Time To Impress Using What Youvelearned In The Class How Would You
Time to impress. Using what you’ve learned in the class how would you secure the following network? (Remember to explain and justify your answers) XYZ Enterprises has had many security issues over the past few months. You are a new hire and are now responsible for security at XYZ Enterprises. XYZ has an older router-based firewall in place between the network and the outside world. There are 25 workstations and 4 servers on site all running a free version of a software anti-virus. Employees must be able to access the Internet throughout the day and must have access to their email without any down time. Employees on the road should also be able to access the network information. What improvements do you make? Prioritize and justify your responses in detail. Copy and Paste Question Clearly and Thoroughly Answer the Question with at least 1 reference.
Paper For Above instruction
The security posture of XYZ Enterprises requires a comprehensive overhaul to address existing vulnerabilities and optimize protection while maintaining operational efficiency. Given the current setup, several key improvements should be implemented, prioritized based on impact, feasibility, and the need to align with best cybersecurity practices.
1. Upgrade Firewall Infrastructure
The existing router-based firewall is likely insufficient for modern security threats. An upgrade to a next-generation firewall (NGFW) is imperative. NGFWs offer advanced features like intrusion prevention systems (IPS), application-aware filtering, and integrated VPN support. These features enable granular control over network traffic, detect and block malicious activities faster, and support secure remote access (Chapple & Seidl, 2016). This upgrade would serve as the first line of defense against cyber threats.
2. Implement Advanced VPN Solutions
Given that employees need to access network information from remote locations, deploying robust VPN solutions is critical. A secure, SSL/TLS-based VPN allows encrypted remote access, ensuring confidentiality and integrity of data exchanged between remote employees and the corporate network. This will improve security for teleworking staff without hampering productivity (Choi, Kim, & Kim, 2020).
3. Enhance Endpoint Security
While all workstations and servers currently run free anti-virus software, these solutions are often limited in scope, lacking features such as real-time malware detection, firewall, or centralized management. Upgrading to a unified endpoint security platform, possibly incorporating endpoint detection and response (EDR), would provide better threat detection capabilities, continuous monitoring, and faster incident response. Additionally, deploying endpoint encryption solutions will protect data on individual devices, especially critical for remote access scenarios.
4. Segmentation and Network Zoning
Segregating the network into zones protects sensitive servers and data. Creating a demilitarized zone (DMZ) for exposed services such as email servers and web servers reduces the risk of lateral movement by attackers. Internal network segmentation limits access to critical assets and minimizes the impact of potential breaches. Implementing VLANs can facilitate effective segmentation and traffic control (Fitzgerald & Dennis, 2019).
5. Strengthening Authentication and Access Control
Implementing multi-factor authentication (MFA) across all access points, especially for remote access, significantly reduces the risk of unauthorized entry. Enforcing strict access controls and least privilege principles ensures users can only access what is necessary for their roles. Role-based access control (RBAC) can be employed to manage permissions efficiently.
6. Regular Patch Management and Security Updates
Ensuring all systems, including operating systems, applications, and network devices, are regularly patched is crucial to fix known vulnerabilities. Automated patch management tools should be used to reduce oversight and ensure timely updates.
7. Continuous Monitoring and Security Awareness Training
Deploying Security Information and Event Management (SIEM) systems enables real-time monitoring of network activity and rapid detection of anomalies. Complementing technological solutions with employee security training enhances the organization’s overall security posture, educating staff on phishing, social engineering, and safe practices.
Conclusion
The security improvements for XYZ Enterprises should be implemented in a prioritized manner, starting with upgrading core network defense mechanisms such as the firewall and VPN, followed by endpoint protections and network segmentation. These steps will fortify the network against external and internal threats, ensure operational continuity, and empower remote workforce security. Continual monitoring and employee training further reinforce the security framework, making XYZ Enterprises resilient to evolving cyber threats.
