Which term represents the golden age of network security, emphasizing firewalls, VPNs, and DMZs to control network access?

• A. Perimeter Security
• B. FedRAMP
• C. Insider Threats
• D. Threat Intelligence

Answer: (A)

Perimeter security describes the traditional boundary-based approach to protecting a network, where the main defenses sit at the edge: firewalls monitor and control traffic between networks, VPNs provide secure channels for remote access, and DMZs host public-facing services with restricted access to the internal network. This model emphasizes controlling who and what can cross the network boundary, forming a protective shield around the trusted environment. It’s often called the golden age because these edge-based controls were the primary, most relied-upon defenses in many organizations. FedRAMP is about standardized security assessments for cloud services, not the boundary-focused edge protection described here. Insider threats refer to risks from people inside the organization rather than edge controls. Threat intelligence involves gathering information to anticipate attacks, not the network boundary defenses themselves.
