Overview
The goal of this assignment is to design a network defense system that strategically positions various network assets to ensure their security from potential threats. A well-conceived network topology can effectively protect sensitive information and assets while maintaining functionality for users. This report includes a comprehensive diagram illustrating the network's architecture, an outline of essential devices, a discussion of the selected network defense strategies, encryption policies, and a disaster recovery plan.

Network Asset Placement
Diagram of Network Defense
The proposed diagram illustrates the network defense layout, which consists of the following components:
1. Mobile Devices: 10 devices including smartphones, laptops, and tablets designed for user mobility.
2. Desktop Computers: 5 stationary devices placed within the internal network for stationary tasks.
3. Servers: 2 servers dedicated to file storage and email services.
4. Printer: 1 network printer to serve all devices within the office.
5. Router/Firewall: This device manages all incoming and outgoing traffic and acts as a barrier against potential threats.
6. WAN/Gateway Connection: 1 connection to access external networks, enabling Internet capabilities while implementing security measures.
7. Switch: This device facilitates communication between different networked devices.
8. Backup/Replication Asset: A dedicated local or remote server for data backup to ensure recovery from disasters.
Furthermore, Small Office/Home Office (SOHO) solutions – such as VPN services and endpoint protection software – will be incorporated to safeguard end-user devices and infrastructure (Smith, 2021).
Comprehensive Explanation of Topology Design
Rationale Behind Topology Design: The design leverages a segmented network structure to reduce vulnerability (Jones, 2022). By logically separating device functions, an organization can restrict access to sensitive areas while optimizing performance. The key motivators for this are to enhance security, preserve the integrity of data, and diminish risks associated with centralized designs (Johnson & Smith, 2023).
Threat Models: The primary threats considered in this design include unauthorized access, malware infections, and denial-of-service attacks (Williams, 2023). A layered defense approach is employed, where firewalls, intrusion detection systems (IDS), and encryption protocols serve to fortify the network against these threats.
Network Motivations and Ideologies: The network's design adheres to principles of defense in depth (Harris, 2021). By deploying multiple security measures that operate in tandem, the network aims to establish a robust defense mechanism. Furthermore, user education and endpoint security solutions are integrated to instruct users on security protocols, thereby decreasing human error susceptibility (Bishop, 2021).
Network Defense Solution List
1. Firewalls: Hardware firewalls at the network perimeter combined with software firewalls on individual devices.
2. Antivirus Solutions: Endpoint protection software that provides real-time malware detection and automatic updates.
3. Intrusion Detection/Prevention Systems (IDPS): To monitor network traffic for suspicious patterns and mitigate potential breaches.
4. Virtual Private Networks (VPNs): To ensure secure remote access to the organizational network.
5. Encryption Protocols: Utilization of SSL/TLS for data transmission and AES for data at rest.
Encryption Policies
Data Encryption: Sensitive information, both in transit and at rest, will be encrypted using industry-standard protocols (NIST, 2021). For instance, TLS (Transport Layer Security) will be used for secure email communication, while AES-256 encryption will encompass data stored on internal servers.
End-User Encryption: Specifically for mobile devices and user laptops, full-disk encryption will be applied to prevent unauthorized access in case of theft (Black & White, 2022).
Disaster Recovery Plan
Restoration Plans: The disaster recovery strategy comprises a hybrid backup solution and routinely scheduled backups (Edwards, 2023). Local backups will be conducted daily, while offsite backups will take place weekly. Cloud storage solutions will facilitate quick data recovery and operational continuity.
Testing of Plans: The organization will perform regular disaster recovery simulations to evaluate recovery speed and efficiency, ensuring that all employees are familiar with the procedures to follow during a crisis.
Summary
Implementing this network design meets essential expectations for securing network devices and protecting information assets. The strategic placement of devices and applications of layered defense mechanisms are critical in safeguarding data integrity against threats. The outlined recovery plan ensures operational resilience by enabling quick recovery from data loss incidents.
While the design is comprehensive, continuous assessment and improvement of security measures are vital as new threats evolve. Future recommendations include employing AI-driven tools for threat intelligence and real-time monitoring, which can greatly enhance the network security posture (Patel, 2023).
