“In the Java world, security is not viewed as an add-on a feature. It is a pervasive way of thinking. Those who forget to think in a secure mindset end up in trouble. But just because the facilities are there doesn’t mean that security is assured automatically. A set of standard practices has evolved over the years. The Secure® Coding® Standard for Java™ is a compendium of these practices. These are not theoretical research papers or product marketing blurbs. This is all serious, mission-critical, battle-tested, enterprise-scale stuff.”
—James A. Gosling, Father of the Java Programming Language
An essential element of secure coding in the Java programming language is a well-documented and enforceable coding standard. Coding standards encourage programmers to follow a uniform set of rules determined by the requirements of the project and organization, rather than by the programmer’s familiarity or preference. Once established, these standards can be used as a metric to evaluate source code (using manual or automated processes).
The CERT® Oracle® Secure Coding Standard for Java™ provides rules designed to eliminate insecure coding practices that can lead to exploitable vulnerabilities. Application of the standard’s guidelines will lead to higher-quality systems–robust systems that are more resistant to attack. Such guidelines are required for the wide range of products coded in Java–for devices such as PCs, game players, mobile phones, home appliances, and automotive electronics.
After a high-level introduction to Java application security, seventeen consistently organized chapters detail specific rules for key areas of Java development. For each area, the authors present noncompliant examples and corresponding compliant solutions, show how to assess risk, and offer references for further information. Each rule is prioritized based on the severity of consequences, likelihood of introducing exploitable vulnerabilities, and cost of remediation.
The standard provides secure coding rules for the Java SE 6 Platform including the Java programming language and libraries, and also addresses new features of the Java SE 7 Platform. It describes language behaviors left to the discretion of JVM and compiler implementers, guides developers in the proper use of Java’s APIs and security architecture, and considers security concerns pertaining to standard extension APIs (from the javax package hierarchy).The standard covers security issues applicable to these libraries: lang, util, Collections, Concurrency Utilities, Logging, Management, Reflection, Regular Expressions, Zip, I/O, JMX, JNI, Math, Serialization, and JAXP.

He brings forth his experience and learning from developing and securing service oriented applications, server monitoring software, mobile device applications, web-based data miners, and designing user-friendly security interfaces.
Robert C. Seacord is a computer security specialist and writer. He is the author of books on computer security, legacy system modernization, and component-based software engineering.
Robert manages the Secure Coding Initiative at CERT, located in Carnegie Mellon’s Software Engineering Institute in Pittsburgh, Pennsylvania. CERT, among other security-related activities, regularly analyzes software vulnerability reports and assesses the risk to the Internet and other critical infrastructure. Robert is an adjunct professor in the Carnegie Mellon University School of Computer Science and in the Information Networking Institute.
Robert started programming professionally for IBM in 1982, working in communications and operating system software, processor development, and software engineering. Robert also has worked at the X Consortium, where he developed and maintained code for the Common Desktop Environment and the X Window System. Robert has a bachelor’s degree in computer science from Rensselaer Polytechnic Institute.
Dean F. Sutherland is a senior software security engineer at CERT. Dean received his Ph.D. in software engineering from Carnegie Mellon in 2008. Before his return to academia, he spent 14 years working as a professional software engineer at Tartan, Inc. He spent the last six of those years as a senior member of the technical staff and a technical lead for compiler backend technology. He was the primary active member of the corporate R&D group, was a key instigator of the design and deployment of a new software development process for Tartan, led R&D projects, and provided both technical and project leadership for the 12-person compiler back-end group.
David Svoboda is a software security engineer at CERT. David has been the primary developer on a diverse set of software development projects at Carnegie Mellon since 1991, ranging from hierarchical chip modeling and social organization simulation to automated machine translation (AMT). His KANTOO AMT software, developed in 1996, is still in production use at Caterpillar. He has over 13 years of Java development experience, starting with Java 2, and his Java projects include Tomcat servlets and Eclipse plug-ins. David is also actively involved in several ISO standards groups: the JTC1/SC22/WG14 group for the C programming language and the JTC1/ SC22/WG21 group for C++.
