Which of the following is NOT a type of insider threat relevant to SPED organizations?

In the context of insider threats within SPED (Special Education) organizations, it is important to distinguish between threats that originate from within the organization and those that come from external sources. "External hackers" refers to individuals or groups outside of the organization who attempt to gain unauthorized access to its systems or data, representing a typical external threat rather than an insider threat.

On the other hand, malicious insiders, negligent insiders, and compromised insiders are all classifications of insider threats. Malicious insiders intentionally misuse their access for harmful purposes, negligent insiders may inadvertently cause data breaches through careless behavior, and compromised insiders are individuals whose credentials have been stolen or misused, often without their knowledge. Each of these categories reflects threats that stem from individuals who are part of the organization, therefore impacting its security and integrity.

This distinction clarifies that external hackers do not fit within the insider threat framework, as they do not possess insider access or knowledge of the organization's operations, which is a key characteristic of insider threats.
