Exercise 64: Maine Asylums, LLC


The list of general firewall concepts that you generate for the customer should include the following:

Pros:

  • Can prevent unwanted traffic from entering the network.

  • Can monitor outbound traffic as well as inbound.

  • Can prevent unauthorized access or attacks.

  • Can be implemented in a variety of ways (packet filtering, application level, and so on).

  • Is relatively inexpensive to implement.

Cons:

  • Could prevent legitimate data from being received.

  • Can only protect at the layers it is targeting. A packet filter firewall, for example, is still susceptible to upper level attacks. This can lead to a false sense of security.

Implementing a firewall simply involves defining what you want to allow and disallow, and then installing and configuring the appropriate package for such.
