Which threats are categorized as insider threats from an antiterrorism perspective?

Insider threats in the context of antiterrorism refer to risks that originate from individuals within an organization. These individuals may intentionally or unintentionally compromise security from the inside, which makes their actions particularly challenging to detect and mitigate.

Espionage, as an insider threat, occurs when someone with authorized access gathers sensitive information for malicious purposes, often for foreign entities. This can include activities such as stealing classified information or leaking secrets that could jeopardize national security.

Security negligence also falls under insider threats since it involves individuals failing to follow established protocols or guidelines that ensure security. This negligence may lead to vulnerabilities or unintentional exposure of sensitive information, which could be exploited by adversaries.

In contrast, the other options refer to threats that originate from outside the organization, such as foreign invasions, burglaries, and cyberattacks. These external threats are not classified as insider threats because they do not stem from individuals with authorized access or knowledge of the organization's internal operations. Understanding insider threats is crucial for developing robust countermeasures and ensuring the integrity of sensitive information within organizations.
