Available in PDF, EPUB and Kindle. Book excerpt: The first comprehensive guide to the design and implementation of security in 5G wireless networks and devices Security models for 3G and 4G networks based on Universal SIM cards worked very well. But they are not fully applicable to the unique security requirements of 5G networks. 5G will face additional challenges due to increased user privacy concerns, new trust and service models and requirements to support IoT and mission-critical applications. While multiple books already exist on 5G, this is the first to focus exclusively on security for the emerging 5G ecosystem. 5G networks are not only expected to be faster, but provide a backbone for many new services, such as IoT and the Industrial Internet. Those services will provide connectivity for everything from autonomous cars and UAVs to remote health monitoring through body-attached sensors, smart logistics through item tracking to remote diagnostics and preventive maintenance of equipment. Most services will be integrated with Cloud computing and novel concepts, such as mobile edge computing, which will require smooth and transparent communications between user devices, data centers and operator networks. Featuring contributions from an international team of experts at the forefront of 5G system design and security, this book: Provides priceless insights into the current and future threats to mobile networks and mechanisms to protect it Covers critical lifecycle functions and stages of 5G security and how to build an effective security architecture for 5G based mobile networks Addresses mobile network security based on network-centricity, device-centricity, information-centricity and people-centricity views Explores security considerations for all relative stakeholders of mobile networks, including mobile network operators, mobile network virtual operators, mobile users, wireless users, Internet-of things, and cybersecurity experts Providing a comprehensive guide to state-of-the-art in 5G security theory and practice, A Comprehensive Guide to 5G Security is an important working resource for researchers, engineers and business professionals working on 5G development and deployment.

Download or read book Software Networks written by Guy Pujolle and published by John Wiley & Sons. This book was released on 2015-08-31 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this book is to describe new concepts for Internet next generation. This architecture is based on virtual networking using Cloud and datacenters facilities. Main problems concern 1) the placement of virtual resources for opening a new network on the fly, and 2) the urbanisation of virtual resource implemented on physical network equipment. This architecture deals with mechanisms capable of controlling automatically the placement of all virtual resources within the physical network. In this book, we describe how to create and delete virtual networks on the fly. Indeed, the system is able to create any new network with any kind of resource (e.g., virtual switch, virtual routers, virtual LSRs, virtual optical path, virtual firewall, virtual SIP-based servers, virtual devices, virtual servers, virtual access points, and so on). We will show how this architecture is compatible with new advances in SDN (Software Defined Networking), new high-speed transport protocol like TRILL (Transparent Interconnection of Lots of Links) and LISP (Locator/Identifier Separation Protocol), NGN, IMS, Wi-Fi new generation, and 4G/5G networks. Finally, we introduce the Cloud of security and the virtualisation of secure elements (smartcard) that should definitely transform how to secure the Internet.

Download or read book 5G Cyber Risks and Mitigation written by Sabhyata Soni and published by CRC Press. This book was released on 2023-04-13 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: 5G technology is the next step in the evolution of wireless communication. It offers faster speeds and more bandwidth than 4G. One of the biggest differences between 4G and 5G is that 5G will be used for a wider range of applications. This makes it ideal for applications such as autonomous vehicles, smart cities, and the Internet of Things (IoT). This means that there will be more devices connected to 5G networks, making them more vulnerable to cyber attacks. However, 5G also introduces new cyber risks that need to be addressed. In addition, 5G networks are expected to be much more complex, making them harder to secure. 5G networks will use new technologies that could make them more vulnerable to attacks. These technologies include massive multiple input, multiple output (MIMO), which uses more antennas than traditional cellular networks, and millimeter wave (mmWave), which uses higher frequencies than traditional cellular networks. These new technologies could make it easier for attackers to intercept data or disrupt service. To address these concerns, security measures must be implemented throughout the network. Security mechanisms must be included in the design of 5G networks and must be updated as new threats are identified. Moreover, to address these risks, 5G security standards need to be developed and implemented. These standards should include measures to protect against Denial of Service (DoS) attacks, malware infections, and other threats. Fortunately, Artificial Intelligence (AI) can play a key role in mitigating these risks. With so many interconnected devices, it can be difficult to identify and isolate malicious traffic. AI can help by identifying patterns in data that would otherwise be undetectable to humans. 6G technology is still in the early developmental stages, but security experts are already voicing concerns about the potential challenges that could arise with this next generation of mobile connectivity. Experts are already working on a roadmap for 6G deployment, and they are confident that these and other challenges can be overcome.
