Faced with constant and rapidly evolving threats to information security, IT managers need to guard their organizations from cyber risks with an effective security system.Â
Now in its sixth edition, IT Governance provides best-practice guidance for companies looking to protect and enhance their information security management systems.Â The book has been fully updated to take account of current cyberÂ security and advanced persistent threats.Â Â It alsoÂ reflects the latest regulatory and technological developments, including the 2013 updates to ISO27001/ISO27002, and key international markets, including the UK, North America, the EU, and Asia Pacific.
Changes in the new edition include:Â - Full coverage of changes to data-related regulations in different jurisdictions and advice on compliance- Guidance on the new continual improvement model that replaces Plan-Do-Check-Act in the previous ISO standard- New developments in cyber risk and mitigation practices- The latest technological developments that affect IT governance and security- An explanation on theÂ new information security risk assessment process
How well does your organization respond to changing market conditions, customer needs, and emerging technologies when building software-based products? This practical guide presents Lean and Agile principles and patterns to help you move fast at scaleâand demonstrates why and how to apply these methodologies throughout your organization, rather than with just one department or team.
Through case studies, youâll learn how successful enterprises have rethought everything from governance and financial management to systems architecture and organizational culture in the pursuit of radically improved performance. Adopting Lean will take time and commitment, but itâs vital for harnessing the cultural and technical forces that are accelerating the rate of innovation.
The Complete Guide to Optimizing Systems Performance
Written by the winner of theÂ 2013 LISA Award for Outstanding Achievement in System Administration
Large-scale enterprise, cloud, and virtualized computing systems have introduced serious performance challenges. Now, internationally renowned performance expert Brendan Gregg has brought together proven methodologies, tools, and metrics for analyzing and tuning even the most complex environments. Systems Performance: Enterprise and the Cloud focuses on LinuxÂ® and UnixÂ® performance, while illuminating performance issues that are relevant to all operating systems. Youâll gain deep insight into how systems work and perform, and learn methodologies for analyzing and improving system and application performance. Gregg presents examples from bare-metal systems and virtualized cloud tenants running Linux-based UbuntuÂ®, FedoraÂ®, CentOS, and the illumos-based JoyentÂ® SmartOSâ¢ and OmniTI OmniOSÂ®. He systematically covers modern systems performance, including the âtraditionalâ analysis of CPUs, memory, disks, and networks, and new areas including cloud computing and dynamic tracing. This book also helps you identify and fix the âunknown unknownsâ of complex performance: bottlenecks that emerge from elements and interactions you were not aware of. The text concludes with a detailed case study, showing how a real cloud customer issue was analyzed from start to finish.
â¢ Modern performance analysis and tuning: terminology, concepts, models, methods, and techniques
â¢ Dynamic tracing techniques and tools, including examples of DTrace, SystemTap, and perf
â¢ Kernel internals: uncovering what the OS is doing
â¢ Using system observability tools, interfaces, and frameworks
â¢ Understanding and monitoring application performance
â¢ Optimizing CPUs: processors, cores, hardware threads, caches, interconnects, and kernel scheduling
â¢ Memory optimization: virtual memory, paging, swapping, memory architectures, busses, address spaces, and allocators
â¢ File system I/O, including caching
â¢ Storage devices/controllers, disk I/O workloads, RAID, and kernel I/O
â¢ Network-related performance issues: protocols, sockets, interfaces, and physical connections
â¢ Performance implications of OS and hardware-based virtualization, and new issues encountered with cloud computing
â¢ Benchmarking: getting accurate results and avoiding common mistakes
This guide is indispensable for anyone who operates enterprise or cloud environments: system, network, database, and web admins; developers; and other professionals. For students and others new to optimization, it also provides exercises reflecting Greggâs extensive instructional experience.

Computer networking and cybersecurity are challenging subjects, partly because of the constant rise and fall of related technologies and IT paradigms. As the title implies, much focus of this book is on providing the audience with practical, as well as, theoretical knowledge necessary to build a solid ground for a successful professional career.
A Practical Introduction to Enterprise Network and Security Management contains 12 chapters of the correct amount of coverage for a semester or quarter. It balances introductory and fairly advanced subjects on computer networking and cybersecurity to deliver effectively technical and managerial knowledge. It explains sometimes challenging concepts in a manner that students can follow with careful reading.
A Practical Introduction to Enterprise Network and Security Management is designed to offer impactful, hands-on learning experiences without relying on a computer lab. First, each chapter comes with practical exercise questions. In the class setting, they are good as individual or group assignments. Many of them are based on simulated or real cases, and take advantage of actual industry products and systems for a reader to better relate theories to practice. Second, there are a number of information-rich screen shots, figures, and tables in each chapter carefully constructed to solidify concepts and thus enhance visual learning.
A Practical Introduction to Enterprise Network and Security Management
In addition to the thorough technical details, managerial issues including, enterprise network planning, design, and management from the practitionerâs perspective are embedded throughout the text to assist balanced learning. Bearing in mind of the critical importance of security in todayâs enterprise networks, the text discusses the implications of network design and management on enterprise security whenever appropriate. Lastly, to reinforce knowledge in security management further, two chapters introduce the fundamentals of cybersecurity in terms of threat types and defense techniques.
