Application proxy firewalls are designed to examine every byte of a packet, making screening decisions based on content, not just IP address header information. How it works A wall is built between internal and external computers. If an outside computer wants to contact a computer within a private network it actually communicates with the firewall, which communicates with the internal computer. When to deploy Firewalls are employed to restrict access to critical applications. They will be deployed to protect Secure Access Applications within the VCCS intranet.
Firewalls facilitate access control.
Proxy Servers Definition Proxy Servers provide the ability to mask IP addresses from outside individuals. How it works Communications from the 'outside' are routed to the proxy server where they are rerouted to clients within the Intranet. Outside agents are denied access to a servers true IP address. When to deploy The primarily use of proxy servers is to provide an access path for customers from outside the intranet. Proxy servers will be deployed to protect Secure Access Applications being accessed from outside the VCCS network.
