SolarWinds® Port Scanner is a standalone free tool that can be used in various ways to identify the ports running on your network. It also helps unveil network vulnerabilities.

This versatile tool has many applications. Check out the ideas shared in this post, and let us know in the comments below how you use Port Scanner.

Idea 1: Use Port Scanner to run a security analysis

A security engineer would like to see how vulnerable his network is by performing an analysis of open and closed ports within his network. By running SolarWinds Port Scanner, he is able to scan IP addresses and their corresponding TCP and UDP ports. In doing so, he can verify if the ports that are supposed to be filtered are, in fact, filtered.

Once he establishes whether the corresponding ports are open, he can run a security analysis using Port Scanner and receive the status of all the TCP and UDP ports on his network. If he finds an open port that is not supposed to be open, he can go into his firewall or router to disable traffic on that port.  

 

Idea 2: Run the CLI to export results

Network administrators must understand the peaks of IP usage within their network to see if they will still have IP addresses available during peak hours. To achieve that, the network administrator must run recurring scans to see the differences in IP usage.

Using Windows® Scheduler to run the command line interface (CLI) of SolarWinds Port Scanner every 15 minutes, network admins can export the results to a CSV file. After that, he can run a PowerShell® script to compare the results from all of the CSV files. This will give him a clear understanding of IP usage within his network, which is critical to his job. Without this information, it is nearly impossible to maintain a secure network with optimal performance.  

 

Idea 3: Use Port Scanner to detect rogue devices

Network administrators need to know if only whitelisted devices are connecting to their Wi-Fi network. To achieve that, he needs to run recurring scans to see the differences in host names and MAC addresses. 

To do this, the network admin can use the Windows Scheduler to run the CLI of SolarWinds Port Scanner every 15 minutes and export the results to an XML file. He can then run a PowerShell script to compare the results from all of the XML files, which will give him a clear understanding of the devices connecting to his network. If he finds any rogue devices, he can simply disable them from his wireless controller.
