Listed below are the reasons for chosen countermeasures in addition with the benefits and limitations of each countermeasure.
1. Setting up a firewall will help eliminate open ports that network traffic travels in and out by disabling or limiting access to the port. The benefit of having a firewall is that it can close ports meaning closed doors. In other words, hackers won’t be able to enter the network infrastructure.
