What is the default port for accessing the Nessus Scanner web console?

• A. 8080
• B. 8834
• C. 80
• D. 443

Answer: (B)

The default port for accessing the Nessus Scanner web console is 8834. This port is specifically designated for the Nessus interface, which allows users to manage scan configurations, view vulnerability data, and perform other administrative tasks related to vulnerability management.

Using port 8834 helps to differentiate Nessus from other web-based services that may run on more common ports like 80 (HTTP) or 443 (HTTPS), which are typically used for general web traffic. By default, Nessus runs its web interface on this specific port to accommodate secure communication and ensure that it’s distinct within the network environment.

This configuration allows organizations to open the required firewall ports specifically for Nessus, ensuring that connections can be made to the scanner for effective vulnerability analysis while maintaining a secure and organized network architecture.
