Which component of OpenVAS is responsible for running the actual vulnerability scans?

The Greenbone Security Assistant (GSA)

The Network Vulnerability Test (NVT) feed

A security engineer needs to write a custom NASL script to check if a specific file (e.g., /etc/issue) contains the string 'Ubuntu 20.04' on a remote Linux host. The scan will run with SSH credentials. Which NASL approach is appropriate?

Use the 'http_get' function to request the file over HTTP and check the response body.

Use the 'get_kb_item' function to retrieve the file contents from the Knowledge Base.

Use the 'find_file' and 'read_file' functions to locate and read the file, then use 'egrep' to search for the string.

Use the 'telnet' function to connect to the host and execute 'cat /etc/issue'.

A network engineer monitors a 1 Gbps link and notices that utilization is consistently at 85% during business hours. The engineer wants to determine whether this is normal or indicates a potential issue. Which additional metric would be most useful for this assessment?

Total bytes transferred per day

When using iftop to monitor network traffic, what does the output primarily display?

Historical bandwidth trends over days

Bandwidth usage per network interface

Bandwidth usage per host-to-host connection
