Research Paper On Computer Network Security Issues

Research Paper on Computer Network Security Issues

This final assignment will be a departure from the three previous analysis assignments. It will require you to research, develop, and write an APA formatted research paper on computer network security issues. Using the following steps will guide you through the process.

You have the basic knowledge of network hardware, software, and operational theory from your work during this course thus far, which will be utilized in this research effort. While some students may have considerable knowledge of cybersecurity issues, we are assuming you do not. The eBook Network Security: A Practical Approach, published in 2006, should be studied and utilized as your security issues resource, along with additional Internet research as you desire. The fundamental security issues described in it have not changed significantly.

The research paper should address the following questions:

  • Discuss the types and sources of security threats that can damage or destroy network operations and data, including both cyber threats and physical threats (such as building/server security, fire, personnel access).
  • Consider and discuss the types of cyber attacks that can be leveraged against network hardware, including keystroke loggers, attacks on routers and switches, network media, and other vulnerable hardware.
  • Examine cyber-attacks through different network topologies, such as types of networks and remote access, and identify which parts of the OSI model are most vulnerable to attack.
  • Research and detail specific cyber-attacks such as TCP spoofing, denial of service (DoS) attacks, wireless network attacks, and Internet of Things (IoT) security issues, explaining their inner workings and impacts.
  • Briefly discuss the human factor’s role in network security, including user compliance with security procedures like password management and susceptibility to phishing attacks.
  • Identify and elaborate on the five most critical factors or potential issues to monitor continuously to maintain a secure network.
  • Summarize the key points from your literature review and draw conclusions based on your research findings.

The research paper should be approximately 10 pages, double-spaced, and include a cover page and references, totaling at least 2800 words. Follow APA formatting guidelines and include at least 8 credible references. Visual aids such as diagrams and graphics are encouraged to enrich the content.

The document must be well-organized, professionally written, carefully proofread, and include clear introduction and conclusion paragraphs. Use headings throughout to improve readability and structure.

The completed paper is to be submitted by the course deadline: Sunday, May 10, 2020, at 11:59 pm EST.

Paper For Above instruction

In the rapidly evolving digital landscape, network security remains a vital concern for organizations and individuals alike. As networks become more complex and integrated with various technologies, understanding the multifaceted security threats and implementing robust defenses are imperative to protect sensitive data, maintain operational continuity, and ensure trust in digital systems. This research paper explores critical aspects of computer network security, focusing on threat categories, attack mechanisms, vulnerabilities across network topologies, specific cyber-attack techniques, human factors, monitoring essentials, and strategic conclusions grounded in current literature.

Introduction

The proliferation of interconnected systems and the advent of new technologies such as the Internet of Things (IoT) have significantly expanded the threat landscape for network security. As organizations increasingly rely on their networks for critical operations, they face an array of threats that can compromise confidentiality, integrity, and availability of data. This paper aims to elucidate these threats, examine attack vectors, and identify essential measures to foster resilient and secure networks.

Types and Sources of Security Threats

The first step in addressing network security is understanding potential threats. These threats broadly fall into two categories: cyber threats and physical threats. Cyber threats include malware, ransomware, phishing, man-in-the-middle attacks, and advanced persistent threats that exploit software vulnerabilities or social engineering tactics (Stallings, 2017). Physical threats involve direct access to hardware, such as unauthorized personnel gaining physical entry to server rooms, damage from environmental hazards like fire or flooding, and theft of equipment (Kizza, 2015). Both types of threats carry significant risks; cyber threats can disrupt operation remotely, while physical threats can cause irreversible damage to hardware and data repositories.

Vulnerabilities in Network Hardware

Network hardware—routers, switches, firewalls, and media—are critical points of vulnerability. Attackers may deploy keystroke loggers, hardware Trojans, or exploit firmware vulnerabilities to gain control (Chen et al., 2019). For instance, attacks on routers may include exploiting default passwords, firmware flaws, or configuration errors, enabling attackers to intercept or redirect traffic. Switches can be targeted through MAC flooding or VLAN hopping (Kumar et al., 2020). Physical access to hardware devices enables direct manipulation, underscoring the need for secure deployment and access controls.

Attacks Leveraged Through Network Topologies and OSI Model Vulnerabilities

Different network topologies such as star, mesh, and hybrid configurations influence attack vectors. Remote access mechanisms, VPNs, and cloud integrations expand attack surfaces. Certain OSI layers, notably the Application (Layer 7), Network (Layer 3), and Data Link (Layer 2) layers, are more vulnerable. Application-layer attacks like SQL injection target services running on top of the network, exploiting software vulnerabilities (Alshaikh & Obaid, 2020). Network-layer attacks include IP spoofing and ARP poisoning, which disrupt routing and traffic flow, while Data Link layer vulnerabilities can be exploited via MAC address spoofing or VLAN attacks.

Specific Cyber-Attacks on Network Infrastructure

Understanding specific attack techniques enhances preparedness. TCP spoofing involves forging TCP session packets to hijack sessions or redirect traffic (Zhou et al., 2021). Denial of Service (DoS) attacks aim to incapacitate resources, often via overwhelming traffic. Wireless network attacks, such as WPA/WPA2 cracking and rogue access points, compromise wireless communications (Conti et al., 2018). IoT security issues stem from inadequate device protections, default credentials, and unpatched firmware, enabling botnets like Mirai to launch large-scale attacks (Kolias et al., 2017).

Human Factors in Network Security

The human element remains a critical vulnerability. Users may fall prey to phishing schemes that lead to credential theft or inadvertently install malware (Von Solms & Van Niekerk, 2013). Password management, security awareness training, and enforcement of security policies are essential to mitigate these risks. Human errors, such as misconfigurations or neglecting updates, often serve as entry points for attackers.

Critical Factors for Maintaining a Secure Network

  1. Regular patch management to close vulnerabilities.
  2. Strong access controls and authentication mechanisms.
  3. Continuous network monitoring and anomaly detection.
  4. Implementation of intrusion detection and prevention systems (IDS/IPS).
  5. Employee training and security awareness programs.

Conclusion

Effective network security necessitates a comprehensive understanding of threats, vulnerabilities, and attack techniques. Regular updates, layered defenses, strict access controls, and trained personnel form the foundation of resilient networks. As technology advances, so does the sophistication of cyber threats, making ongoing vigilance, research, and adaptation essential to safeguard digital assets. Incorporating insights from contemporary literature affirms that proactive and strategic security measures are vital in maintaining operational integrity in an interconnected world.
