The server that was untagged to this DMZ VLAN will have the DMZ ACL applied to the inbound/outbound traffic.  This was quite simple setup.  This issue now...

  • How can I secure a Windows XP workstation that is open to port 80 and hosting a website using IIS

    How can I secure a Windows XP workstation that is open to port 80 and hosting a website using IIS? The box is on the DMZ of our firewall for the time being. We will probably move it inside the firewall and open port 80 to it shortly.

  • Could a honeypot machine risk the secure network?

    If I place a honeypot machine on my dmz what are the possible consequences? We want to see the possible issues lurking around us to better prepare for them. If we have a susceptible machine unpatched and asking for it could the rest of the secured network be at risk?
