What is required for a Nessus scanner to function correctly within a network?

• A. A minimum of two scanners must exist.
• B. Port 8834 must be open.
• C. A unique IP range must be assigned.
• D. Only static IPs must be used.

Answer: (B)

For a Nessus scanner to function correctly within a network, having port 8834 open is crucial. This port is the default for the Nessus web-based user interface, which allows users to configure scans, view results, and manage policies. Without access to this port, users would be unable to interact with the Nessus scanner effectively, rendering it unable to provide the necessary compliance assessments and vulnerability scanning services. The availability of this port is essential for communication between the scanner and the users or systems that need to access it. Therefore, ensuring that port 8834 is open aligns with the operational requirements of the Nessus scanner and is vital for its functionality within the network.
