Understanding Insider Threats
An insider threat occurs when a security risk originates from someone within your organization rather than an external attacker. This could include current or former employees, contractors, board members, or anyone who has had authorized access to company facilities, systems, or sensitive information. Because insiders already have some level of trust and access, these threats can be especially challenging to detect and prevent. Protecting the organization requires awareness and participation from everyone.
Steps You Can Take to Help Prevent Insider Threats
Speak up about unusual behavior
If you notice concerning actions from employees, vendors, or visitors, report them to your manager or supervisor right away. Early reporting can prevent minor issues from becoming major incidents.
Behaviors to watch for may include:
Employees expressing extreme frustration or hostility toward the organization
Individuals frequently working late or accessing systems outside normal business hours without a clear reason
Unauthorized devices being brought into the workplace
Contractors or inspectors moving into areas outside the scope of their assignment
Keep sensitive information secure
Avoid leaving confidential documents on your desk. Store them in a locked cabinet when not in use, and never write passwords on sticky notes or other visible surfaces.
Lock your computer when unattended
Always lock your workstation before stepping away, even briefly. This helps prevent unauthorized viewing or access to sensitive data.
Stay alert to shoulder surfing
Be mindful of people lingering near your workspace. Someone glancing at your screen or watching you type could be attempting to capture confidential information or passwords.
By remaining vigilant and following these best practices, you play a critical role in protecting your organization from insider threats and maintaining a secure work environment.
