Hardening is the process of protecting a system against unknown threats. System administrators harden against that which they
think
could be a threat. Administrators know the Internet is a hostile environment. Although they can't tell, for example, that a hacker will attempt to gain access to the SQL server next Tuesday, they can bet money there'll be an attempt soon and should "batten down the hatches" in anticipation.
Hardening Windows, Second Edition
is the definitive "counterintelligence" guide to performing preventative security measures for the Windows operating system.
