Making a Living My Way: Necessity-driven Entrepreneurship in Resource-Constrained Communities

Abstract: Entrepreneurship has long been used to create self-employment opportunities to guard against career uncertainty. Yet, little is known about how social technologies impact the day-to-day work of entrepreneurs in resource-constrained contexts. We performed a qualitative study involving interviews with 26 micro-entrepreneurs in Detroit and observations of entrepreneurship events. We found that micro-entrepreneurs in Detroit are often pushed into entrepreneurship in response to unexpected life disruptions, barriers to employment, and desire to benefit the community. Their resource-constrained contexts shape how they use social technologies, such as sharing economy tools and social media groups, particularly with respect to privacy, safety, and professional agency. We expand the discussion in CSCW around what it means to be an entrepreneur and provide implications for how social technologies can be designed to better meet the employment needs of people in resource-constrained communities.

Coexistence of RF-powered IoT and a Primary Wireless Network With Secrecy Guard Zones

Abstract: This paper studies the secrecy performance of a wireless network (primary network) overlaid with an ambient RF energy harvesting Internet of Things (IoT) network (secondary network). The nodes in the secondary network are assumed to be solely powered by ambient RF energy harvested from the transmissions of the primary network. We assume that the secondary nodes can eavesdrop on the primary transmissions due to which the primary network uses secrecy guard zones . The primary transmitter goes silent if any secondary receiver is detected within its guard zone. Using tools from stochastic geometry, we derive the probability of successful connection of the primary network as well as the probability of secure communication. Two conditions must be jointly satisfied in order to ensure successful connection: 1) the signal-to-interference-plus-noise ratio (SINR) at the primary receiver is above a predefined threshold, and 2) the primary transmitter is not silent. In order to ensure secure communication, the SINR value at each of the secondary nodes should be less than a predefined threshold. Clearly, when more secondary nodes are deployed, more primary transmitters will remain silent for a given guard zone radius, which will in turn impact the amount of energy harvested by the secondary network. Our results concretely show the existence of an optimal deployment density for the secondary network that maximizes the density of nodes that are able to harvest sufficient amount of energy. Furthermore, we show the dependence of this optimal deployment density on the guard zone radius of the primary network. In addition, we show that the optimal guard zone radius selected by the primary network is a function of the deployment density of the secondary network. This interesting coupling between the performance of the two networks is studied using tools from game theory. We propose an algorithm that can assist the two networks to converge to Nash equilibrium. The convergence of this algorithm is verified using simulations. Overall, this paper is one of the few concrete works that symbiotically merge tools from stochastic geometry and game theory.

Back To The Epilogue: Evading Control Flow Guard via Unaligned Targets.

Abstract: Attackers use memory corruption vulnerabilities to compromise systems by hijacking control flow towards attacker-controlled code. Over time, researchers proposed several countermeasures, such as Address Space Layout Randomization, Write XOR Execute and Control Flow Integrity (CFI). CFI is one of the most promising solutions, enforcing control flow to adhere to statically determined valid execution paths. To trade with the execution and storage overhead, practical CFI implementations enforce coarser version of CFI. One of the most widely deployed implementations of CFI is the one proposed by Microsoft, named Control Flow Guard (CFG). CFG is currently in place on all Windows operating systems, from Windows 8.1 to the most recent update of Windows 10 (at the time of writing), accounting for more than 500 million machines. In this paper, we show a significant design vulnerability in Windows CFG and propose a specific attack to exploit it: the Back to The Epilogue (BATE) attack. We show that with BATE an attacker can completely evade from CFG and transfer control to any location, thus obtaining arbitrary code execution. BATE leverages the tradeoff of CFG between precision, performance, and backwards compatibility; in particular, the latter one motivates 16-byte address granularity in some circumstances. This vulnerability, inherent to the CFG design, allows us to call portions of code (gadgets) that should not be allowed, and that we can chain together to escape CFG. These gadgets are very common: we ran a thorough evaluation of Windows system libraries, and found many high value targets – exploitable gadgets in code loaded by almost all the applications on 32-bit systems and by web browsers on 64-bit. We also demonstrate the real-world feasibility of our attack by using it to build a remote code execution exploit against the Microsoft Edge web browser running on 64-bit Windows 10. Finally, we discuss possible countermeasures to BATE.

Advances and throwbacks in hardware-assisted security: special session

Abstract: Hardware security architectures and primitives are becoming increasingly important in practice providing trust anchors and trusted execution environment to protect modern software systems. Over the past two decades we have witnessed various hardware security solutions and trends from Trusted Platform Modules (TPM), performance counters for security, ARM's TrustZone, and Physically Unclonable Functions (PUFs), to very recent advances such as Intel's Software Guard Extension (SGX). Unfortunately, these solutions are rarely used by third party developers, make strong trust assumptions (including in manufacturers), are too expensive for small constrained devices, do not easily scale, or suffer from information leakage. Academic research has proposed a variety of solutions, in hardware security architectures, these advancements are rarely deployed in practice.

Twelve-month results of the Italian registry on protected CAS with the mesh-covered CGuard stent: the IRON-Guard study.

Abstract: Introduction Data on perioperative outcomes of new mesh-covered carotid stents have been presented, showing encouraging results1,2. Major complication rates in CGuard carotid artery stenting (CAS) procedures range from 0 to 2.5% at 30 days1,2. These data underline the feasibility and safety of the CGuardTM stent (InspireMD, Tel Aviv, Israel) in preventing off-table events in the so-called plaque healing period, that is to say after the intraoperative embolism risk has been overcome. The IRON-Guard registry2 has continued to collect data from the first 200 patients treated by CGuard stent implantation. The present paper reports the one-year follow-up data completed by all patients.

