What is insider threat and explain any two types?

An insider threat is a security risk that originates from within an organization, typically from employees, former employees, contractors, or business partners who have access to sensitive information or systems. Insider threats can be intentional, such as employees stealing data for personal gain or sabotage, or unintentional, such as employees falling victim to phishing attacks or accidentally leaking sensitive information. Insider threats are considered a significant security concern for organizations as they can cause significant financial and reputational damage.
