Problem
Given the following information about a network security implementation project:
"The network security layer is essential for most IT infrastructures and its various components are discussed in the following section. A network is as secure as the network manager makes it to be meaning that it is the network manager's responsibility to add as many types of network security as possible, within reason of the system. The main goal of security is to protect sensitive, confidential information. For our bank, it is critical that the security layer properly handles traffic between the bank and its customers, without allowing room for hackers and cybercriminals to access such information. Some common types of systems and devices that can be implemented into a security layer are firewalls, intrusion prevention systems, workload security, network segmentation, VPN, and access control."

b) What are some pros and cons?
