Computer Networks

A potent exploration of the power of blockchains to reshape the future of the Internet--and how that affects us all--from highly influential entrepreneur and technology investor Chris Dixon The Internet of today is a far cry from its early promise of a decentralized, democratic network of creativity and innovation. In the past decade, the Internet has fallen under the control of a tiny group of massive companies like Apple, Google, and Facebook. In Read Write Own, tech visionary Chris Dixon argues that the dream of an open network for fostering creativity and entrepreneurship doesn't have to die, and that in fact it can, and must, be saved with blockchain networks, which he vitally separates from the currency-based speculation that it is unfortunately lumped together with--a distinction he calls "The Computer vs The Casino". With lucid and compelling prose--and drawing from his first-hand observations, mental models, and experiences over a 25-year career in the Internet industry--Dixon

A real-life technological thriller about a band of eccentric misfits taking on the biggest cybersecurity threats of our time.Scattered across the world, an elite team of computer experts are working tirelessly on your behalf. If you’ve been lucky (or careful), you’ve probably never heard of them. But if you’ve downloaded a fraudulent email attachment or worked for a hospital or municipal government, chances are you’re familiar with the team’s sworn enemy: ransomware, and the shadowy networks of hackers and criminal gangs who use it to extort money from those whose computers they infect.The Ransomware Hunting Team is the incredible true story of a ragtag band of “white hat”―or good-guy―hackers who use their extraordinary skills to help victims of this fast-proliferating form of cybercrime. Working in their free time from bedrooms and back offices, they offer their services pro bono to people whom the FBI and other law enforcement agencies are unwilling, or more often powerless, to help.

One of the most coveted tools in a spy's arsenal, a zero day has the power to tap into any iPhone, dismantle safety controls at a chemical plant and shut down the power in an entire nation - just ask the Ukraine. Zero days are the blood diamonds of the security trade, pursued by nation states, defense contractors, cybercriminals, and security defenders alike.In this market, governments aren't regulators; they are clients - payi

Cybersecurity is a leading national problem for which the market may fail to produce a solution. The ultimate source of the problem is that computer owners lack adequate incentives to invest in security because they bear fully the costs of their security precautions but share the benefits with their network partners. In a world of positive transaction costs, individuals often select less than optimal security levels. The problem is compounded because the insecure networks extend far beyond the regulatory jurisdiction of any one nation or even coalition of nations. Originally published in 2006, this book brings together the views of leading law and economics scholars on the nature of the cybersecurity problem and possible solutions to it. Many of these solutions are market based, but they need some help, either from government or industry groups, or both. Indeed, the cybersecurity problem prefigures a host of twenty-first-century problems created by information technology and the global

The rapidly expanding area of algebraic graph theory uses two different branches of algebra to explore various aspects of graph theory: linear algebra (for spectral theory) and group theory (for studying graph symmetry). These areas have links with other areas of mathematics, such as logic and harmonic analysis, and are increasingly being used in such areas as computer networks where symmetry is an important feature. Other books cover portions of this material, but this book is unusual in covering both of these aspects and there are no other books with such a wide scope. Peter J. Cameron, internationally recognized for his substantial contributions to the area, served as academic consultant for this volume, and the result is ten expository chapters written by acknowledged international experts in the field. Their well-written contributions have been carefully edited to enhance readability and to standardize the chapter structure, terminology and notation throughout the book. To help th

The theory of random graphs began in the late 1950s in several papers by Erdos and Renyi. In the late twentieth century, the notion of six degrees of separation, meaning that any two people on the planet can be connected by a short chain of people who know each other, inspired Strogatz and Watts to define the small world random graph in which each site is connected to k close neighbors, but also has long-range connections. At a similar time, it was observed in human social and sexual networks and on the Internet that the number of neighbors of an individual or computer has a power law distribution. This inspired Barabasi and Albert to define the preferential attachment model, which has these properties. These two papers have led to an explosion of research. The purpose of this book is to use a wide variety of mathematical argument to obtain insights into the properties of these graphs. A unique feature is the interest in the dynamics of process taking place on the graph in addition to

Many machine learning algorithms require real-valued feature vectors of data instances as inputs. By projecting data into vector spaces, representation learning techniques have achieved promising performance in many areas such as computer vision and natural language processing. There is also a need to learn representations for discrete relational data, namely networks or graphs. Network Embedding (NE) aims at learning vector representations for each node or vertex in a network to encode the topologic structure. Due to its convincing performance and efficiency, NE has been widely applied in many network applications such as node classification and link prediction.This book provides a comprehensive introduction to the basic concepts, models, and applications of network representation learning (NRL). The book starts with an introduction to the background and rising of network embeddings as a general overview for readers. Then it introduces the development of NE techniques by presenting se
