Q.1 Explain the fundamental objectives of the Network Security.
Answer:
Network security refers to the process of safeguarding the network's infrastructure from illegal access. Through the use of software and hardware technologies, a set of rules and configurations is designed to safeguard the integrity, confidentiality, and accessibility of computer networks CITATION GAM05 \l 1033 (Marin, 2005). Network security attempts to accomplish several key objectives. Confidentiality, Integrity, and Availability are the fundamental objectives of network security. Confidentiality is intended to ensure that only authorized individuals and computer systems have access to and view confidential information and data on a network. Integrity, as a network security objective, attempts to ensure the accuracy and reliability of data on the network. As a core goal, availability ensures that data and network resources are always accessible to authorized users when they need them.
Q.2 What do you mean by Message integrity. How to check the integrity of a message?
Answer:
It is vital to understand message integrity when it comes to the security of communications through networks and computer systems. Message integrity verifies the validity of the message being transmitted. This means that message integrity assures that the message is not altered or tampered with during transmission. The concept of message integrity extends further to ensure that no data is modified during transit. Typically, the hashing algorithm implements the concept of message integrity CITATION Set19 \l 1033 (Nielson & Monson, 2019).
