Resilient Engineering Practices for Security Against Modern Threats
Software supply chains, composed of diverse tools, dependencies, and collaborative workflows, have become critical targets for malicious actors. Attackers exploit vulnerabilities in open-source components, CI/CD pipelines, and automated engineering processes, exposing organizations to significant risks. Resilience in this context demands a shift from reactive defenses to proactive strategies that integrate security directly into engineering workflows, ensuring vulnerabilities are addressed before they can be exploited.
