Get Started Fast with Objective-C 2.0 Programming for OS X, iPhone, iPod touch, and iPad

If you want to learn Objective-C 2.0 to write programs for Mac OS X, iPhone, iPad, or iPod touch, you’ve come to the right place! Concise, readable, and friendly, Learning Objective-C 2.0 is the perfect beginner’s guide to the latest version of Objective-C.

Longtime Mac OS X and iPhone developer Robert Clair covers everything from the absolute basics to Objective-C 2.0’s newest innovations. Clair begins with a practical refresher on C and object-oriented programming and walks you through creating your first Objective-C program with Xcode. Next, you’ll master each core language feature, from objects and classes to messaging, frameworks, and protocols. Every concept is illustrated with simple examples, and many chapters contain hands-on practice exercises.

Throughout, Learning Objective-C 2.0 focuses on the features, concepts, and techniques that matter most day to day. The result is an outstanding first book for everyone who wants to begin programming for iPhone, iPod touch, iPad, or Mac OS X.

COVERAGE INCLUDES

• Understanding methods, messages, and the Objective-C messaging system
• Defining classes, creating object instances, and using class objects
• Using categories to extend classes without subclassing
• Simplifying development with Objective-C 2.0 declared properties
• Using protocols to emphasize behavior rather than class
• Working with common Foundation classes for strings, arrays, dictionaries, sets, and number objects
• Using Objective-C control structures, including Objective-C 2.0’s new fast enumeration construct

End-to-End Network Security

Defense-in-Depth

Best practices for assessing and improving network defenses and responding to security incidents

Omar Santos

Information security practices have evolved from Internet perimeter protection to an in-depth defense model in which multiple countermeasures are layered throughout the infrastructure to address vulnerabilities and attacks. This is necessary due to increased attack frequency, diverse attack sophistication, and the rapid nature of attack velocity—all blurring the boundaries between the network and perimeter.

End-to-End Network Security is designed to counter the new generation of complex threats. Adopting this robust security strategy defends against highly sophisticated attacks that can occur at multiple locations in your network. The ultimate goal is to deploy a set of security capabilities that together create an intelligent, self-defending network that identifies attacks as they occur, generates alerts as appropriate, and then automatically responds.

End-to-End Network Security provides you with a comprehensive look at the mechanisms to counter threats to each part of your network. The book starts with a review of network security technologies then covers the six-step methodology for incident response and best practices from proactive security frameworks. Later chapters cover wireless network security, IP telephony security, data center security, and IPv6 security. Finally, several case studies representing small, medium, and large enterprises provide detailed example configurations and implementation strategies of best practices learned in earlier chapters.

Adopting the techniques and strategies outlined in this book enables you to prevent day-zero attacks, improve your overall security posture, build strong policies, and deploy intelligent, self-defending networks.

“Within these pages, you will find many practical tools, both process related and technology related, that you can draw on to improve your risk mitigation strategies.”

This is the official guide to passing the two MySQL certification tests for MySQL 5, the long-awaited major revision of MySQL. The number of MySQL certification exams taken has doubled in the last six months.

Certcities.com lists the MySQL certification as one of the top 10 certifications to grow in 2005. MySQL professionals need a way to distinguish themselves from the vast majority of database administrators and developers. With more than 4 million active installations, MySQL is the world's most popular open-source database. Known for its speed, reliability and case of use, MySQL has become a low-cost alternative to expensive database systems such as Oracle, IBM and Microsoft. MySQL AB has aggressively improved the feature set of MySQL with MySQL 5, making it more suitable for enterprise-level applications and uses. The MySQL certification tests, available at over 3,000 PearsonVUE testing centers, is a key component of this enterprise growth strategy, establishing a base level of skills for database users, administrators and programmers.

The MySQL Core Certification is aimed at the database user who wants proof of his or her abilities in such fundamental areas as SQL, data entry and maintenance, and data extraction. The MySQL Professional Certification test is designed for the advanced user who wants to prove his or her knowledge in such areas as database management, installation, security, disaster prevention and optimization. Both tests are thoroughly covered in the MySQL 5.0 Certification Study Guide . Written by Paul DuBois, the leading author of books on MySQL topics, and reviewed for technical accuracy by MySQL AB, this book is the fastest, most reliable way for MySQL users, developers, and administrators to prepare for either of the MySQL tests.
