Goals
The OWASP Java Project's overall goal is to...
Produce materials that show J2EE architects, developers, and
deployers how to deal with most common application security
problems throughout the lifecycle.
In the near term, we are focused on the following tactical goals:
- Provide examples of how to prevent Cross Site Scripting attacks in popular web frameworks
- Provide examples of how to prevent SQL Injection in popular data access frameworks
- Provide examples of how to prevent LDAP injection in Java
- A practical guide to implementing a security policy for a Java web application
- Secure configuration guides for popular application servers
Current Tasks
Ideas
Please submit your ideas for the OWASP Java Project here (you can sign your ideas by adding four tilde characters like this ~~~~)
- It would be useful to have a library of J2EE security resources on the web. In addition to URLs, I think these should have short summaries that explain what the resource is about. I've clicked on far too many "J2EE Security" links only to find that the article is about implementing access control in Tomcat.
- A tool that automatically generates a security policy for a given application could be useful. The tool is first run in learning mode where it maps all the accesses that the application attempts and then generates a policy based on those access attempts. Status: tool sent to Stephen.
Design considerations
Objective: | Discuss the security implications of common J2EE architectures. This could be discussed in terms of: Authentication, Authorisation, Data Validation, Cross Site Scripting protection. Other architecture concerns such as scalability, performance and maintainability can also be mentioned, but the focus on security should not be lost.
Any other security concerns that should be addressed during the design phase should also be mentioned here. |

Noteworthy Frameworks
Objective: | Discuss important and relevant Java security frameworks that would be useful to architects. The information should be at a suitably high level, for example, by discussing the advantages and features as well as the associated costs (direct and indirect) of using the frameworks. |

Java Security Basics
Objective: | Provide an introduction into the basic security services provided by the Java language and environment. Remember to keep this relevant for web developers for the initial release - there may be a potential to expand this to thick clients in subsequent releases. |

SQL Injection
Objective: | Provide cursory background information on SQL injection and refer to the Guide for more indepth coverage (no need to duplicate info in the Guide). This section should provide practical advise and real-world code examples for developers. If you feel that a popular persistence framework is not covered, please add it! |

Code Analysis Tools
Objective: | The introduction should cover the advantages and short comings of code analysis tools. An overview of the current state of the art and the available tools would go well here. As a start, only open source tools are listed, but if vendors of commercial tools adhere to the Tutorial guidelines, these submissions will be gladly received. |

Securing Popular J2EE Servers
Objective: | Practical step-by-step guides to securing various J2EE servers. Examples of secure configurations can also be provided for download. If configurations are provided, they should be properly commented so that the rationale for configuration settings is clearly explained. Users of the configurations should be provided with enough information to make their own risk decisions. |

- Using Eclipse to verify Java applications
- Using Findbugs, PMD, Metrics, NCSS, jLint to find flaws and bugs
- Using WebScarab to find vulnerabilities in J2EE applications - is there anything that would be specific to J2EE apps here? Wouldn't using webscarab apply to all web apps? Stephendv 07:14, 17 July 2006 (EDT)
- Decompiling Java bytecode
Objective: | Define other Java security resources, links, papers and books that would be useful to the community. |
