Which of the following actions does not enhance cyber supply chain security?

Conducting an inventory of all deliveries is important for overall supply chain management, as it helps in tracking the physical assets and ensuring that the right products are received and stored properly. However, this action does not specifically address cybersecurity concerns related to the supply chain.

Cyber supply chain security emphasizes protecting the information and systems involved in the supply chain from cyber threats. This includes securing the digital interfaces and connections that vendors and partners use to integrate with each other. Options such as implementing multifactor authentication, regularly updating software and systems, and training employees on cybersecurity measures directly contribute to strengthening the cybersecurity posture. They focus on preventing unauthorized access, ensuring that systems are protected against vulnerabilities, and promoting awareness among personnel, all of which are critical components in defending against cyber threats in the supply chain.

In contrast, simply inventorying deliveries does not offer any cybersecurity enhancements. While it's essential for operational efficiency, its role in safeguarding data integrity and protecting against cyber risks is limited.
