Explanation:
The question asks about permissible activities within a Sensitive Compartmented Information Facility (SCIF) which relates to cybersecurity awareness. The correct answer among the provided options is a) Modifying file permissions, assuming it is done in compliance with SCIF guidelines and policies. Activities such as accessing external websites, installing unauthorized software, and sharing passwords with colleagues generally violate SCIF protocols and cybersecurity best practices because they can introduce security risks. For instance, entering identifying information into a website could potentially lead to a breach of confidential information. Similarly, downloading documents that might access the web, like photos, and opening them outside secure environments can also pose risks. If there's a need to access such a document, one should disconnect from the internet before opening to avoid potential data leakage.
