Application software is always going to contain flaws. The trick is to catch the mistakes as early as possible, by building security into the entire software development life cycle (SDLC), writes Peter Wood of the ISACA Conference Committee and founder of First Base Technologies.
Vendors that have formal security standards for coding, for example based on the OWASP methodology for web developers, stand a much better chance of releasing secure software.
Regular testing throughout the development cycle is also critical, as well as independent testing prior to release. Potential customers should seek assurance from vendors that their developers have been trained in good security practice, that they have formal security checks in place throughout the SDLC, and that they engage independent security testers before releasing product to their customers.
