  • Hunting the Unknown - White-Box Database Leakage Detection

    Springer

    Data leakage causes significant losses and privacy breaches worldwide. In this paper we present a white-box data leakage detection system to spot anomalies in database transactions. We argue that our approach represents a major leap forward w.r.t. previous work because: i) it significantly decreases the False Positive Rate (FPR) while keeping the Detection Rate (DR) high; on our experimental dataset, consisting of millions of real enterprise transactions, we measure a FPR that is orders of…

    Data leakage causes significant losses and privacy breaches worldwide. In this paper we present a white-box data leakage detection system to spot anomalies in database transactions. We argue that our approach represents a major leap forward w.r.t. previous work because: i) it significantly decreases the False Positive Rate (FPR) while keeping the Detection Rate (DR) high; on our experimental dataset, consisting of millions of real enterprise transactions, we measure a FPR that is orders of magnitude lower than in state-of-the-art comparable approaches; and ii) the white-box approach allows the creation of self-explanatory and easy to update profiles able to explain why a given query is anomalous, which further boosts the practical applicability of the system.

  • Database Anomalous Activities: Detection and Quantification

    Proceeding of International Conference on Security and Cryptography (SECRYPT) 2013

    The disclosure of sensitive data to unauthorized entities is a critical issue for organizations. Timely detection of data leakage is crucial to reduce possible damages. Therefore, breaches should be detected as early as possible, e.g., when data are leaving the database. In this paper, we focus on data leakage detection by monitoring database activities. We present a framework that automatically learns normal user behavior, in terms of database activities, and detects anomalies as deviation…

    The disclosure of sensitive data to unauthorized entities is a critical issue for organizations. Timely detection of data leakage is crucial to reduce possible damages. Therefore, breaches should be detected as early as possible, e.g., when data are leaving the database. In this paper, we focus on data leakage detection by monitoring database activities. We present a framework that automatically learns normal user behavior, in terms of database activities, and detects anomalies as deviation from such behavior. In addition, our approach explicitly indicates the root cause of an anomaly. Finally, the framework assesses the severity of data leakages based on the sensitivity of the disclosed data.

  • Privacy-Aware Web Service Composition and Ranking

    Procs. of the IEEE 20th International Conference on Web Services (ICWS), 2013

    In this paper, we propose a novel privacy-preserving Web service composition and selection approach which (i) makes it possible to verify the compliance between users’ privacy requirements and providers’ privacy policies and (ii) ranks the composite Web services with respect to the privacy level they offer. We demonstrate our approach using a travel agency Web service as an example of service composition.
