ESAPI Assurance

Building an Assurance Case for ESAPI

 * Arguing Security - Creating Security Assurance Cases


 * summary: make Claims, provide supporting Evidence, and make Arguments for how the evidence supports the claims


 * Highest level claim is "The system is Acceptably Secure" but how to break this down into sub-claims that map to the provided evidence? e.g. absence of specific vulns (as investigated by manual testing or tool scans)


 * Hey! How about an explicit threat model??? Especially, what are our assumptions.


 * claims could be summarized using a  Software Facts Label


 * each language (Java, ASP, etc.) may need separate claims


 * list the third-party software


 * discuss coding practices that were followed, skill levels of developers, amount of independent review


 * publish scanning tool results. "Tool X, using rule set R on date D,  was run against ESAPI version Y using configuration Z, and found this set of results with this amount of code coverage."

Coding Practices

 * was OWASP Top Ten followed?


 * how was performance and security balanced?


 * what is the level of training of the developers? amount of experience in web development?


 * were tools part of the whole process or run at the end?


 * how was code repository prevented from unauthorized alterations?


 * practices for code check-in and independent review - how is introduction of Trojans avoided?


 * what threat level is being accounted for (e.g. will this only work against script kiddies)? was threat modeling used?
