Installing and configuring the 2004 ISA Server Firewall - Chapter 1

In fact today information security is playing an essential role, not a 'secondary' in all activities related to the application of information technology. I want to talk about the great role of IT application which has been happening in a dynamic way, not only purely as tools (Hardware, software), but really has been considered as a solution to many problems.

Starting from the early 90s, with a small number of IT experts, the knowledge is limited and the application of IT in production, transaction and management activities is still quite modest and only stops at the tool level, and sometimes I find these 'expensive' tools also cause some hindrance, not to bring practical effects to Organizations using it.

And those who are "most busy" ask themselves' what to buy the equipment to do atrium ?! it does not produce the product, and it does not help reduce the paperwork, how do we lose some useless money ?! Not far from regional neighbors like Thailand, Singapore, strong economies in the region and on the rise. Recognizing the superiority of IT application, and very soon they brought IT industry to apply to all activities, not only production, transaction, management but IT was brought to every home, everyone. And they also learn the skills to solve and control very creative work from these modern 'weapons'. Somewhere in Bill Gates' 'The Way Forward' excerpt refers to the tremendous value of information in the 21st century, an era of true information. This 'immaterial' precious entity, is gradually becoming a sought-after, rigorously controlled object, and a launching pad for all countries that want to develop strongly, quickly and 'lasting'. It is necessary to have the most powerful systems to control information, create information and bring this information into application effectively. The step-by-step world in technique 21 uses IT pedals to leverage and also to guide activities, bring people closer together, making Geographical differences no longer exist, easy to understand. each other and exchange with each other the most valuable, most special things.

Applying information technology in an effective and 'sustainable' way, is the top criteria of many countries today, Vietnam is no exception. In terms of an enterprise when applying IT to production, business always wants to have this. Efficiency is imperative, and 'sustainability' is also inevitable. From the perspective of a system security expert, when implementing an information system and building a tight and safe protection mechanism, this contributes to maintaining the system's 'sustainability'. information of that business. And we all understand that the value of corporate information is invaluable. Not only materially, what other values ​​cannot be measured as their reputation with customers, if the information traded with customers is stolen, then be taken advantage of with the different purposes.Hacker, attacker, virus, worm, phishing, these concepts are now unfamiliar, and are really a top concern of all information systems (PCs, Enterprise Networks, Internet, etc .). And therefore, all these systems need to be equipped with powerful tools, knowledgeable about how to deal with those frightening black forces. Who created this powerful enough firewall to be able to 'burn' every intention to infiltrate ?! Please be aware that first of all, it is the awareness of all employees in the organization to use the secure computer, the knowledge of the Security Administrators in that Organization, and ultimately the most powerful tools. serve this 'war'. These are the Firewall, from Personal Firewall to protect each Computer to the Enterprise Firewall capable of protecting an organization's Network system. And Microsoft ISA Server 2004 is such an Enterprise Firewall! A good product and a trusted friend to secure information systems.

CHAPTER 1: Deploying Network infrastructure with essential Services

The book is presented according to the actual implementation of ISA Server 2004 in an organization's Network model. The content of the book encapsulates the ISA Server 2004 system configuration issues to become a powerful Firewall that still satisfies the requirements of using remote services, serving both internal ISA Clients to access the Service. external (Internet), and external clients (Internet Clients) need to access the Services within the Organization Network.

Firewalls has always been one of the most complex configurable Network devices and maintaining its operation to protect the Network has faced many challenges for the Security Admin. Basic knowledge of TCP / IP and Network Services is needed to understand how a Firewall works. However, it is not necessary to become an expert on Network Infrastructure to use ISA Server 2004 as a Network Firewall.

This chapter will describe the following issues:

• Help you understand features available on ISA Server 2004
• Provide specific advice when using documents to configure ISA Server 2004 Firewall
• Describe detailed implementation practices (ISA SERVER 2004 Lab Configuration).

Understand the features on ISA Server 2004

ISA Server 2004 is designed to protect Network, prevent external intrusion and control access from within an organization's Internal Network. ISA Server 2004 Firewall does this through mechanisms that control what can be allowed through the Firewall and what will be blocked. We can imagine as simple as this: There is a rule imposed on the firewall to allow information to be transmitted through the firewall, then this information will be 'Passed', and vice versa without any rules. Which allows these information to pass, this information will be blocked by Firewall.

ISA Server 2004 Firewall contains many features that Security Administrators can use to secure Internet access, and also to ensure security for resources within the Network Internal. The book provides the Security Admin with an understanding of the general concepts and uses the most common, specific features on ISA Server 2004, through specific steps (Steps by Steps).

Firewalls do not work in a 'vacuum' environment, because we simply deploy the Firewall to protect something, be it a PC, a Server or a Network system with many services deployed. Web, Mail, Database .

We will have a complete guide on deploying the services needed for an organization's Network operation. How to install and configure these services. And the most important thing is that Network and Services must be properly configured before deploying Firewall. This helps us avoid the frustrating problems that arise when deploying ISA Server 2004.

