SECURING and EVOLVING ARCHITECTURES 5G initiates a period of technological evolution where the benefits transcend faster data download speeds and enable services that will change the way we all live and consume technology. Leveraging 5G's openness, a new developer ecosystem is building breakthrough services that billions of people will consume, delivering immense value to enterprises and subscribers alike. For 5G to achieve its potential, organizations must embrace multi-layered security that goes far beyond 3GPP specifications. Now, leading security architect Pramod Nair helps network professionals climb the steep learning curve associated with securing 5G, fully understand its threat surfaces, systematically mitigate its risks, and maximize the value of their security investments. This coherent, pragmatic, and vendor-agnostic guide will help you plan for security from the outset, make better choices throughout the lifecycle, and develop the mindset needed to secure new generations of networks. You'll find all you need: from high-level 5G security concepts to in-depth coverage of specific security controls, end-to-end architectural guidance, 5G security use cases, and cutting-edge "quantum proofing." Throughout, practical examples and real-life scenarios help you apply Nair's insights---whether you're a service provider, an enterprise, an industry vertical, a startup, a cybersecurity vendor, a systems integrator, or even in a defense environment. Securing 5G and Evolving Architectures is for technical and management audiences at all levels of 5G experience---from enterprise and security architects to network engineers, cloud computing and data center professionals, to CSO and CTO teams.
