| Abstract | The computer network at IOT is an integral part of everyday work. All files, programs, simulations and data are very important and security is of the utmost concern.The firewall is one of the most important security devices in our network, and must be maintained at a level such that it can provide a reliable and efficient security barrier for our network.To meet this end, it has become necessary to update the current firewall system (a single machine) to a dual-machine system so that if one of the firewalls crashes the network will still be operational and secure.A number of proposals with which to accomplish this are presented in this report, and a recommendation made on the method of implementation. |
