What action could a company have taken to prevent unethical behavior regarding confidential information?

The chosen answer highlights a critical method in safeguarding confidential information by implementing access controls through computer passwords. By requiring passwords, organizations can restrict data access to authorized personnel only, thereby minimizing the risk of unauthorized users gaining entry to sensitive information. This helps create a secure environment where confidential data is protected from potential ethical breaches.

The use of computer passwords plays an essential role in maintaining data integrity and confidentiality. This method not only deters unethical behavior by limiting access but also establishes accountability, as actions taken within the system can be traced back to logged-in users.

While other options may promote security or accountability in various ways, they do not address the core issue of controlling access to confidential information as effectively as enforcing password protection does. For instance, tracking capabilities or anti-virus software, while beneficial in other respects, do not directly prevent unethical access to sensitive data. Requiring resignation does not solve the issue of data security and may not address the individual's behavior directly.
