Insider Threat

Definition ∞ An insider threat is a security danger originating from within an organization, posed by individuals who have authorized access to systems or data. In the digital asset realm, this can involve employees or contractors misusing their privileges to steal funds, manipulate markets, or compromise sensitive information. Such threats require robust internal controls.
Context ∞ The discussion around insider threats in the cryptocurrency industry often highlights the need for stringent access controls, background checks, and continuous monitoring of personnel with privileged access. Particular attention is given to entities handling significant amounts of user funds or proprietary data. Future efforts will likely focus on developing advanced threat detection systems and fostering a culture of security awareness.
