How do you virus scan a file being uploaded to your java webapp as it streams? [closed]

Answer 1

You might investigate ClamAV or ClamWin. They are open source virus scanners, ClamWin is based on ClamAV. You should be able to modify one of these (if someone hasn't already) to do what you want.

On the other end, you might consider simply dropping the streamed files into a directory and letting a scanner monitor that particular directory.

Kaspersky (and others probably) appears to have several ways to handle this at an enterprise level: http://usa.kaspersky.com/business-security/targeted-solutions

The internet gateway product might be of most relevance. It looks like it supports Checkpoint, Squid Proxy Server, and Microsoft.

Here is there download page for trials and documentation: http://usa.kaspersky.com/downloads/documentation

At an enterprise level you might decide to get an appliance (Cisco ACE for example) which off-loads the SSL and then use one of these options (or Cisco IOS Intrusion Prevention System (IPS) with Cisco firewalls). I have several clients with Cisco ACE devices, but am investigating virus detection at the firewall.

Answer 3

Check out Clamv ( http://www.clamav.net/ ) It is a open source anti-virus, and you can scan a stream. So you do not need to save the file for scanning it.

http://linux.die.net/man/1/clamscan

Scan a data stream: cat testfile | clamscan -

So it is quite easy, start the clamscan process with the - arg. write the file content to the stdin, and wait for the result code.

During your testing, you can use the EICAR file, which is a file dedicated for checking if an anti-virus is working. http://en.wikipedia.org/wiki/EICAR_test_file
