Understanding How Security Affects a Network
Given a scenario, predict the impact of a particular security implementation on network functionality (e.g., blocking port numbers, encryption, etc.).
Implementing security measures has an effect on the network. How much of an effect it has depends on which security measures are implemented and the habits of the network users. CompTIA specifies two examples of network security measures (blocking ports and encryption) and asks that you determine what effect the implementation of those measures will have on the network. The following sections help you prepare for this part of the exam.
Blocking Port Numbers
Port blocking is one of the most widely used security methods on networks. Port blocking is associated ...
