Collection configuration and app installation

Depending on the set up collection method, you can configure and install the app in three ways:

Create a new collector and install the app. Create a new Sumo Logic Cloud-to-Cloud (C2C) source under a new Sumo Logic Collector and later install the app; Or
Use an existing collector and install the app. Create a new Sumo Logic Cloud-to-Cloud (C2C) source under an existing Sumo Logic Collector and later install the app; Or
Use existing source and install the app. Use your existing configured Sumo Logic Cloud-to-Cloud (C2C) source and install the app.

info

Use the Cloud-to-Cloud Integration for Digital Guardian ARC to create the source and use the same source category while installing the app. By following these steps, you can ensure that your Digital Guardian ARC app is properly integrated and configured to collect and analyze your Digital Guardian ARC data.

Create a new collector and install the app

To set up collection and install the app, do the following:

Select App Catalog.
In the 🔎 Search Apps field, run a search for your desired app, then select it.
Click Install App.
note
Sometimes this button says Add Integration.
In the Set Up Collection section of your respective app, select Create a new Collector.
1. Collector Name. Enter a Name to display for the Source in the Sumo Logic web application. The description is optional.
2. Timezone. Set the default time zone when it is not extracted from the log timestamp. Time zone settings on Sources override a Collector time zone setting.
3. (Optional) Metadata. Click the +Add Metadata link to add custom log Metadata Fields. Define the fields you want to associate, each metadata field needs a name (key) and value.
  - A green circle with a check mark is shown when the field exists and is enabled in the Fields table schema.
  - An orange triangle with an exclamation point is shown when the field doesn't exist, or is disabled, in the Fields table schema. In this case, an option to automatically add or enable the nonexistent fields to the Fields table schema is provided. If a field is sent to Sumo that does not exist in the Fields schema or is disabled it is ignored, known as dropped.
4. Click Next.
Use the new Cloud-to-Cloud Integration to configure the source.
In the Configure section of your respective app, complete the following fields.
1. Key. Select either of these options for the data source.
  - Choose Source Category and select a source category from the list for Default Value.
  - Choose Custom, and enter a custom metadata field. Insert its value in Default Value.
Click Next. You will be redirected to the Preview & Done section.

Post-installation

Once your app is installed, it will appear in your Installed Apps folder, and dashboard panels will start to fill automatically.

Each panel slowly fills with data matching the time range query and received since the panel was created. Results will not immediately be available, but will update with full graphs and charts over time.

Use an existing collector and install the app

To setup source in the existing collector and install the app, do the following:

Select App Catalog.
In the 🔎 Search Apps field, run a search for your desired app, then select it.
Click Install App.
note
Sometimes this button says Add Integration.
In the Set Up Collection section of your respective app, select Use an existing Collector.

Viewing the Digital Guardian ARC dashboard

All dashboards have a set of filters that you can apply to the entire dashboard. Use these filters to drill down and examine the data to a granular level.

You can change the time range for a dashboard or panel by selecting a predefined interval from a drop-down list, choosing a recently used time range, or specifying custom dates and times. Learn more.
You can use template variables to drill down and examine the data on a granular level. For more information, see Filtering Dashboards with Template Variables.
Most Next-Gen apps allow you to provide the scope at the installation time and are comprised of a key (_sourceCategory by default) and a default value for this key. Based on your input, the app dashboards will be parameterized with a dashboard variable, allowing you to change the dataset queried by all panels. This eliminates the need to create multiple copies of the same dashboard with different queries.

Overview

The Digital Guardian ARC - Overview dashboard offers a centralized view of data activities, enabling security analysts to monitor and secure sensitive information effectively. It highlights critical metrics such as total activities, blocked actions, unauthorized PKI activities, and rule violations for immediate visibility into security events. Analysts can track network activity by protocol (for example, HTTP, IPsec) and identify operational types like file creation, deletion, and transfer. File type access insights helps you to detect malicious files or unauthorized usage, while top users, computers, and applications provide a snapshot of entities generating the most activity.

The dashboard includes geolocation maps for sender and recipient activity to identify unusual or risky data transfers across regions. It also highlights potentially risky geographies associated with flagged behaviors. Authentication insights, such as failed login attempts, enable analysts to investigate credential misuse or brute-force attempts. Process monitoring lists metadata like file size, path, and user domain to identify risky operations. Historical activity trends help detect abnormal surges or patterns.

This tool is particularly effective for detecting incidents, managing insider threats, and ensuring compliance by tracking rule-violated activities. It supports threat-hunting efforts by correlating risky behaviors with geolocation and operational context. The focus on endpoint activity, unauthorized operations, and certificate analysis strengthens an organization’s data security posture. Security analysts can leverage these insights to identify and mitigate risks proactively, securing critical assets and sensitive data. The dashboard integrates seamlessly with Digital Guardian ARC, enabling a robust framework for real-time monitoring and investigation.
