Sound methodologies for constructing security-critical systems are extremely important in order to confront the increasingly varied security threats. As a response to this need, Model-Driven Security has emerged in the early 2000s as a specialized Model-Driven Engineering approach for supporting the development of security-critical systems. In this chapter we summarize the most important developments of Model-Driven Security during the past decade. In order to do so we start by building a taxonomy of the most important concepts of this domain. We then use our taxonomy to describe and evaluate a set of representative and influential Model-Driven Security approaches in the literature. In our development of this topic we concentrate on the concepts shared by Model-Driven Engineering and Model-Driven Security. This allows us to identify and debate the advantages, disadvantages and open issues when applying Model-Driven Engineering to the Information Security domain. This chapter provides a broad view of Model-Driven Security and is intended as an introduction to Model-Driven Security for students, researchers and practitioners. [less ▲]

Model-Driven Security (Mds) is a specialized Model-Driven Engineering (Mde) approach for supporting the development of secure systems. Model-Driven Security aims at improving the productivity of the development process and quality of the resulting secure systems, with models as the main artifact. Among the variety of models that have been studied in a Model-Driven Security perspective, one canmention access control models that specify the access rights. So far, these models mainly focus on static definitions of access control policies, without taking into account the more complex, but essential, delegation of rights mechanism. Delegation is a meta-level mechanism for administrating access rights, which allows a user without any specific administrative privileges to delegate his/her access rights to another user. This paper gives a formalization of access control and delegation mechanisms, and analyses the main hard-points for introducing various advanced delegation semantics in Model-Driven Security. Then, we propose a modular model-driven framework for 1) specifying access control, delegation and the business logic as separate concerns; 2) dynamically enforcing/weaving access control policies with various delegation features into security-critical systems; and 3) providing a flexibly dynamic adaptation strategy.We demonstrate the feasibility and effectiveness of our proposed solution through the proof-of-concept implementations of different component-based systems running on different adaptive execution platforms, i.e. OSGi and Kevoree.

Organized crime now targets one of the most precious wealth in Africa, the wild life. The most affected by the poaching are the Big 5, whose survival requires attention and efforts from everyone, in accordance to his own expertise. Just as Noah (A patriarchal character in Abrahamic religions) was tasked to save every species from the Genesis flood, we envision the NOAH Project to (re)make natural parks as a safe haven. This endeavor requires efficient and effective surveillance which is now facilitated by the use of UAVs. We take this approach further by proposing the use of ICT algorithms to automate surveillance. The proposed intelligent system could inspect a bigger area, recognize potential threats and be manage by non-expert users, reducing the expensive resources that are needed by developing countries to address the problem.

To face continuously growing security threats and requirements, sound methodologies for constructing secure systems are required. In this context, Model-Driven Security (MDS) has emerged since more than a decade ago as a specialized Model-Driven Engineering approach for supporting the development of secure systems. MDS aims at improving the productivity of the development process and quality of the resulting secure systems, with models as the main artifact. This paper presents how we systematically examined existing published work in MDS and its results. The systematic review process, which is based on a formally designed review protocol, allowed us to identify, classify, and evaluate different MDS approaches. To be more specific, from thousands of relevant papers found, a final set of the most relevant MDS publications has been identified, strictly selected, and reviewed. We present a taxonomy for MDS, which is used to synthesize data in order to classify and evaluate the selected MDS approaches. The results draw a wide picture of existing MDS research showing the current status of the key aspects in MDS as well as the identified most relevant MDS approaches.We discuss the main limitations of the existing MDS approaches and suggest some potential research directions based on these insights.

Today’s smart phones are a ubiquitous source of private and confidential data. At the same time, smartphone users are plagued by malicious apps that exploit their given privileges to steal such sensitive data, or to track users without their consent or even the users noticing. Dynamic program analyses fail to discover such malicious activity because apps have learned to recognize the analyses as they execute. In this work we present FlowDroid, a novel and highly precise taint analysis for Android applications. A precise model of Android’s lifecycle allows the analysis to properly handle callbacks, while context, flow, field and objectsensitivity allows the analysis to track taints with a degree of precision unheard of from previous Android analyses. We also propose DroidBench, an open test suite for evaluating the e↵ectiveness and accuracy of taint-analysis tools specifically for Android apps. As we show through a set of experiments using SecuriBench Micro, DroidBench and a set of well-known Android test applications, our approach finds a very high fraction of data leaks while keeping the rate of false positives low. On DroidBench, our approach achieves 93% recall and 86% precision, greatly outperforming the commercial tools AppScan Source and Fortify SCA. [less ▲]

In recent years many researchers in Africa and beyond have devoted considerable resources investigating ways to harness the potential of ICT for improving users’ livelihood in developing areas. Topics and domains of interest appear to be broad with recurring themes and solutions. Unfortunately there are no clear research roadmaps on what is urgent and of the state of the art solutions. In this position paper for the AFRICOMM series of conference, we propose to investigate some priorities for ICT4D in Africa. We believe that our work could motivate researchers and create a synergy around a few important challenges of ICT4D in Africa. [less ▲]

Many threats present in smartphones are the result of interactions between application components, not just artifacts of single components. However, current techniques for identifying inter-application communication are ad hoc and do not scale to large numbers of ap- plications. In this paper, we reduce the discovery of inter-component communication (ICC) in smartphones to an instance of the Interprocedural Distributive Environment (IDE) problem, and develop a sound static analysis technique targeted to the Android platform. We apply this analysis to 1,200 applications selected from the Play store and characterize the locations and substance of their ICC. Experiments show that full specifications for ICC can be identified for over 93% of ICC locations for the applications studied. Further the analysis scales well; analysis of each application took on average 113 seconds to complete. Epicc, the resulting tool, finds ICC vulnerabilities with far fewer false positives than the next best tool. In this way, we develop a scalable vehicle to extend current security analysis to entire collections of applications as well as the interfaces they export. [less ▲]

Modern software systems need to be continuously available under varying conditions. Their ability adapt to their execution context is thus increasingly seen as a key to their success. Recently, many approaches were proposed to design and support the execution of Dynamically Adaptive Systems (DAS). However, the ability of a DAS to evolve is limited to the addition, update or removal of adaptation rules or reconfiguration scripts. These artifacts are very specific to the control loop managing such a DAS and runtime evolution of the DAS requirements may affect other parts of the DAS. In this paper, we argue to evolve all parts of the loop. We suggest leveraging recent advances in model-driven techniques to offer an approach that supports the evolution of both systems and their adaptation capabilities. The basic idea is to consider the control loop itself as an adaptive system. [less ▲]

Software Product Lines (SPLs) are families of products whose commonalities and variability can be captured by Feature Models (FMs). T-wise testing aims at finding errors triggered by all interactions amongst t features, thus reducing drastically the number of products to test. T-wise testing approaches for SPLs are limited to small values of t -- which miss faulty interactions -- or limited by the size of the FM. Furthermore, they neither prioritize the products to test nor provide means to finely control the generation process. This paper offers (a) a search-based approach capable of generating products for large SPLs, forming a scalable and flexible alternative to current techniques and (b) prioritization algorithms for any set of products. Experiments conducted on 124 FMs (including large FMs such as the Linux kernel) demonstrate the feasibility and the practicality of our approach. [less ▲]
