Blocking outside traffic that claims to be from within the organization is managed by which security control?

• A. AC-4 Information Flow Enforcement
• B. AC-3 Access Enforcement
• C. AC-8 System Use Notification
• D. AC-14 Permitted Actions without Identification or Authentication

Answer: (A)

Blocking outside traffic that claims to be from within the organization is fundamentally linked to the concept of information flow and how data is allowed to enter, move within, and exit an organization's systems. This involves ensuring that only legitimate traffic is processed, while unauthorized or forged traffic is effectively blocked to maintain security integrity. The chosen control, which focuses on information flow enforcement, is designed to enforce policies regarding the flow of information across different levels of the organization’s network. This means that it ensures data is only exchanged according to established security policies, allowing for necessary checks to be made to validate the authenticity of the traffic. In this context, it serves to guard against spoofed traffic that falsely claims to originate from within the organization, thus providing a safeguard against potential security breaches or attacks. In contrast, access enforcement is primarily concerned with granting or denying permissions based on user credentials and roles, while system use notification deals with messages to inform users of system policies or usage guidelines. Permitted actions without identification or authentication relate to actions that can be taken without any user verification, which inherently increases risk and is less applicable to the issue of blocking fraudulent traffic. Thus, information flow enforcement is the most precise control for managing the challenge of handling outside traffic that misrepresents itself as internal
