Overview

Use the Data Preferences settings for Trusted activity to define domains, URLs, Slack workspaces, cloud accounts, and Git repositories you trust.

Adding trusted activity prevents file activity in these locations from appearing on dashboards, user profiles, and alerts.

Trusted file activity is still captured and searchable in Forensic Search.

Considerations

To use this functionality, your role must have permissions to view and modify data preferences.

How it works

File events are considered trusted when an entry in your list of trusted activity matches file event metadata associated with the event. Metadata evaluated for trust includes: browser tab titles, URLs, Git URIs, account names, usernames, and email addresses.
If there is more than one domain associated with an event, all domains must be included in your list of trusted domains for the event to be trusted. If any domain associated with event is not in your list of trusted domains, the event is not trusted.
Trusted file activity is excluded from:
- Data on the Risk Exposure dashboard
- Alerts
- Contributing to risk severity scores (unless identified as a source with high-value data)
- File event counts for Watchlists and User Profiles
- Forensic Search results that include the Trusted Activity filter with the value Exclude

Configure trusted activity

To access trusted activity settings:

Sign in to the Code42 console.
Navigate to Administration > Environment > Data Preferences.
Select the Trusted activity tab.

Item		Description
a	View trust suggestions	Click to view domains that frequently generate untrusted events, with the option to add the domain to trusted activity. See Trust suggestions below for details.
b	Add trusted activity	Click to add trusted activity and select a type: Domain Trusts a wide variety of activity across an entire domain, including files uploaded via a web browser, sent from cloud sync apps installed on user devices, uploaded via Git push, and shared via cloud or email services monitored by Incydr. See Domain below for complete details. Specific URL path Trusts browser uploads to only part of a domain. For example, adding the URL path github.com/company trusts uploads only to the "company" repository and not to all of github.com. See Specific URL path below for complete details. Slack workspace Trusts files uploaded in a specific Slack workspace. See Slack workspace below for complete details. Account name OneDrive and Dropbox only For cloud sync apps installed on user devices, trusts activity in a specific account. For example, specifying the name of your corporate account enables you to trust that activity, without trusting activity in personal accounts. See Account name below for complete details. Git repository URI Trusts pushes to specific repositories via Git. See Git repository URI below for complete details.
c	Filter	Filter the list of entries by what the activity applies to.

Trust suggestions

Review domains that frequently generate untrusted events and quickly add them as trusted activity. Adding these domains as trusted activity removes file activity in these locations from dashboards, user profiles, and alerts. The list of suggestions updates regularly, based on activity in your environment.

For each suggestion, click Add to trusted activity Add_to_trusted_activity or Decline and remove from list .

Trust_suggestions

Domain

Adding trusted activity for a domain gives you the option to trust a wide variety of activity across the domain, including files uploaded via a web browser, sent from cloud sync apps installed on user devices, uploaded via Git push, and shared via cloud or email services monitored by Incydr.

Maintain confidentiality for users reporting misconduct
If your organization has established processes for users to report unethical behavior, harassment, discrimination, or other types of misconduct, consider adding the associated URLs to your list of trusted domains. For example, adding report-misconduct.example.com would prevent file activity on that domain from appearing on Code42 dashboards, user profiles, and alerts.

Trusted domain settings

Watch the video below for an overview of how to define a trusted domain. For more videos, visit the Code42 University.

Syntax and formatting requirements

Do not include https:// .
Including www is optional. The www prefix is ignored when evaluating trust.
Only the domain is evaluated for trust. The protocol (https://) and characters after the top-level domain (TLD) are ignored. For example, for file activity on https://subdomain.corp.example.com/pages, only subdomain.corp.example.com is evaluated for trust.
For email activity, a value of example.com trusts activity from all users with email addresses on the example.com domain. Trusting specific email addresses is not supported.
Optionally, use the asterisk (*) character as a wildcard for partial domain names. For example, enter *.example.com to trust all subdomains of example.com. See more guidance and warnings about wildcards below.
Review the Recommendations and Examples tabs on the add/edit screen for additional guidance.

Trusted scope

The Trusted scope settings enable you to define more specific criteria for which activity on a domain is trusted. Select one or more options:

Files uploaded to this domain via a web browser: Activity is trusted if the domain is included in the browser URL or tab title.
Files synced to cloud storage by desktop apps: Activity is trusted if the username signed in to the cloud sync app is on the domain. Click Edit to adjust which specific apps are trusted.
Files shared from a cloud storage service monitored by Incydr: Activity is trusted if the user it's shared with is on this domain. Click Edit to define which cloud storage services are trusted.
Files shared from an email service monitored by Incydr: Activity is trusted if the email recipient is on the domain. Click Edit to choose which email services are trusted.
Files uploaded via Git push: Activity is trusted for Git push events to this domain.

Editing trusted scope details
Clicking the Edit link enables you to better identify risk in unmonitored locations. For example, if your company's only approved cloud storage solution is OneDrive, deselect Box and iCloud to define that activity as untrusted, even if the email address signed in to the account is on your domain.

Identify sources with high-value data

Available for domains, URL paths, Slack workspaces, and Account names

The Is this also a high value source of company information setting enables you to define if files acquired from this trusted location are a potential risk if they are exfiltrated later.

Yes: Events for files acquired from this location and later sent to an untrusted destination have a risk score and source risk indicator applied. This enables you to trust uploads to a destination, but still apply risk to files downloaded from that destination and later moved to unmonitored or untrusted locations.
No: Events for files acquired from this location and later sent to an untrusted destination are not identified as a risk.

Wildcards

Use wildcards carefully to minimize risk
Using a wildcard character may lead to unintentionally trusting unknown or malicious domains.

