This OWASP cheat sheet for CISO is intended for an executive audience and for application security program assessors. It contains a list of application security program weaknesses that is intended to be built out over time, similar to MITRE's Common Weakness Enumeration (CWE) for software weaknesses. This list of program weaknesses is called the Common Program Weakness Enumeration (CPWE). The CPWE spans topics having to do with (1)institutionalization of an application security program and also (2)systems development touch points. An example of a CPWE use case is an organization having a SAMM or BSIMM assessment done, and the findings are mapped to CPWE-ID. Mappings are done in a similar fashion as one can for example generally configure software vulnerability assessment tools to map software weakness findings to CWE (or e.g. OWASP Top Ten), so that one can compare apples to apples regardless of program assessment methodology. I.e., regardless if for example SAMM or BSIMM was used. Long-term goals for leveraging the CPWE potentially include creating an OWASP CISO Top Ten project using the CPWE as inputs (i.e. that draws from the list), as a sort of brass ring for an OWASP CISO "guide".
Common Program Weakness Enumeration
The comprehensive CPWE dictionary view is below.
CPWE-xx: Insufficient Program Resources
- The software development organization or organizational unit has started an application security program, but the resources allocated to support the program (people, tools, or a combination thereof) are not sufficient, the initiative is either not funded or under-funded.
Modes of Introduction
- This weakness typically occurs in situations where there is no executive-level application security evangelist.
- Prior to a Cyber Incident - Delayed program adoption
- During and After a Cyber Incident - Unknown business risk; impaired incident response
"Insufficient Program Resources - (##)"..... if you only put someone on this half time you'll continue limping along trying to start a secure software development program........
"Lack of Verification Capability - (##)"........ if you have for instance only a couple people to get some elements of the program going but not enough to have an enforcement/verification capability..........
Etc, .. initial, then e.g. (make a pass through sp) .....some top-level generic using sp, 5 generic, e.g. missing or inadequate implementation phase activities ... risky or dangerous vendor service .. risky or dangerous application or service integration ((split all these 'ors' into separate ones)) .. missing policy .. missing standards .. missing systems development activity .. missing systems development gate .. failure to track compliance activities .. failure to track security bugs .. failure to protect source code from theft ... missing or inadequate developer training .. no reusable common security control libraries .. no secure coding standards .. no minimum lifecycle activities .. failure to address implicit contractual or regulatory requirements .. failure to address explicit contractual or regulatory requirements .. inappropriate or inadequate secure development lifecycle activity .. portfolio posture blindness .. application posture blindness .. potentially material event (add ref to draft guidance)
