Network System Security Plan Recommendation

CYB 230 Project –
Network System Security Plan Recommendation

Attached are the Assignment instruction document, Network diagram, Network Diagram description and the network system security plan

Overview

The goal of any security practitioner is a secure network, so it’s essential to have an in-depth understanding of how various components can introduce security vulnerabilities and mitigate security risks. Practitioners must be able to analyze networks, identify deficiencies, and make recommendations to protect the system. In this project, you will be making recommendations for specific components based on your systems-level analysis of a network.

The project will be submitted in Module Seven. You will demonstrate your mastery of the following course competency:

Identify and troubleshoot deficiencies related to IT-system component security
Scenario

During its annual review of IT systems, Helios Health Insurance has realized that it lacks the in-house expertise to update its network system security plan. The organization has therefore hired a consultant to assist in this process. You will assume the role of this security consultant, tasked with updating the organization’s network system security plan by identifying deficiencies and recommending mitigation solutions. In order to help you make your recommendations, you have been provided with the current Helios Network System Security Plan and the Helios Network Diagram. Both documents can be found in the Project Three Submission task in Module Seven of your course.

Prompt

After reviewing the network system security plan and the network diagram, select a security objective (confidentiality, integrity, or availability) as the focus for your analysis and recommendations. Then prepare a report to communicate the system’s deficiencies and your recommendations to the organization’s security team.

Specifically, you must address the critical elements listed below. The codes shown in brackets indicate the course competency to which each critical element is aligned.

Identify a hardware-based deficiency in the system and explain why this is an issue, based on your selected security objective.
Recommend a method to remediate the hardware-based issue and protect the system.
Identify a software-based deficiency in the system and explain why this is an issue, based on your selected security objective.
Recommend a method to remediate the software-based issue and protect the system.
What to Submit

Your submission should be 3 pages in length (plus a cover page and any references). Use double spacing, 12-point Times New Roman font, and one-inch margins. Sources should be cited according to APA style.

Network System Security Plan Recommendation

The significance of a secure network cannot be overstated, particularly in the face of the ever-evolving landscape of cyber threats. To achieve this crucial goal, a comprehensive understanding of the network’s components and their potential security vulnerabilities is essential. As a seasoned security practitioner, it is my responsibility to conduct a systems-level analysis of the network of Helios Health Insurance and make recommendations for mitigating potential risks and deficiencies.

II. Scenario: Helios Health Insurance

Helios Health Insurance has sought assistance from a security consultant to address deficiencies in its network system security plan. As the appointed consultant, my primary objective is to update the organization’s network system security plan by identifying vulnerabilities and suggesting effective mitigation strategies. I have been provided with the current Helios Network System Security Plan and the Helios Network Diagram, crucial references for crafting informed recommendations.

III. Focus: Security Objective Selection

In line with the project prompt, I will concentrate on the security objective of “integrity” for the analysis and recommendations. Maintaining the integrity of the network ensures that data remains accurate, unaltered, and trustworthy, making it a critical aspect of Helios Health Insurance’s security posture.

IV. Hardware-Based Deficiency

One hardware-based deficiency in Helios Health Insurance’s network system is the absence of robust intrusion prevention systems (IPS) at critical network entry points. Without an effective IPS, the network becomes vulnerable to unauthorized access and potential data breaches, directly compromising data integrity.

To address this issue, Helios should implement a cutting-edge IPS solution with intelligent anomaly detection capabilities. This IPS should be placed at network entry points to scrutinize incoming traffic for malicious activities and anomalous behavior. By doing so, the organization can proactively prevent potential security breaches and uphold the integrity of its sensitive data.

V. Software-Based Deficiency

Another area of concern lies in the software-based deficiency observed in the network system. Helios Health Insurance lacks an efficient and updated patch management system. The absence of proper patch management exposes the network to known software vulnerabilities, presenting a significant threat to data integrity.

To rectify this issue, Helios must institute a comprehensive patch management program. This program should prioritize critical updates and ensure timely deployment of security patches across all software systems. Automated patching mechanisms should be employed to expedite the process and minimize the window of exposure to potential exploits. Additionally, the organization should invest in vulnerability scanning tools to identify software weaknesses proactively.

In conclusion, the security of Helios Health Insurance’s network system can be significantly enhanced by addressing the identified deficiencies related to hardware and software aspects. By focusing on data integrity, the proposed measures will help protect against unauthorized access and data tampering, ensuring the confidentiality of sensitive information. The implementation of robust intrusion prevention systems and a comprehensive patch management program will bolster the organization’s overall security posture and fortify its defenses against emerging cyber threats.
