Public sector organizations are facing an escalating challenge with the increasing volume and complexity of cyberattacks, which disrupt essential public services and jeopardize citizen data and privacy. Effective cybersecurity management has become an urgent necessity. To combat these threats comprehensively, the active involvement of all functional areas is crucial, necessitating a heightened holistic cybersecurity awareness among tactical and operational teams responsible for implementing security measures. Public entities face various challenges in maintaining this awareness, including difficulties in building a skilled cybersecurity workforce, coordinating mixed internal and external teams, and adapting to the outsourcing trend, which includes cybersecurity operations centers (CyberSOCs). Our research began with an extensive literature analysis to expand our insights derived from previous works, followed by a Spanish case study in collaboration with a digitization-focused public organization. The study revealed common features shared by public organizations globally. Collaborating with this public entity, we developed strategies tailored to its characteristics and transferrable to other public organizations. As a result, we propose the "Wide-Scope CyberSOC" as an innovative outsourced solution to enhance holistic awareness among the cross-functional cybersecurity team and facilitate comprehensive cybersecurity adoption within public organizations. We have also documented essential requirements for public entities when contracting Wide-Scope CyberSOC services to ensure alignment with their specific needs, accompanied by a management framework for seamless operation.

With the continuous development of mobile communications over the past few years, the achievement of an efficient IP mobility management has revealed as one of the major challenges in next-generation wireless networks. For this reason, the Internet Engineering Task Force developed various centralized mobility protocols where all intelligence is concentrated in one end-point system. However, centralized mobility solutions are prone to several problems such as signaling overhead or scalability issues, among others. In order to overcome these limitations, a new approach, called Distributed Mobility Management (DMM), is currently being considered. In this paper, an analytical cost model and experimental evaluation are developed for evaluating the performance of the DMM implementations. Furthermore, a new approach called Tunneling Extension to Distributed Mobility Management (TE-DMM) is described. TE-DMM proposes a modification to the distributed existing solutions in order to reduce the signaling overhead and consequently improve the control plane. Experimental results have been obtained from a real testbed in which TE-DMM has been implemented. Both the analytical evaluation and the experimental results show that our distributed solution optimizes the signaling processing as well as the packet loss during handovers.

Mobility management and quality of service (QoS) are two of the most important goals in the present and future development of wireless networks. These tasks involve not only the wireless domain but also the access network that interconnects mobile devices with the Internet. This emerging topic is known as fixed mobile convergence. The intention of this convergence is the integration and creation of a unified infrastructure from fixed and wireless mobile networks. In this converged infrastructure, users can move across networks and access services seamlessly. In this paper, we present a study on recent advances and open research issues on mobility protocols in conjunction with multi-protocol label switching (MPLS)-based access networks. Various mobile management protocols and their interaction with the access network are briefly introduced. A new architecture called integrated proxy mobile MPLS transport profile is also outlined to provide the highest integration level, QoS and high rates of mobility to achieve fixed mobile convergence.

The emergence of new kinds of applications and technologies (e.g., data-intensive applications, server virtualization, and big data technology) has led to a higher utilization of network resources. These services imply increased bandwidth consumption and unexpected congestions, especially in backbones. In this article, a novel proposal is studied with the aim of improving the performance of prioritized forwarding equivalence classes in congested Multiprotocol Label Switching Transport Profile (MPLS-TP) domains. The congestion impact on those QoS-aware services that require high reliability and low delay is analyzed. A new policy has been implemented on MPLS-TP, which is a technology that provides QoS by means of flow differentiation in the Internet backbones. The proposal is known as Gossip-based local recovery policy and is offered as an operation, administration, and management function to allow local recovery of lost traffic for MPLS-TP privileged forwarding equivalence classes. In order to fulfill the requirements for implementation on MPLS-TP, a minimum set of extensions to resource reservation protocol traffic engineering has also been proposed to provide self-management capable routes. Finally, we have carried out a performance improvement measurement by means of an analytical model and simulations. Copyright © 2014 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

The new context of the European Space of Higher Education and the current social environment marked by new technologies implies that new Telecommunication Engineers must be trained not only in technical knowledge but also in the professional skills that they must use in their professional lives. Some learning methodologies, such as Project-Based Learning help develop these skills. This paper presents projects developed in order to teach and assess different skills. The methods used change depending on the year of the academic program. The projects have been designed to focus on "process skills": The ability to work in a multi-disciplinary team, understanding of both professional and ethical responsibility and the ability to communicate effectively. The projects have been assessed through multi-source feedback combined with the use of rubrics to facilitate the evaluation. According to the results, most of the objectives have been achieved. Student satisfaction is very high, as the survey results demonstrate. [ABSTRACT FROM AUTHOR]
