Exercise 1 - Secure a Linux Terminal and Implement Logging Services

There is no doubt that as compared to Windows, Linux is more secure. Just like any other operating system, Linux has an in-built security model, which can be further fine-tuned. CentOS, being a flavour of Linux, carries the same security model. However, it is important to note that the out-of-the-box configuration cannot be highly secure. You must fine-tune the system as per your need and ensure that you have secured the system

In this exercise, you will learn to secure a Linux terminal and implement logging services.
