Online Antivirus
Online Antivirus is an optional upload-security capability for BabelBird private deployments. After the module is enabled, files uploaded to the drive are scanned before they enter the enterprise file library. If a file contains a virus, trojan or other content identified as high risk by the virus database, the upload is blocked so the risky file cannot continue spreading through the drive.
The capability uses ClamAV as the scanning module. It can be deployed inside the enterprise private environment and supports pure intranet deployment. For isolated intranet, private network or restricted environments that cannot connect to the public Internet, virus database files can be updated periodically through an offline process.
Positioning
An enterprise drive is a major file intake point. Files may come from employee computers, external collaborators, suppliers, project members, mobile devices and historical migrations. Online Antivirus provides a security filter at the file-ingestion stage, blocking risky files before they become part of the managed file library.
Online Antivirus should be used together with permissions, sensitive content recognition, watermarking, audit logs, upload allow/deny lists and download controls. It answers whether a file carries malicious code; sensitive content recognition answers whether the file contains sensitive information; the permission system controls who can access and operate files.
Scanning Flow
| Stage | Description |
|---|---|
| User upload | Users upload files from web, desktop client, mobile app, sync or mapped drive |
| Enter scanning flow | The system sends the pending file to the antivirus module |
| ClamAV scanning | The scanner checks the file against the virus database |
| Result decision | Clean files continue into the drive; risky files are identified |
| Upload blocking | Files containing viruses are blocked and do not enter the enterprise file library |
The exact user prompt, log record and administrator visibility depend on deployment version, licensed modules and enterprise configuration.
Private And Intranet Deployment
The antivirus module can be deployed together with the BabelBird private environment, without sending business files to a third-party cloud scanning service. It is suitable for:
- Intranet or private network environments where business files cannot be uploaded to public antivirus services.
- Government, research, manufacturing, finance, design institutes, engineering projects and other scenarios with strict outbound-file restrictions.
- Environments where the drive, object storage, antivirus service and audit logs need to remain inside the enterprise network.
- Enterprises that want antivirus operations to be part of unified maintenance, backup, monitoring and change management.
In a pure intranet environment, operations teams need to maintain the virus database on a schedule. Virus database files can be imported through offline packages, internal mirrors or enterprise security maintenance workflows.
Virus Database Updates
ClamAV scanning quality depends on the virus database. For private deployments, establish a fixed update mechanism:
| Update method | Suitable environment | Notes |
|---|---|---|
| Online update | Servers can access the configured external update source | Virus databases can be updated automatically on schedule |
| Offline update | Pure intranet, private network or restricted network | Operations staff download virus database files externally and import them into the intranet through the approved security process |
| Internal mirror update | Multi-node or clustered deployment | Build an internal virus database source and synchronize scanning nodes from it |
The update cycle should follow the enterprise security policy. Organizations with frequent external file intake should update more often. In strongly isolated networks, virus database updates should be part of routine maintenance checks.
Usage Scenarios
External Collaboration Intake
When suppliers, customers, design institutes, project partners or external members upload files, file sources are diverse. Online Antivirus scans files before they enter project spaces, department spaces or material libraries, reducing the risk of malicious file propagation.
Historical Data Migration
When enterprises migrate data from local file servers, mobile drives, NAS or legacy drives into BabelBird, the file volume is large and sources may be complex. Enabling Online Antivirus helps discover and block risky files during migration.
Sync And Mapped Drive
When users write files through sync folders, mapped drives or the desktop client, Online Antivirus acts as a server-side defense line. It checks data entering the drive uniformly instead of relying only on endpoint antivirus software.
Material Libraries And Public Repositories
Material libraries, marketing materials, download areas, upload-only inboxes and cross-department public repositories often receive frequent uploads and downloads. Online Antivirus reduces the chance that risky files are downloaded, redistributed or reused by many people.
Configuration Recommendations
- Confirm whether the Online Antivirus module is purchased or enabled during private deployment.
- Define scanner location, resource configuration, scanning queues and exception alerts.
- For pure intranet environments, establish an offline virus database update process and record update time and version.
- Prioritize scanning for external collaboration, upload-only inboxes, public material libraries and migration folders.
- Use it together with upload allow/deny lists, file-type restrictions, sensitive content recognition, audit logs and permissions.
- Establish administrator review and handling procedures for blocked files so users do not repeatedly upload or bypass security policies.
