Windows 2000 ipsec policy

Deb is a tech editor, developmental editor, and contributor to over 20 add With almost every computer networked, at least on a part-time basis, a special concern is how to secure data as it travels across that network. When an individual machine or local network is connected to the Internet, security becomes even more crucial.

Disk encryption protects files from the prying eyes of another who logs on to the local computer, but what happens if you send a file across the network after encrypting it on the disk? Exchanging sensitive information across a network, especially a public network, requires a security method that will protect the data in transit. IPSec is a set of protocols that allows you to sign and encrypt data to be sent across an IP network, and authenticate and decrypt the protected packets on the receiving end.

What is IPSec? IPSec is a set of protocols and cryptography-based services that work together to protect data from unauthorized access or tampering when it is sent across an IP network. IPSec security protocols IPSec uses two protocols to accomplish these tasks: Authentication Header AH : This signs the entire packet, providing authentication and ensuring integrity of the data.

AuthIP in Windows Vista. An IPsec policy is a set of rules that determine which type of IP traffic needs to be secured using IPsec and how to secure that traffic.

Only one IPsec policy is active on a computer at one time. IPsec policies are implemented by adding filters at various WFP layers as follows. Authentication methods and cryptographic algorithms are specified at these layers.

A negotiation policy is specified as a policy provider context associated with the filter. The keying module enumerates the policy provider contexts based on the traffic characteristics and obtains the policy to use for the security negotiation. The following diagram illustrates the interaction of the various WFP components, with respect to IPsec operation.

Enable the Client respond-only policy on the Terminal Services clients. Click Close , and then click Close. Click Apply , and then click OK. Right-click the new policy, and then click Assign.

But since we have a large number of Windows and servers I was wondering how these would be handled.

I know there is no NAP client for Windows and but can I set up IPsec Enforcement so that only complient machines are able to communicate with these servers? The set of computers that do not have health certificates.
