SQL Server 2008 introduces a feature called Transparent Data Encryption (TDE), which we ll discuss later in this chapter. When enabled, TDE automatically encrypts and decrypts data as it s read from and written to the database without the need for any application changes. Even with TDE enabled, other than the initial login credentials, the network transmission of data is unencrypted, meaning packet sniffers could be used to intercept data. For maximum data security, the network transmission of SQL Server data can be encrypted using either Internet Protocol Security (IPSec) or Secure Sockets Layer (SSL). Requiring no SQL Server configuration, IPSec encryption is configured at the operating system level on both the SQL Server and the connecting clients. SSL encryption can be enabled using a combination of an installed certificate and the SQL Server Configuration Manager tool. SQL Server can use either self-signed or public certification authority certificates. As mentioned earlier in this chapter, self-signed certificates offer only limited security

and are susceptible to man-in the-middle attacks. For maximum SSL security, certificates from a public authority such as VeriSign can be used. Once you ve installed a certificate, you can use the SQL Server Configuration Manager tool to configure a SQL Server instance to use the certificate and to specify whether or not client connections are accepted that can t support an encrypted connection. In a similar manner, Configuration Manager lets you configure the client end of the connection, with the option to force encryption, and whether or not to trust a server with only a self-signed certificate. SQL Server BOL contains a full description of the process for enabling SSL encryption for a SQL Server instance, including coverage of cluster-specific encryption processes. In addition to BOL, you ll find a number of links to articles containing step-bystep encryption setup instructions at the book s companion website, available at http://www.sqlcrunch.com/security. As with any encryption, SQL Server network encryption involves processing overhead and therefore lowers performance to some degree. In environments with sensitive data, the performance impact of encryption is typically of less concern than protecting the data from unauthorized access. Before implementing encryption in a production environment, test and measure the process and overhead in a test environment. Even with strong network security and authentication models in place, a SQL Server instance is far from secure if those with legitimate access to a SQL Server instance have more access than what they actually need. With a significant percentage of security breaches performed as inside jobs, the importance of least privilege is not to be underestimated.

Note that even for classic OLTP applications such as point-of-sales systems, actions like backups and database consistency checks will still generate large amounts of sequential I/O. For the purposes of I/O workload classification, we ll consider the main I/O pattern only. As you ll see a little later, the difference between sequential and random I/O has an important bearing on the storage system design.

Information managers use consulting services widely to stay competitive in an environment of constantly changing technology Large companies spend millions on consulting and research services As companies grow, shrink, restructure, begin global operations, and change technology, they employ consultants to help with these transitions Such tasks as selecting equipment and software to meet both current and future needs, setting up massive computer and communications systems, and reengineering the company organization and work procedures to implement the new technology are often beyond the abilities of in-house staff The risk is so great and the cost is so large that managers look to experts to help them make the right decisions Contract programming, disaster recovery, and systems integration are among services provided by outsiders such as information or professional services firms, consultants, and contract programmers This trend is likely to continue In good humor, consultants have been defined as professionals who have been out of work for more than two months And regarding their work, it is said that consultants borrow your watch then tell you what time it is Humor aside, consultants provide a valuable service in a constantly changing field Consultants in information fields may work for themselves as individual freelance specialists; for small firms with staffs of specialists; for large firms, such as Deloitte & Touche, Complete Business Solutions, Inc, and Stopka & Associates; or for any type of organization or industry as an internal consultant Because of increasing security problems, companies turn to security consulting firms such as Rent-A-Hacker, IBM s Ethical Hacking Service, Pinkerton s Information Risk Group, and Counterpane Internet Security
