 Currently i have been thinking of projects that i can combine with my other existing courses to help save time and effort. The main class i have in mind is datacomm. Matt's guidelines were that the project had to have some sort of inspection and processing of data from a source. My first idea was to use wireshark & snort to filter local area network traffic and identify a specific pattern of packets in conjunction with a specific attack type. I am currently thinking of using ARP spoofing as the pattern i want to detect. This is for two reasons. first and foremost ARP spoofing is an extremely simple yet effective attack that works on a LAN level only. Being able to avoid this easy attack on your local area network can save many headaches. Secondly ARP packets are extremely unique in comparison to others. This would allow for very easy filtering and capture of these packets only.  Currently i have been thinking of projects that i can combine with my other existing courses to help save time and effort.

 +My arp spoofing project is under way! Currently I have two Windows 10 virtual machines set up and running cain and able. This is the program I will be using to do the ARP spoofing attacks. I have been looking into Linux options for ARP spoofing as well as creating my own programs to do this. For now this is the quickest option. The next step will be to set up a service that is vulnerable to ARP spoofing to demonstrate its uses. For this i have been considering an apache web server using http instead of https. This would allow me to see if the spoofing actually worked to capture the unencrypted traffic sent between the web server and the spoofed host. to capture this traffic i will use wireshark. This will give me a pcap format file to sift through and find arp packets. From there i will creat a script that can take in a MAC address and search for arp packets that match the address. As i write this i am thinking of issues with this and maybe i need to do some more brainstorming and testing. BLAGHHH.
