UDP and TCP use 1s complement for their checksums. Suppose you have the following three 8-bit bytes: 01010011, 01100110, 01110100. What is the 1s complement of the sum of the 8-bit bytes? (Note that although UDP and TCP use 16-bit words in computing the checksum, for this problem you are being asked to consider 8-bit sums.) Show all work. Why is that UDP takes the 1s complment of the sum; that is, why not just use the sum? With the1 s compliment scheme, how does the receiver detect errors? Is it possible that a 1-bit error will go undetected? How about a 2-bit error? Jim Kurose and Keith Ross,"Computer Networking – A Top-Down Approach", Addison-Wesley, Seventh Edition, 2017.

You are working as a security analyst in a company xyz that owns the whole subnet range of 23.0.0.0/8 and 192.168.0.0/8. while monitoring the data, you find a high number of outbound connections. you see that ip's owned by xyz (internal) and private ip's are communicating to a single public ip. therefore, the internal ip's are sending data to the public ip. after further analysis, you find out that this public ip is a blacklisted ip, and the internal communicating devices are compromised. what kind of attack does the above scenario depict?
