Overview

Introduction

The Understanding the Concepts of Internet, Intranet and Extranet module provides you with the instructions and devices to develop your hands on skills in the following topics.

  • Managing Security Zones in Internet Explorer
  • Configuring Windows Firewall and Blocking Applications
  • Install and Configure Routing and Remote Access

Exercise 1 - Managing Security Zones in Internet Explorer

In this exercise, you will learn to configure security zones in browser for intranet and the Internet. You will also learn to configure Windows Firewall.

Exercise 2 - Configuring Windows Firewall and Blocking Applications

The Windows Firewall protects the system from network attacks. The firewall protects the system from attack by inspecting incoming and outgoing network traffic and applying rules to decide whether traffic should be allowed or blocked.

You can create inbound or outbound rules for incoming and outgoing traffic respectively. There are three network location profiles in Windows Firewall that can be independently configured. These are the Domain networks, Home or work (private) networks, and Public networks profiles. Only one of these profiles can be active at a time.

Domain profile

This profile is automatically activated when a computer is connected to an Active Directory (AD) domain via an internal network.

Private profile

This profile may be chosen by the user when a computer is connected to a non-domain network that is at the user’s home or work.

Microsoft recommends more restrictive firewall settings for this profile than for the domain profile.

Public profile

This profile may be chosen by the user when a computer is connected to a public non-domain network.

Microsoft recommends the most restrictive settings for this profile.

Exercise 3 - Install and Configure Routing and Remote Access

The Routing and Remote Access service in Windows Server 2008 R2 supports remote user or site-to-site connectivity by using virtual private network (VPN) or dial-up connections. Routing and Remote Access consists of the following components:

Remote Access

The remote access feature provides VPN services so that users can access corporate networks over the Internet as if they were directly connected. Remote access also enables remote or mobile workers to use dial-up communication links to access corporate networks.

Routing

Routing and Remote Access includes a full-featured software router. It offers routing services to businesses in local area network (LAN) and wide area network (WAN) environments.
