Research methods for hardening PFSense. 

Using the virtualized PFSense system created  harden the   PFSense system using Snort.

1. Start the Snort service.
2. Update Snort and download     the latest community rules.
3. Ensure that you have configured     Snort to detect port scans.

Using the Kali VM from Topic 3, run another port scan. 

Using screenshots of the results, explain if Snort detected the port scan.

Create a 300- to 500-word step-by-step instructional guide detailing   how to detect scans using snort. Make sure to:

1. Explain what hardening is, what Snort does, and why it is     being used in this scenario.
2. Explain any other methods by     which PFSense can be hardened. 
3. Include at least five   screenshots.
