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? Response Nmap done: 1 IP address (1 host up) scanned in 13.68 seconds root@kali2 :- # nmap 192.168. 12.11 -p 80 Starting Nmap 6.49BETA4 ( https: //nmap. org ) at 2024-04-03 09:33 EDT Nmap scan report for 192.168.12.11 Host is up (0.00024s latency) . PORT STATE SERVICE 80/tcp closed http MAC Address: 00:50:56:8E: 42:54 (VMware) Nmap done: 1 IP address (1 host up) scanned in 13.72 seconds root@kali2 :~ # Michael Bolinsky [Insert screenshot here.] [Insert short response here.]Reducing the threat landscape is a primary duty for an analysis and one such way to accomplish this is by closing down these unwanted ports which effectively reduces the lanes of traffic into a protected network/system. [Insert short response here.]Testing of open ports can be accomplished using applications like nmap, zenmap, and other recon application types. This can allow mapping of a system for potential attacks. 2
