QUESTION 1

1. How does a firewall protect a computer network from unauthorized access?
1. Discuss the difference between types of firewalls.

Expert Solution

A firewall is a network built to prevent unauthorized access or even from a personal network. One can easily execute a firewall in any of the hardware or software form or by combining both.

Firewalls help in preventing unauthorized accessors by accessing personal networks connected to the internet primarily intranets. All information reaching or leaving the intranet passes through the firewall, which evaluates each and every message or information and keeps barriers at those that do not meet the restricted security norms.

Differences between Types of firewalls are as follow:

-Packet filtering: in this type of firewall, the system evaluates each and every package passing into or clearing out the network and then decide to accept or reject it based on user-defined rules.

-Circuit-level gateway implementation: This procedure is basically applied on safety tools when a TCP connection is ascertained and once the connection is made between them, bundles can stream between the hosts without even any further checking.

1- Is there such a thing as an ethical reason for unauthorized access to a computer system? 2- One way to secure a network from attack is by blocking all incoming traffic. But is such a measure practical? Imagine running a network in different types of organizations (a bank, a university, and others). Would this be the ideal way to protect the organization's network from attack? Why or why not?

In a Wi-Fi network, data packets are transmitted between a laptop computer and the access point. Since the transmission is wireless, errors can occur that may render the packet useless, so, when received in error, the packet is discarded. As a protection for errors, an acknowledgement is expected, and if the packet is received in error, it is retransmitted, until correctly received. Consider that the probability that a packet is discarded is p=0.6. (a) What is the probability that the...
