When deciding whether to apply specific updates, it is best to follow ________, in order to demonstrate due care.

Demonstrating due care in applying updates involves adhering to established best practices to maintain the security and integrity of systems. Following vendor guidance is essential because software vendors provide updates specifically designed to address vulnerabilities, enhance performance, and improve security for their products. This guidance is based on the vendor's expertise and understanding of the particular software, ensuring that the updates are relevant and necessary for that environment. By aligning with vendor guidance, organizations can ensure they are implementing changes that maintain compatibility and security.

Internal policy can provide a framework for how updates should be handled, but it may not always reflect the most current or specific recommendations from the vendors. Competitors' actions might not be applicable or relevant to a particular organization's unique setup or security requirements. Regulations can establish minimum compliance standards but do not provide the necessary specifics about each software product's updates. Therefore, following vendor guidance is the most effective and safe approach to showcase due care in cloud security management.
