Influenza viruses contain an RNA genome surrounded by a protein capsid (coat) and a lipid envelope (membrane). They rely on two surface proteins (haemagglutinin, HA, and neuraminidase, NA) to bind to host cell receptors to gain entry. Once inside a cell, influenza viruses hijack the cellular functions and effectively turn the cell into a virus producing factory, with the synthesis of viral genome and proteins allowing virus particles to assemble and exit the cell. This overall process is representative of what viruses in general accomplish when infecting cells. Copyright 2024 by Edmonds College Department of Biology. All rights reserved.

Based on this information and your understanding of the definition of life, are viruses alive? Please explain. Include in your answer specific definitions of what it means to be alive (recall that the Freeman text describes 5 fundamental characteristics of life – what are these five characteristics?) and address whether or not these apply to viruses.

Scenario: You are a network administrator for a mid-sized company, and you’ve been receiving complaints from users about intermittent connectivity issues when accessing an external web service. To diagnose the problem, you decide to use the Windows tools as discussed in our lecture class. Question: How would you utilize Windows tools to troubleshoot the connectivity issues, and what insights do each of these tools provide? Provide explanations of how they differ in usage.

Scenario: You are a network security analyst in a company that relies heavily on TCP for its web applications and services. Recently, you have noticed unusual traffic patterns and potential security breaches. To address these concerns, you need to investigate the security issues associated with TCP and how they might affect the integrity and confidentiality of your network communications. Question: What are some common security issues associated with TCP, and how can they impact network communications? Provide explanation to anyone to illustrate these vulnerabilities.

Scenario: You are a network administrator responsible for managing a corporate network. Recently, you noticed unusual behavior on the network, including intermittent connectivity issues and unexpected traffic patterns. To investigate, you decide to analyze ARP (Address Resolution Protocol) broadcasts and explore the potential for ARP spoofing attacks. Question: What are ARP broadcasts, and how can they be exploited through ARP spoofing? Provide explanations to illustrate both the legitimate use of ARP broadcasts and the security risks associated with ARP spoofing.
