Which of the following scenarios would likely have the highest Threat Event Frequency?

The scenario of user passwords being reused across multiple platforms is likely to have the highest Threat Event Frequency due to the inherent vulnerabilities associated with password reuse. When users employ the same password across different platforms, it creates a weak point; if a cybercriminal gains access to one system through a data breach or phishing attack, they can leverage that password to access other systems where the same credentials are used. This amplifies the likelihood of unauthorized access events occurring.

In contrast, a well-secured server is designed with multiple layers of security, reducing the likelihood of successful attacks. Regular system audits in an organization are proactive measures that help identify and address vulnerabilities, further mitigating risks. An employee accessing data from a personal device may introduce risks, but depending on the organization's security policies and controls, the frequency of threat events may still be lower than the context of password reuse.
