Southern New Hampshire University Lab: Closing Ports and Unnecessary Services Prompt In the lab section, "Closing Unnecessary Ports and Services," Step 26, type your name after the command prompt and take a screenshot of the output of the scan of port 80 (www) on the Windows machine after closing HTTP services. Closing unwanted ports and communication mediums is essential to network hardening. Why is this essential and how does it help with network defense? Using an adversarial mindset, how can you test to make sure only needed ports are open? What tools would you use?

It is important that these ports are monitored and managed strictly to avoid an attacker gaining easy access to the network. These practices help with network defense because they minimize the amount of attack surfaces that attackers can potentially take advantage of to launch attacks on a network.[Insert short response here.] Using an adversarial mindset, I would use port scanning services like nmap like an attacker would. With these tools I could identify if any un-needed ports are open on the network. [Insert short response here.] 2
