Understanding Insider Threats

Definition

Definition: An insider threat refers to any risk to an organization arising from an internal party’s access to its systems, assets, or data. This is important because insiders have privileged access that can be exploited either intentionally or unintentionally, leading to significant harm.

Types of Insider Threats

1. Malicious Threats: These involve deliberate actions by insiders to harm the organization, such as data theft or sabotage.
2. Unintentional Threats: These arise from negligence or mistakes, such as mishandling sensitive information.

Case Studies

• Malicious Example: In 2024, a former Google employee was charged with stealing AI trade secrets, highlighting the financial risks of malicious insider threats.
• Unintentional Example: A 2024 data breach at Home Depot, caused by a third-party vendor, underscores the potential damage from unintentional insider threats.

Step 5: Continuous Monitoring

Establish ongoing processes to detect and respond to emerging threats. This ensures that the organization remains vigilant against insider threats.
