A sample from Chapter 7:
Network Access Protection (NAP), as you know, is a Windows Server feature that enforces health requirements on client computers as they attempt to connect to a company network. These health requirements can relate to the status of software updates, of antivirus protection, of host firewall status, or of spyware protection. NAP was first introduced in Windows Server 2008.
Although NAP doesn’t include any significant new features in Windows Server 2012, one important new feature, System Health Validator (SHV) Multi-configuration, appeared in Windows Server 2008 R2. This new feature falls within the one NAP objective listed for the 70-417 exam, Configure Network Access Protection.
Objectives in this chapter: Objective 7.1: Configure Network Access Protection
NAP can be deployed in many different configurations, depending on whether it is enforced through DHCP, VPNs, IPsec, or Remote Desktop Services Gateway, or 802.1x. If your knowledge of NAP has become rusty since you earned your last certification, it’s important to review how NAP enforcement is configured.
Most of NAP has remained the same since Windows Server 2008, but there is one new feature in NAP that falls within the Configure Network Access Protection objective: SHV Multi-configuration. For the 70-417 exam, you definitely need to know about this new feature, but one small feature might not be sufficient to represent the entire Configure Network Access Protection objective on the exam. For this reason, you might encounter one or more questions about NAP configuration that are similar to the ones you saw when you earned your Windows Server 2008 certification.
First, let’s review some basic NAP concepts. When a client computer first attempts to connect to a network, its first point of contact could be a DHCP server, a VPN server, or another type of device. In a NAP infrastructure, this first point of contact is configured as a NAP enforcement point, and the NAP client is configured to report its system status (called a statement of health or SoH) to this NAP enforcement point.
The NAP enforcement point uses the RADIUS protocol to forward the SoH and connection request to a Network Policy Server (NPS). The NPS server uses connection request policies to determine whether the client connection request will be processed by NAP. If evaluated by NAP, the client request is next processed by network policies, which provide potential instructions about whether to allow the connection, block the connection, or allow restricted access only to a remediation server or set of servers. The instructions of only the first network policy that matches the conditions of the connection request are followed.
Figure 7-1 shows an example of a simple NAP infrastructure.
Network policies usually include health policies as matching conditions. Health policies determine whether a NAP client matches an indicated state of failing or passing a health check according to an SHV. Windows Server includes one built-in SHV, Windows Security Health Validator.
Besides the network policies that assess the health compliance of NAP clients, an additional network policy is normally included to match clients that are not NAP-capable. These network policies include a condition named "NAP-Capable" whose value is configured as "Computer is non NAP-capable." (NAP-capable computers are ones that send an SoH.) Network policies created to match non-NAP-capable clients may be configured either to allow or block the connection request.
The following list further describes these components involved in NAP processing: ■ Connection request policies Rules that determine whether a connection request will be processed by network policies ■ Network policies Rules that compare the health of connection requests to health policy statements and accordingly allow access, block access, or allow remediated access to those requests. Network policies include conditions and condition values configured to match different types of clients. The Health Policy condition uses a health policy check to match a client. The NAP-Capable condition matches clients based on whether they have sent an SoH. The MS-Service class condition is used to match particular DHCP scopes. ■ Health policy A statement of health compliance or noncompliance according to a particular SHV ■ SHV A software component that performs a particular set of tests about the safety of a client connection ■ Windows SHV The default SHV and only SHV built into Windows Server 2012
Figure 7-2 illustrates how these components could work together in a particular example of NAP processing.
The procedures for configuring the various NAP enforcement types all differ from each other, but they do share common steps. In general, you first configure the NAP server by using the NAP Configuration Wizard. You use this wizard to specify the NAP enforcement type you want to implement and to create the required connection request policies, network policies, and health policies. After running the wizard, you create security groups for NAP and configure Group Policy. For more information about implementing the various NAP enforcement types, visit http://technet.microsoft.com/en-us/library/dd314175(v=ws.10).aspx.
Windows Server 2008 allowed you to configure just one set of health tests for each SHV. As a result, an NPS server couldn’t typically adjust its health checks to suit different NAP client types.
This limitation could sometimes present a problem. In some scenarios, you might prefer to apply different health checks to different enforcement methods, computers, or users. For example, you might want to require all VPN-connected computers to have their antivirus software both enabled and up to date but require local DHCP-based connections to have their antivirus software enabled only. To meet such a requirement in Windows Server 2008, you usually needed to use two NPS servers.
In Windows Server 2008 R2 and Windows Server 2012, however, you can create multiple configurations for each SHV. After you create configurations in addition to the default configuration, you can specify which SHV configuration you want to use for a particular health policy. Figure 7-3 shows an example of multiple configurations created for the built-in SHV, Windows Security Health Validator.
In Windows Server 2008 R2 and Windows Server 2012, a Settings node appears in the Network Policy Server console beneath the default Windows Security Health Validator (and beneath any additional SHVs you have installed that are also compatible with multiple configurations). When you select the Settings node, only the Default Configuration appears by default. This configuration can’t be deleted or renamed.
Creating additional SHV configurations
To create an additional confi guration for an SHV, perform the following steps. (These steps demonstrate the procedure using the built-in Windows Security Health Validator as the SHV.)
1. In the Network Policy Server console tree, navigate to Network Access Protection \System Health Validators\Windows Security Health Validator\Settings. 2. Right-click Settings and then click New, as shown in Figure 7-4.
3. In the Configuration Friendly Name dialog box, type a name for the new configuration, and then click OK. 4. In the Windows Security Health Validator window, shown in Figure 7-5, specify the desired system health requirements for the configuration.
You can enable any of the following health checks: ■ A Firewall Is Enabled For All Network Connections If this check box is selected, the client computer must have a firewall that is registered with Windows Security Center and enabled for all network connections. ■ An Antivirus Application Is On If this check box is selected, the client computer must have an antivirus application installed, registered with Windows Security Center, and turned on. ■ Antivirus Is Up To Date If this check box is selected, the client computer can also be checked to ensure that the antivirus signature fi le is up to date. ■ An Antispyware Application Is On If this check box is selected, the client computer must have an antispyware application installed, registered with Windows Security Center, and turned on. ■ Antispyware Is Up To Date If this check box is selected, the client computer can also be checked to ensure that the antispyware signature fi le is up to date. ■ Automatic Updating Is Enabled If this check box is selected, the client computer must be configured to check for updates from Windows Update. You can choose whether to download and install them. ■ Security Update Settings Use this section to define health checks related to security updates. If you select the option to restrict access for clients that do not have all available security updates installed, clients will be designated as noncompliant if they do not meet this requirement according to the criteria you specify. You can specify the minimum severity level required for the updates and the minimum number of hours allowed since the client has checked for security updates. You can also require clients to use Windows Server Update Services (WSUS), Windows Update, or both sources.
Unluckily from here and learning.microsoft.com Training Catalog Book Details, it is very unclear if printed book also includes a CD with ebook version in .PDF format just like I've found in many other Microsoft Press books.
Cold you please better clarify on this ?
I'm asking here because at least one of your online resellers do seem to be able to sell printed and electronic versions together but here it's unclear if an official ebook version really exists.
Roberto, this print book does not come with an ebook, but you can purchase an ebook bundle here: shop.oreilly.com/.../0790145369666.do
