Digital Guardian ARC

The Sumo Logic app for Digital Guardian ARC provides a comprehensive suite of dashboards and alerts to help security analysts monitor, detect, and respond to critical events within their data protection environment. Designed to integrate seamlessly with Digital Guardian's Advanced Reporting and Analytics (ARC), this app offers actionable insights into endpoint activities, user behavior, and policy violations to enhance data security.

Key features of the Digital Guardian ARC app include:

Real-time activity monitoring. Gain visibility into activities such as file creations, modifications, and deletions, categorized by operation type, file types accessed, and protocols used.
Risk-based alerts. Pre-configured alerts for blocked events, failed login attempts, and user activities originating from high-risk locations allow analysts to detect and respond to potential threats in real-time.
Policy enforcement analytics. The app provides insights into rule violation events, helping organizations monitor adherence to security policies and identify areas for improvement.
User and host analysis. Interactive charts display the top users, applications, and systems contributing to security events, helping analysts pinpoint risky behaviors or potential insider threats.
Geolocation insights. Visualize sender and recipient activities from high-risk or suspicious locations with geolocation maps, enabling targeted threat investigation and response.
Signature issuer intelligence. Monitor digital signatures for files and applications to ensure authenticity and detect any potential tampering or unauthorized software.

Use cases for the Digital Guardian ARC app include:

Identify unauthorized activities. Detect and investigate unauthorized file access, data exfiltration attempts, or suspicious behavior within the environment.
Enforce compliance. Track and address violations of security rules to maintain regulatory compliance and internal policy adherence.
Monitor risky user behavior. Proactively address risky activities, such as failed logins or data transfers to/from suspicious locations.
Accelerate incident response. Leverage real-time alerts and detailed activity logs to respond to potential threats or breaches quickly.

The Sumo Logic app for Digital Guardian ARC is an essential tool for security teams. It provides the visibility and intelligence needed to safeguard sensitive data, enforce security policies, and mitigate risks in real-time.

Set up collection

To set up the Digital Guardian Source, follow the instructions provided. These instructions will guide you through the process of creating a source using the Digital Guardian Source category, which you will need to use when 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.

Installing the Digital Guardian ARC app

To 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.
Click Next in the Setup Data section.
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.

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.
