Exercise 1 - Configuring Firewall Rules Using Windows Firewall

A firewall protects your computer from unauthorized access by users or applications outside of your corporate network. To make the firewall effective, you need to define/edit the firewall rules. These rules analyze the packets coming to the computer or network and compare whether the specified conditions are satisfied and then allow/deny access to the computer or network accordingly. Windows Firewall application enables you to configure and edit firewall rules.

In this exercise, you will create firewall rules using Windows firewall and verify their efficiency in managing access to the computer.

Learning Outcomes

After completing this exercise, you will be able to:

• Verify the Enabled Network Connection
• Create a Windows Firewall Rule
• Test the Firewall Rule
• Reconfigure the Firewall Rule

Exercise 2 - Configuring Firewall Rules using Windows Firewall with Advanced Security

Windows versions including Vista, 2008, and later, provide another built-in application for system security - Windows Firewall with Advanced Security. This application offers an expansive view of firewall security and has additional features compared to the scaled down version of the firewall in Windows XP.

In this exercise, you will create firewall rules using the Windows Firewall with Advanced Security and verify their efficiency in securing your computer.

Learning Outcomes

After completing this exercise, you will be able to:

• Verify the Connection
• Create a Firewall Rule using Windows Firewall with Advanced Security
• Test the Firewall Rule
• Reconfigure the Firewall Rule

Exercise 3 - Configuring Firewall Rules using Remote Desktop

Remote desktop is a built-in feature of Windows XP and later versions. Remote desktop enables you to setup a connection with any remote computing device on your network such that you can access the desktop of the computer and operate its resources as if they were local on your computer. Although similar to a VPN connection, a remote desktop connection

Learning Outcomes

After completing this exercise, you will be able to:

• Setup a Remote Session
• Create a Firewall Rule
• Verify the Firewall Rule
• Reconfigure the Firewall Rule Using the Remote Desktop Connection

Exercise 4 - Configuring Firewall Rules from the Command Line Interface

Command Line Interface (CLI) is one of the methods of communicating with the operating system or other software such as applications. In CLI, you issue commands and receive responses in the format of text lines, delineated from each other by command prompts. CLI commands are powerful and can achieve more with each command because they communicate with the software directly. On the other hand, the CLI commands are not intuitive and you must remember the commands, the syntax, and the context to use them correctly.

Learning Outcomes

After completing this exercise, you will be able to:

• Verify Blocked Ping Packets
• Configure the Firewall using CLI Commands
• Verify the efficacy of the Firewall Rule
• Reconfigure the Firewall using CLI
