Automating malware scanning on S3 file uploads involves routing files through an asynchronous queue-based pipeline that uses ClamAV or cloud antivirus APIs to scan content before it is served. This ensures infected files are intercepted before reaching users.

Yes, you can use ClamAV or cloud antivirus APIs within an asynchronous queue-based pipeline to process file scans. This architecture offloads scanning from the main upload path, maintaining performance while verifying file safety through managed scan queues.

Quarantining infected files with auditable logging requires isolating flagged uploads into a restricted object storage state and recording the scan event details. This workflow maintains a clear audit trail while preventing access to malicious content.

A quarantine workflow tracks scan_status states like pending, scanning, clean, quarantined, and scan_failed to control file routing. Downloads are only permitted once a file reaches the clean state, while infected files are diverted to quarantine.

Preventing infected content from being served in a SaaS architecture requires implementing controlled access to object storage until an asynchronous malware scan completes. Files remain pending and inaccessible until verified clean by the scanning pipeline.

Routing files to downstream processing after a clean virus scan requires monitoring scan_status states and triggering post-scan routing only when the clean state is reached. This guarantees that infected files remain quarantined and unprocessed.
