Forefront Security for Office Communications Server provides layered protection for OCS 2007 Enterprise Edition (and OCS 2007 R2), integrating with Access Edge, Director and Front-end server roles for enterprise-wide security. The integration with the Access Edge role allows Forefront Security for Office Communications Server to protect federated and public IM connections as well as remote users, which we’ll talk about in detail in our next slide.
Title: Using Network Access Protection Talking Points: Let’s look in more depth in how Network Access Protection works. Network Access Protection works with agents in the Windows XP SP2 or Windows Vista client operating systems. The client environment includes the System Health Agents (SHAs), a Quarantine Agent (QA) and an Enforcement Client (EC). The Secure Hash Algorithm (SHA) checks the state of a client and declares its health. Each SHA is defined for a system health requirement or a set of system health requirements. For example, there might be an SHA for antivirus signatures and an SHA for operating system updates. [BUILD1] Try to Connect to a Network: When a Windows client computer connects though DHCP, a VPN, or a router, the system health validators state what the computer’s health is. [BUILD2] System Health Agent: The access device then forwards the network access request on to the NPS.The NPS includes the System Health Validator (SHV) and the Quarantine Server (QS). The QS coordinates the SHVs which certify declarations made by health agents.Active Directory stores user and computer accounts and their network access properties for authenticated network access. The NPS itself does not make the authentication decision, but evaluates the connection and then forwards the credentials on to Active Directory.[BUILD3] Remediation Server: If a computer is not compliant, it is sent to a restricted network, where the remediation servers can apply security updates or whatever else is needed to enable compliance. Remediation servers consist of servers, services, or other resources that a noncompliant computer on the restricted network can access. These resources might store the most recent software updates or components needed to make the computer comply with health requirements. For example, a secondary DNS server, an antivirus signature file server, and a software update server could all be remediation servers. [BUILD4] Computer that meets Health Policy: If a client is compliant, then the system is given access to the corporate network.

The primary components of the NAP solution consist of the following: NAP Client System Health Agents and System Health ValidatorsComponents of the NAP infrastructure known as system health agents (SHAs) and system health validators (SHVs) provide health state tracking and validation. Windows Vista and Windows XP Service Pack 3 include a Windows Security Health Validator SHA that monitors the settings of the Windows Security Center. Windows Server 2008 includes a corresponding Windows Security Health Validator SHV. NAP is designed to be flexible and extensible. It can interoperate with any vendor’s software that provides SHAs and SHVs that use the NAP API. Enforcement Components and MethodsComponents of the NAP infrastructure known as enforcement clients (ECs) and enforcement servers (ESs) require health state validation and enforce limited network access for noncompliant computers for specific types of network access or communication. Windows Vista, Windows XP Service Pack 3, and Windows Server 2008 include NAP support for the following types of network access or communication:Internet Protocol security (IPsec)-protected trafficIEEE 802.1X-authenticated network connectionsRemote access VPN connectionsDynamic Host Configuration Protocol (DHCP) address configurationsWindows Vista and Windows Server 2008 also include NAP support for Terminal Server (TS) Gateway connections.These types of network access or communication are known as NAP enforcement methods. Administrators can use them separately or together to limit the access or communication of noncompliant computers. Network Policy Server (NPS) in Windows Server 2008, the replacement for Internet Authentication Service (IAS) in Windows Server 2003, acts as a health policy server for all of these NAP enforcement methods. System Health Servers Also known as, Health Registration Authorities, provide current system health state for NAP health policy servers. For example, a health requirement server for an antivirus program tracks the latest version of the antivirus signature file. NPSNPS is a Remote Authentication Dial-In User Service (RADIUS) server and proxy in Windows Server 2008. As a RADIUS server, NPS provides authentication, authorization, and accounting (AAA) services for various types of network access. For authentication and authorization, NPS uses Active Directory to verify user or computer credentials and obtain user or computer account properties when a computer attempts an 802.1X-authenticated connection or a VPN connection. NPS also acts as a NAP health policy server. Administrators define system health requirements in the form of health policies on the NPS server. NPS servers evaluate health state information provided by NAP clients to determine health compliance, and for non-compliance, the set of remediation actions that must be done by the NAP client to become compliant. Remediation serversComputers that contain health update resources that NAP clients can access to remediate their noncompliant state. Examples include antivirus signature distribution servers and software update servers.

What is Microsoft NAP?An extensible compliance definition, validation, remediation and reporting frameworkthat can limit access if required Compliance Definition Define custom health policies (collections of “compliance checks”) that are relevant to the definition of machine “compliance”. Validation NAP assesses the compliance state of machines against an administrator-defined health compliance policy. Validation triggers: resource access attempt, periodic time-basis, client-side compliance check state monitoring. Remediation NAP can drive machines to automatically “remediate” or correct their compliance deviations, often without user-intervention. Reporting NAP stores compliance state and context data from the NAP framework and NAP extensions in a common database for analysis, reporting and other purposes. Access Control Machine compliance state, as evaluated by NAP, can be used to limit access to various resources. Extensible Framework The NAP framework is extensible - enabling MS and 3rd parties to extend compliance checks, remediation, compliance data transport/access control technologies and non-MS NAP clients.
Remediation Servers Example: Patch Restricted Network Corporate Network Using Network Access Protection Security Policy Servers such as: Patch, AV 3 1 2 Not policy compliant 4 DHCP, VPN Switch/Router Windows Client NPS Policy compliant 5 If not policy compliant, client is put in a restricted VLAN and given access to fix up resources to download patches, configurations, signatures (Repeat 1 - 4) DHCP, VPN or Switch/Router relays health status to Microsoft Network Policy Server (RADIUS) Network Policy Server (NPS) validates against IT-defined health policy If policy compliant, client is granted full access to corporate network Client requests access to network and presents current health state 2 3 4 5 1
