Define accidental threats?

They are threats that are accidently done by organization employees. In these threats, an employee unintentionally deletes any file or share confidential data with outsiders or a business partner going beyond the policy of the company.
Other common examples of accidental insider threats include: Accidental disclosure of information, like sending sensitive data to the wrong email address. Physical data release, such as losing paper records. Portable equipment loss, which includes not only losing laptops, but portable storage devices too as well.
Threats can be classified into four different categories; direct, indirect, veiled, conditional. A direct threat identifies a specific target and is delivered in a straightforward, clear, and explicit manner.
