As a security engineer, compare and contrast the pros and cons of deploying hetero vs homogenous networks. Which costs more? Which offers more protection? Why?

See below

Explanation:

In case of a homogeneous network, Skype is an example and OpenTable is an example of a heterogeneous network.

Homogeneous networks are easier to get started with since its all pre-integrated, and even the troubleshooting is more convenient if a problem arises. However, it then becomes a security concern if you choose to place all that power to a single vendor - known as ' monoculture'. One event can affect the entire network. On the other hand, a heterogeneous set up does not run this risk. Several different components are utilized which are not as vulnerable to security threats.

In conclusion, homogeneous networks cost more and heterogeneous networks are more secure.
