This book provides a concise yet comprehensive overview of computer and Internet security, suitable for a one-term introductory course for junior/senior undergrad or first-year graduate students. It is also suitable for self-study by anyone seeking a solid footing in security – including software developers and computing professionals, technical managers and government staff. An overriding focus is on brevity, without sacrificing breadth of core topics or technical detail within them. The aim is to enable a broad understanding in roughly 350 pages. Further prioritization is supported by designating as optional selected content within this. Fundamental academic concepts are reinforced by specifics and examples, and related to applied problems and real-world incidents. The first chapter provides a gentle overview and 20 design principles for security. The ten chapters that follow provide a framework for understanding computer and Internet security. They regularly refer back to the principles, with supporting examples. These principles are the conceptual counterparts of security-related error patterns that have been recurring in software and system designs for over 50 years. The book is “elementary” in that it assumes no background in security, but unlike “soft” high-level texts it does not avoid low-level details, instead it selectively dives into fine points for exemplary topics to concretely illustrate concepts and principles. The book is rigorous in the sense of being technically sound, but avoids both mathematical proofs and lengthy source-code examples that typically make books inaccessible to general audiences. Knowledge of elementary operating system and networking concepts is helpful, but review sections summarize the essential background. For graduate students, inline exercises and supplemental references provided in per-chapter endnotes provide a bridge to further topics and a springboard to the research literature; for those in industry and government, pointers are provided to helpful surveys and relevant standards, e.g., documents from the Internet Engineering Task Force (IETF), and the U.S. National Institute of Standards and Technology.

Cybercrime is increasingly in the news on both an individual and national level--from the stolen identities and personal information of millions of Americans to the infiltration of our national security networks allowing access to both economic and trade secrets. In Cyberphobia, Edward Lucas unpacks this shadowy but metastasizing problem confronting our security. The uncomfortable truth is that we do not take cybersecurity seriously enough. When it comes to the internet, it might as well be the Wild West. Standards of securing our computers and other internet-connected technology are diverse, but just like the rules of the road meant to protect both individual drivers and everyone else driving alongside them, weak cybersecurity on the computers and internet systems near us put everyone at risk. Lucas sounds a necessary alarm on behalf of cybersecurity and prescribes immediate and bold solutions to this grave threat.

"Internet Security: How to Defend Against Attackers on the Web, Second Edition provides a comprehensive explanation of the evolutionary changes that have occurred in computing, communications, and social networking and discusses how to secure systems against all the risks, threats, and vulnerabilities associated with Web-enabled applications accessible via the internet"--

When Practical Unix Security was first published more than a decade ago, it became an instant classic. Crammed with information about host security, it saved many a Unix system administrator from disaster. The second edition added much-needed Internet security coverage and doubled the size of the original volume. The third edition is a comprehensive update of this very popular book - a companion for the Unix/Linux system administrator who needs to secure his or her organization's system, networks, and web presence in an increasingly hostile world.Focusing on the four most popular Unix variants today--Solaris, Mac OS X, Linux, and FreeBSD--this book contains new information on PAM (Pluggable Authentication Modules), LDAP, SMB/Samba, anti-theft technologies, embedded systems, wireless and laptop issues, forensics, intrusion detection, chroot jails, telephone scanners and firewalls, virtual and cryptographic filesystems, WebNFS, kernel security levels, outsourcing, legal issues, new Internet protocols and cryptographic algorithms, and much more.Practical Unix & Internet Security consists of six parts: Computer security basics: introduction to security problems and solutions, Unix history and lineage, and the importance of security policies as a basic element of system security. Security building blocks: fundamentals of Unix passwords, users, groups, the Unix filesystem, cryptography, physical security, and personnel security. Network security: a detailed look at modem and dialup security, TCP/IP, securing individual network services, Sun's RPC, various host and network authentication systems (e.g., NIS, NIS+, and Kerberos), NFS and other filesystems, and the importance of secure programming. Secure operations: keeping up to date in today's changing security world, backups, defending against attacks, performing integrity management, and auditing. Handling security incidents: discovering a break-in, dealing with programmed threats and denial of service attacks, and legal aspects of computer security. Appendixes: a comprehensive security checklist and a detailed bibliography of paper and electronic references for further reading and research. Packed with 1000 pages of helpful text, scripts, checklists, tips, and warnings, this third edition remains the definitive reference for Unix administrators and anyone who cares about protecting their systems and data from today's threats.

Internet Security incorporates not only the technology needed to support a solid security strategy but also those policies and processes that must be incorporated in order for that strategy to work.New methods of breaking into corporate networks are resulting in major losses. This book provides the latest information on how to guard against attacks and informs the IT manager of the products that can detect and prevent break-ins. Crucial concepts such as authentication and encryption are explained, enabling the reader to understand when and where these technologies will be useful. Due to the authors' experiences in helping corporations develop secure networks, they are able to include the newest methods for protecting corporate data.·Shield data from both the internal and external intruder·Discover products that can detect and prevent these break-ins ·Protect against major losses with the latest incident handling procedures for detecting and recovering data from new viruses·Get details of a full security business review from performing the security risk analysis to justifying security expenditures based on your company's business needs

Nothing people do online is ever completely private or anonymous. With each technological advance in the connectivity of the internet comes additional opportunities for cybercriminals to have immediate access to an individual's life. This volume explains how personal and private information is at risk for theft and what people can do to keep it secure from hackers who want to steal information, money, and even their identity. Teens discover not only what tools and strategies these hackers are using to get to their information but what steps they can take to stay safe. Readers will understand password protection and learn how to use Wi-Fi safely.
