Hi Andy, Good point about 4 (tool first). Sometimes security feature rollout can provide a good impetus. We saw that too, focused around crypto for PCI with one of our major customers.
The only real danger with following that path is that you tend to emphasize that security is a feature (and only a feature), which as we all know is a big misunderstanding among dev people. gem company www.cigital.com podcast www.cigital.com/silverbullet blog www.cigital.com/justiceleague book www.swsec.com -----Original Message----- From: Andy Steingruebl [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 09, 2008 10:59 PM To: Secure Coding Mailing List (SC-L@securecoding.org) Cc: Gary McGraw Subject: Re: [SC-L] Darkreading: Getting Started On Jan 9, 2008 4:48 PM, Gary McGraw <[EMAIL PROTECTED]> wrote: > hi sc-l, > > One of the biggest hurdles facing software security is the problem of how to > get started, especially when faced with an enterprise-level challenge.

Gary, I had success with #4, but not using the tools we usually think of for bootstrapping a program, namely static analysis or testing tools. When I took the position they had already settled on using Netegrity's Siteminder product for a common authentication and authorization scheme across all of the applications. I managed to get them to settle on doing a quasi-RBAC with Siteminder, using it almost as an identity service as well. Settling on one common high-quality authentication and authorization tool/framework had three effects: 1. It removed these services from the realm of development. They just had to integrate with it, but didn't have to figure out all of the corner cases to password changes, etc. that so often crop up, and people mess up in homegrown approaches. 2. It convinced developers to build clean interfaces in their code for things like authorization to call out externally and/or have the data provided to them in a standard fashion. By settling on RBAC it also helped a lot with role and permission modeling that did need to happen in the app. 3. In a shop that usually wanted to do everything itself, it broke that cycle and people got used to not having to write everything from scratch. It was a bit of a non-standard way to use a tool to bootstrap a security program. They essentially got sold Netegrity originally for the wrong reasons, but they picked it and in implementing it correctly did themselves a huge service. Just one data point on leading with a tool that focused more on architecture and design than it did on finding defects. -- Andy Steingruebl [EMAIL PROTECTED] _______________________________________________ Secure Coding mailing list (SC-L) SC-L@securecoding.org List information, subscriptions, etc - http://krvw.com/mailman/listinfo/sc-l List charter available at - http://www.securecoding.org/list/charter.php SC-L is hosted and moderated by KRvW Associates, LLC (http://www.KRvW.com) as a free, non-commercial service to the software security community. _______________________________________________
