Secure software starts before coding begins. Threat modeling, safer defaults, dependency hygiene, and developer workflow guardrails can help prevent vulnerabilities.
Software has a lifecycle. From the spark of an idea through coding, testing, deployment, customer use, and eventual revision or retirement, each line, module, and component becomes more entrenched, more solidified as part of the overall solution, and therefore much harder to fix if problems arise later. Yet, we often fix software solely based on late-stage usage. In this article, we'll discuss proactive strategies to prevent flaws from reaching production before deployment.
