can be useful to identify anomalous download patterns for specific locations, users or content type. This can be set in combination to other scoping capabilities.
In the Actions section, you can define the download action that must be considered as a potential exfiltration attempt by Nightfall. Nightfall allows you to set the frequency of downloads as the action.
To configure Actions:
Click the minimum number of files that must be the download threshold.
Set the time period within which the minimum no. of downloads must be considered as exfiltration event.
In the following case, an exfiltration event is created if, there are 2 or more downloads within a minute.
You must set the action frequency carefully. For example, consider that you set the action condition as 5 or more files, within 1 hour as shown in the following image. In this case, if a user downloads four assets, every 1 hour, the policy does not trigger a violation, since the Action condition does not match. So, a user can keep downloading four files every hour and get away with it.
This stage allows you to select automated notification channels or actions if a policy violation occurs.
This section allows you to send notifications to Nightfall users. The various alert methods are as follows. You must first turn on the toggle switch to use an alert method.
The alert configurations configured in this section describe the process of creating alerts at the policy level. Policy-level alerts apply only to the policy on which they are configured. To configure an alert on all the Salesforce Exfiltration policies, you must configure alerts at the integration level. To learn more about how to configure integration-level policies for the Salesforce integration, read
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 the document.
Automated actions allow you to configure automated remediation actions when an exfiltration attempt is detected by Nightfall policy. Nightfall supports the following automated actions for Salesforce. You can choose to implement the automated action immediately after detecting a download attempt or after some time.
To enable the automated action, you must turn on the respective toggle switch.
This action logs out the user from the Salesforce account. They cannot login until a Salesforce admin revokes the freeze on the account.
You must now select when exactly after detecting the event, the action must be triggered. if you select the Immediately option, the automated action is triggered immediately after the download attempt is made.
If you select the After option, you must select the time gap after which the automated action must be implemented.
You must now select when exactly after detecting the event, the action must be triggered. if you select the Immediately option, the automated action is triggered immediately after the download attempt is made.
If you select the After option, you must select the time gap after which the automated action must be implemented.
This section allows you to configure notifications to be sent to the end user whose actions triggered the violation.
The automation settings allow you to send notifications to end users. You can select one or both the notification methods. You must first turn on the toggle switch to use the automation option. The automation notification channels are as follows
Email: This option sends an Email to the user who attempted the download.
Slack: This option sends a Slack message to the user who attempted the download.
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 by their download attempt. You must turn on the toggle switch to use this option. End-users receive the remediation actions in an Email as an action item. The various available remediation actions for end-users are as follows.
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.
When end-users report alerts as false positive, you can choose the resolution method to be either Automatic or manual.
If end-users do not take any remediation action, you can set the frequency at which they must receive the notifications to take action.
Exfiltration policies allow you to monitor download events across your Salesforce environment. Through real-time download monitoring, you can identify insider risk and anomalous behaviour before it escalates to large scale security incidents. The following are supported and monitored by Nightfall for exfiltration activities,
Attachments & Files
Reports
Records & Objects
Download of any of the above information containers is an exfiltration activity for Nightfall, and if such activities breach a threshold set in one of the exfiltration policies in Nightfall, then Nightfall will flag it an exfiltration event. You can configure which users should receive notifications and what automatic actions must be taken when an exfiltration event is detected.
The detailed steps to configure the Salesforce Exfiltration policy is explained in the following documents.
In this stage, you select the Integration for which the policy is created. In this case, Salesforce integration must be selected.
Click Policies from the left menu.
Click + New Policy.
Select Exfiltration.
Select the Salesforce integration.
If the event monitoring module is not setup in Salesforce, event monitoring is displayed as "disabled" on the Scope page as shown in the following image.
This action revokes the permissions of the user. The user can now only view data across al Salesforce pages. They cannot download any data. This action assigns the user Salesforce's minimum access profile. You can learn more about this profile from this .
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 with the text Nightfall website, you must write <www.nightfall.ai|Nightfall website>.
The Scope section determines which areas of Nightfall needs to be monitored by Nightfall for Exfiltration. You can choose one or all of the following data types to be monitored.
Attachments & Files
Reports
Records & Objects
After you make the required selection, you can also add filters to monitor specific Salesforce users or Salesforce profiles.
