access control is one of key aspects of computer security. Current access control models do not take into account the context of the system and its environment. In this paper, we present a particular context model for the access control system primarily-intended for business processes access control. By using a context-sensitive access control, it is possible to define more sophisticated access control policies that cannot be implemented by existing access control models. the proposed context is modeled using Web Ontology Language (OWL) in order to provide: formal representation of context, rich representation of different contextual information, semantic interoperability between different context-aware systems and high degree of inference making. © 2012 IEEE.

Algorithms for mining meaningful roles 12

Role-based access control (RBAC) offers significant advantages over lower-level access control policy representations, such as access control lists (ACLs). However, the effort required for a large organization to migrate from ACLs to RBAC can be a significant obstacle to adoption of RBAC. Role mining algorithms partially automate the construction of an RBAC policy from an ACL policy and possibly other information, such as user attributes. these algorithms can significantly reduce the cost of migration to RBAC. this paper proposes new algorithms for role mining. the algorithms can easily be used to optimize a variety of policy quality metrics, including metrics based on policy size, metrics based on interpretability of the roles with respect to user attribute data, and compound metrics that consider size and interpretability. the algorithms all begin with a phase that constructs a set of candidate roles. We consider two strategies for the second phase: start with an empty policy and repeatedly add candidate roles, or start with the entire set of candidate roles and repeatedly remove roles. In experiments with publicly available access control policies, we find that the elimination approach produces better results, and that, for a policy quality metric that reflects size and interpretability, our elimination algorithm achieves significantly better results than previous work.

Role based access control (RBAC) is the de facto model used for advanced access control due to its inherent richness and flexibility. Despite its great success at modeling a variety of organizational needs, maintaining large complex policies is a challenging problem. Conflicts within policies can expose the underlying system to numerous vulnerabilities and security risks. therefore, more comprehensive verification tools for RBAC need to be developed to enable effective access control. In this paper, we propose a verification framework for detection and resolution of inconsistencies and conflicts in policies modeled through event-driven RBAC, an important subset of generalized temporal RBAC applicable to many domains, such as SCADA systems. We define the conflict resolution problem and propose an integer programming based heuristic. the proposed approach is generic and can be tuned to a variety of optimality measures.

We introduce two approaches for improving privacy policy management in online social networks. First, we introduce a mechanism using proven clustering techniques that assists users in grouping their friends for group based policy management approaches. Second, we introduce a policy management approach that leverages a user's memory and opinion of their friends to set policies for other similar friends. We refer to this new approach as Same-As Policy Management. To demonstrate the effectiveness of our policy management improvements, we implemented a prototype Facebook application and conducted an extensive user study. Leveraging proven clustering techniques, we demonstrated a 23% reduction in friend grouping time. In addition, we demonstrated considerable reductions in policy authoring time using Same-As Policy Management over traditional group based policy management approaches. Finally, we presented user perceptions of both improvements, which are very encouraging. Copyright 2012 acm.

the immensity and variety of personal information (e.g., profile, photo, and microblog) on social sites require access control policies tailored to individuals' privacy needs. Today such policies are still mainly specified manually by ordinary users, which is usually coarse-grained, tedious, and error-prone. this paper presents the design, implementation, and evaluation of an automated access control policy specification tool, Xaccess, that helps non-expert users effectively specify who should have access to which part of their data. A series of key features distinguish Xaccess from prior work: 1) it adopts a role-based access control model (instead of the conventional rule-based paradigm) to capture the implicit privacy/interest preference of social site users;2) it employs a novel hybrid mining method to extract a set of semantically interpretable, functional "social roles", from both static network structures and dynamic historical activities;3) based on the identified social roles, confidentiality setting of personal data, and (optional and possibly inconsistent) predefined user-permission assignments, it recommends a set of high-quality privacy settings;4) it allows user feedback in every phase of the process to further improve the quality of the suggested privacy policies. A comprehensive experimental evaluation is conducted over real social network and user study data to validate the efficacy of Xaccess. Copyright 2012 acm.

