Computer and Information Security

This book explains claims-based identity how to use it in the context of some commonly occurring scenarios.

Written for computer and Internet savvy "tweens" and teens, this book is also a useful resource for the adults they rely on.

This book is packed with twice the pages and offers even more practical information for UNIX users and administrators. It covers features of many types of UNIX systems, including SunOS, Solaris, BSDI, AIX, HP-UX, Digital UNIX, Linux, and others. The first edition was practical, entertaining, and full of useful scripts, tips, and warnings. This edition is all those things -- and more.

If you are a network administrator, you're under a lot of pressure to ensure that mission-critical systems are completely safe from malicious code, buffer overflows, stealth port scans, SMB probes, OS fingerprinting attempts, CGI attacks, and other network intruders. Designing a reliable way to detect intruders before they get in is an essential - but often overwhelming--challenge.

SpamAssassin by Alan Schwartz, is the only published resource devoted to SpamAssassin and how to integrate it effectively into your networks. This clear, concise guide clarifies the installation, configuration, and use of the SpamAssassin spam-checking system (versions 2.63 and 3.0) for Unix system administrators using the Postfix, Sendmail, Exim, or qmail mail servers, helping administrators make the right integration decision for their particular environments.

Updated annually, this book is the most comprehensive and up-to-date reference available on information security and assurance. Bringing together the knowledge, skills, techniques, and tools required of IT security professionals, it facilitates the up-to-date understanding required to stay one step ahead of evolving threats, standards, and regulations.

In The Coming Swarm, rising star Molly Sauter examines the history, development, theory, and practice of Distributed Denial of Service (DDoS) actions as a tactic of political activism. The internet is a vital arena of communication, self expression, and interpersonal organizing. When there is a message to convey, words to get out, or people to unify, many will turn to the internet as a theater for that activity.

Web application security may seem like a complex, daunting task. This book is a quick guide to understanding how to make your website secure. It surveys the best steps for establishing a regular program to quickly find vulnerabilities in your site with a web application scanner.

This document is aimed at Security and IT practitioners (especially architects) in end-user organisations who are responsible for implementing an enterprise-wide Identity and Access Management (IAM) system. It is neither a conceptual treatment of Identity (for which we would refer the reader to Kim Cameron's excellent work on the Laws of Identity) nor a detailed technical manual on a particular product. It describes a pragmatic and cost-effective architectural approach to implementing IAM within an organisation, based on the experience of the authors.

Every day, more users access services and electronically transmit information which is usually disseminated over insecure networks and processed by websites and databases, which lack proper security protection mechanisms and tools. This may have an impact on both the users' trust as well as the reputation of the system's stakeholders. Designing and implementing security enhanced systems is of vital importance.

In the era of Internet of Things (IoT) and with the explosive worldwide growth of electronic data volume, and associated need of processing, analysis, and storage of such humongous volume of data, several new challenges are faced in protecting privacy of sensitive data and securing systems by designing novel schemes for secure authentication, integrity protection, encryption, and non-repudiation. Lightweight symmetric key cryptography and adaptive network security algorithms are in demand for mitigating these challenges.

Computer security touches every part of our daily lives from our computers and connected devices to the wireless signals around us. Breaches have real and immediate financial, privacy, and safety consequences.

Security Service Edge (SSE) is described by Gartner as the security stack of services within a SASE architecture. SSE is fast, easy to use, and secures your business wherever your people and data go.

This book is an introduction to the applied topic of computer security. Readers will learn ways of preventing, identifying, understanding, and recovering from attacks against computer systems.
