An insider threat refers to a security risk that originates from within an organization. This can involve employees, contractors, or business partners who have inside information about the organization's security practices, data, or computer systems. Insider threats can be intentional, such as theft of sensitive information, or unintentional, like accidental data breaches due to negligence. Organizations often implement various strategies to mitigate insider threats, including employee training, access controls, and monitoring systems. By fostering a culture of security awareness and employing tools to detect unusual behavior, companies can better protect themselves from potential risks posed by insiders.
