| Abstract | Access control mechanisms (ACM) play a critical role in protecting operating systems from malicious attacks. A variety of ACMs have been proposed till date, including discretionary access control (DAC) and mandatory access control (MAC). However, it is often challenging to evaluate and compare the quality of protection (QoP) of ACMs, especially when they are deployed on different platforms. In this paper, we propose an approach to quantitatively measure and compare the quality of ACMs. We introduce the notion of vulnerability profiles to capture the weakness of ACMs in protecting against attacks, and the notion of vulnerability coefficients as a numeric and platform-independent measurement of the protection quality of ACMs. Based on these two notions, our approach applies the Grey System Theory and an independent vulnerability scoring system to infer complete vulnerability profiles and to calculate fair and objective vulnerability coefficients for ACMs. To our knowledge, our approach is the first attempt for quantitative measurement and comparison of ACMs across different operating systems. Based on our approach, we implement a prototype tool called ACVAL that leverages logic programming to characterize, evaluate, and compare access control mechanisms. We apply ACVAL to three mainstream ACMs, and results that ACVAL is effective in evaluating access control mechanisms across different operating systems, a feature particularly useful to administrators of heterogenous IT systems. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
