Final answer:
Guidance for marking sensitive compartmented information deals with protecting classified data and is guided by strict protocols and regulatory documents, such as Executive Order No. 14,028, aimed at improving cybersecurity.
Step-by-step explanation:
Guidance for marking sensitive compartmented information (SCI) in the realm of cyber awareness is highly specialized and generally pertains to safeguarding classified information within government agencies. The process of marking SCI is governed by strict protocols to ensure that such information is only accessible to individuals with the appropriate security clearances. This is illustrated in CIA documents that show how information released under the Freedom of Information Act (FOIA) can still be heavily redacted to protect sensitive data, as indicated by the black marks covering the text.
Furthermore, Executive Order No. 14,028, as issued in 2021, outlines the importance of improving the nation's cybersecurity framework. This order emphasizes the necessity of updating cybersecurity policies, practices, and standards to protect sensitive information from cyber threats and unauthorized access, which could include SCI. As cyber threats evolve, this guidance, along with other regulations, helps to ensure that sensitive compartmented information is handled with the utmost security and discretion in the digital realm.
