The OWASP Top Ten and ESAPI – Final Summary

No Gravatar

Ok, well now we’ve been through all the issues listed in the 2007 version of the Top Ten. The new 2010 version is very similar with a couple discrepancies. I may follow up on those couple of issues at a later time. Hopefully you’ve seen through all the articles in this series that ESAPI (specifically the Java version was used) was built to deal with quite a few real security issues that developers face today. This series has shown that ESAPI can be used in almost every instance to either partially or completely remediate a specific issue, and to do it properly. The ESAPI community is thriving, and good things are coming out frequently. New implementations of some controls are showing up. New people are joining. New issues are being tackled. Get involved with this community and make it better. Use the outstanding controls this group has kindly given away, and offer some of your own.

Hopefully this series has been helpful to you in moving closer to secure J2EE development by exposing you to ESAPI and all it has to offer. I’ll be moving on to different topics in the future. Hope you enjoyed this one!

  1. I think that was an excellent series. My “special request” would be some recommendations on how to implement audit trail using ESAPI. In particular, something that would be in some way compliant with PCI recommendation 10. Thanks

    Thanks. I will look into PCI recommendation 10, and see if there are specific things that ESAPI can do to help deal with the requirements there. I will say that typically ESAPI is not built to meet specific business requirements, but rather provides certain controls to prevent certain classes of attacks, ie. part of the output encoding controls protect against XSS. There is, however, a logger in ESAPI. The default logger can be setup to do a certain type of output encoding to prevent problems like log forging. That might be a place to start.

  3. The series was excellent, The only think I disagree with you about was the numbering (OWASP Top 10 issue + 1) to get the right part.

    it’s much easier to rename part 1 -the intro- part 0 and be compliant with OWASP numbering for easy access to the issues.

  4. @Mostafa,
    Great idea – I renamed all the articles according to your suggestion. The urls stayed the same, but the titles and headers are updated. Should have done this in the first place.
