A manager Identifies active privileged accounts belonging to staff who have left the organization.

 A threat actor is an entity or individual that poses a potential harm or danger to an organization’s information systems or data. Terminated staff are the threat actors in this scenario, as they are former employees who may still have active privileged accounts that grant them access to sensitive or critical information or resources of the organization. Terminated staff may abuse their access privileges or credentials to compromise the confidentiality, integrity, or availability of the information systems or data, either intentionally or unintentionally. Unauthorized access is a threat event or action that occurs when an unauthorized entity or individual gains access to an organization’s information systems or data without permission or authorization. Unauthorized access is not a threat actor, but rather a result of a threat actor’s activity. Deleted log data is a threat consequence or impact that occurs when log data, which are records of events or activities that occur on an information system or network, are erased or corrupted by a threat actor. Deleted log data can affect the auditability, accountability, and visibility of the information system or network, and prevent detection or investigation of security incidents. Deleted log data is not a threat actor, but rather a result of a threat actor’s activity. Hacktivists are threat actors who use hacking techniques to promote a political or social cause or agenda. Hacktivists are not the threat actors in this scenario, as there is no indication that they are involved in this case.
