Which of the following is a method to potentially eradicate insider threats?

The correct answer is that all of these choices are methods for potentially eradicating insider threats. Each of these options addresses different aspects of improving security and minimizing the risk posed by insiders.

Data encryption is critical because it protects sensitive information from unauthorized access, even if an insider has the technical means to access the data. By encrypting data both at rest and in transit, organizations can significantly reduce the chances of insider misuse.

Isolating storage can also be an effective strategy, as it ensures that data access is controlled and only available to those individuals who have a legitimate need to know. This minimizes the risk of insider threats by limiting the number of personnel who can access certain types of sensitive information.

Changing passwords regularly is another important practice for maintaining account security. By requiring employees to update their passwords frequently, organizations can reduce the risk that an insider's account might be misused, especially in cases where an employee leaves the company or has malicious intent.

Together, these strategies create a multi-layered security approach that can help protect against potential insider threats. Each component addresses a unique vulnerability, making it essential to incorporate all of them as part of an overarching security policy.
