Toward Real-time Network-wide Cyber Situational Awareness

In today's complex computer networks, we are constantly facing a risk of data loss, system compromise, or intellectual property theft. The complexity of the networks hinders their effective defense. A Network-wide Cyber Situational Awareness (NwCSA) has been introduced to assist a network security administrator with network security. The concept, however, faces several challenges that hinder an efficient application of the NwCSA in a real-world environment. The challenges include the overload of raw data, low speed of reaction, and a lack of context and unified view on a network. In this paper, we present a novel framework that faces above mentioned challenges. The framework leverages a distributed data stream processing system and methods for real-time big data processing. The framework is evaluated with respect to stated requirements on systems for NwCSA. Moreover, we present a prototype framework implementation and provide lessons learned from its real-world deployment

Shared lives plus

Shared Lives Plus is the UK network for family-based and small-scale ways of supporting adults. Here Alex Fox talks about how the collaboration between their UK-wide network of members and researchers is needed to raise awareness of the value of Shared Lives, Homeshare and micro-enterprise approaches, to strengthen the evidence base for them and to understand better what works and what doesn’t in this cutting edge area of care, support and inclusion

Pervasive Uncertainty in Second Modernity: an Empirical Test

Recent discussion of social change implies that, for a number of reasons, to do with globalisation, shifts in family life styles and labour markets, more critical attitudes toward the authority of officials and experts and greater awareness of possibilities and options, social life is more strongly affected by a sense of uncertainty. It also implies that uncertainty is pervasive and not specifically linked to fears about specific contingencies. It is associated with an orientation towards self-direction and a rejection of tradition and conformity. This thesis has been widely discussed, but rarely tested using quantitative data. This paper uses data from a recent national survey carried out by the ESRC Social Contexts and Responses to Risk network to show that uncertainty and security concerns are strong, but are in fact linked to traditionalism and conformity rather than to a critical and reflexive awareness. A high value is attached to self-direction, but this is linked to privileged social status rather than attitudes of pervasive social uncertainty. In general the values posited by recent discussion seem to be associated more closely with immediate social position than with the society-wide impact of social change.Uncertainty, Traditionalism, Reflexivity, Risk Society, Empirical Test

X-Klaim and Klava: Programming Mobile Code

AbstractHighly distributed networks have now become a common infrastructure for a new kind of wide-area distributed applications whose key design principle is network awareness, namely the ability to deal with dynamic changes of the network environment. Network-aware computing has called for new programming languages that exploit the mobility paradigm as the basic interaction mechanism. In this paper we present the Klaim (Kernel Language for Agent Interaction and Mobility) framework for programming mobile code applications, namely the X Klaim programming language and the Java-based run-time system Klava. In particular, we illustrate how Klava handles mobile code. Finally, an example is shown that is implemented using this framework

Wide-area Situational Awareness Application Developments

This dissertation expands the topics from the wide-area situational awareness application development, system architecture design, to power system disturbance analysis. All the works are grounded on the wide-area Frequency Monitoring Network (FNET). The FNET system takes GPS-synchronized wide-area measurements in a low-cost, easily deployable manner at 120V single-phase power outlet. These synchronized observations enables the monitoring of bulk power systems, and provides critical information for understanding power system disturbances and system operations. Firstly, the work addresses the viability of angle measurement to serve different types of situational awareness applications, including the development of new angle-based event location estimation methods, the design of real-time system visualization framework using angle measurement. Secondly, a sound FNET power system event monitoring and automatic event reporting system framework is introduced, with NERC Frequency Response Initiative (FRI) tasks included to improve power system situational awareness capability. Lastly, the work covers different types of power system disturbance analysis, including the statistical analysis of frequency disturbances in NA power grid from 2008 to 2011; analysis of typical frequency response characteristics of the generation and load loss events in Europe power grid; analysis of some major disturbances in NA power grid from 2010 to 2011; and the inter-area oscillation modal analysis in the WECC system

Negotiating the 'trading zone'. Creating a shared information infrastructure in the Dutch public safety sector

Our main concern in this article is whether nation-wide information technology (IT) infrastructures or systems in emergency response and disaster management are the solution to the communication problems the safety sector suffers from. It has been argued that implementing nation-wide IT systems will help to create shared cognition and situational awareness among relief workers. We put this claim to the test by presenting a case study on the introduction of ‘netcentric work’, an IT system-based platform aiming at the creation of situational awareness for professionals in the safety sector in the Netherlands. The outcome of our research is that the negotiation with relevant stakeholders by the Dutch government has lead to the emergence of several fragmented IT systems. It becomes clear that a top-down implementation strategy for a single nation-wide information system will fail because of the fragmentation of the Dutch safety sector it is supposed to be a solution to. As the US safety sector is at least as fragmented as its Dutch counterpart, this may serve as a caveat for the introduction of similar IT systems in the US
