According to the ISACA CRISC Review Manual, an enterprise risk management (ERM) process is a holistic approach to identifying, analyzing, responding to, and monitoring all types of risk that affect the achievement of the enterprise's objectives. The ERM process should consider all types of risk, including strategic, operational, financial, compliance, and reputational risks. Among these, strategic risks are the most important, as they have the potential to affect the enterprise's mission, vision, and goals. Therefore, risk with strategic impact should be included in the ERM process. References = ISACA CRISC Review Manual, 7th Edition, Chapter 1, Section 1.2.1, page 17.

A vulnerability is a weakness or flaw that can be exploited by a threat to cause harm or damage to an asset.
Employees holding the door open for others, so that trailing employees do not have to stop and swipe their own ID badges, is a behavior that best represents a vulnerability, as it bypasses the security control of the ID badge system, and allows unauthorized or unauthenticated access to the premises. This behavior can increase the risk of physical or logical security breaches, such as theft, vandalism, sabotage, or espionage. References
