Anti-virus Scanning

Getting started

ClamAV is an open source antivirus engine for detecting trojans, viruses, malware and other malicious threats. It is used in a variety of situations including file scanning, email scanning, web scanning and end point security.

This feature is installed on all nais clusters. clamAV runs in its own pod with a separate pod running the REST api applications use. There is a service set up so all applications will be able to talk to the REST api using http://clamav.nais-system.svc.nais.local/scan. The REST api supports PUT or POST and can be tested using curl as well:

ClamAV has a REST API applications can use for scanning files and urls.

The REST API has one endpoint /scan that supports PUT or POST with form-data. It can be tested using curl as well:

# Example
curl -v -X POST -H "Content-Type: multipart/form-data" -F "file1=@/tmp/file_to_test"  http://clamav.nais-system.svc.cluster.local/scan
curl -v -X PUT --data-binary @/tmp/file_to_test  http://clamav.nais-system.svc.nais.local/scan
curl -v http://clamav.nais-system.svc.cluster.local/scan?url=url_to_file

See ClamAV documentation and ClamAV REST API for more information.
