How LAN Servers Contribute to Rapid Virus Dissemination

C.

Local Area Network (LAN) servers can contribute to a rapid dissemination of viruses due to several reasons. The BEST response for an IS auditor to explain this would be option C: the server's file-sharing function facilitates the distribution of files and applications.

The following are some of the reasons why LAN servers can contribute to the rapid dissemination of viruses:

1. File sharing: LAN servers provide a platform for users to share files and applications. While this feature can enhance collaboration and communication, it can also facilitate the spread of viruses. When a virus infects a file or application on a server, it can quickly spread to other files and applications shared on the server.

2. Common software: LAN servers often host software that is commonly used by multiple users. This software can be a prime target for viruses, and once infected, can spread the virus to other files and applications on the server.

3. Operating system vulnerabilities: LAN servers run on operating systems that may have vulnerabilities that can be exploited by viruses. Once a virus infects the server's operating system, it can spread rapidly to other files and applications on the server.

4. User behavior: LAN servers are used by multiple users, and their usage patterns may be similar. For instance, users on a given server may use similar applications and files. This similarity in usage patterns can make it easier for viruses to spread from one user to another.

In conclusion, the file-sharing function of LAN servers facilitates the distribution of files and applications, which makes them susceptible to the rapid dissemination of viruses. It is important for IS auditors to be aware of these risks and take measures to prevent and mitigate the spread of viruses on LAN servers.
