Empowering aged care nurses to deliver person-centred care: Enabling nurses to shine
'Elsevier BV', 2018Co-Authors: Marriott-statham Kelly, Mackay Maria, Enna Ngaire, Mackay JacintaAbstract:** From PubMed via Jisc Publications Router. ** History: received 31-05-2017; revised 30-03-2018; accepted 22-05-2018.In this paper, the authors will describe the journey of registered nurses across a series of workshops as part of a research project that was undertaken in a regional aged care service in New South Wales, Australia. The aim of the project was to empower the participant registered nurses to positively influence the health care workplace culture within the residential care home by raising consciousness about their own practice. Registered nurses were actively involved in this Reconnaissance Phase of a participatory action research project through practice development principles and methods. Registered nurses determined the content and the outcomes of the overall program. The researchers evaluated the impact of a series of workshops, designed to develop skills and knowledge using nominal group technique. Results revealed registered nurses perceived they were empowered to flourish, and developed an understanding of the uniqueness of their role. A shared understanding of the role of the registered nurse in the aged care setting was fundamental in enabling them to feel empowered to lead their team and contribute positively to the workplace culture. Overall, the outcomes of this project have positively impacted workplace culture.sch_nur31pub5395pu

S3N - Smart Solution for Substation Networks, an architecture for the management of communication networks in power substations
Medellín, 2018Co-Authors: Leal Piedrahita, Erwi AlexándeAbstract:Today, the communications network has become an essential element to the operation of any type of organization or infrastructure, such is the case of the electrical power substations. Such networks in particular, demand high levels of availability and reliability, as the substation is a key element in the chain of energy generation and distribution. However, although recent network modernization introduced new features that allow optimizing the operation of the substation, the variety of devices present in such environment (Intelligent Electronic Devices (IEDs), Merging Units (MUs), Network Switches, IEEE 1588 Master Clock) and the huge set of application-level protocols (Sampled Measured Values (SV), Generic Object Oriented Substation Event (GOOSE), Manufacturing Message Specification protocol (MMS), Precision Time Protocol (PTP), among others), increase the management complexity. Nevertheless, in recent years, data networks have been permeated by two major trends aiming to facilitate the administration of complex networks: Software Defined Networking (SDN) and virtualizationtechnologies, which make the network management more flexible and enable the rapid development and deployment of network services. This thesis proposes a set of contributions to solve the research challenges around of the current operation of a power substation communication network that have not been tackled by the research community. To do that, it performs a comprehensive review of the appropriation of SDN as an enabler in the management and operation of the power substations communication networks. The first research challenge we identified in this work is that, to the best of our knowledge, there are not research works proposing a complete architecture for the management of the communications networks of the power substation; also existing works do not introduce the virtualization technologies as an enabler in this environment. They only present how the application of SDN concepts may improve the performance of different communication tasks in power substations. This thesis introduces a novel architecture called Smart Solution for Substation Networks (S3N), which presents a different way to represent the interaction among all elements involved in the operation of the power substation, taking the communications network as the central point and the SDN paradigm as a key element of its formulation. The second challenge found in this work is that there is no unique criterion to define the structure of the network topology since, in every power substation, the end user implements their own topologies or the topology suggested by a vendor. In this context, this thesis presents a methodology to specify and characterize a reliable topology that vii guarantees fault-tolerance, according to the guidelines described in the architecture S3N. In addition, this thesis presents alternative SDN solutions for loops-based topologies in the proposed network topology which would be technically unfeasible using common network protocols. These solutions include algorithms to solve problems related to the broadcast and multicast traffic management. Also, we discovered that, although the communication networks of modern electrical substations provide major benefits, various research articles have evidenced several vulnerabilities related to the operation protocols in this critical infrastructure. This thesis, in order to improve the security, presents two strategies to detect intrusions and one SDN approach to mitigate attacks in the Reconnaissance Phase. Finally, all these contributions would not be enough to guarantee a reliable operation without mechanisms to bring traffic differentiation and provisioning. This thesis makes the best out of the architecture proposed to deploy Quality of Service (QoS) inside power substation communication networks, under the SDN paradigm

detection of spammers in the Reconnaissance Phase by machine learning techniques
International Conference on Inventive Computation Technologies, 2018Co-Authors: J Jeyasudha, G UshaAbstract:Reconnaissance Phase is where attackers identify their targets and how to collect information from professional social networks which can be used to select and exploit targeted employees to penetrate in an organization. Here, a framework is proposed for the early detection of attackers in the Reconnaissance Phase, highlighting the common characteristic behavior among attackers in professional social networks. And to create artificial honeypot profiles within the organizational social network which can be used to detect a potential incoming threat. By analyzing the dataset of social Network profiles in combination of machine learning techniques, A DspamRPfast model is proposed for the creation of a classifier system to predict the probabilities of the profiles being fake or malicious and to filter them out using XGBoost and for the faster classification and greater accuracy of 84.8%.

The Little Phone That Could Ch-Ch-Chroot
2019Co-Authors: Whitter-jones Jack, Evans MathewAbstract:Security testing has been a career path that many are beginning to take. In doing so, security testing can hit the realms of many different types of engagements, ranging from web, infrastructure and social engineering. With the risk of sabotage, corporate espionage it has been seen that many organisations are beginning to develop a tactical capability. In doing so, the term 'Red Team' has been coined to market such engagements. Red Teaming is the method of having almost free reign towards a target. By doing such an engagement a target will be able to fully understand the breadth of vulnerabilities facing their organisation. However, Red Teaming can be an expensive and resource intensive task. Through this paper, it is discussed that it is possible to make a covert disposable phone to help aide Red Teamer's with the Reconnaissance Phase without drawing attention to themselves within a day to day task.Comment: Presented At BSides London 201
