PCI / AV / Linux DB Servers

We're in a bit of an uncomfortable spot here... We're basically a Windows shop, our DB servers have internet access, and therefore our DB servers have AV software installed. We have periodically had to disable or even remove it on some of our larger database clusters as we have seen slow interconnect traffic with it enabled (Symantec Endpoint, mostly version 12 by this point). As soon as we remove Endpoint, interconnect ping times go back to where they should be and we move on.

We've just started a process of converting to Linux - supposedly we'll have all 240+ databases on 11.2.0.3 on Linux by the end of the year. We had somewhat assumed along the way that we would not be using AV software on our Linux DB servers: lower risk, fewer Linux viruses, &c.

Our PCI auditor doesn't seem to agree. To satisfy his requirements, we need some form our AV software installed. Or some other form of protection...

So - I guess my question is: people running production Linux environments - what do you do? How do you protect your servers?

Thanks!
