Security
The Windows Security Center, which encompasses both security and maintenance of the computer, has been renamed Windows Action Center (Windows Health Center and Windows Solution Center in earlier builds).
A new user interface for User Account Control has been introduced, which provides the ability to select four different levels of notifications, one of these notification settings, Default, is new to Windows 7. Geo-tracking capabilities are also available in Windows 7. The feature will be disabled by default. When enabled the user will only have limited control as to which applications can track their location.
The Encrypting File System supports Elliptic-curve cryptographic algorithms (ECC) in Windows 7. For backward compatibility with previous releases of Windows, Windows 7 supports a mixed-mode operation of ECC and RSA algorithms. EFS self-signed certificates, when using ECC, will use 256-bit key by default. EFS can be configured to use 1K/2k/4k/8k/16k-bit keys when using self-signed RSA certificates, or 256/384/512-bit keys when using ECC certificates.
In Windows Vista, the Protected User-Mode Audio (PUMA) content protection facilities are only available to applications that are running in a Protected Media Path environment. Because only the Media Foundation application programming interface could interact with this environment, a media player application had to be designed to use Media Foundation. In Windows 7, this restriction is lifted. PUMA also incorporates stricter enforcement of "Copy Never" bits when using Serial Copy Management System (SCMS) copy protection over an S/PDIF connection, as well as with High-bandwidth Digital Content Protection (HDCP) over HDMI connections.

Famous quotes containing the word security:
“The three great ends which a statesman ought to propose to himself in the government of a nation, are,—1. Security to possessors; 2. Facility to acquirers; and, 3. Hope to all.”
—Samuel Taylor Coleridge (1772–1834)
“Thanks to recent trends in the theory of knowledge, history is now better aware of its own worth and unassailability than it formerly was. It is precisely in its inexact character, in the fact that it can never be normative and does not have to be, that its security lies.”
—Johan Huizinga (1872–1945)
“There is something that Governments care for far more than human life, and that is the security of property, and so it is through property that we shall strike the enemy.... Be militant each in your own way.... I incite this meeting to rebellion.”
—Emmeline Pankhurst (1858–1928)
