Figures List of Tables List of Listings Preface Welcome to Java Security Solutions, a book that explains security in general and Java security in particular This book includes cryptography, algorithms, and architecture It provides practical solutions to security problems and not only describes the different security technologies, but explains why the different technologies exist and why you should use them The source code is done in Java and illustrates how security in Java works This book also shows how to extend Java to provide a more secure organization In this book, we wanted to show more than just how to use Java components We also wanted to show how to extend them, explain the reasons why algorithms like RSA are important, and inform readers about the basic protocols In short, we wanted to answer the what, when, how, and why of the Java components used in security solutions Why This Book? Some of the specifications that we address in this book include J2EE, WebServices, CORBA, JAAS, RMI, JSSE, SKIP, SASL, GSS-API, IPSec, X.509 certificates, cryptography, RSA, Elliptical Curve Cryptography, DSS, DSA, Kerberos, LDAP, TLS, WTLS, message digests, key agreements, key management, java access, ciphers, firewalls, network security, PKI, and much more This book helps you: Think as a hacker so that you can avoid the security pitfalls that hackers exploit Understand the building blocks of security so that you can take full advantage of security features Learn how to apply Java security features effectively and efficiently Get hands-on experience with security algorithms and their implementation Understand procedures for ensuring secure communications within the enterprise Learn how to add security to enterprise applications Understand ciphers Ensure message authentication and data integrity Understand network security architecture View your solution from beginning to end and look for vulnerable points along the way Why Java? These days, Java is the language of choice for the development of Web applications and enterprise solutions Typically, these are distributed systems requiring distributed communication among the components This distributed communication is supported by CORBA, RMI, or RMI over IIOP, and the combination of these technologies along with Java provide a tool set that allows the development of secure solutions Security has been a major design goal for Java ever since the creation of the language Java provides a language, runtime environment, APIs, and tools that are ideal for the development of secure systems The Java Development Kit (JDK) 1.4 comes standard with many cryptography components in its distribution and technologies that allow the support and development of secure solutions Some of these technologies include X.509 certificates, key agreement, a way to specify security policies, authentication, authorization, code signing, and cryptographic support The JDK 1.4 now integrates into its distribution the Java Cryptography Extension (JCE) as cryptography components and Java Authentication and Authorization Services (JAAS) Java also provides the Java Secure Socket Extension (JSSE) Although you can create solutions without these technologies, these solutions will probably be less portable and more expensive than if you use the JDK 1.4 It is definitely worth it to take your time and learn what Java has to offer In order for you to understand how these technologies can be used successfully, however, you need to understand the why, when, how, and what behind the different Java components That is where this book comes in What You Need to Know This book is for anyone who wants to understand security issues and how to prevent security violations If you want to understand how to address security concerns and how to implement many of the standards and protocols in Java, this book is for you The typical reader of this book is the intermediate to advanced Java developer, Java architect, and systems architect Basic Java programming knowledge is assumed, and therefore, concepts such as EJB deployment, Java language constructs, HTML, Web server and application server technologies are not covered in detail We address these concepts from the security perspective and not at an introductory level How This Book Is Organized This book provides a discussion on all aspects of security We begin by introducing security and its requirements Then we introduce the Java components that address these requirements, including the reasons why and how these components are to be used Then we move on to resource, enterprise, and network security This book is divided into nine parts Part I: Introduction to Security This part covers the basics of security, explains the need for security, and introduces you to the way hackers think, the tools that are available to hackers, and the most common attacks In addition, this part categorizes security elements and the different Java components available for security If you cannot wait to start with Java security, its components, and implementation, we suggest you skip to Chapter 3, "Java Security Components." Part II: Identity and Authentication This part provides an overview of key management algorithms, Elliptic Curve Cryptography (ECC), and Java implementation to keys and key management It includes key pair examples, a discussion of the mathematics, Diffie-Hellman, key generation, man-in-the-middle attack, RSA key exchange, ECC, secure random, and DES examples Part III: Data Integrity This part covers data integrity, hash functions, message digest algorithms, message authentication, and digital signatures This discussion includes RSA, ECC, MAC, SHA-1, and others It includes an MD5 implementation, a SHA-1 algorithm, a MAC algorithm, and DSA signature examples Part IV: Data Hiding This part presents ciphers, and how to implement ciphers including how to use CipherSpi Also, it presents a discussion on PBE, Blowfish, and Java Smart Cards This part includes examples on RSA and an example implementation, Stream Ciphers, PBE, and Blowfish Part V: Resource Access Using Java This part provides an overview of the common criteria for security It also helps you understand the need for security in your applications and how to satisfy those requirements using Java It presents JAAS, Kerberos, GSS-API, and the Security Manager It includes examples on security context, policies, configurations, guarded objects, signed objects, and JAAS Part VI: Enterprise Data Security This part covers the needs to secure your enterprise data This is mainly a discussion of why and how you can secure your database, and the communication between your application and the data repository It contains container-managed and application sign-on, and a discussion on the connector API Part VII: Network Access This part focuses on network security and architecture It discusses the OSI model, DMZs, firewalls, HTTP tunneling, Java Sockets, SSL, TLS, and JSSE It includes socket examples (including the server, client, and channel), routing tables, and X509 examples Part VIII: Public Key Management This part discusses Java digital certificates such as X500, and X.509 Also, this part describes PKI management with certificate chaining, X.500, LDAP, and the need for non-repudiation, including how to import certificates, CRL, CertPath, and LDAP examples Part IX: Enterprise Access This part covers the need for security of enterprise solutions It describes, including programming examples, the Java security model, Java permissions, Web-tier security, Web Services, JNDI, RMI, IIOP, and EJB security Finally, it presents a discussion of how BEA's WebLogic, IBM's WebSphere, and
