Auditing Overhead, Auditing Adaptation, and Benchmark Evaluation in Linux Lei Zeng1, Yang Xiao1* and Hui Chen2
SECURITY AND COMMUNICATION NETWORKS Security Comm. Networks 2015; 8:3523–3534 Published online 4 June 2015 in Wiley Online Library (wileyonlinelibrary.com). DOI: 10.1002/sec.1277 RESEARCH ARTICLE Auditing overhead, auditing adaptation, and benchmark evaluation in Linux Lei Zeng1, Yang Xiao1* and Hui Chen2 1 Department of Computer Science, The University of Alabama, Tuscaloosa 35487-0290, AL, U.S.A. 2 Department of Mathematics and Computer Science, Virginia State University, Petersburg 23806, VA, U.S.A. ABSTRACT Logging is a critical component of Linux auditing. However, our experiments indicate that the logging overhead can be significant. The paper aims to leverage the performance overhead introduced by Linux audit framework under various us- age patterns. The study on the problem leads to an adaptive audit-logging mechanism. Many security incidents or other im- portant events are often accompanied with precursory events. We identify important precursory events – the vital signs of system activity and the audit events that must be recorded. We then design an adaptive auditing mechanism that increases or reduces the type of events collected and the frequency of events collected based upon the online analysis of the vital-sign events. The adaptive auditing mechanism reduces the overall system overhead and achieves a similar level of protection on the system and network security. We further adopt LMbench to evaluate the performance of key operations in Linux with compliance to four security standards. Copyright © 2015 John Wiley & Sons, Ltd.

Linux at 25 PETERHISTORY H
Linux at 25 PETERHISTORY H. SALUS Peter H. Salus is the author of A n June 1991, at the USENIX conference in Nashville, BSD NET-2 was Quarter Century of UNIX (1994), announced. Two months later, on August 25, Linus Torvalds announced Casting the Net (1995), and The his new operating system on comp.os.minix. Today, Android, Google’s Daemon, the Gnu and the Penguin I (2008). [email protected] version of Linux, is used on over two billion smartphones and other appli- ances. In this article, I provide some history about the early years of Linux. Linus was born into the Swedish minority of Finland (about 5% of the five million Finns). He was a “math guy” throughout his schooling. Early on, he “inherited” a Commodore VIC- 20 (released in June 1980) from his grandfather; in 1987 he spent his savings on a Sinclair QL (released in January 1984, the “Quantum Leap,” with a Motorola 68008 running at 7.5 MHz and 128 kB of RAM, was intended for small businesses and the serious hobbyist). It ran Q-DOS, and it was what got Linus involved: One of the things I hated about the QL was that it had a read-only operating system. You couldn’t change things ... I bought a new assembler ... and an editor.... Both ... worked fine, but they were on the microdrives and couldn’t be put on the EEPROM. So I wrote my own editor and assembler and used them for all my programming. Both were written in assembly language, which is incredibly stupid by today’s standards. -

What you now hold in your hands is the first annual report of the GNOME Foundation, at the end of what has been an eventful year for us. Each year brings its challenges and rewards for the members of this global project. This year, many of our biggest challenges are in the legal arena. European countries have been passing laws to conform with the European Union Copyright Directive, and some, including France, have brought into law provisions which we as software developers find it hard to understand, but which appear to make much of what we do illegal. We have found our- selves in the center of patent wars as bigger companies jockey for position with offerings based on our hard work. And we are scratching our heads trying to figure out how to deal with the constraints of DRM and patents in multimedia, while still offering our users access to their media files. -

Praise for the Official Ubuntu Book
Praise for The Official Ubuntu Book “The Official Ubuntu Book is a great way to get you started with Ubuntu, giving you enough information to be productive without overloading you.” —John Stevenson, DZone Book Reviewer “OUB is one of the best books I’ve seen for beginners.” —Bill Blinn, TechByter Worldwide “This book is the perfect companion for users new to Linux and Ubuntu. It covers the basics in a concise and well-organized manner. General use is covered separately from troubleshooting and error-handling, making the book well-suited both for the beginner as well as the user that needs extended help.” —Thomas Petrucha, Austria Ubuntu User Group “I have recommended this book to several users who I instruct regularly on the use of Ubuntu. All of them have been satisfied with their purchase and have even been able to use it to help them in their journey along the way.” —Chris Crisafulli, Ubuntu LoCo Council, Florida Local Community Team “This text demystifies a very powerful Linux operating system . in just a few weeks of having it, I’ve used it as a quick reference a half dozen times, which saved me the time I would have spent scouring the Ubuntu forums online.” —Darren Frey, Member, Houston Local User Group This page intentionally left blank The Official Ubuntu Book Sixth Edition This page intentionally left blank The Official Ubuntu Book Sixth Edition Benjamin Mako Hill Matthew Helmke Amber Graner Corey Burger With Jonathan Jesse, Kyle Rankin, and Jono Bacon Upper Saddle River, NJ • Boston • Indianapolis • San Francisco New York • Toronto • Montreal • London • Munich • Paris • Madrid Capetown • Sydney • Tokyo • Singapore • Mexico City Many of the designations used by manufacturers and sellers to distinguish their products are claimed as trademarks. -

Monografia (Trabalho de Conclusão de Curso) - Curso Superior de Tecnologia em Análise e Desenvolvimento de Sistemas, Universidade Tecnológica Federal do Paraná, Câmpus Pato Branco. Pato Branco, 2016. Com o objetivo de fornecer um firewall de baixo custo para empresas de pequeno porte com tecnologia ARM, este projeto usa hardware e softwares de código aberto. Com a instalação do sistema operacional Linux no equipamento ARM foi implementado um firewall, com o intuito de proteger as aplicações contra ataques oriundos da Internet. Também foi implantado um Proxy com autenticação por usuário e senha para liberação do acesso à Internet e com filtros de conteúdo que efetuam a liberação ou bloqueios de acessos indevidos feitos pelos usuários. O projeto contém um sistema para geração de relatórios diários dos acessos de cada usuário com a intenção de aprimorar os filtros de conteúdo.
