Final answer:
Potential Risk Indicators (PRIs) are patterns of behavior noted from previous insider threat incidents that become significant indicators when combined with other suspicious behaviors, rather than being of high concern individually.
Step-by-step explanation:
Potential Risk Indicators (PRIs) are patterns of behavior that have been documented from previous insider threat incidents. While they can be indicators of possible insider threats, PRIs are often not significant on their own. Instead, they become more pertinent when observed in combination with other suspicious behaviors or indicators. For example, a PRI could be an employee displaying unusual interest in accessing data that is not relevant to their job role, which is more concerning if the employee is also observed trying to bypass security controls or displaying disgruntlement towards the organization. PRIs serve as warning signs and can help organizations identify and mitigate insider threats before they result in harm to the organization or its assets.
