Public key encryption uses two keys, a public key and a private key. Data encrypted with the public key can only be decrypted using the private key, and data encrypted using the private key can only be decrypted with the public key. A public key infrastructure is a collection of software components and operational policies that govern the distribution and use of public and private keys. Certificates are issued by a certification authority (CA). You can run your own CA using Windows Server 2003, or you can obtain your certificates from a third-party commercial CA. The first step in planning a PKI is to study what the security enhancements certif icates can provide and determine which of your organization s security require ments you can satisfy with certificates. When running multiple CAs in an enterprise, you configure them in a hierarchy, with a root CA at the top, intermediate CAs at the second level, and subordinate (or issuing) CAs at the bottom. The configuration parameters of certificates themselves include the certificate type, the encryption algorithm and key length the certificates use, the certificate s lifetime, and the renewal policies that dictate how the CA behaves when process ing certificate renewal requests. Only enterprise CAs can use auto-enrollment, in which clients send certificate requests to a CA and the CA automatically issues or denies the certificate. For a client to receive certificates using auto-enrollment, it must have permission to use the certificate template for the type of certificate it is requesting. Stand-alone CAs do not use certificates or autoenrollment. Certificate requests are stored in a queue on the CA until an administrator approves or denies them. CAs publish certificate revocation lists (CRLs) at regular intervals, to inform authenticating computers of certificates that they should no longer honor.

Before taking the exam, review the key points and terms that are presented next to help you identify topics you need to review. Return to the lessons for additional practice, and review the Further Reading sections in Part 2 for pointers to more information about topics covering the exam objectives.
Key Points
In an Active Directory environment, you should create enterprise (as opposed to stand-alone) CAs. Enterprise CAs support auto-enrollment and use certificate tem plates and Active Directory object information to automatically issue certificates to clients. Certificate Services is a Windows Server 2003 service that enables administrators to configure, issue, and revoke digital certificates for specific security functions, such as secure e-mail, EFS, IPSec, Internet server authentication, and smart card logons. Windows Server 2003 Certificate Services supports two basic types of certification authorities: enterprise and stand-alone. Enterprise CAs are intended for internal clients and store their information in Active Directory. Stand-alone CAs are intended for external clients, and store their information in a database file. Clients can obtain certificates in three ways: through autoenrollment, by using the Certificates snap-in, and by using the Web Enrollment Support interface. A smart card is a portable device that contains a user s certificate and private key, enabling the user to log on to the network from any workstation equipped with the appropriate hardware. Support for smart card logons is provided only by enterprise CAs, in conjunction with Active Directory.
Key Terms
Public key encryption A security system in which each user has two encryption keys, a public key and a private key. Data encrypted using the public key can only be decrypted by the private key and data encrypted using the private key can only be decrypted using the public key. Hash A digital summary of a message created by removing redundant bits according to a specialized hashing algorithm. Hashes are used to digitally sign messages and to confirm that messages have not been tampered with in transmission. Delta CRL A list containing only the certificates that have been revoked since the last certificate revocation list was published. Using delta CRLs instead of base CRLs (which contain the entire list of all revoked certificates) can save network bandwidth.