A trusted domain value of example* trusts not only example.com, but also any domain starting with example, such as example.fake.com, examplenotyourrealdomain.com, and example.info.

To trust both a parent domain and all subdomains, do not use an overly inclusive wildcard value, such as *example.com. Instead, add these two values to minimize risk:

example.com
*.example.com

Since the first entry does not include a wildcard, it only trusts activity that matches the example.com domain exactly. In the second entry, including a period (.) after the wildcard ensures only subdomains of your legitimate domain are trusted.

Trusted domain examples

The table below provides examples of whether file activity is trusted based on the combination of the trusted domain entry and where the file activity occurred.

Yes = Activity on this domain is trusted for the supplied trusted domain entry
No = Activity on this domain is not trusted for the supplied trusted domain entry

	Trusted domain entry
	<<< More secure Less secure >>>

Activity on:	example.com	*.example.com	example	*example.com	example*	example
www.example.com	Yes	No	No	Yes	Yes	Yes
https://subdomain.example.com	No	Yes	No	Yes	No	Yes
www.not-example.com	No	No	No	Yes	No	Yes
www.example.fake.com	No	No	No	No	Yes	Yes
first.last@example.com	Yes	No	No	Yes	Yes	Yes

Specific URL path

Specific URL path entries trust activity for only part of a domain. For example, adding the URL path github.com/company trusts uploads only to the "company" repository and not to all of github.com.

The combination of domain and path define trusted activity.
All sub-directories of a path are also trusted. For example, an entry of github.com/company also trusts uploads to github.com/company/repository.
The path portion of the URL can contain wildcards (*), but the domain cannot include wildcards.
Do not include the protocol or query parameters. They are ignored when evaluating trust.

Watch the video below for an overview of how to define a trusted specific URL path. For more videos, visit the Code42 University.

Slack workspace

Trusting only specific Slack workspaces enables you to better identify risk in external Slack workspaces you don't control. For example, adding your corporate Slack workspace trusts file activity only within that workspace. Files shared in other workspaces are not trusted.

Only enter the workspace name (for example, "Acme Co."). Do not enter the workspace URL.
Wildcards are not supported in workspace names. If you include the * character, it is evaluated as part of the workspace name.

Watch the video below for an overview of how to define a trusted Slack workspace. For more videos, visit the Code42 University.

Account name

OneDrive and Dropbox only

Add your corporate cloud account name to trust file activity only within that account. This helps you better identify risk in personal accounts you don't control.

OneDrive

To trust a OneDrive account:

On a user device, find the OneDrive sync folder for the corporate account you trust. For help locating this folder, visit Microsoft Support.
In the Code42 console:
1. From the list of cloud services to trust, select OneDrive.
2. Enter the complete folder name in the Account name field. For example, OneDrive - Acme Co.
3. Click Save.

Dropbox

To trust a Dropbox account:

Sign in to dropbox.com with your administrator credentials.
Select Admin console > Settings > Team profile. Note the Display name.
In the Code42 console:
1. From the list of cloud services to trust, select Dropbox.
2. In the Account name field, enter the Display name plus the word "Dropbox." For example, if your Display name is "Acme Co," enter "Acme Co Dropbox".
3. Click Save.

Trusted activity - Account name

Account name considerations

For OneDrive, trust is only evaluated for OneDrive for Business accounts. Personal accounts cannot be trusted.
For OneDrive, the sync folder name on user devices is determined by the name in your Microsoft console at the time the sync folder was created. Therefore, if your Microsoft account name has ever changed, you may have devices with different sync folder names. Add a separate trusted activity entry for each unique sync folder name in your environment.
Wildcards are not supported in account names. If you include the * character, it is evaluated as part of the account name.
Incydr Professional, Enterprise, Horizon, and Gov F2 require Code42 app version 1.5.0 or later for OneDrive and version 1.6.0 or later for Dropbox.
Incydr Basic, Advanced, and Gov F1 require Code42 app version 10.3.0 or later.

Git repository URI

Incydr Professional, Enterprise, Horizon, and Gov F2 only

Add a Git repository URI to trust Git pushes to this location.

All sub-directories of the repository are also trusted.
The URI scheme, user, and the trailing “.git” are ignored. For example:
- To trust all repositories in your company account at ssh://git@example.com:account/, enter example.com:account/
- To trust a specific repository at ssh://git@example.com:account/repository.git, enter example.com:account/repository
To trust browser uploads to this location, you must also add a Specific URL path entry.

Trusted activity recommendations for source code repositories

How you configure trust for Git activity varies based on your source control application and repository locations.

General guidelines

To trust Git activity for all repositories on a domain, use the Domain trusted activity type and select the trusted scope Files uploaded via Git push. You do not need to specify individual URI values. The Domain entry applies trust to both Git browser uploads and Git push activity.
To trust only some locations on a domain, you must add two trusted activity types:
- A Specific URL path entry to trust browser uploads
- A Git repository URI entry to trust Git push activity

Specific examples

Github: Add trusted activity entries for both Specific URL path and Git repository URI.
Gitlab: Add a single Domain trusted activity entry. If the domain is already on your list of trusted activity, click the edit icon and then select Files uploaded via Git push in the list of Trusted scope options.
Azure DevOps: Add trusted activity entries for both Specific URL path and Git repository URI.
BitBucket (cloud): Add trusted activity entries for both Specific URL path and Git repository URI based on your workspace name.
BitBucket (on-prem): Add a single Domain trusted activity entry. If the domain is already on your list of trusted activity, click the edit icon and then select Files uploaded via Git push in the list of Trusted scope options.
