An Access Control Architecture for Context-Risk-Aware Access Control: Architectural Design and Performance Evaluation

2010 Fourth International Conference on Emerging Security Information, Systems and Technologies, 2010
Risk assessment plays a significant role in Decision Support Systems (DSS). Recently, there have been efforts to exploit the potential of linking risk assessment to security provisioning to provide risk-aware security services. One of these efforts is the Context-Risk-Aware Access Control (CRAAC) model that links requesters' access privileges to the ...

Architecture of Future Access Networks

2008
A key issue to reach a highly scalable Passive Optical Network (PON) with very high splitting ratio is the high multiplexing level required to handle all individual signals (individual data flows) that travel along shared fibres. The available fibre bandwidth and current high-speed electronics allow high splitting ratios together with high bandwidth ...

Integrated Narrowband/Broadband Access Architecture

SMPTE Journal, 1995
Southwestern Bell Telephone (SWBT) Technology Planning chose a digital fiber-optic, integrated narrowband/broadband fiber-to-the-curb (FTTC) access architecture for deployment in the Richardson, Texas, video trial. The trial architecture consists of a two-level network: Level 1 and Level 2.

Next Generation Access – Architecture Challenges

Asia Communications and Photonics Conference and Exhibition, 2009
Today's available fibre access technologies are based on point-to-point, GPON, EPON or active node solutions. This paper will focus on challenges in future access networks from an architectural, technological and economical point of view.

An access control reference architecture

Proceedings of the 2nd ACM workshop on Computer security architectures, 2008
System administrators typically have unrestricted access to all files and programs on a system, with no enforced principle of least privilege. Additionally, this unrestricted access causes challenges for audit as many different users might have superuser access and the audit trail may not distinguish between the actual users, recording instead all ...

Intelligent Access Program: System architecture

2009 IEEE Intelligent Vehicles Symposium, 2009
The Intelligent Access Program (IAP) provides heavy vehicles with improved access to the Australian road network by utilization of GPS technology to remotely monitor heavy vehicles against access conditions imposed on them by Jurisdictions. The paper provides a background to this program and describes the IAP system architecture including data flow ...

The architecture of global access

IEEE Internet Computing, 1997
The Internet is about access-on the simplest level, access to data, to information and to knowledge; on a more complex level, access to the processing of knowledge; and on the most complex level, access to individuals, to organizations and to government. This article thus describes the architecture of information access.

Flexible Access System Architecture (FASA)

Optical Fiber Communication Conference, 2018
To quickly meet diverse requirements given by emerging new services, we recently proposed a new concept of Flexible Access System Architecture (FASA). The paper reviews our activities on FASA along with disaggregation of time-critical functions.

Architecture for Personal Web Accessibility

2006
Universal web accessibility is an inalienable objective to guarantee the civil right of all users to access to the Information Society and to avoid the digital gap. This is a long process based on the promulgation of inclusive laws, specification of accessibility guidelines, and development of adequate design methodologies and tools. To the short term,
