Chapter 12 Instant Firewall A firewall is a system designed to prevent unauthorized Internet users from accessing the private network connected to the Internet. It defines access rules and monitors all data entering or leaving the network and blocks the data that does not satisfy the specified security policies. Dell Instant implements the Instant Firewall feature that uses a simplified firewall policy language. An administrator can define the firewall policies on an SSID or wireless network such as the Guest network or an Employee network. At the end of authentication, these policies are uniformly applied to users connected to that network. The Instant Firewall gives the flexibility to limit packets or bandwidth available to particular class of users. Instant Firewall treats packets based on the first rule matched.