the Resource Description Framework (RDF) has become the defacto standard for representing information in the Semantic Web. Given the increasing amount of sensitive RDF data available on the Web, it becomes increasingly critical to guarantee secure access to this content. In this paper we advocate the use of an abstract access control model to ensure the selective exposure of RDF information. the model is defined by a set of abstract operators and tokens. Tokens are used to label RDF triples with access information. Abstract operators model RDF Schema inference rules and propagation of labels along the RDF Schema (RDFS) class and property hierarchies. In this way, the access label of a triple is a complex expression that involves the labels of the triples and the operators applied to obtain said label. Different applications can then adopt different concrete access policies that encode an assignment of the abstract tokens and operators to concrete (specific) values. Following this approach, changes in the interpretation of abstract tokens and operators can be easily implemented resulting in a very flexible mechanism that allows one to easily experiment with different concrete access policies (defined per context or user). To demonstrate the feasibility of the approach, we implemented our ideas on top of the MonetDB and Post-greSQL open source database systems. We conducted an initial set of experiments which showed that the overhead for using abstract expressions is roughly linear to the number of triples considered;performance is also affected by the characteristics of the dataset, such as the size and depth of class and property hierarchies as well as the considered concrete policy.

Wireless Sensor Networks (WSNs) have attracted a lot of interest in the research community because of their wide range of applications. Due to the distributed nature of WSNs and their deployment in remote areas, these networks are vulnerable to numerous security threats that can adversely affect their proper functioning. access control is a critical security service in WSNs to prevent unauthorised access from the users. Current access control models in WSNs cannot make access control decisions efficiently and effectively when the system faces unexpected and unanticipated events because access control decisions are based on predefined access policies and roles. Sometimes, users may need to access stored data for emergency and immediate data access but the system cannot grant access to this kind of users' request. Based on the needs of real world requirements, we propose an adaptive access control model that builds on the concepts of overriding access privileges and user behaviour monitoring to provide a flexible approach in the access control model. the proposed access control model will adapt to unanticipated events by using privilege overriding and adjust its decision based on users' behaviour. the proposed approach can make an access control model much flexible and also detect abnormal users' request from the authorised users. To the best of our knowledge, the proposed access control model is the first to realize the flexibility of access control model by using the concept of possibility-with-override and users' behaviour monitoring in WSNs.

We consider a fundamentally new approach to role and policy mining: finding RBAC models which reflect the observed usage of entitlements and the attributes of users. Such policies are interpretable, i.e., there is a natural explanation of why a role is assigned to a user and are conservative from a security standpoint since they are based on actual usage. Further, such "generative" models provide many other benefits including reconciliation with policies based on entitlements, detection of provisioning errors, as well as the detection of anomalous behavior. Our contributions include defining the fundamental problem as extensions of the well-known role mining problem, as well as providing several new algorithms based on generative machine learning models. Our algorithms find models which are causally associated with actual usage of entitlements and any arbitrary combination of user attributes when such information is available. this is the most natural process to provision roles, thus addressing a key usability issue with existing role mining algorithms. We have evaluated our approach on a large number of real life data sets, and our algorithms produce good role decompositions as measured by metrics such as coverage, stability, and generality. We compare our algorithms with traditional role mining algorithms by equating usage with entitlement. Results show that our algorithms improve on existing approaches including exact mining, approximate mining, and probabilistic algorithms;the results are more temporally stable than exact mining approaches, and are faster than probabilistic algorithms while removing artificial constraints such as the number of roles assigned to each user. Most importantly, we believe that these roles more accurately capture what users actually do, the essence of a role, which is not captured by traditional methods. Copyright 2012 acm.

Integrated role-based access control (RBAC) and attribute-based access control (ABAC) is emerging as a promising paradigm. this paper proposes a framework that uses attribute based policies to create a more traditional RBAC model. RBAC has been widely used, but has weaknesses: it is laborintensive and time-consuming to build a model instance, and a pure RBAC system lacks flexibility to efficiently adapt to changing users, objects, and security policies. Particularly, it is impractical to manually make (and maintain) user to role assignments and role to permission assignments in industrial context characterized by a large number of users and/or security objects. ABAC has features complimentary to RBAC, and merging RBAC and ABAC has become an important research topic. this paper proposes a new approach to integrating ABAC with RBAC, by modeling RBAC in two levels. the aboveground level is a standard RBAC model extended with "environment". this level retains the simplicity of RBAC, supporting RBAC model verification/review. the "underground" level is used to represent security knowledge in terms of attribute-based policies, which automatically create the simple RBAC model in the aboveground level. these attribute-based policies bring to RBAC the advantages of ABAC: they are easy to build and easy to adapt to changes. Using this framework, we tackle the problem of permission assignment for large scale applications. this model is motivated by the characteristics and requirements of industrial control systems, and reflects in part certain approaches and practices common in the industry.
