Built with Cisco Packet Tracer. In this example, a dual homed firewall is implemented in order to separate traffic going to the intranet systems and the public network. One NIC is used to send web based traffic outside of the network, Another NIC is used to send secure traffic to the internal network, Once Port (number) is used to send any allowed traffic from the the endpoint (number) to the internal network. This will allow the end user to access internal systems such as email and web server. The second port is used for web traffic isolation. Any unauthorized web traffic is isolated from the rest of the internal network.

Dual Homed Network

Secure Home Network

In this network, a data connection is sent to a wireless router to provide internet to the PC, laptop, and a smart TV

  1. Passwords - all defualt passwords were changed to a more secure passwords

  2. Any guest accounts were deleted

  3. Any open ports on the computers or router itself were disabled.

  4. Patches were applied

  5. Network traffic was monitored by an IDS (Snort). This was installed on the PC with 2 NICs.

  6. WPS was disabled on the router, This would prevent any devices connecting by a push of a button

  7. Firewall was enabled on the router - only allowed traffic was allowed to pass through

  8. Static IP addressing was used. No other devices are going to be connected., This would make IP address management easier to maintain.
