These systems are trained on past or synthetic feature vectors to create a model of anomalous or normal behavior. Thereafter, run-time collected sensor outputs are compared to the model to identify attacks (or the lack of attack). While this approach to detection has been proven to be effective in many environments, it is limited to training on only features that can be reliably collected at detection time. Hence, they fail to leverage the often vast amount of ancillary information available from past forensic analysis and post-mortem data. In short, detection systems do not train (and thus do not learn from) features that are unavailable or too costly to collect at run-time. Recent work proposed an alternate model construction approach that integrates forensic \"privilege\" information---features reliably available at training time, but not at run-time---to improve accuracy and resilience of detection systems. In this paper, we further evaluate two of proposed techniques to model training with privileged information: knowledge transfer, and model influence. We explore the cultivation of privileged features, the efficiency of those processes and their influence on the detection accuracy. We observe that the improved integration of privileged features makes the resulting detection models more accurate. Our evaluation shows that use of privileged information leads to up to 8.2% relative decrease in detection error for fast-flux bot detection over a system with no privileged information, and 5.5% for malware classification.","PeriodicalId":137012,"journal":{"name":"Proceedings of the 3rd ACM on International Workshop on Security And Privacy Analytics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127202959","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}

Cyberbullying can be described as a form of bullying where a perpetrator uses electronic means to cause harm to a victim. With the proliferation of smartphone technology in present times, there has been a steady shift in the usage of OSNs from traditional computers to mobile devices. However, existing systems that defend against cyberbullying are largely applicable only to traditional computing platforms and cannot be directly applied to detect cyberbullying in mobile platforms. To address such a critical issue, we investigate an innovative mobile cyberbullying defense system called MCDefender that can effectively detect and prevent cyberbullying in mobile OSNs. We first analyze the key challenges that differentiate cyberbullying conditions in traditional and mobile platforms. We then investigate a two-level detection mechanism for comprehensive cyberbullying detection in mobile OSNs where cyberbullying can be quickly detected before a cyberbullying message is sent through a mobile device and hidden cyberbullying attacks can be also detected through a more fine-grained and context-aware analysis. To demonstrate the feasibility of our approach, we implement and evaluate an Android application based on MCDefender. Our evaluation results show that our mobile application can detect cyberbullying with a high accuracy of 98.9% for OSNs.","PeriodicalId":137012,"journal":{"name":"Proceedings of the 3rd ACM on International Workshop on Security And Privacy Analytics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125225748","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}
