Final answer:
The unauthorized disclosure of information that could harm national security and needs to be updated at least every 15 years refers to classified information. Regulations such as the National Security Act dictate its protection, while laws like the FOIA control its disclosure, with certain exemptions for security concerns. Balancing security with privacy continues to be a complex issue in the era of digital information.
Step-by-step explanation:
Information whose unauthorized disclosure could reasonably be expected to cause damage to national security and must be updated at least every 15 years best describes what is known as classified information. This type of information is protected under various laws and regulations, designed to maintain national security and protect sensitive government information from unauthorized disclosure. Among the statutes that govern the handling of such information is the National Security Act, which outlines how classified information should be shared and stored. The need to balance security with privacy is a significant concern in the digital age, as more information becomes digitally accessible, raising issues of potential misuse, theft, or threats to individual privacy.
The Freedom of Information Act (FOIA) allows the public to request access to government records but includes nine exemptions for issues ranging from national security to trade secrets. Figure 15.14 demonstrates how even released documents can be heavily redacted if agencies, such as the CIA, deem certain contents sensitive to national security. The debate over what constitutes an appropriate level of transparency versus the need to protect sensitive information is ongoing, with cases like the Pentagon Papers highlighting the fine line between the public's right to know and the need to safeguard national interests.
Legislation such as the Patriot Act and the Homeland Security Act has expanded governmental powers in the name of national security, especially following events like the 9/11 terrorist attacks. These acts amplify government abilities to collect and analyze information, which sometimes results in controversy over the infringement of privacy and limitation of free speech. Modern discussions on freedom of expression of ideas furthermore explore the tensions between maintaining freedom of speech on platforms like social media while protecting against information leaks that can pose security threats.
