Wang, Qihua. Ph.D., Purdue University, May 2009. Access Control Policy Management. Major Professor: Ninghui Li. Access control is the traditional center of gravity of computer security [1]. People specify access control policies to control accesses to resources in computer systems. The management of access control policies include policy specification and policy analysis. In this dissertation, ...

Access control service is used to solve the controllability problem of data and service, access control system is finally deployed in the form of policy. The description forms of policy are different in the stage of configuration and deployment. Safety policy translation model is used to realize configuration policy and automatic translation of deployment policy. However, currently it lacks aut...

Personal location data is stored as the result of using equipment that many people now own or have access to. Typically this data contains details of identity, location and the time the equipment was used. The data is usually stored in a central repository, held by the organisation owning the network or related equipment, and it is assumed that access controls are in place and privacy policies ...

In this study we investigate the quality of the selection process of an open access (OA) journal, taking as an example the journal Atmospheric Chemistry and Physics (ACP). ACP is working with a new system of public peer review. We examined the predictive validity of the ACP peer review system – namely, whether the process selects the best of the manuscripts submitted. We have data for 1111 manu...

SIVASUBRAMANIAN, DHIVYA. Automated Access Control Policy Testing Through Code Generation. (Under the direction of Ting Yu.) Any multiuser system has to enforce access control for protecting its resources from unauthorized access or damage. One way for specifying access control is in a separate policy specification language. An access control system maintains a repository of policies, receives a...

Review comments on “How to improve the air quality over mega-cities in China? – Pollution characterization and source analysis in Shanghai before, during, and after the 2010 World Expo” by Huang et al. This manuscript provides an important study on the PM2.5 pollution in Shanghai before, during, and after the 2010 World Expo. The topic is applicable for Atmospheric Chemistry and Physics; howeve...

This manuscript presents an intercomparison exercise of tropospheric HCHO retrieved from satellites measurements using several products obtained from independent retrieval approaches. In order to validate the products, the authors use aircraft observations during the short term field deployment of SEAC4RS in the Southeast of the US. This is an important validation effort. In general, the paper ...

As one of the most fundamental security mechanisms of resources, Access Control Policies (ACP) specify which principals such as users or processes have access to which resources. Ensuring the correct specification and enforcement of ACPs is crucial to prevent security vulnerabilities. However, in practice, ACPs are commonly written in Natural Language (NL) and buried in large documents such as ...
