As a security analyst for a global technology conglomerate, you are responsible for monitoring the company's network for cybersecurity threats. One day, you detect suspicious activity indicating a potential insider threat involving a senior executive who has access to sensitive company data. Upon further investigation, you uncover evidence suggesting that the executive is involved in corporate espionage and planning to sell confidential information to a competitor. How should you handle this situation ethically, considering the implications for the company's reputation and the potential legal consequences?

Confront the executive directly and demand an explanation for their actions, risking retaliation and potential damage to your career.$$

Ignore the activity to avoid implicating a senior executive and maintain harmony within the organization, assuming that the potential damage caused by the breach is minimal.$$

Report the incident to the executive's supervisor without conducting any further investigation, assuming that management will handle the situation appropriately.$$

Document the evidence of corporate espionage, report it to the company's legal department and senior management, and cooperate with law enforcement authorities to ensure a thorough investigation and appropriate legal action.
