This timely and compelling book presents a broad study of all key cyber security issues of the highest interest to government and business as well as their implications. This comprehensive work focuses on the current state of play regarding cyber security threats to government and business, which are imposing unprecedented costs and disruption. At the same time, it aggressively takes a forward-looking approach to such emerging industries as automobiles and appliances, the operations of which are becoming more closely tied to the internet. Revolutionary developments will have security implications unforeseen by manufacturers, and the authors explore these in detail, drawing on lessons from overseas as well as the United States to show how nations and businesses can combat these threats. The book's first section describes existing threats and their consequences. The second section identifies newer cyber challenges across an even broader spectrum, including the internet of things. The concluding section looks at policies and practices in the United States, United Kingdom, and elsewhere that offer ways to mitigate threats to cyber security. Written in a nontechnical, accessible manner, the book will appeal to a diverse audience of policymakers, business leaders, cyber security experts, and interested general readers.
Organizations of all sizes struggle to secure their data in a constantly evolving digital landscape. Expanding digital footprints and the rapid expansion of cloud strategies arising from the COVID-19 pandemic increase an organization’s attack surface. When combined with limited resources caused by the cybersecurity skills gap, securing small and mid-sized business IT infrastructures becomes more complicated. With limited staffing and budgetary restrictions, small businesses need to create cost-effective, security-driven programs that protect data while also meeting increasingly stringent compliance requirements. This book bridges the gap between complex technical language and business objectives to create a security-first review of the security and compliance landscapes. Starting from the premise that “with security comes compliance,” this book starts by defining “security-first” and then walking readers through the process of creating a holistic security and compliance program. Looking at security and privacy through the lens of zero trust, this overview of regulations and industry standards provides both background about and implications drawn from modern security practices. Rather than focusing solely on individual cybersecurity frameworks, this book offers insights into best practices based on the commonalities between regulations and industry standards, highlighting some of the primary differences to show the nuances. Woven throughout are practical examples of solutions that enable small and mid-sized businesses to create “cybersustainable” security-focused policies, processes, and controls that protect today’s future for tomorrow’s digital ecosystem.
Network programming has always been a demanding task. With full-featured and well documented libraries all the way up the stack, Python makes network programming the enjoyable experience it should be. Starting with a walkthrough of today's major networking protocols, with this book you'll learn how to employ Python for network programming, how to request and retrieve web resources, and how to extract data in major formats over the Web. You'll utilize Python for e-mailing using different protocols and you'll interact with remote systems and IP and DNS networking. As the book progresses, socket programming will be covered, followed by how to design servers and the pros and cons of multithreaded and event-driven architectures. You'll develop practical client-side applications, including web API clients, e-mail clients, SSH, and FTP. These applications will also be implemented through existing web application frameworks.
Become more fluent in Python—learn strategies and techniques for smart and high-performance Python programming About This Book Write smarter, bug-free, high performance code with minimal effort Uncover the best tools and options available to Python developers today Deploy decorators, design patters, and various optimization techniques to use Python 3.5 effectively Who This Book Is For If you are a Python developer and you think that you don't know everything about the language yet, then this is the book for you. We will unlock the mysteries and re-introduce you to the hidden features of Python to write efficient programs, making optimal use of the language. What You Will Learn Manipulate object creation processes for instances, classes, and functions Use the best possible language constructs to write data structures with super speed and maintainability Make efficient use of design patterns to decrease development time and make your code more maintainable Write better test cases with an improved understanding of the testing framework of Python and unittests, and discover how to develop new functionalities in it Write fully-optimized code with the Python language by profiling, compiling C modules, and more Unlock asynchronous programming to build efficient and scalable applications In Detail Python is a versatile programming language that can be used for a wide range of technical tasks—computation, statistics, data analysis, game development, and more. Though Python is easy to learn, it's range of features means there are many aspects of it that even experienced Python developers don't know about. Even if you're confident with the basics, its logic and syntax, by digging deeper you can work much more effectively with Python – and get more from the language. Python Unlocked walks you through the most effective techniques and best practices for high performance Python programming - showing you how to make the most of the Python language. You'll get to know objects and functions inside and out, and will learn how to use them to your advantage in your programming projects. You will also find out how to work with a range of design patterns including abstract factory, singleton, strategy pattern, all of which will help make programming with Python much more efficient. Finally, as the process of writing a program is never complete without testing it, you will learn to test threaded applications and run parallel tests. If you want the edge when it comes to Python, use this book to unlock the secrets of smarter Python programming. Style and approach This is book had been created to help you to “unlock” the best ways to tackle the challenges and performance bottlenecks that many Python developers face today. The keys are supported with program examples to help you understand the concepts better and see them in action.
