However, the use of cognitive radio further complicates the security problems in wireless networks and introduces additional challenges. For instance, an attacker may mimic the behavior of a licensed primary user and disrupt the communication strategy of opportunistic spectrum usage of cognitive radio nodes, known as Primary User Emulation Attacks. Another example is a smart jammer, who can scan the spectrum and jam channels selectively. A common characteristic of the attacks in both examples is that they cause anomalous spectrum usage and disrupt the dynamic spectrum access, thus we termed them Anomalous Spectrum Usage Attacks in the context of cognitive radio wireless networks. Anomalous Spectrum Usage Attacks are extremely difficult to detect. In order to address these challenges, we propose a cross-layer framework for security enhancement and attack mitigation. In addition to physical layer sensing, we also take advantage of statistical analysis of the routing information of multiple paths collected by the routing module at the network layer. Inference of congested areas due to spectrum shortage can be made by information fusion and the results from the inference module will be compared to prior knowledge of the primary users, and the suspicious spectrum shortage will be subject to selective auditing, where a manager such as a cluster head will poll more detailed data from the cognitive nodes locating near the suspicious area for further analysis. We use a spectrum-aware split multipath routing as a baseline routing for performance evaluation. The effectiveness of the proposed scheme is demonstrated by extensive simulations.","PeriodicalId":228322,"journal":{"name":"2011 IEEE International Conference on Technologies for Homeland Security (HST)","volume":"2675 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129202130","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 Data Anonymization is an emerging field dedicated to solving this problem, with a main focus on removal of identifiable artifacts that might pierce privacy, such as usernames and IP addresses. However, recent research has demonstrated that more subtle statistical artifacts may yield fingerprints that are just as differen-tiable as the former. This result highlights certain shortcomings in current anonymization frameworks; particularly, ignoring the behavioral idiosyncrasies of network protocols, applications, and users. Network traffic synthesis (or simulation) is a closely related complimentary approach which, while more difficult to execute accurately, has the potential for far greater flexibility. This paper leverages the statistical-idiosyncrasies of network behavior to augment anonymization and traffic-synthesis techniques through machine-learning models specifically designed to capture host-level behavior. We present the design of a system that can automatically learn models for network host behavior across time, then use these models to replicate the original behavior, to interpolate across gaps in the original traffic, and demonstrate how to generate new diverse behaviors. Further, we measure the similarity of the synthesized data to the original, providing us with a quantifiable estimate of data fidelity.","PeriodicalId":228322,"journal":{"name":"2011 IEEE International Conference on Technologies for Homeland Security (HST)","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115740909","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}

To name a few, the Christmas Day 2009 bombing attempt, the UK liquid threat of 2006, the Richard Reid shoe bomb attempt 2002, and the 9/11 highjackings. A number of new technologies and processes have been implemented to meet this increasing threat at the checkpoint such as the liquid, shoes, and laptop procedures which are generally viewed as tolerable annoyances but the body imagers and enhanced pat-downs are viewed more broadly as an invasion of privacy. Yet even with all these new technologies and processes it is not clear that the system will meet the threats facing it. Even more onerous, invasive, costly, and operationally intensive processes are needed to detect the diverse threats aimed at the checkpoint. It seems inconceivable that new measures or some of the more invasive current measures should be used on every passenger. It has been generally agreed that checkpoints and possibly other security processes need to move to a risk based screening system where a measure of threat is accumulated for each passenger using the least invasive approaches first and only applying the most onerous processes to the highest risk passengers. To that end we have been bringing together the key elements of the passenger screening process to develop comprehensive Risk Based screening for the passenger screening checkpoint. This system will include screening technology, ID Authentication, Biometric verification, Background information assessment, and Behavior analysis.","PeriodicalId":228322,"journal":{"name":"2011 IEEE International Conference on Technologies for Homeland Security (HST)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114487090","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}

Readiness as a concept is easy to grasp in principle, yet exceedingly difficult to implement due to the fragmentation of processes within the public safety sector and a fundamental failure to understand the difference between capacity and capability building to achieve Readiness. A strategy is required that will enable heterogeneous public safety communities to achieve operational agility before, during and after a crisis while optimizing their allocation of funding to arrive at a balanced readiness posture. No single individual, department, agency or organization has all of the information necessary to continuously measure readiness within its geographic boundary. Participation in standardized measurement is often stymied by disparate data storage, fragmented processes, budgets, politics, culture and resistance to change. Yet it is recognized that readiness saves lives; therefore a practical approach is required to establish a framework for effectively measuring readiness against a government's prioritized Hazard/Threat Identification and Risk Assessment. The Indiana Department of Homeland Security has made significant progress in uniting all of the major stakeholders into a cohesive public safety ecosystem. Indiana is taking an innovative approach to achieving, measuring, and optimizing readiness. We outline significant lessons learned, best practices, and feasible approaches towards achieving a sustainable state of pervasive readiness which is the concept of readiness as an integral part of the very fabric of a nation.","PeriodicalId":228322,"journal":{"name":"2011 IEEE International Conference on Technologies for Homeland Security (HST)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115954583","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}
