The importance of effective multilateral security networks is widely recognised in Australia and internationally as being essential to facilitate the large-scale sharing of information required to respond to the threat of terrorism. Australian national security agencies are currently constructing networks in order to bring the diverse national and international security agencies together to achieve this. This paper examines this process of security network formation in the area of critical infrastructure protection, with particular emphasis on airport security. We address the key issues and factors shaping network formation and the dynamics involved in network practice. These include the need for the networks to extend membership beyond the strictly defined elements of national security; the integration of public and private ‘nodes’ in counter-terrorism ‘networks’; and the broader ‘responsibilisation’ of the private sector and the challenges with ‘enabling’ them in counter-terrorism networks. We argue that the need to integrate public and private agencies in counter-terrorism networks is necessary but faces considerable organisational, cultural, and legal barriers.

Surveillance and security at sports mega events have been the subject of considerable scholarly attention. Events such as the Olympic Games and Fédération Internationale de Football Association (FIFA) World Cups have become occasions of almost unparalleled economic, political and social significance. In the lead up to the London 2012 Olympic Games, scholars have examined issues such as the ‘security legacies’ of sports mega events, the infrastructures and technologies used in an attempt to secure these events, and the planning mentalities underpinning the staggering ‘security spectacle’ of these globally televised events. This paper deals with the subject of how surveillance and security practices at sports mega events are organised. It uses the emerging paradigm of ‘security networks’ to call attention to some important issues involving the entire ‘security assemblage’ that accompanies these mega events. The paper presents five levels of analysis—structural, cultural, policy, technological and relational—to examine these practices and documents several key areas for further research on sports mega events.

Security networks are organisational forms involving public, private and hybrid actors or nodes that work together to pursue security-related objectives. While we know that security networks are central to the governance of security, and that security networks exist at multiple levels across the security field, we still do not know enough about how these networks form and function. Based on a detailed qualitative study of networks in the field of ‘high’ policing in Australia, this article aims to advance our knowledge of the relational properties of security networks. Following the organisational culture literature, the article uses the concept of a ‘group’ as the basis with which to analyse and understand culture. A group can apply to networks (‘network culture’), organisations (‘organisational culture’) and sections within and between organisations (‘occupational subcultures’). Using interviews with senior members of security, police and intelligence agencies, the article proceeds to analyse how cultures form and function within such groups. In developing a network perspective on occupational culture, the article challenges much of the police culture(s) literature for concentrating too heavily on police organisations as independent units of analysis. The article moves beyond debates between integrated or differentiated organisational cultures and questions concerning the extent to which culture shapes particular outcomes, to analyse the ways in which security nodes relate to one another in security networks. If there is one thing that should be clear it is that security nodes experience cultural change as they work together in and through networks.

How do local homeland security organizations respond to catastrophic events such as hurricanes and acts of terrorism? Among the most important aspects of this response are these organizations ability to adapt to the uncertain nature of these "focusing events" (Birkland 1997). They are often behind the curve, seeing response as a linear process, when in fact it is a complex, multifaceted process that requires understanding the interactions between the fiscal pressures facing local governments, the institutional pressures of working within a new regulatory framework and the political pressures of bringing together different levels of government with different perspectives and agendas. ^ This dissertation has focused on tracing the factors affecting the individuals and institutions planning, preparing, responding and recovering from natural and man-made disasters. Using social network analysis, my study analyzes the interactions between the individuals and institutions that respond to these "focusing events." In practice, it is the combination of budgetary, institutional, and political pressures or constraints interacting with each other which resembles a Complex Adaptive System (CAS). ^ To investigate this system, my study evaluates the evolution of two separate sets of organizations composed of first responders (Fire Chiefs, Emergency Management Coordinators) and community volunteers organized in the state of Florida over the last fifteen years. Using a social network analysis approach, my dissertation analyzes the interactions between Citizen Corps Councils (CCCs) and Community Emergency Response Teams (CERTs) in the state of Florida from 1996–2011. It is the pattern of interconnections that occur over time that are the focus of this study. ^ The social network analysis revealed an increase in the amount and density of connections between these organizations over the last fifteen years. The analysis also exposed the underlying patterns in these connections; that as the networks became more complex they also became more decentralized though not in any uniform manner. The present study brings to light a story of how communities have adapted to the ever changing circumstances that are sine qua non of natural and man-made disasters.^

