I am in a Windows environment, but in my investigations of the company (new to group) I found we have an HP-UX server running 11.3 which is from 2003. I am being told that it is at risk since it has no Virusscan software and is not being updated. Well that is Windows thinking and our virus software doesn't have anything for HPUX so I am wondering if:
1. We should be updating the OS in essence from 11.3 and how often?
2. Is there patching for HPUX?
3. Is there any virusscanning?
