Recent breaches in the supply chain have exposed vulnerabilities in the software development processes used by manufacturers. Attackers have taken advantage of compromised development tools, stolen credentials, and malicious packages from repositories like NPM to infiltrate production environments. These incidents emphasize the need for manufacturers to adopt secure software development life cycle (SSDLC) practices when assessing their partners. By integrating security measures throughout the software development process, companies can better protect their systems and reduce the risk of exploitation. This approach is increasingly vital as the manufacturing sector becomes a more frequent target for cyberattacks.
