From the Document: "'Whistleblowing' can be defined as 'the act of reporting waste, fraud, abuse and corruption in a lawful manner to those who can correct the wrongdoing.' Intelligence community (IC) whistleblowers are those employees or contractors working in any of the 17 elements of the IC who reasonably believe there has been a violation of law, rule, or regulation; gross mismanagement; waste of resources; abuse of authority; or a substantial danger to public health and safety. The IC has publicly recognized the importance of whistleblowing, and supports protections for whistleblowers who conform to guidelines to protect classified information. [...] In early 2018, Congress passed legislation to address perceived gaps in protections for IC contractors. Separate legislation under Title 10 of the U.S. Code, along with DOD implementing guidance, provides protections for members of the Armed Forces, including those assigned to elements of the IC."
