Project: Securing a Microsoft Windows Environment Project Part 7: Network Security Controls Recommendations Scenario Due to the Always Fresh expansion, management wants additional network controls to protect their growing network. Tasks Consider the Windows servers and workstations in the domains of a typical IT infrastructure. Based on your understanding of network security controls, recommend at least four possible controls that will enhance the network’s security. Focus on ensuring that controls satisfy the defense in depth approach to security. Summarize your network security controls in a summary report to management.

You must provide rationale for your choices by explaining how each control makes the environment more secure.

Introduction

In today's rapidly evolving cyber threat landscape, securing organizational networks requires implementing multiple layers of defenses—a strategy known as defense in depth. This approach ensures that if one security measure fails, others continue to protect critical infrastructures. For a growing enterprise like AllWays Fresh, which relies heavily on Windows servers and workstations across its IT infrastructure, enhancing network security through well-planned controls is paramount. This paper recommends four robust network security controls designed to strengthen the environment, along with a detailed rationale for each, demonstrating how these measures contribute to a layered security architecture.

1. Network Segmentation and Segregation

The first recommended control is implementing network segmentation. This involves dividing the network into logical subnets or VLANs based on function, sensitivity, or department. For instance, separating the finance, HR, and manufacturing systems limits access to sensitive data and reduces the attack surface. Segmentation confines potential breaches to smaller areas, minimizing the impact and providing ease of monitoring traffic flows between segments (West & Bhattacharjee, 2021). This control aligns with defense in depth by preventing lateral movement of threats within the network. In practice, using VLANs and firewalls to segment critical resources makes unauthorized access more difficult and supports targeted security policies for each segment.

2. Deployment of Intrusion Detection and Prevention Systems (IDPS)

The second control involves deploying Intrusion Detection and Prevention Systems. These systems continuously monitor network traffic for suspicious activities, anomalies, or known attack signatures. An IDPS can alert administrators or automatically block malicious traffic in real-time, providing a dynamic response to threats (Scarfone & Mell, 2007). Integrating IDPS with existing firewall infrastructure enhances visibility into network traffic and provides an additional layer of defense beyond perimeter security. This centralizes threat detection, enabling rapid response and minimizing potential damage from malware, exploits, or unauthorized access attempts.

3. Implementation of Strong Access Controls and Multi-Factor Authentication (MFA)

Access management is critical for protecting Windows servers and workstations. Enforcing strict access controls based on the principle of least privilege ensures users only have permissions necessary for their roles. Coupled with multi-factor authentication (MFA), this significantly reduces risks associated with stolen credentials (O’Gorman, 2003). MFA requires users to verify their identity through additional factors such as a mobile device or biometric data, making unauthorized access more difficult for attackers. Properly configured access controls combined with MFA bolster security by preventing insider threats and thwarting external cyberattacks aimed at gaining administrative privileges.

4. Regular Patch Management and Security Updates

The final control emphasizes establishing a comprehensive patch management process. Keeping Windows servers and workstations up to date with the latest security patches is vital in preventing exploits of known vulnerabilities. Automated patch deployment, combined with routine vulnerability assessments, ensures that systems are resilient against emerging threats (Cohen & Cherry, 2019). This control acts as a preventive measure, closing security gaps before they can be exploited by attackers. In a large, distributed environment like AllWays Fresh, central management of updates enhances consistency and reduces the window of vulnerability.

Conclusion

In conclusion, implementing network segmentation, deploying IDPS, enforcing strong access controls with MFA, and maintaining rigorous patch management collectively create a multi-layered defense system—essential for safeguarding the expanding network infrastructure of AllWays Fresh. Each control contributes uniquely to the defense in depth philosophy by addressing different aspects of network security, from connectivity and monitoring to user authentication and vulnerability mitigation. Together, these measures significantly reduce the risk of cyber threats, protect sensitive data, and ensure operational continuity.
