Implementations should leverage existing security standards and implementations to ensure that (four items):

• A. all communications can be encrypted to prevent unauthorized access; no information leaks when errors occur; no active script content can be injected into narrative resources; full audit trails can be constructed and used to detect anomalous access patterns
• B. all communications can be encrypted to prevent unauthorized access
• C. no information leaks when errors occur
• D. full audit trails can be constructed and used to detect anomalous access patterns

Answer: (A)

The main concept is that security should be built on established standards and implementations to cover multiple protective controls at once. By following existing security standards, implementations can ensure communications are encrypted in transit (using TLS), so data remains confidential and intact as it moves between parties. It also promotes proper error handling that doesn’t reveal sensitive internal details, reducing information leaks when something goes wrong. Applying vetted practices for content safety—such as sanitizing narrative resources to prevent injected scripts—helps block malicious client-side content from executing. And implementing standard auditing capabilities, aligned with compliance needs, enables full audit trails to be generated and analyzed for anomalous access patterns. Together, these four areas form a cohesive security stance rather than relying on ad hoc measures. Other options tend to focus on a single aspect (e.g., only encryption or only auditing) and miss the broader, integral set of protections provided by leveraging established standards.
