Explanation:

An Insider threat is anyone with permitted access to an organization and who uses that access to harm the organization, intentionally or unintentionally. It is not necessarily a current employee of the firm but possibly a consultant, former employee or board of member. Potential insider threat can be detected by observing prior negative behavior. Most of the insider threat showed at least some possible signs of risk.
