Summary : If you think computer security has improved in recent years, The Myths of Security will shake you out of your complacency. Longtime security professional John Viega, formerly Chief Security Architect at McAfee, reports on the sorry state of the industry, and offers concrete suggestions for professionals and individuals confronting the issue. Why is security so bad? With many more people online than just a few years ago, there are more attackers -- and they're truly motivated. Attacks are sophisticated, subtle, and harder to detect than ever. But, as Viega notes, few people take the time to understand the situation and protect themselves accordingly. This book tells you: Why it's easier for bad guys to "own" your computer than you think Why anti-virus software doesn't work well -- and one simple way to fix it Whether Apple OS X is more secure than Windows What Windows needs to do better How to make strong authentication pervasive Why patch management is so bad Whether there's anything you can do about identity theft Five easy steps for fixing application security, and more Provocative, insightful, and always controversial, The Myths of Security not only addresses IT professionals who deal with security issues, but also speaks to Mac and PC users who spend time online.

Summary : "Operating systems provide the fundamental mechanisms for securing computer processing. Since the 1960s, operating systems designers have explored how to build"secure" operating systems - operating systems whose mechanisms protect the system against a motivated adversary. Recently, the importance of ensuring such security has become a mainstream issue for all operating systems. In this book, we examine past research that outlines the requirements for a secure operating system and research that implements example systems that aim for such requirements. For system designs that aimed to satisfy these requirements,we see that the complexity of software systems often results in implementation challenges that we are still exploring to this day. However, if a system design does not aim for achieving the secure operating system requirements, then its security features fail to protect the system in a myriad of ways. We also study systems that have been retro-fit with secure operating system features after an initial deployment. In all cases, the conflict between function on one hand and security on the other leads to difficult choices and the potential for unwise compromises. From this book, we hope that systems designers and implementers will learn the requirements for operating systems that effectively enforce security and will better understand how to manage the balance between function and security."--BOOK JACKET.

Summary : Examining the layers of meaning encoded in software and the rhetoric surrounding it, this book offers a much-needed perspective on the intersections between software, morality, and politics. In software development culture, evangelism typically denotes a rhetorical practice that aims to convert software developers, as well as non-technical lay users, from one platform to another (e.g., from the operating system Microsoft Windows to Linux). This book argues that software evangelism, like its religious counterpart, must also be understood as constructing moral and political values that extend well beyond the boundaries of the development culture. Unlike previous studies that locate such values in the effects of code in-use or in certain types of code like free and open source (FOSS) software, Maher argues that all code is meaningful beyond its technical, executable functions. To facilitate this analysis, this study builds a theory of evangelism and illustrates this theory at work in the proprietary software industry and FOSS communities. As an example of political liberalism at work at the level of code, these evangelical rhetorics of software construct competing conceptions of what is good that fall within a shared belief in what is just. Maher illustrates how these beliefs in goodness and justice do not always execute in replicable ways, as the different ways of decoding software evangelisms in the contexts of Brazil and China reveal. Demonstrating how software evangelisms exert a transformative force on the world, one comparable in significance to code itself, this book highlights the importance of rhetoric in even the most seemingly a-rhetorical of technical endeavors and foregrounds the crucial need for rhetorical literacy in the digital age.

Summary : Enhance file system security and learn about network attack, security tools and different versions of Linux build. Key Features Hands-on recipes to create and administer a secure Linux system Enhance file system security and local and remote user authentication Use various security tools and different versions of Linux for different tasks Book Description Over the last few years, system security has gained a lot of momentum and software professionals are focusing heavily on it. Linux is often treated as a highly secure operating system. However, the reality is that Linux has its share of security flaws, and these security flaws allow attackers to get into your system and modify or even destroy your important data. But there’s no need to panic, since there are various mechanisms by which these flaws can be removed, and this book will help you learn about different types of Linux security to create a more secure Linux system. With a step-by-step recipe approach, the book starts by introducing you to various threats to Linux systems. Then, this book will walk you through customizing the Linux kernel and securing local files. Next, you will move on to managing user authentication both locally and remotely and mitigating network attacks. Later, you will learn about application security and kernel vulnerabilities. You will also learn about patching Bash vulnerability, packet filtering, handling incidents, and monitoring system logs. Finally, you will learn about auditing using system services and performing vulnerability scanning on Linux. By the end of this book, you will be able to secure your Linux systems and create a robust environment. What you will learn Learn about vulnerabilities and exploits in relation to Linux systems Configure and build a secure kernel and test it Learn about file permissions and how to securely modify files Authenticate users remotely and securely copy files on remote systems Review different network security methods and tools Perform vulnerability scanning on Linux machines using tools Learn about malware scanning and read through logs Who this book is for This book is intended for all those Linux users who already have knowledge of Linux file systems and administration. You should be familiar with basic Linux commands. Understanding information security and its risks to a Linux system is also helpful in understanding the recipes more easily.
