Which method can best protect against an insider threat?

Strong access controls and user permissions are essential for protecting against insider threats because they limit the ability of employees to access sensitive data that is not necessary for their roles. By implementing a principle of least privilege, organizations ensure that each employee has only the minimum level of access required to perform their job functions. This helps mitigate the risk that an insider, whether malicious or simply negligent, can exploit their access to sensitive information.

Furthermore, strong access controls can include measures such as authentication requirements, regular reviews of permissions, and segregation of duties. These practices deter potential insider threats by making unauthorized access more difficult and less tempting. Additionally, maintaining an audit trail of access requests and actions taken can help in detecting and responding to any suspicious behavior by insiders. This layered approach strengthens the overall security posture of the organization against risks that stem from within.
