| We're excited to introduce the new CrowdStrike Falcon FileVantage app for Sumo Logic. This app leverages the Sumo Logic Cloud-to-Cloud CrowdStrike FileVantage source that collects FileVantage logs from CrowdStrike. It enables the detection of unauthorized or high-risk file changes, policy violations, and suspicious activities that may indicate potential threats or compliance breaches. [Learn more](/docs/integrations/saas-cloud/crowdstrike-falcon-filevantage/). |

|
|
||
| The Sumo Logic app for CrowdStrike Falcon FileVantage enables security analysts to monitor and analyze file integrity across your environment. Leveraging the CrowdStrike Falcon FileVantage data helps detect unauthorized or high-risk file changes, policy violations, and suspicious activity that may indicate potential threats or compliance breaches. | ||
|
|
||
| Key features of the CrowdStrike Falcon FileVantage app include: | ||
|
|
||
| - **File integrity monitoring**. Obtain a comprehensive overview of file changes, organized by severity and type, including write, delete, rename, and permission changes. Additionally, you can gain insights into file changes based on the operating system version and view detailed information, such as rule violations and suppressed changes. | ||
| - **Host based monitoring**. Monitor the hosts, users, and processes involved in the file modifications to identify anomalies. | ||
| - **Policy violation detection**. Identify high-risk file activities and policy violations, focusing on severity, suspicious file creations, and deletions. Analyzing trends over time helps detect spikes in malicious activity. | ||
|
|
||
| Use cases for the CrowdStrike Falcon FileVantage app include: | ||
|
|
||
| - **Security monitoring**. Detect unauthorized or unusual file activities in real time, such as critical file deletions or configuration changes. | ||
| - **Compliance**: Monitor adherence to file integrity policies and flag violations that might impact compliance with regulatory requirements. | ||
| - **Threat investigation**. Investigate suspicious file modifications to uncover potential breaches or insider threats. | ||
| - **Host Activity Analysis**. Analyze file changes at the host level to identify risky behaviors or compromised endpoints. | ||
|
|
||
| The Sumo Logic app for CrowdStrike Falcon FileVantage is an essential tool for security teams. It provides the visibility and intelligence needed to detect and respond to file-related threats, ensuring data integrity and compliance across the organization. | ||
|
|
||
| :::info | ||
| This app includes [built-in monitors](#crowdstrike-falcon-filevantage-monitors). For details on creating custom monitors, refer to [Create monitors for CrowdStrike Falcon FileVantage app](#create-monitors-for-crowdstrike-falcon-filevantage-app). | ||
| ::: | ||
|
|
||
| ## Log types | ||
|
|
||
| This App uses Sumo Logic’s [CrowdStrike FileVantage Source](https://help.sumologic.com/docs/send-data/hosted-collectors/cloud-to-cloud-integration-framework/crowdstrike-filevantage-source/) to collect the FileVantage logs from CrowdStrike. | ||

| ## Set up collection | ||
|
|
||
| Follow the instructions provided to set up [Cloud-to-Cloud Integration for CrowdStrike Falcon FileVantage Source](/docs/send-data/hosted-collectors/cloud-to-cloud-integration-framework/crowdstrike-filevantage-source/) to create the source and use the same source category while installing the app. By following these steps, you can ensure that your CrowdStrike Falcon FileVantage app is properly integrated and configured to collect and analyze your CrowdStrike Falcon FileVantage data. | ||
|
|
||
| ## Installing the CrowdStrike Falcon FileVantage app | ||
|
|
||
| import AppInstall2 from '../../reuse/apps/app-install-v2.md'; | ||
|
|
||
| <AppInstall2/> | ||
|
|
||
| ## Viewing CrowdStrike Falcon FileVantage dashboards | ||
|
|
||
| import ViewDashboards from '../../reuse/apps/view-dashboards.md'; | ||
|
|
||
| <ViewDashboards/> | ||
|
|
||
| ### Overview | ||
|
|
||
| The **CrowdStrike Falcon FileVantage - Overview** dashboard provides a comprehensive overview of file and directory activity, helping security analysts monitor file integrity and identify potential risks. It provides a total count of the file changes, categorizing them by severity—**Critical**, **High**, **Medium**, and **Low**—to prioritize investigations. Suppressed changes, which are ignored due to predefined policies, are also highlighted. | ||
|
|
||
| Key metrics include file change types (**WRITE**, **RENAME**, **READ** **PERMISSION**, **OTHERS**, **DELETE**), displayed in an easy-to-read pie chart for quick analysis. The dashboard tracks changes by operating system, identifies top hosts and users making changes, and highlights threats or anomalies. | ||
|
|
||
| The dashboard also shows the monitoring rules that triggered the most changes, assisting in policy refinement. A detailed table of recent file activities, including timestamps, hostnames, file paths, severities, and associated policies, is provided. Overall, the dashboard strengthens the detection and response to unauthorized or suspicious file activities. <br/> <img src={useBaseUrl('https://sumologic-app-data-v2.s3.us-east-1.amazonaws.com/dashboards/Crowdstrike+Falcon+FileVantage/Crowdstrike+Falcon+FileVantage+dashboard.png')} alt="CrowdStrike Falcon FileVantage Overview" /> | ||

| ### Security | ||
|
|
||
| The **CrowdStrike Falcon FileVantage - Security** dashboard is tailored for security analysts to monitor high-risk file actions and potential policy violations. It categorizes file activities based on severity (**CRITICAL**, **HIGH**, **LOW**, **MEDIUM**) and action types, such as file creation, deletion, renaming, and attribute changes. This categorization helps analysts prioritize their responses to significant security events. | ||
|
|
||
| The dashboard tracks high-risk actions over time, enabling security teams to identify patterns or spikes in suspicious activity. There is also a dedicated section for policy violations, which lists instances where file changes conflict with configured security policies. This section includes details such as affected files, associated rules, and timestamps. | ||
|
|
||
| Additionally, security analysts can review file deletions with specific details, including file paths, user names, and originating countries. The severity trends are visually represented, providing a clear overview of security incidents over time and helping teams identify escalation points. | ||
|
|
||
| While the dashboard provides placeholders for tracking malicious file changes and directory changes, data in these sections requires specific configuration based on the environment. Finally, the **Host-Based Change Monitoring** table offers detailed insights into the hosts and host groups involved in file changes, assisting in pinpointing areas that need further investigation. Overall, this dashboard is a vital tool for ensuring file integrity and effectively mitigating risks. <br/> <img src={useBaseUrl('https://sumologic-app-data-v2.s3.us-east-1.amazonaws.com/dashboards/Crowdstrike+Falcon+FileVantage/Crowdstrike+Falcon+FileVantage+Security.png')} alt="CrowdStrike Falcon FileVantage Security" /> | ||
