as well as extensive privacy issues (e.g., tracking) that are now pervasive on the
Web. The chapter includes a completely new section on Web privacy, more exten- sive discussions of modern content delivery technology (e.g., content delivery net- works), and an expanded discussion on peer-to-peer networks. The section on the
evolution of the Internet has also been edited to reflect trends towards distributed
cloud services. Chapter 8 has been completely overhauled. In previous editions, the focus of
the security chapter was almost exclusively on information security by means of
cryptography. However, cryptography is only one aspect of network security and if
we look at security incidents in practice, it is generally not the aspect where the
problems are. To remedy this, we added new content on security principles, funda- mental attack techniques, defenses, and a wide range of systems-related security
issues. Moreover, we updated the existing sections by dropping some encryption
techniques that are now obsolete and introducing more modern versions of proto- cols and standards. Chapter 9 contains a renewed list of suggested readings and a comprehensive
bibliography. In addition,
