Default can I use CentOS as a antivirus / spam filter / HTTP AV gateway?

Hi all

I've been thinking about using CentOS on a Dell R200 server and turn
it into a firewall / network monitor / traffic shaper in our
datacentre, instead of using a dedicated firewall device.


One of the devices that I have been looking at, with my limited
budget, is the D-Link DFL 860 -
http://www.netdefend.eu/Product.aspx?m=15&ref=DFL-860


It provides AV, SPI, VPN, DOS, P2P, etc protection. Most of this can
be done with Linux as well, but I'm not 100% sure about the AV part.


How will I use / setup CentOS to check all traffic coming in & out
(HTTP, SMTP, POP3, IMAP, etc) for virusses and clean them? We host
both Windows & Linux servers, and I'm not too worried about the Linux
servers, but Windows needs a lot of extra protection.




well, pop/imap shouldn't need any virus scanning, that would be handled
at the SMTP transfer layer, by something like MailScanner + ClamAV (I've
used this combination), or spamassassin+clamav, and others.


http virus scanning can be done by using Squid as a transparent web
proxy agent and squid plugins. I've never attempted this myself, so I
can't give you the exact recipe.

ssshhh!!! Don't tell Trend Micro you are scanning for viruses at the
gateway ... they don't like that term :-D

Are you saying I'm not allowed todo this, and will be violating a patent
right for building my own network level virus scanner / anti-virus gateway?

I'm actually looking todo this on the network layer, rather than the
software layer. Is this possible with Linux?
