What are the main benefits of adding a perimeter network and firewall rules according to a technology firm’s plans?

• A. Reducing costs and enhancing performance
• B. Isolating servers and filtering network traffic
• C. Simplifying user access management
• D. Enabling remote access for all employees

Answer: (B)

The main benefits of adding a perimeter network and firewall rules revolve around the concepts of isolation and traffic filtering, which enhance security measures for an organization's infrastructure. A perimeter network, often called a DMZ (demilitarized zone), acts as a buffer between an organization's internal network and the external internet. This architecture is crucial because it helps to isolate servers that handle external traffic, such as web servers or email servers, from the internal network where sensitive data resides. Implementing firewall rules further strengthens this strategy by controlling and filtering incoming and outgoing network traffic based on predetermined security rules. This allows an organization to restrict access to internal resources while still providing the necessary services to external users. Such measures help protect against threats, prevent unauthorized access, and mitigate potential attacks from the internet, ensuring that sensitive internal systems are secured and less exposed to vulnerabilities. While the other choices involve elements of IT infrastructure, they do not directly address the main benefits associated with the integration of a perimeter network and firewall rules in the context of security and traffic management. Cost reduction, performance enhancement, user access management, and remote access, while important, are more collateral benefits that may not be the primary reason for implementing these network security measures.
