Recently, some new ways of adhoc cooperation have been demonstrated during the hurricane Irene and the earthquake in Japan. In such emergency situations, OSNs have already taken a significant role as alternative social media that support altruistic information sharing and cooperation among people. However, existing cooperation approaches have not been well-organized and are highly vulnerable to security threats such as a disclosure of users' identities and the leakage of other private data due to the lack of secure cooperation mechanisms. To support secure and effective cooperation in OSNs, in this paper, we propose the Social CRiBAC (Community-centric Role interaction Based Access Control) model, which extends the existing CRiBAC model [1] for use in OSNs to support cooperation among users. To verify the feasibility of the proposed model, we have implemented a prototype application on Facebook and demonstrate its applicability with two working examples.","PeriodicalId":225191,"journal":{"name":"8th International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128468058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Network traffic data exhibit spatiotemporal patterns. Learning and maintaining the currently elusive rich semantics based on analyzing such patterns would help in mitigating those challenges. In this paper, we propose the concept of a network “memory” (or NetMem) to support smarter data-driven network operations as a foundational component of next generation networks. NetMem will enable networking objects to understand autonomously, at real-time, on-demand, and at low cost semantics with different levels of granularity and related to various network elements. Guided by the fact that human activities exhibit spatiotemporal data patterns; and the human memory extracts and maintains semantics to enable accordingly learning and predicting new things, we design NetMem to mimic functionalities of that memory. NetMem provides capabilities for semantics management through uniquely integrating data virtualization for homogenizing massive data originating from heterogeneous sources, cloud-like scalable storage, associative rule learning to recognize data patterns, and hidden Markov models for reasoning and extracting semantics clarifying normal/abnormal behavior. NetMem provides associative access to data patterns and relevant derived semantics to enable enhancements in early anomaly detection, more accurate behavior prediction and satisfying QoS requirements with better utilization of resources. We evaluate NetMem using simulation. Preliminary results demonstrate the positive impact of NetMem on various network management operations.","PeriodicalId":225191,"journal":{"name":"8th International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom)","volume":"372 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126714050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many security-oriented organizations deploy multi-level systems which enforce one directional information flow in a lattice of security labels. However, traditional lattice constructions are not suitable for accommodating external consultants, since such consultants are not “true insiders” but rather “expedient insiders” who should receive much more limited privileges than employees. An authorization model for group-centric collaboration with expedient insiders (GEI) has been recently proposed, wherein organizations create groups and replicate the organizational lattice with selected content for such collaborations [4]. Motivated by GEI, in this paper, we formulate a novel lattice construction wherein a new collaboration category is introduced for each new collaboration group, in a manner significantly different from the usual process of defining new security categories in a lattice. In particular, a collaboration category brings together only the required objects and users. We develop a formal model for lattices with collaborative compartments (LCC) comprising administrative and operational parts covering the life-cycle of such collaborations. We formally prove the equivalence of LCC and GEI, thereby precisely characterizing the information flow and security properties of GEI which heretofore had only been informally considered. This equivalence shows that GEI can be realized via LBAC with minimal operational disruptions.","PeriodicalId":225191,"journal":{"name":"8th International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115050054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
