Which of the following is an example of a treatment strategy for a continuous risk?

An email gateway continuously monitors and filters incoming and outgoing email traffic, actively blocking threats like phishing attempts as they occur. This ongoing, automated protection aligns with the definition of a treatment strategy for a continuous risk, as phishing is an ever-present threat. Background checks are a one-time preventative measure, not continuous. Dual control is a control mechanism for specific transactions, not a continuous risk treatment. Branch protection in CI/CD is a control for code integrity, not a continuous risk treatment for a general threat like phishing.
