8. The packet SPI is used to find the corresponding SA. This step is necessary because multiple SAs might exist and only the corresponding SA has the associated cryptographic key necessary to decrypt and process the packets. 9. Computer Two s IPSec driver uses the inbound SA to retrieve the keys and processes the packets. 10. The IPSec driver converts the packets back to normal IP packet format and passes them to the TCP/IP driver that passes them to the receiving application. 11. Quick Mode IPSec SAs continue processing packets. SAs are refreshed until they are no longer needed, and then they are deleted. IKE Negotiation Mode SAs are not deleted when idle. By default, they have a lifetime of 8 hours. Their lifetime can be configured to a minimum of 5 minutes and a maximum of 48 hours. New traffic will trigger a new Quick Mode negotiation.

To share the folder, follow these steps: Right-click the folder, then click Properties. In the Properties dialog box for the folder, select the Sharing tab. Click Share This Folder and ensure that the shared folder name appears in the Share Name box. Click OK.

Follow these guidelines when designing IPSec policies:

3. Open the folder and create a subfolder to store the mandatory user profile. Ensure that the subfolder can be easily identified as the folder containing the mandatory user profile. Defining a Mandatory User Profile You define a mandatory user profile by selecting the profile template, specifying the path to the folder you created to store the manda tory user profile, and selecting the user or group you want to be able to use the man datory user profile in the User Profiles tab in the System Properties dialog box. To define a mandatory user profile, complete the following steps: 1. Locate the System Properties dialog box with the User Profiles tab that you left open when creating the mandatory user profile template. 2. In the User Profiles dialog box, shown previously in Figure 7-10, select the user whose profile you want to use as the mandatory user profile, then click Copy To. The user account should be the same one you created for the mandatory user profile template in the previous procedure. 3. In the Copy To dialog box, shown in Figure 7-11, type the path to the folder you created to store the mandatory user profile in step 1, using the format \\Server_name\Shared_folder_name. In the Permitted To Use box, click Change.

Use network cards that support encryption on servers. If a server must manage many connections and encrypt all data, the performance of that server might deteriorate. There are several network cards that can offload IPSec encryp tion to a built-in processor on the network card. Windows IPSec is designed to use these cards if they are present. Do not encrypt traffic between domain controllers and their clients. To authenticate, the client must connect to the server. To do so requires the establish ment of an IPSec connection. However, IPSec cannot be negotiated because it requires authentication. Ensure that the protocols that are required are configured. Several proto cols were originally excluded from the Windows implementation of IPSec. Most of these are no longer excluded. For every protocol that must be used in a commu nication, you must configure a filter. Design a single policy for each computer. Only one policy at a time can be assigned to a computer. A policy can have multiple filters and multiple rules. By using multiple rules and filters, a policy can be designed for most circumstances. Select multiple choices for encryption, integrity algorithm, Diffie-Hellman group, and authentication process in a policy when this is necessary for communication with many different Windows clients. Part of the negotiation process is selecting a combination that both IPSec peers (two computers that consummate a successful negotiation) can use. Different Windows computers might not be capable of all possible selections, so you must provide those they can work with. Narrow the
