MCSE 70-293 Exam Prep: Planning and Maintaining a Microsoft Windows Server 2003 Network Infrastructure (2nd Edition)

O BJECTIVES

Starting a text devoted to networking with a chapter on security might seem odd, but only if you are still working with the assumption that security is only for secret government research laboratories. Security is now front and center in Windows Server 2003, permeating it from front to back, top to bottom. Thus, it is only fitting that we discuss security and server roles before anything else in this training guide.

Microsoft defines the "Planning and Implementing Server Roles and Server Security" objectives as follows :

Configure security for servers that are assigned specific roles.

• The key to configuring and implementing role-based server security is to recognize the different levels at which security must be implemented. Servers should be grouped in Organizational Units (OU) by role for the purpose of applying security settings to them in an administratively efficient manner.

Plan a secure baseline installation.

• Plan a strategy to enforce system default security settings on new systems.

• Identify client operating system default security settings.

• Identify all server operating system default security settings.

• Windows Server 2003 is the most secure network operating system, out of the box, ever produced by Microsoft. While planning and implementing your overall network security plan, you need to be able to identify and, if necessary, enforce the default security settings on servers and client computers.

Plan security for servers that are assigned specific roles. Roles might include domain controllers, Web servers, database servers, and mail servers.

• Deploy the security configuration for servers that are assigned specific roles.

• Create custom security templates based on server roles.

• Not all servers are created alike; this simple fact has been proven time and again to administrators who got caught with their proverbial pants down. To effectively secure servers with varying roles, you need to identify the threats and vulnerabilities that each server faces.

Evaluate and select the operating system to install on computers in an enterprise.

• Identify the minimum configuration to satisfy security requirements.

• A default, out of the box, installation of Windows Server 2003 may not be the best choice for your particular security requirements. Being able to identify the best operating system and the optimal security configuration for that operating system is an important part of your overall network security plan.
