Configure Mod Evasive

The goal of this lab is to configure the `mod_evasive` module for the Apache Web Server. First, we install and load `mod_evasive`. Its installation includes a default configuration file with values we can modify. One thing to configure is how many times a person can reload our site until they are denied. The conditions of the lab include the following. * firewalld is already running. * SSH is port 61613 which we need to connect to the server. * Apache is running on port 80. * Port 80 is already open. * SELinux is in enforcing mode. * The front end and back end are both up and running. * The back end is running on port 65535.
