What is a challenge to detecting insider threats?

One major challenge in detecting insider threats is that insiders can operate over an extended period of time without raising suspicion. This prolonged engagement allows them to gather information or carry out malicious activities gradually, making them harder to detect compared to more overt threats. Additionally, insiders often have legitimate access to systems and data, which can mask their harmful intentions. Their familiarity with organizational processes and security measures enables them to navigate within the system without drawing attention, further complicating detection efforts. This ongoing threat necessitates continuous monitoring and comprehensive strategies to identify unusual behavior that might develop over time.
