Network Security Plan For The Past Several Weeks

Network Security Planfor The Past Several Weeks You Have Addressed Sev

Network Security Plan for the past several weeks you have addressed several different areas of telecommunications and information technology in relation to different types of communication across the organizational footprint of Sunshine Health Corporation. Review the work you have done and formulate the Network Security Plan to be implemented across the network footprint. This is not to be an overly detailed report but to address different network concerns and recommendations for improving and securing organizational data, personnel records, intellectual property, and customer records. Please address the narrative plan as well as a network diagram (no IP addresses, or circuit data required) and what is being done to secure the network at different levels of the OSI model and the organizational structure. Please make sure that you bring in a minimum of two external sources to strengthen and support your presentation. The assignment should be 5 pages of content not counting title page, reference page or appendices (diagrams, budget sheet, equipment list, etc.). Please follow APA format. Note: it is suggested that as you are reviewing your previous assignments in order to complete this assignment, also be making modifications and refining your previous work in order to successfully complete the week seven assignment, which is a final project report.

Paper For Above instruction

The development of a comprehensive network security plan is essential for protecting the vital assets of Sunshine Health Corporation, including organizational data, personnel records, intellectual property, and customer information. Over the past several weeks, various aspects of telecommunications and information technology have been explored, laying a foundation for this final security strategy. This plan synthesizes previous insights into a cohesive framework, addressing vulnerabilities, proposing security controls, and outlining measures to ensure data confidentiality, integrity, and availability across the company's network footprint.

Introduction

Sunshine Health Corporation operates within a complex digital environment where information is exchanged across various communication channels and organizational layers. The increasing sophistication of cyber threats necessitates a multilayered security approach aligned with the OSI model and organizational hierarchy. This plan aims to establish a resilient network architecture emphasizing preventative, detective, and corrective controls to safeguard sensitive information against cyber-attacks, accidental breaches, and internal threats.

Network Infrastructure Overview

The network infrastructure encompasses multiple interconnected components, including routers, switches, firewalls, intrusion detection systems (IDS), virtual private networks (VPNs), and secure access points. The network diagram, although devoid of specific IPs or circuit data, illustrates a layered topology that segregates the corporate headquarters, remote campuses, and mobile workforce. Segmentation strategies are vital for minimizing lateral movement of threats and establishing clear security zones aligned with organizational functions.

Security Concerns and Vulnerabilities

Critical vulnerabilities identified include unencrypted data transmission, inadequate access controls, insufficient segmentation, and outdated security patches. phishing attacks and malware poses significant risks, especially targeting remote and mobile personnel. Insider threats and data exfiltration also remain concerns, exacerbated by inconsistent user training and lax adherence to security protocols.

Security Measures and Controls

Network Layer Security (OSI Layer 3)

At the network layer, deployment of robust firewalls and intrusion prevention systems (IPS) is prioritized to monitor and filter traffic based on predefined security policies. Virtual Private Networks (VPNs) are employed to encrypt communications for remote access, ensuring confidentiality of transmitted data. Additionally, Network Access Control (NAC) policies restrict device access based on compliance status.

Transport and Session Layer Security (OSI Layers 4-5)

Transport layer security is reinforced through the use of Transport Layer Security (TLS) protocols for web services, email, and other application-layer processes. Session management mechanisms incorporate timeout features and multi-factor authentication (MFA) to prevent session hijacking and unauthorized access.

Application and Data Security (OSI Layers 6-7)

Application-level controls include deployment of Web Application Firewalls (WAFs), encryption of data at rest and in transit, and strict access controls based on roles. Data Loss Prevention (DLP) technologies monitor data flows and prevent unauthorized transfer of sensitive information. Regular patching and software updates address known vulnerabilities at the application level.

Organizational Security Structure

The security framework aligns with organizational roles, delineating responsibilities across IT administrators, security officers, and end-users. Policies promote security awareness training, incident response procedures, and compliance with relevant regulations like HIPAA. A centralized Security Operations Center (SOC) is proposed to continuously monitor network activity and respond swiftly to threats.

Implementation of Security Technologies

To strengthen security, Sunshine Health will implement layered defenses, including endpoint security solutions, continuous network monitoring, and automated threat detection tools. Regular audits and vulnerability assessments will help identify and rectify emerging risks. Security policies will be reviewed periodically to adapt to evolving threats.

Conclusion

The proposed network security plan emphasizes a holistic approach integrating technical controls, organizational policies, and ongoing monitoring. By implementing these strategies, Sunshine Health Corporation can significantly reduce its exposure to cyber threats, protect its critical assets, and ensure compliance with industry standards and regulations. A continuous improvement cycle, supported by external sources such as cybersecurity frameworks and best practices, will sustain the security posture over time.
