Book Description
This book provides a detailed analysis of UNIX security facilities. Designed for system administrators and security managers, this guide covers TCP/IP, UUCP, and OSI networks and their security; progresses from file system security to account security to process security to network security; describes relevant system and library calls, and indicates how they may be used to interface with the security sub-system in the kernel; special chapter included on Trusted Systems; provides detailed descriptions of the various standards applied to UNIX security; provides information on UNIX viruses and Trojan Horses, and their prevention and detection; and also includes an Appendix on the Internet Worm.

Book Description
There are many objectives and goals to be considered when securing a operating system. When configuring Unix operating system security, consider the critical principles of security known as the confidentiality, integrity, and availability (CIA) triad. In addition to incorporating security controls that relate to the CIA triad, three other security features directly affect CIA and aid the overall site security program: access control, auditing, and backups. Although this chapter covers general Unix considerations, it also addresses several Linux specific items. This chapter is for all Linux variants: file names, directory paths, variable names, and so on, may also have to be taken into consideration. There are numerous versions of Linux, and it would be beyond the scope of this chapter to try to detail them all. All requirements listed within this chapter will pertain to all versions of Linux unless explicitly noted otherwise.

Book Description
Computer System and Network Security provides the reader with a basic understanding of the issues involved in the security of computer systems and networks. Introductory in nature, this important new book covers all aspects related to the growing field of computer security. Such complete coverage in a single text has previously been unavailable, and college professors and students, as well as professionals responsible for system security, will find this unique book a valuable source of information, either as a textbook or as a general reference. Computer System and Network Security discusses existing and potential threats to computer systems and networks and outlines the basic actions that are generally taken to protect them. The first two chapters of the text introduce the reader to the field of computer security, covering fundamental issues and objectives. The next several chapters describe security models, authentication issues, access control, intrusion detection, and damage control. Later chapters address network and database security and systems/networks connected to wide-area networks and internetworks. Other topics include firewalls, cryptography, malicious software, and security standards. The book includes case studies with information about incidents involving computer security, illustrating the problems and potential damage that can be caused when security fails. This unique reference/textbook covers all aspects of computer and network security, filling an obvious gap in the existing literature.

Book Description
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.

Book Description
"This project focuses on security issues related to adding and removing application software from a secure UNIX computing environment. Reports on related research include high-level descriptions of the officially supported utilities for adding and removing application software in several UNIX environments. Collectively, a fairly comprehensive approach is used to ensure correct and appropriate population of software. Individually, each of the systems researched possessed several major security flaws that could be exploited by an untrustworthy application software supplier. With an increase in destructive software entering secure computing environments, added safeguards must be exercized during software installation and removal to minimize the chance of compromising secure computing systems. This project describes security weaknesses, provides suggestions for correction and elimination of the weaknesses, and implements many suggestions while providing a comprehensive software framework for adding and removing software in a secure UNIX computing environment. The research provided builds on work done for CSC690 (Computer Security) and some of those results formed the basis for the software framework. The software framework consists of both Korn Shell scripts and C programs totaling over 3000 non-commentary source lines of code that execute in many UNIX environments, including the UNIX System V Release 3.2 and SUNOS 4.1.3 workstation environments. The framework provides integrity and security auditing, logging, and maintenance features, in a user friendly and extensible manner. This project consists of two products; the research embodied in this paper, and source code and documentation attached as an appendix to this paper."--Author's Abstract.
