Linux Security Fundamentals

Linux Security Fundamentals provides basic foundational concepts of securing a Linux environment. The focus is the digital self-defense of an individual user. This includes a general understanding of major threats against individual computing systems, networks, services and identity as well as approaches to prevent and mitigate them. This book is useful for anyone considering a career as a Linux administrator or for those administrators who need to learn more about Linux security issues. Topics include: • Security Concepts • Encryption • Node, Device and Storage Security • Network and Service Security • Identity and Privacy Readers will also have access to Sybex's superior online interactive learning environment and test bank, including chapter tests, a practice exam, electronic flashcards, a glossary of key terms.

This book includes coverage of the new and updated security features of Linux, and teaches the reader security fundamentals and how to think about security before they even install the software. This text is designed to provide a basic guide to resolving security involved in the use of Linux in workstation, small server, or small network environments.

This is the first of two books serving as an expanded and up-dated version of Windows Server 2003 Security Infrastructures for Windows 2003 Server R2 and SP1 & SP2. The authors choose to encompass this material within two books in order to illustrate the intricacies of the different paths used to secure MS Windows server networks. Since its release in 2003 the Microsoft Exchange server has had two important updates, SP1 and SP2. SP1, allows users to increase their security, reliability and simplify the administration of the program. Within SP1, Microsoft has implemented R2 which improves identity and access management across security-related boundaries. R2 also improves branch office server management and increases the efficiency of storage setup and management. The second update, SP2 minimizes spam, pop-ups and unwanted downloads. These two updated have added an enormous amount of programming security to the server software. * Covers all SP1 and SP2 updates * Details strategies for patch management * Provides key techniques to maintain security application upgrades and updates

Learn how to attack and defend the world’s most popular web server platform Linux Server Security: Hack and Defend presents a detailed guide for experienced admins, aspiring hackers and other IT professionals seeking a more advanced understanding of Linux security. Written by a 20-year veteran of Linux server deployment this book provides the insight of experience along with highly practical instruction. The topics range from the theory of past, current, and future attacks, to the mitigation of a variety of online attacks, all the way to empowering you to perform numerous malicious attacks yourself (in the hope that you will learn how to defend against them). By increasing your understanding of a hacker’s tools and mindset you're less likely to be confronted by the all-too-common reality faced by many admins these days: someone else has control of your systems. Master hacking tools and launch sophisticated attacks: perform SQL injections, deploy multiple server exploits and crack complex passwords. Defend systems and networks: make your servers invisible, be confident of your security with penetration testing and repel unwelcome attackers. Increase your background knowledge of attacks on systems and networks and improve all-important practical skills required to secure any Linux server. The techniques presented apply to almost all Linux distributions including the many Debian and Red Hat derivatives and some other Unix-type systems. Further your career with this intriguing, deeply insightful, must-have technical book. Diverse, broadly-applicable and hands-on practical, Linux Server Security: Hack and Defend is an essential resource which will sit proudly on any techie's bookshelf.

An easy to understand guide of the most commonly faced security threats any computer user is likely to come across via email, social media and online shopping. This is not aimed at people studying Internet Security or CISSP, but general users, though still helpful to both. Antivirus software is now incredibly advanced, but the problem of viruses is worse than ever! This is because many viruses trick the user into installing them. The same way that the most sophisticated alarm system and door security is not much use if you open the door from the inside to let someone in. This book explains in easy to understand terms, why you cannot just rely on antivirus, but also need to be aware of the various scams and tricks used by criminals.

ALL YOU NEED TO KNOW TO SECURE LINUX SYSTEMS, NETWORKS, APPLICATIONS, AND DATA–IN ONE BOOK From the basics to advanced techniques: no Linux security experience necessary Realistic examples & step-by-step activities: practice hands-on without costly equipment The perfect introduction to Linux-based security for all students and IT professionals Linux distributions are widely used to support mission-critical applications and manage crucial data. But safeguarding modern Linux systems is complex, and many Linux books have inadequate or outdated security coverage. Linux Essentials for Cybersecurity is your complete solution. Leading Linux certification and security experts William “Bo” Rothwell and Dr. Denise Kinsey introduce Linux with the primary goal of enforcing and troubleshooting security. Their practical approach will help you protect systems, even if one or more layers are penetrated. First, you’ll learn how to install Linux to achieve optimal security upfront, even if you have no Linux experience. Next, you’ll master best practices for securely administering accounts, devices, services, processes, data, and networks. Then, you’ll master powerful tools and automated scripting techniques for footprinting, penetration testing, threat detection, logging, auditing, software management, and more. To help you earn certification and demonstrate skills, this guide covers many key topics on CompTIA Linux+ and LPIC-1 exams. Everything is organized clearly and logically for easy understanding, effective classroom use, and rapid on-the-job training.