An Analytical Study of Security and Challenging Issues in Social Networking as an Emerging Connected Technology

Evacuation simulation considering action of the guard in an artificial attack.

Abstract: To investigate the evacuation behaviors of pedestrians considering action of the guard and develop an effective evacuation strategy in the artificial attack, an extended floor field model was proposed. In this model, the assault on pedestrians, the death of pedestrians and the capture of the guard were involved simultaneously. An alternative evacuation strategy which can largely reduce the number of death was developed and effects of several key parameters such as the deterrence radius and capture distance on evacuation dynamics were studied. Results show that congestion near the exit has dual effects. More specially, the guard could catch all attackers in a short time because the attackers would have more concentrated distribution, but more casualties would happen because pedestrians are hard to escape the attack due to congestion. In contrast, when pedestrians have more preference of approaching the guard, although the guard would take more time to capture the attackers result from the dispersion of attackers, the death toll would decrease. One of the reason is the dispersal of the crowd and the decrease in congestion would be beneficial for escape. Another is the attackers would be killed before launching the attack to the people those are around the guard, in other words, the guard would protect a large number of pedestrians from being killed. Moreover, increasing capture distance of the guard can effectively reduce the casualties and the catch time. As the deterrence radius reflecting the tendency of escaping from the guard for attackers rises, it would become more difficult for the guard to catch the attackers and more casualties are caused. However, when the deterrence radius reaches a certain level, the number of deaths would be reduced because the attackers would prefer to stay as far away as possible from instead of the position where they could attack more people.

Cloud-Assisted Key Distribution in Batch for Secure Real-Time Mobile Services

Abstract: Establishing promising and efficient key distribution is the cornerstone of security when applying cryptographic methods to guard the privacy of smart devices in the Internet of Things (IoT). However, when using conventional key distribution methods in real-time mobile services, it is usually deficient to build multiple channels with strong security simultaneously on a single data server. Therefore, we focus our research on collecting or monitoring real-time and remote data, which is commonly observed in the health care field of the IoT. In this research, there are difficulties to apply the conventional key distribution approaches during interactions when considering both security and efficiency. Moreover, when preserving personal privacy, anonymity is also important in key distribution processes. We design a system of real-time mobile services and the related security requirements in this paper, and apply a novel and interesting Identity-Based Key Encapsulation Mechanism (IBKEM) to instantiate our system and achieve anonymous key distribution with only one-pass communication for mobile clients in batch. Our instantiated system demonstrates both strong security and practice.

Low Cost Efficient Deliverying Video Surveillance Service to Moving Guard for Smart Home.

Abstract: Low-cost video surveillance systems are attractive for Smart Home applications (especially in emerging economies). Those systems use the flexibility of the Internet of Things to operate the video camera only when an intrusion is detected. We are the only ones that focus on the design of protocols based on intelligent agents to communicate the video of an intrusion in real time to the guards by wireless or mobile networks. The goal is to communicate, in real time, the video to the guards who can be moving towards the smart home. However, this communication suffers from sporadic disruptions that difficults the control and drastically reduces user satisfaction and operativity of the system. In a novel way, we have designed a generic software architecture based on design patterns that can be adapted to any hardware in a simple way. The implanted hardware is of very low economic cost; the software frameworks are free. In the experimental tests we have shown that it is possible to communicate to the moving guard, intrusion notifications (by e-mail and by instant messaging), and the first video frames in less than 20 s. In addition, we automatically recovered the frames of video lost in the disruptions in a transparent way to the user, we supported vertical handover processes and we could save energy of the smartphone's battery. However, the most important thing was that the high satisfaction of the people who have used the system.

A Survey and Comparison of Performance Evaluation in Intrusion Detection Systems

Abstract: Performance evaluation is an important aspect when designing a system. However, with intrusion detection systems (IDS), there are many other factors to consider. What are the metrics which are being used to compare the systems? Which attacks do particular approaches detect? Is the solution able to adapt and recognize new attacks, or is it limited to a set of attacks which were known at the time the system was designed? This chapter provides an overview of some of these concerns and tries to highlight in each surveyed IDS which metrics are used for performance evaluation, whether or not the solution is flexible, and which attacks the IDS is able to detect. This will provide the reader with a good basis for choosing the type of approach to use to guard against attacks, or as a basis to dig deeper into a particular aspect of intrusion detection.

New York City’s window guard policy: four decades of success

Abstract: Background Preventing child falls from windows is easily accomplished by installing inexpensive window-limiting devices but window falls remain a common cause of child injuries. This article describes the history and evolution of the New York City (NYC) window guard rule,which requires building owners to install window guards in apartments housing children aged ≤10 years. The NYC window guard rule was the first directive of its kind in the USA when it was adopted in 1976, and it has led to a dramatic and long-lasting reduction in child window fall-related injuries and deaths. Methods Data about the history of the window guard rule were obtained by reviewing programmatic records, correspondence, legal decisions and the published literature. In addition, key informant interviews were conducted with programme staff. Results and Discussion This article describes each stage of policy development, starting with epidemiological studies defining the scope of the problem in the 1960s and pilot-testing of the window guard intervention. We describe the adoption, implementation and enforcement of the rule. In addition, we show how the rule was modified over time and document the rule’s impact on window fall incidence in NYC. We describe litigation that challenged the rule’s constitutionality and discuss the legal arguments used by opponents of the rule. Finally, we discuss criminal and tort liability as drivers of compliance and summarise lessons learnt.
