Run ipconfig on a Windows device or ifconfig on a Mac to find your Wifi adapter IP address. Exchange IP addresses with a friend (you will scan each other) and put your friendβs IP into the Welcome to Nessus Essentials dialog. When you click Next Nessus will begin the host discovery step, making sure that the IP address you put in actually corresponds to an active host. Click the checkbox next to the host once it shows up in Host Discovery and run the scan. Youβll notice the status is Running while the scan is being performed.
Once the scan is complete, take a look at the summary of vulnerabilities in the Hosts tab. How many non-info vulnerabilities are there in each category (Low, Medium, High, Critical)?
