Host-based anomaly detectors generate alarms by inspecting audit logs for suspicious behavior. Unfortunately, evaluating these anomaly …

This experimental study presents a number of issues that pose a challenge for practical configuration tuning and its deployment in data …

Advanced Persistent Threats (APTs) are difficult to detect due to their low-and-slow attack patterns and frequent use of zero-day …

The growth of programming in the sciences has been explosive in the last decade. This has facilitated the rapid advancement of science …

A cloud provider that can technically determine tenants’ operations may be compelled to disclose such activities by law …

System level provenance is of widespread interest for applications such as security enforcement and information protection. However, …

Valuable, sensitive, and regulated data flow freely through distributed governing the collection, use, and management of such data? We …

The execution of distributed data processing workloads (such as those running on top of Hadoop or Spark) in cloud environments presents …

The Internet of Things promises a connected environment reacting to and addressing our every need, but based on the assumption that all …

Identifying the root cause and impact of a system intrusion remains a foundational challenge in computer security. Digital provenance …

Intrusion detection is an arms race; attackers evade intrusion detection systems by developing new attack vectors to sidestep known …

Open data and open-source software may be part of the solution to science’s “reproducibility crisis”, but they are insufficient to …

Managing privacy in the IoT presents a significant challenge. We make the case that information obtained by auditing the flows of data …

Data provenance describes how data came to be in its present form. It includes data sources and the transformations that have been …

In the last few decades, data-driven methods have come to dominate many fields of scientific inquiry. Open data and open-source …

We present FRAPpuccino (or FRAP), a provenance-based fault detection mechanism for Platform as a Service (PaaS) users, who run many …

Unikernels are a rapidly emerging technology in the world of cloud computing. Unikernels build on research on library operating systems …

Internet of Things (IoT) applications, systems and services are subject to law. We argue that for the IoT to develop lawfully, there …

The usual approach to security for cloud-hosted applications is strong separation. However, it is often the case that the same data is …

To realize the broad vision of pervasive computing, underpinned by the “Internet of Things” (IoT), it is essential to break down …
