This article presents the mechanisms in Windows 2000 that enable fine-grained and centrally managed access control for both operating system components and applications. These features were added during the transition from Windows NT 4.0 to support the Active Directory, a new feature in Windows 2000, and to protect computers connected to the Internet. While(More)
This paper presents the access control mechanisms in Windows 2000 that enable fine-grained protection and centralized management. These mechanisms were added during the transition from Windows NT 4.0 to support the Active Directory, a new feature in Windows 2000. We first extended entries in access control lists to allow rights to apply to just a portion of(More)
The Secret Key Transaction Authentication for DNS (TSIG) protocol provides transaction level authentication for DNS. TSIG is extensible through the definition of new algorithms. This document specifies an algorithm based on the Generic Security Service Application Program Interface (GSS-API) (RFC2743). This document updates RFC 2845. Kwan, et al. Standards(More)
Access control is acknowledged to be one of the most important aspects of security. Research and deployments related to access control in computers and networks dates back several decades. Nevertheless, several aspects of access control remain challenging in practice. This panel pulls together four experts from industry that have dealt with access control(More)
Many security breaches are caused by inappropriate inputs crafted by people with malicious intents. To enhance the system security, we need either to ensure that inappropriate inputs are filtered out by the program, or to ensure that only trusted people can access those inputs. In the second approach, we sure do not want to put such constraint on every(More)