Security networks are increasing in number and in importance across the security field as a means of providing inter-agency coordination. On the basis of a detailed qualitative study of networks in the field of national security in Australia, this article aims to advance our knowledge of the internal properties of security networks and conditions shaping their performance. It places ‘cooperation’, ‘coordination’ and ‘collaboration’ on a continuum, with cooperation at one end and collaboration at the other end, and aims to illustrate how each of these ‘Cs’ shape the performance of security networks. The central argument is that the performance of security networks increases as the network moves from cooperation to collaboration. Drawing on interviews with senior members of security, law enforcement and intelligence agencies, the article aims to highlight the lessons for how to strategically manage security networks in ways that promote collaboration.

Purpose

– The purpose of this paper is to explore the underlying relational properties of security networks by focusing specifically on the relationship between formal and informal ties, and interpersonal and inter-organisational trust.

Design/methodology/approach

– The research is based on 20 qualitative interviews with senior members of police and security agencies across the field of counter-terrorism in Australia.

Findings

– The findings suggest that the underlying relational properties of security networks are highly complex, making it difficult to distinguish between formal and informal ties, interpersonal and inter-organisational trust. The findings also address the importance of informal ties and interpersonal trust for the functioning of organisational security networks.

Research limitations/implications

– The research is exploratory in nature and extends to a number of organisational security networks in the field of counter-terrorism in Australia. While it is anticipated that the findings will be relevant in a variety of contexts, further research is required to advance our knowledge of the implications and properties of informal social networks within defined network boundaries.

Practical implications

– The findings suggest that the functioning of security networks is likely to be highly dependent on the underlying social relationships between network members. This has practical implications for those responsible for designing and managing security networks.

Originality/value

– The paper calls attention to a very understudied topic by focusing on the dynamics of informal ties and interpersonal trust within organisational security networks.

The availability of electricity is fundamental to modern society. It is at the top of the list of critical infrastructures and its interruption can have severe consequences. This highly important system is now evolving to become more reliable, efficient, and clean. This evolving infrastructure has become known as the smart grid; and these future smart grid systems will rely heavily on ICT. This infrastructure will require many servers and due to the nature of the grid, many of these systems will be geographically diverse requiring communication links. At the heart of this ICT infrastructure will be security. At each level of the smart grid from smart metering right through to remote sensing and control networks, security will be a key factor for system design consideration. With an increased number of ICT systems in place the security risk also increases. In this paper the authors discuss the changing nature of security in relation to the smart grid by looking at the move from legacy systems to more modern smart grid systems. The potential planes of attack for future smart grid systems are identified, and the general anatomy of a cyber-attack is presented. The authors then introduce the various threat levels of different types of attack and the mitigation techniques that could be put in place for each. Finally, the authors' introduce a Phasor Measurement Unit (PMU) communication system (operated by the authors) that can be used as a test-bed for some of the proposed future security research.

