Network Access Protection NAP is a Microsoft technology for controlling network access of a computer, based on its health. With NAP, system administrators of an organization can define policies for system health requirements.

Network Access Protection NAP is a system designed to protect networks from clients which are not deemed to be secure or healthy to use Microsoft's terminology. When NAP is implemented, clients without the required level of "health" are directed to a remediation server where the necessary updates may be obtained to bring the system into compliance with the Network Access policy of the network. In addition, the user may also be directed to a web page providing details of why access to the network has been declined and outlining the steps necessary to remedy the problem.

Today's security challenges come both from the changing threat environment but also from changes in how we work. Mobile working is now the norm rather the exception. Many employees use their company laptops for both business and personal use. While this is a boon to productivity and work-life balance, it also means we are in danger of losing control of corporate IT assets. Traditional security solutions, such as firewalls, anti-virus, anti-spyware, patch management, or VPNs are no longer sufficient to keep the threats off the network.

While these play a vital role, companies are still dealing with devices connecting to the network with unpatched software, out-of-date anti-virus and improper security settings. Not keeping devices up to date is probably the largest hole in the security fight today. Network access control NAC products entered the market a few years ago to fill this gap. A typical NAC solution provides an endpoint assessment of the computer and then enables access and enforces security policy based on the state of the computer and the identity of the user.

Early NAC solutions were expensive and complex and targeted at the large enterprise market. But even for those companies with budgets and IT staff to manage NAC, the deployments often failed or stalled. This was due to complexity, the lack of interoperability and proprietary technologies used in the NAC solutions. Cisco, Microsoft, and the Trusted Computing Group TCG , a consortium of suppliers, proposed alternate frameworks and interoperable architectures in an attempt to overcome this hurdle.

Today, NAC is moving toward more standards-based protocols. Under NAP Microsoft is interoperating with other vendor solutions, and encouraging partners to develop agents and tools to enable NAP to communicate with non-Windows devices as well as competing policy servers. Most of the anti-virus products work with NAP, and hopefully all of them will.

If you are a smaller organisation, then you don't need Windows Server but can use a network appliance to enforce policies and directly communicate with the Microsoft NAP agent. If you have Macintosh or Linux computers, then you need to look for cross-platform support. There is much debate about where to enforce NAC, but I believe that the best place is at the network layer layer 2 or 3. There are now several NAC appliances that are relatively easy to deploy and manage.

Also, it's best to find a solution that provides centralised management for both employee and guest accesses. Mobile employees pose a huge risk to your network, but visitors, partners or suppliers working on site bring an even greater danger, since you have no way to manage those devices.

A good NAC solution should enable you to provide guests with controlled and safe access either to the internet or a select group of printers or network resources, without exposing the rest of the network. It is useful to be able to implement NAC in phases, so you aren't disrupting your network or your workers or creating a burden for your help desk.

Your first task is to monitor your environment. Gather the information you need and understand what is actually happening with devices on your network. Many IT managers are shocked by what they find. One IT manager discovered he had several virtual machines on his network he was unaware of another found that more than half of the laptop computers were not running the latest security patches yet another found their desktop security suite was incorrectly configured and that all of their desktop firewalls were disabled.

This insight into your network is one of the greatest benefits of NAC. While few companies deploy NAC for this reason, it is always the first thing IT staff notice and appreciate. Never before have they been able to have this central view of every device on the network and, importantly, the security status of those devices. In spite of your efforts, employees often ignore the rules. Even with NAC, you need to think about authentication of both devices and users.

For example, many companies are now using Wi-Fi access points to provide easy wireless access to the corporate network, but they forget to add the necessary security.

But in our recent survey of 40 small and medium enterprises, more than half used a shared password for all wireless access. Regardless of your choice of encryption, this is an obvious Achilles heel because individual users cannot easily be identified and any change to the shared password creates massive disruption. Identifying wireless users and dealing with changing a shared password regularly is one task that makes wireless access a management nightmare.

This requires every user to authenticate with his or her own username and password when connecting. Although initial setup of WPA Enterprise can be difficult, the day-to-day burden of changing a shared password is eliminated.

WPA Enterprise also means you can give guests access by creating a guest user. I have yet to meet an organisation that didn't have at least one computer on their network that was out of compliance or that presented a direct threat to the network.

No matter what they have, if they don't have a way to check devices before they access the network, they risk having a virus or other threat spread across the company. While you may not be able to control everything your employees do, you can take control back of mobile computing and implement better policies and technologies that make sure all devices accessing the network are healthy and secure.

To enable Internet Connection Sharing, follow these steps: 1. Click Start, right-click Network, and then click Properties. In the Tasks pane, click Manage Network Connections. In the Network Connections window, right-click the interface with the public IPv4 address, and then click Properties. Click the Home Networking Connection list, and select the network adapter associated with the private network. Click OK.

The client-server protocol is used for user and computer authentication, authorization, and accounting. RADIUS is often used in combination with access points, VPNs, and other technologies in which the protocol controls the dial-in or login to a computer network. During authentication, the service determines which user or computer wants to authenticate itself. To make sure the user or computer is who or what they claim to be, classic username and password procedures are used along with security tokens. Once the resource is uniquely identified, authorization takes over the assignment of rights and permissions. Accounting account management here refers to logging by the network policy server.
