Insider threats are among the most difficult cybersecurity threats to detect and prevent. This is due to two main reasons:
Most security tools and solutions are focused on identifying and preventing external threats. They are not designed to detect suspicious behavior from approved users.
Many inside actors are familiar with the organization’s network settings, security policies and procedures, making it easier for them to avoid detection. They may also have knowledge of vulnerabilities, gaps or other shortcomings that can be exploited.
