Previous works suggested different approaches to implementing service chaining. Their goal is to enhance the performance of the middleboxes and satisfy the expectations of the cloud providers and users. To meet these expectations, the delay factor, i.e., flow through the low-cost paths, as well as the best node processing factor, are considered. Achieving these two goals simultaneously turns the middlebox optimal placement into an NP-hard problem. Therefore, when the problem size is large, it is infeasible to obtain an optimal solution at a reasonable time. One of the important issues which has not been considered in the previous works is stateful optimal placement when receiving a new request. Due to resource constraints as well as financial costs for the customers, it is not possible to create functions for all requests. Therefore, not only it is possible to integrate the same network functions between new flows, but it will also be examined between new on-demand network functions as well as existing ones. Our proposed approach not only reduces the creation of network functions that can be cost-effective for the customer but also because of the migration of previous network functions (integration with on-demand network functions) to optimize new requests, overall, it will optimize the entire network cost over time. We formulated the problem as 0-1 programming problem. The results of this article are based on a fat-tree data center. To show that our stateful solution is scalable in large networks, we use network zoning and topology partitioning heuristics. Our simulations show that we were able to scale our placement model to a network with 54K nodes and 1.5M edges.

security and the smart city: A systematic review

SUSTAINABLE CITIES AND SOCIETY 2020年 55卷

The implementation of smart technology in cities is often hailed as the solution to many urban challenges such as transportation, waste management, and environmental protection. Issues of security and crime prevention, however, are in many cases neglected. Moreover, when researchers do introduce new smart security technologies, they rarely discuss their implementation or question how new smart city security might affect traditional policing and urban planning processes. This systematic review explores the recent literature concerned with new 'smart city' security technologies and aims to investigate to what extent these new interventions correspond with traditional functions of security interventions. Through an extensive literature search we compiled a list of security interventions for smart cities and suggest several changes to the conceptual status quo in the field. Ultimately, we propose three clear categories to categorise security interventions in smart cities: Those interventions that use new sensors but traditional actuators, those that seek to make old systems smart, and those that introduce entirely new functions. These themes are then discussed in detail and the importance of each group of interventions for the overall field of urban security and governance is assessed.

Network functions virtualization (NFV), along with software-defined networking (SDN), drives a new change in networking infrastructure with respect to designing, deploying, and managing various network services. In particular, NFV has potential to significantly reduce the hardware cost, greatly improve operational efficiency, and dramatically shorten the development lifecycle of network service. It also makes network functions and services much more adaptive and scalable. Despite the promising advantages of NFV, security remains to be one of the vital concerns and potential hurdle, as attack surface becomes unclear and defense line turns to be blurred in the virtualization environment. This survey is therefore devoted to analyzing NFV from a security perspective. We first analyze security threats of five well-defined NFV use cases, with an objective to establishing a comprehensive layer-specific threat taxonomy. Second, we conduct in-depth comparative studies on several security mechanisms that are applied in traditional scenarios and in NFV environments. The purpose is to analyze their implicit relationships with NFV performance objectives in terms of feasibility, agility, effectiveness, and so on. Third, based on the established threat taxonomy and the analyzed security mechanisms, we provide a set of recommendations on securing NFV based services, along with the analysis on the state-of-the-art security countermeasures. A resulting holistic security framework is intended to lay a foundation for NFV service providers to deploy adaptive, scalable, and cost-effective security hardening based on their particular needs. Some future research directions are finally discussed.

Extensive use of information systems and information technologies in regular practice and in particular in the banking sector has led to its critical dependency on these systems and technologies. This is why it is necessary to protect these systems and to model the risks that threaten them. Two main approaches are currently in use - analytical and empirical. The analytical approach is based on a "Good Practice" technique, while the empirical approach uses the technique of sharing information about resolved security incidents. The article analyzes the basic principles of both approaches and assesses their suitability for the banking sector. The analysis result shows that it is necessary to combine both approaches in order to successfully manage information security in banks.

New technologies such as vehicle-to-X (V2X) communication and advanced driver assistance systems (ADAS) are on the rise. They are mainly used to increase road safety as well as traffic efficiency and to provide customers with infotainment features. However, these new technologies also provide the opportunity to combat vehicle related crime which is present in our society. In this paper, we summarize current measures tackling vehicle related crime and propose a security function, namely electronic decal, based on V2X communication to combat vehicle theft. Furthermore, we propose an integration of the electronic decal functionality into the message format based on the latest standardization progress of the European Telecommunications Standards Institute (ETSI).

Among numerous types of criminal activities, vehicle related crime contributes to personal injury as well as to economic losses. Over the last 10 years vehicle related crime continuously constitutes over 10% of all crime in Germany. However, vehicle related crime is not particularly a German phenomenon but even more a worldwide problem which does not respect national borders. Meanwhile, connected mobility gains importance and vehicles are increasingly equipped with advanced driver assistance systems (ADAS). Additionally, the penetration of consumer electronics (CE) increases constantly. Hence, it seems promising to use these new technologies to tackle vehicle related crime. But to be able to apply these new technologies successfully against vehicle related crime, a systematic approach to understand these crimes in detail is necessary. To address this challenge, we apply two criminological theories, Rational Choice Perspective and Situational Crime Prevention, to the vehicle related context. We also provide an innovative idea for a countermeasure based on information and communication technologies (ICT).
