Network Security is a comprehensive resource written for anyone who plans or implements network security measures, including managers and practitioners. It offers a valuable dual perspective on security: how your network looks to hackers who want to get inside, and how you need to approach it on the inside to keep them at bay.You get all the hands-on technical advice you need to succeed, but also higher-level administrative guidance for developing an effective security policy. There may be no such thing as absolute security, but, as the author clearly demonstrates, there is a huge difference between the protection offered by routine reliance on third-party products and what you can achieve by actively making informed decisions. You''ll learn to do just that with this book''s assessments of the risks, rewards, and trade-offs related implementing security measures.- Helps you see through a hacker''s eyes so you can make your network more secure.- Provides technical advice that can be applied in any environment, on any platform, including help with intrusion detection systems, firewalls, encryption, anti-virus software, and digital certificates.- Emphasizes a wide range of administrative considerations, including security policies, user management, and control of services and devices.- Covers techniques for enhancing the physical security of your systems and network.- Explains how hackers use information-gathering to find and exploit security flaws.- Examines the most effective ways to prevent hackers from gaining root access to a server.- Addresses Denial of Service attacks, "malware," and spoofing.- Includes appendices covering the TCP/IP protocol stack, well-known ports, and reliable sources for security warnings and updates.

Fully revised and updated, Relational Database Design, Second Edition is the most lucid and effective introduction to relational database design available. Here, you''ll find the conceptual and practical information you need to develop a design that ensures data accuracy and user satisfaction while optimizing performance, regardless of your experience level or choice of DBMS. Supporting the book''s step-by-step instruction are three case studies illustrating the planning, analysis, and design steps involved in arriving at a sound design. These real-world examples include object-relational design techniques, which are addressed in greater detail in a new chapter devoted entirely to this timely subject.* Concepts you need to master to put the book''s practical instruction to work.* Methods for tailoring your design to the environment in which the database will run and the uses to which it will be put.* Design approaches that ensure data accuracy and consistency.* Examples of how design can inhibit or boost database application performance.* Object-relational design techniques, benefits, and examples.* Instructions on how to choose and use a normalization technique.* Guidelines for understanding and applying Codd''s rules.* Tools to implement a relational design using SQL.* Techniques for using CASE tools for database design.

This is the second edition of the popular practitioner''s guide to SQL, the industry-standard database query language.

In a local area network (LAN) or intranet, there are many pieces of hardare trying to gain access to the network transmission media at the same time (i.e., phone lines, coax, wireless, etc.). However, a network cable or wireless transmission frequency can physically only allow one node to use it at a given time. Therefore, there must be some way to regulate which node has control of the medium (a media access control, or MAC, protocol). Ethernet is a MAC protocol; it is one way to regulate physical access to network tranmission media.Ethernet networking is used primarily by networks that are contained within a single physical location. If you need to design, install, and manage a network in such an envronment, i.e., home or small business office, then Ethernet Networking for the Small Office and Professional Home Office will give you an in-depth understanding of the technology involved in an Ethernet network.One of the major goals of this book is to demystify the jargon of networks so that the reader gains a working familiarity with common networking terminology and acronyms.In addition, this books explains not only how to choose and configure network hardware but also provides practical information about the types of network devices and software needed to make it all work. Tips and direction on how to manage an Ethernet network are also provided.This book therefore goes beyond the hardware aspects of Ethernet to look at the entire network from bottom to top, along with enough technical detail to enable the reader to make intelligent choices about what types of transmission media are used and the way in which the various parts of the network are interconnected.- Explains how the Ethernet works, with emphasis on current technologies and emerging trends in gigabit and fast Ethernet, WiFi, routers, and security issues- Teaches how to design and select complementary components of Ethernet networks with a focus on home and small business applications- Discuses the various types of cables, software, and hardware involved in constructing, connecting, operating and monitoring Ethernet networks

SQL Clearly Explained, Third Edition, provides an in-depth introduction to using SQL (Structured Query Language). Readers will learn not only SQL syntax, but also how SQL works.

Although the core of the SQL language remains relatively unchanged, the most recent release of the SQL standard (SQL:2008) includes two sets of extensions: 1) support for object-relational databases and 2) support for XML. As a result, the set of standard SQL commands has been greatly extended and this new edition takes that into account.

This new edition includes updated tips and tricks to reflect the current concepts of SQL and XML standards; several new chapters covering object-relational and XML extensions; and an ancillary package that includes case studies, a syllabus, exams and more.

This book is intended for working SQL programmers, database administrators, database designers, database analysts, and application system developers as well as those who are developing new features for database management systems who want to know about user needs. This would include anyone working with electronic content in the relational database context but also XML. Web services, etc.

Demonstrates how to formulate SQL queries and how queries are processed to maximize performance of the database management system Explains use of SQL to enter, modify or delete data to maintain database structural elements Covers in great detail new SQL application for XML to meet the growing XML usage in development of online content

Relational Database Design and Implementation: Clearly Explained, Fourth Edition, provides the conceptual and practical information necessary to develop a database design and management scheme that ensures data accuracy and user satisfaction while optimizing performance.

Database systems underlie the large majority of business information systems. Most of those in use today are based on the relational data model, a way of representing data and data relationships using only two-dimensional tables. This book covers relational database theory as well as providing a solid introduction to SQL, the international standard for the relational database data manipulation language.

The book begins by reviewing basic concepts of databases and database design, then turns to creating, populating, and retrieving data using SQL. Topics such as the relational data model, normalization, data entities, and Codd's Rules (and why they are important) are covered clearly and concisely. In addition, the book looks at the impact of big data on relational databases and the option of using NoSQL databases for that purpose.

Features updated and expanded coverage of SQL and new material on big data, cloud computing, and object-relational databases Presents design approaches that ensure data accuracy and consistency and help boost performance Includes three case studies, each illustrating a different database design challenge Reviews the basic concepts of databases and database design, then turns to creating, populating, and retrieving data using SQL
