You should test the network by ARP spoofing and write your findings in the report. Then, we looked at the topic of testing the network by using custom packets. The network disassociation attack is similar to the ARP cache poisoning attack, which was also explained. Half-open, FIN scan, and ACK flag scans are special types of scanning that we touched upon too. Lastly, ping of death, which is related to the DDOS attack, was explained.
