What are some concrete objectives and how much work do you think is involved? Yes I have thought more about the project as well searching and reading research papers so that I can get overview and understand the concepts in detail. I would measure it as it will help me to learn the skills of networking and also would give me a habit to read research papers and learn more about technologies. Currently, I am not sure the amount of work involved as I am still searching and reading papers and gathering as much information I can get. 2. For the APT1†¦show more content†¦Also, the attackers used Chinese keyboard to attack the users and used Chinese language which may help the cyber authority to trace the IP of the attacker and the region of the attacker. 3. What is information entropy? Why do you want a lot of entropy in your password? Information entropy is the average amount of information contained in each message received. Here, message stands for an event, sample or character drawn from a distribution or data stream. Basically, it tells us how much information is there in an event. In general, the more random the event is, the more information it will contain. Entropy thus characterizes our uncertainty about our source of information. The source is also characterized by the probability distribution of the samples drawn from it. The idea here is that the less likely an event is, the more information it provides when it occurs. The concept of entropy was created by a mathematician. He was named Claude Elwood Shannon. Entropy is average information, it is also measured in Shannons, nats, or hartleys, depending on the base of the logarithm used to define it. It has applications in many areas like lossless data compression, cryptography and other disciplines like biology, physics or machine learning. We need a lot of entropy in our password because of the following reasons: P r e e t V i m a l c h a n d J a i n P a g e | 2 Firstly, entropy is a measure of the disorder in a data sample which means â€Å"more the data
