Any person with or without authorized access to or knowledge of an organization’s resources, such as staff, facilities, information, equipment, networks, and systems, is considered an insider. Insider threat refers to the possibility that an insider will utilize their allowed access or knowledge of an organization to harm it. Malicious, complacent, or unplanned activities that compromise the integrity, confidentiality, or availability of the company, its data, staff, or facilities are examples of this harm.
