Firewalls, zones, and antivirus

The basic fundamentals of securing a VMware View environment involve only allowing the specific ports and protocols absolutely necessary for a functioning VDI. In addition, it also involves the use of Secure Sockets Layer (SSL) (as opposed to unencrypted traffic over port 80 and other ports) when available. In addition, requiring the use of PCoIP, as opposed to also allowing Remote Desktop Protocol (RDP) connections, can further increase security in the environment.

Within a given VDI solution, there are potentially several firewalls that come into effect. These firewalls include:

• Windows OS firewall: This firewall is used to restrict inbound and outbound traffic at the operating system layer

• Network firewall (internal): This firewall is used to restrict traffic within the internal LAN environment

• Network firewall (external/DMZ): This firewall is used to restrict traffic (typically) generated from the Internet

• Virtual firewall: This firewall is used to restrict...