Le présent travail de recherche se propose d’analyser les dispositifs de gouvernance nodale de la sécurité locale en France, alors que le paradigme a vu le jour et s’est développé dans les pays anglo-saxons fortement décentralisés. C’est qu’en France les dispositifs de gouvernance nodale s’apparentent bien plus à un dialogue entre central et local qu’entre secteur public et privé. La recherche identifie ainsi les caractéristiques de la gouvernance nodale au cœur des dispositifs partenariaux de la sécurité locale, supportés par le Contrat Local de Sécurité (CLS), le Conseil Local de Sécurité et de Prévention de la Délinquance (CLSPD) ou encore le Groupe Local de Traitement de la Délinquance (GLTD). La recherche identifie ainsi les stratégies de décentrage de l’État et de transfert de la production de sécurité vers une diversité d’acteurs locaux, dont les maires et les services municipaux. Une diversité de politiques publiques locales de sécurité de pertinences différentes voit alors le jour. Le premier enseignement de cette recherche est l’importance du rôle joué par le node super-structurel, que nous appelons super-node et qui regroupe le maire ou l’élu local à la sécurité, le responsable de la police d’État, celui de la police municipale et le représentant de l’État. Il apparaît que dans le dispositif de gouvernance nodale, ce groupe informel génère la dynamique collective qui permet de regrouper, tant les producteurs que les consommateurs de sécurité locale gravitant au sein du réseau local de sécurité. La quarantaine d’entrevues qualitatives permet également d’identifier que la Justice, productrice de sécurité comme peut l’être aussi la sécurité privée ou la médiation sociale, apparaît plus distante que ce que pouvait laisser penser l’étude des textes réglementaires organisant le partenariat. Les bailleurs sociaux, les transporteurs et l’Éducation nationale apparaissent clairement comme des acteurs importants, mais périphériques de sécurité, en intégrant cette « famille élargie » de la sécurité locale. Le deuxième enseignement est relatif au fonctionnement même du dispositif nodal ainsi que du super-node, la recherche permettant d’identifier les ressources mutualisées par l’ensemble des nodes. Cela permet également d’identifier les mécanismes de répartition des tâches entre les différents acteurs et plus particulièrement entre les deux organisations policières d’État et municipale, travaillant autant en compétition, qu’en complémentarité. Cette recherche explore également le rôle joué par l’information dans le fonctionnement du super-node ainsi que l’importance de la confiance dans les relations interpersonnelles des représentants des nodes au sein du super-node. Enfin, l’étude permet également de mettre en perspective les limites du dispositif actuel de gouvernance nodale : le défaut avéré d’outils performants permettant d’informer convenablement le super-node quant aux phénomènes de violence ainsi que d’évaluer l’efficience du dispositif. Cela permet également de questionner l’autonomie des dispositifs de gouvernance nodale, la confiance pouvant ouvrir à la déviance et la collégialité au défaut de la traçabilité de la responsabilité. La fracture avec la société civile apparaît clairement et ne facilite pas le contrôle sur un mode de production de sécurité qui se développe en parallèle des dispositifs traditionnels de démocratie locale.

La presente investigación analiza los principales retos que afectan la cooperación e integración de los cuerpos policiales latinoamericanos en la lucha contra el narcotráfico. Para realizar dicho análisis se toma como caso de estudio AMERIPOL, organización creada en el año 2007 y que actualmente constituye el único mecanismo de cooperación policial en el hemisferio americano. Se considera que la cooperación e integración de los cuerpos policiales en la lucha contra el narcotráfico en la región enfrentan dos retos principales: la disparidad de los marcos jurídicos entre los Estados y la descoordinación política. Estos retos suponen la existencia de factores que impiden una política de cooperación conjunta contra las drogas y por tanto, el desarrollo de actitudes aislacionistas que limitan la cooperación en contra de éste flagelo

Organisational culture is a complex and heavily contested concept. Not only is it difficult to define what organisational culture is, but it is also very difficult to analyse how it guides and constrains behaviour, and whether and how organisational cultures change. The central argument of this article is that organisational networks can effect cultural change and that the terms ‘structural’ and ‘relational’, which are commonly used to conceptualise the properties of networks, may also provide a useful conceptual framework for understanding cultural change. While there has been some attention directed to the effects of organisational culture for networks, there has been very little attention placed on the potential for networks to shape organisational culture. Based on a detailed qualitative study of networks in the field of ‘high’ policing in Australia, the article draws on interviews with senior members of police and security agencies to explore organisational culture and cultural change. The article puts forward a network perspective on cultural change and aims to advance our knowledge of how security nodes can experience cultural change as they work together in and through networks.

Vehicular Ad-hoc Networks (VANETs) can make roads safer, cleaner, and smarter. It can offer a wide range of services, which can be safety and non-safety related. Many safety-related VANETs applications are real-time and mission critical, which would require strict guarantee of security and reliability. Even non-safety related multimedia applications, which will play an important role in the future, will require security support. Lack of such security and privacy in VANETs is one of the key hindrances to the wide spread implementations of it. An insecure and unreliable VANET can be more dangerous than the system without VANET support. So it is essential to make sure that “life-critical safety” information is secure enough to rely on. Securing the VANETs along with appropriate protection of the privacy drivers or vehicle owners is a very challenging task. In this work we summarize the attacks, corresponding security requirements and challenges in VANETs. We also present the most popular generic security policies which are based on prevention as well detection methods. Many VANETs applications require system-wide security support rather than individual layer from the VANETs’ protocol stack. In this work we will review the existing works in the perspective of holistic approach of security. Finally, we will provide some possible future directions to achieve system-wide security as well as privacy-friendly security in VANETs.
