1 Security of today’s internet-networked e-business enterprises is a major challenge. Vital network links and business flows need to be protected from external attack by cyber criminals or subversion by the criminal or irresponsible acts of insiders. Describe the various security tools and defensive measures that an organisation may use to protect their information system.

Discuss the security implications and challenges associated with network protocols, including common vulnerabilities and mitigation strategies.

Investigate the use of NAC (Network Access Control) systems in enforcing security policies and access control within corporate networks.

Analyze the security challenges specific to WANs, such as data encryption, authentication, and intrusion detection, and propose strategies to address these challenges effectively.

Explain the concept of zero-trust networking and its implications for network security and recovery. How does a zero-trust model improve network resilience against cyber threats and breaches?

Propose suitable information security mechanisms or techniques or methods based on the concept of confidentiality, integrity and availability for protecting Networks - WiFi, LAN and WAN. With Summary Table on the proposed security mechanisms, techniques or methods.

Module 1 New Discussion: Seven Domains Module 01 Discussion: Seven Domains A typical IT infrastructure has seven domains: User Domain, Workstation Domain, LAN Domain, LAN-to-WAN Domain, WAN Domain, Remote Access Domain, and System/Application Domain. Each domain requires proper security controls that must meet the requirements of confidentiality, integrity, and availability. Answer the following question(s): In your opinion, which domain is the most difficult to monitor for malicious activity? Why? In your opinion, which domain is the most difficult to protect? Why? Submission Instruction and Grading Evaluation Criteria: Students fully addressed the question(s) in the discussion instructions. Students included justification or rationale for their choices, where applicable. Reply to at least 2 post using a minimum of 50 words.  When responding, "I agree", "I like your post", etc. are NOT considered professional responses. Either agree, with explanation; disagree, with explanation; or…

Describe the various threats to network security and how they could be mitigated.

Analyze the security challenges associated with network protocols, including common vulnerabilities and mitigation strategies.

Discuss the security aspects of network protocols, focusing on encryption and authentication mechanisms. How do protocols like SSL/TLS and IPsec contribute to secure data transmission over networks?

Analyze the challenges and solutions related to WAN security in the era of remote work and increased cyber threats.

OSI Model- The OSI model had been around since 1984.  Why do you think that it exists,  what do you feel is its purpose and largest contributions?  Does the OSI model play any role in Computer and Network security? Hint: Do not use ChatGPT

Discuss the challenges and solutions for network security in virtualized environments.

What are the security techniques/mechanisms that might be utilized to safeguard vehicular communications or vehicle-to-vehicle communication? * The second question is how long each security technique/mechanism takes to encrypt and decrypt a communication.

Explore the security concerns associated with WANs, including data encryption, authentication, and intrusion detection/prevention.

Describe the principles of network segmentation and microsegmentation in IT security. How do these strategies enhance network security and access control?

Discuss the security implications of network protocols, focusing on common vulnerabilities and the measures taken to secure network communication.

What is the role of firewalls in network security? How do they protect a network from unauthorized access and threats?

Discuss the challenges and solutions related to WAN security, including topics like encryption, firewall implementation, and intrusion detection systems.

What are the potential security vulnerabilities and mitigation strategies associated with implementing Internet of Things (IoT) devices in a networked environment?

Discuss the security implications of network protocols, including common vulnerabilities and the role of protocols like HTTPS and VPNs in securing data transmission over networks.

What are the four network security vulnerabilities that Internet of Things (IoT) systems should be vigilant about?

Analyze the security protocols used in modern network security, including SSL/TLS, SSH, and WPA3. How do these protocols protect data during transmission and authentication?

Network security is a long-standing issue, requiring a careful balance between security and usability. With this in mind, look at the differences between IPv4 and IPv6 and comment on the new security features in IPv6, focusing specifically on ease of use and how effective you think they will be in maintaining the three tenets of Information Security: Confidentiality, Integrity, and Availability.

What are the trends in the area of network security and what are some big stories in the past few years?

Discuss the challenges associated with WAN security, including encryption, authentication, and intrusion detection.

Discuss the challenges and solutions related to network security in virtualized environments.

Analyze the security implications of common network protocols (e.g., HTTP, FTP) and discuss measures to mitigate potential vulnerabilities.
