Which of the following is the MOST effective mitigation strategy to protect confidential information from insider threats?
Click on the arrows to vote for the correct answer
A. B. C. D.D.
All of the options listed in the question are important mitigation strategies for protecting confidential information from insider threats. However, the MOST effective strategy would depend on the specific nature of the threat and the context in which it occurs.
Here's a brief explanation of each option:
A. Performing an entitlement review process: This involves regularly reviewing the access rights and permissions granted to employees and removing unnecessary privileges. By doing so, it limits the scope of information that insiders can access, and reduces the likelihood of data breaches or other malicious activities. This strategy can be effective in preventing accidental or unintentional breaches as well.
B. Implementing authentication mechanisms: Authentication mechanisms are used to verify the identity of users accessing a system or application. This could include passwords, two-factor authentication, biometrics, and other methods. By requiring users to authenticate themselves, it becomes harder for attackers to gain unauthorized access to confidential information. However, this strategy is not foolproof, as insider threats can often bypass authentication mechanisms.
C. Defining segregation of duties: Segregation of duties is the practice of dividing responsibilities among different employees to prevent any one person from having too much control over a process or system. This strategy can be effective in preventing insider threats from occurring, as it makes it harder for any one individual to carry out a malicious act. For example, if two employees need to collaborate to access a confidential system or application, it becomes harder for either of them to misuse the information.
D. Establishing authorization controls: Authorization controls are used to restrict access to specific data or systems based on a user's job responsibilities or other criteria. This strategy can be effective in preventing unauthorized access to confidential information, as it limits the scope of information that insiders can access. However, it may not be as effective in preventing accidental or unintentional breaches.
In summary, each of the options listed in the question can be effective in mitigating insider threats. However, the MOST effective strategy would depend on the specific context and nature of the threat. In general, a combination of multiple strategies would be most effective in protecting confidential information from insider threats.