Network Services and features on ISA Server 2004 will be installed and configured including:

• Install and configure Microsoft Certificate Services (Service provides Digital Documents for secure identification when dealing on the Network)
• Install and configure Microsoft Internet Authentication Services (RADIUS) Service for secure authentication of remote access via remote connections (Dial-up or VPN)
• Install and configure Microsoft DHCP Services (Service provides TCP / IP settings for nodes on Network) and WINS Services (Service provides the NETBIOS name query solution of the Networks on the Network)
• Configure the WPAD entries in DNS to support Autodiscovery and Autoconfiguration functions for Web Proxy and Firewall clients. Very convenient for ISA Clients (Web and Firewall clients) in an organization when they have to bring Computer from a Network (with an ISA Server) to another Network (with another ISA Server) and still automatically detect and work with Web Proxy Service and Firewall Service on this ISA Server.
• Install Microsoft DNS server on Perimeter Network server (The Network contains the Server provided online for external Clients, behind the Firewall, but also separate from LAN)
• Install ISA Server 2004 Firewall software
• Back up and restore ISA Server 2004 Firewall configuration information
• Use the ISA Server 2004 model (ISA Server 2004 Network Templates) to configure the Firewall
• Configure ISA Server 2004 clients types
• Create access policies on ISA Server 2004 Firewall
• Publish Web Server on a Perimeter Network
• Using the ISA Server 2004 Firewall acts as a Spam filtering SMTP relay (e-mails relay station, with the function of preventing Spam mails)
• Publish Microsoft Exchange Server services (Microsoft Mail and collaboration system, similar to IBM Lotus Notes)
• Configure ISA Server 2004 Firewall to act as a VPN server
• Create a site to site VPN connection between two Networks

Before implementing ISA Server 2004 Firewall configuration, be aware: This is a system to prevent attacks from the Internet and a Firewall with error configuration will facilitate Network intrusion. For these reasons, the most important thing that Security Administrators care about is How to configure the Firewall to ensure the safety of Internet access.

With its default configuration ISA Server 2004 prevents all incoming and outgoing traffic through the Firewall.

Obviously this is the most active and secure configuration that Admin can be assured from the start when operating ISA Server. And then to meet the legal requirements of accessing various Internet services (eg web, mail, chat, download, online games, etc.), the Security Admin will configure it to have ISA Server 2004 available. can meet the requirements allowed above.

The Securty Admin is always recommended: Create tests for configuring ISA Server 2004 in the Lab, before bringing these configurations into practice. We will be guided to configure the ISA Server 2004 Firewall properly and correctly through the ISA Server 2004 working interface. There may be mistakes in implementing the Lab, but the Admin is not worried because Make sure attackers can't take advantage of these vulnerabilities (unless the Lab Network is connected to the Internet .). On the Lab, the most important thing is to correctly understand the parameters configured, allow the offense and the Admin to draw the experience from these mistakes.

LAB instructs to configure ISA Server 2004 Firewall

We will use a Network Lab to describe the capabilities and features of ISA Server 2004. Administrators in practice should build a Test Lab similar to the model shown below (all parameters used). use). If the Admin Security does not have enough real devices like this Test Lab, it is possible to use the simulation model, from Virtual Software like

Microsoft's Virtual PC software (or VMWare) to create a virtual Lab model.

In this section, we will consider:

• How to configure Network for ISA Server 2004
• Install Windows Server 2003, and then upgrade (dcpromo) this Computer to a Domain controller (Domain's full control server)
• Install Exchange Server 2003 on this Domain controller and configure it as an Outlook

Web Access Site uses basic authentication (Basic authentication)

Network Diagram deploying ISA Server 2004

 

Model Network Lab - 7Computers.

However, Network Lab does not require all 7 Computers to run at the same time

This makes it easy for labs, especially virtual labs.

The Network model of this Organization has a Local Network ( Local Area Network LAN) and a Remote Network . Each Network has an ISA Server 2004 front panel that acts as a Firewall. All Computers on the Local Network are members of Domain MSFirewall.org , and this domain includes the ISA Server 2004 Firewall computer as well. All remaining Computers are not members of this Domain.

In the Network, Network Card (External interfaces) lab of ISA Server 2004 Firewalls have a connection that allows Internet access. Administrators should create the same configuration parameters to test the actual Internet connections from the client side after ISA Server 2004 Firewalls.

If we use the emulator, please note that we must set-up to 3 Virtual Networks on Test Lab. These are the Vitual Networks: The Domain Controller is located on the Internal Network , TRIHOMELAN1 Computer is on the third Perimeter Network and REMOTECLIENT virtual Network.

Pay attention to Virtual Lab : It is certain that on these Virtual Networks, computers are arranged on different Virtual Switches, to prevent information streaming Ethernet broadcast traffic, which can cause results. unwanted on virtual Lab .

Install and configure the Domain Controller on the Internal Network

A Computer is different from the ISA Server 2004 Firewall computer, which has the power to administer the entire Domain that is Domain Controller. Microsoft built the Domain model under the control of the Active Directory Service and Domain Controller as a tool to control that Domain. (manage all Clients and Servers providing Services in the Domain such as Web, Mail, Database server and including Servers)

In this lab we will configure a Windows Server 2003 domain controller, and deploy services such as DNS, WINS, DHCP, RADIUS, Microsoft Exchange Server 2003 on this domain controller itself.
