Introduction: Why Security Failures Rarely Begin in Production When major security incidents make headlines, people often focus on the final outcome—a breach, exposed credentials, ransomware, compromised cloud systems, or leaked customer data. What receives far less attention is where many of these problems actually begin. In most cases, security failures do not suddenly appear in production. They start much earlier. A misconfigured cloud resource, vulnerable dependency, exposed secret, weak CI/CD control, or poorly reviewed infrastructure change often exists long before anyone notices the damage. By the time vulnerabilities reach production environments, teams are usually no longer solving small mistakes. They are managing expensive consequences.
