>From my experience with secappdev.org (http://secappdev.org), a not-for-profit organization set up to create security awareness and improve skills in the developer community, I find myself in agreement with many of the points that Sammy raises. Development is not only about coding. secappdev tends to pay relatively little attention to coding; adoption of new technologies offering novel opportunities to shoot yourself in the foot is so rapid, platforms so varied and applications so different that we have found teaching secure software engineering principles to be a better investment for both students and teachers alike. While it is certainly true that what ultimately matters is the code, conventional wisdom has it that coding only accounts for about 20% of the development effort. The rest of the time is spent in specification, design, test, deployment and project management. We feel it is counter-productive to draw sharp distinctions between these various activities, they all need to be done well to deliver a succesful project. So we spend considerable time looking at their security implications.
Apart from chiming in with Sammy, I would also like to point out that our target audience are application developers and their main focus is definitely not security, nor should it be: their job is to create value by adding functionality. Rather than teaching them to become security experts, we try to teach them strategies for getting away with as little security knowledge as possible so that they can focus on their core concerns. So one of the things we do is to make sure that participants have a good grasp of the security services offered by application platforms. An example of an architectural level discussion would be the choice of platform and its impact on security as well as how to mitigate the risks. Effective security teaching imparts a mindset, the body of knowledge is incidental. So we have a strong commitment to teach small groups with plenty of opportunity for interaction and immersion. At the next presentation, we are increasing the number of workshop sessions requiring participants to actively participate in problem-solving. So far, all secappdev.org presentations have been in Belgium and that may be a little out of the way for some/most of you. However, recordings of most of the last presentation are available from the web pages with the descriptions of individual sessions - mail me if you need fuller instructions. The next presentation is planned for the week starting March 3rd 2008. This will be a dual-track event. I hope to be able to publish the program very soon. kr, Yo On 8/17/07, Sammy Migues <[EMAIL PROTECTED]> wrote: > > Hi Chris, > > My experience is that, like most engineers, most software developers want to > improve their skills and that, as a group, they hate making easily-avoidable > mistakes of any sort.
