Closing unwanted ports and communica on mediums is essen al to network hardening. Why is this essen al and how does it help with network defense?
[Closing unwanted ports and network medium helps keep any sort of loopholes clear from attackers getting in. It also helps to keep the network more protected. Keeping unused ports open leaves the network vulnerable for attackers to easily get in due to these being less monitored than they should. If they are clear it will help to keep the network safer.

Lab: Closing Ports and Unnecessary Services
Prompt
Response
Using an adversarial mindset, how can you test to make sure only needed ports are open? What tools would you use?
L would first install a port scanner tool that will scan for open oorts. Once the scan is complete, I will take note of what ports
are in use and what is using them and then any un-used ports I will make sure to close them to eliminate an attack. I would use Nmap port scanner to check for opened ports as well as netstat to see any sort of rules or blocks on the firewall and network to make sure that I don't close or block ports that are needed.
