- For a network to be effective, there are three criteria that must occur. Please explain your choice in a few short sentences in your own words.Many services like, for example email and chats, are now beingdone over hbp and hbps protocols. Now network security admins have aproblem in the sense that these services are increasingly encrypted withsophis8cated technologies, and the ability to process packets goes down.Let us assume that you are one such admin. Your company (rightly so) doesnot want you to write programs execu8ng on employee computers tomonitor what employees send and receive over the Internet due to privacyexpectations. Things like capturing user screens, key stroke loggers are notallowed. What you can monitor though is router/ firewall traffic, since thatis off limits to employees. In this case, do you completely give up loggingpackets at router side due to encryption, or is there some use to logging IPpackets at the router for security purposes? Please justify keeping commonabacks we saw in class in mind. Recall how a packet at the router looks likebelow. Payload is the actual data portion (most likely…There are three conditions that must be met for a network to be considered successful. Give me a quick rundown in your terminology of what one is.
- For a network to operate efficiently, what three things must be true? Can you give me a quick summary of what one is?Assume Alice and Bob are exchanging packets through a computer network.Suppose Trudy inserts herself in the network such she can catch all packets transmitted by Alice and send anything she wishes to Bob, and vice versa. List some of the bad things Trudy can do from here.For a network to operate efficiently, what three things must be true? Is there any way you could provide a basic summary of what one is?
- What are the three things that absolutely have to occur before one can consider a network to be successful and effective? If you could, could you perhaps clarify to me what you mean when you say "one"?Determine the three critical components of a network that ensure its smooth operation. In that time, please tell me all you can remember learning about one of them. What three components must a network have in order to operate optimally? What can you tell me, in your own words, about one of them that happened within that time frame?What is the distinction between blocking and nonblocking with respect to messages?

Mary In the above scenario, assume John is the Attacker (10.0.0.1), Alice is connected to the internet (11.0.0.1) and Mary is also connected to the internet (12.0.0.1). Indirectly John wants to send some unnecessary packets to Mary and disturb her. In this case.... 1) What type of Attack John as to use? 2) What type of Attack does Mary will face? 3) What is the role of Alice in this scenario? 4) Does the attack choose by the John will affect Alice too?We indicated that the goal of any communications is that the received information should “equal” the transmitted information. Give an example application where:The received information needs to be “exactly equal” to that transmitted. Discuss why that is?
