Book Description

Expert Oracle and Java Security: Programming Secure Oracle Database Applications with Java provides resources that every Java and Oracle database application programmer needs to ensure that they have guarded the security of the data and identities entrusted to them. You’ll learn to consider potential vulnerabilities, and to apply best practices in secure Java and PL/SQL coding. Author David Coffin shows how to develop code to encrypt data in transit and at rest, to accomplish single sign-on with Oracle proxy connections, to generate and distribute two-factor authentication tokens from the Oracle server using pagers, cell phones (SMS), and e-mail, and to securely store and distribute Oracle application passwords.

Early chapters lay the foundation for effective security in an Oracle/Java environment. Each of the later chapters brings example code to a point where it may be applied as-is to address application security issues. Templates for applications are also provided to help you bring colleagues up to the same secure application standards. If you are less familiar with either Java or Oracle PL/SQL, you will not be left behind; all the concepts in this book are introduced as to a novice and addressed as to an expert.

• Helps you protect against data loss, identity theft, SQL injection, and address spoofing
• Provides techniques for encryption on network and disk, code obfuscation and wrap, database hardening, single sign-on and two-factor
• Provides what database administrators need to know about secure password distribution, Java secure programming, Java stored procedures, secure application roles in Oracle, logon triggers, database design, various connection pooling schemes, and much more Download Now »

Practical RichFaces also describes how to best take advantage of RichFaces—the integration of the Ajax4jsf and RichFaces libraries—to create flexible and powerful programs. Assuming some JSF background, it shows how you can radically reduce programming time and effort to create rich AJAX-based applications.

What you’ll learn

• How to build rich Internet applications with out-of-the-box RichFaces components
• Best strategies for implementing Ajax applications using RichFaces
• When best to use the two libraries
• How to create new skins for your app in no time
• How to create applications without needing to write any JavaScript code
