Network Security

The word "network security" refers to a wide range of technology, devices, and processes. In its most basic form, it is a combination of rules and configurations that use both hardware and software technologies to safeguard the confidentiality, integrity, and accessibility of computer networks and data. Every company, regardless of sector, size or infrastructure, needs network security solutions to protect itself from the ever-increasing landscape of cyber threats that exist today.

What happens if an attacker tries to modify the Tag (the MAC) and the ciphertext while using a message authentication code (MAC)? Describe why such an attack could never be effective, given that the receiver might identify a modified tag or ciphertext.
What happens if an attacker attempts to tamper with the Tag (the MAC) and the ciphertext while the message is in transit? So, what ends up happening? Show us how and why this receiver will always recognize a changed tag, and explain why this attack is doomed to fail.
What results may be expected from the use of a message authentication code (MAC) in the event that an adversary tries to alter the Tag (the MAC) and the ciphertext while they are in transit? Please explain why this attack is pointless given that the receiver would be able to detect a modified tag or ciphertext. Thanks.

Please explain why this attack is pointless given that the receiver would be able to recognize a tampered tag or ciphertext. Thanks.
What happens if an attacker attempts to alter the Tag (the MAC) and ciphertext while the message is in transit? What transpires? Let us know how and why this attack will fail; that is, how and why this receiver will always be aware that the tag has been changed.
What happens if an attacker attempts to alter the Tag (the MAC) and ciphertext while the message is in transit? What happens? Let us know how and why this attack will fail; that is, we must show how and why this receiver will always recognize that the tag has been changed.
If an attacker changes the Tag (MAC) and ciphertext while using a message authentication code (MAC), what happens? Explain why this attack will fail as the recipient would recognize a changed tag or ciphertext?
What happens if an attacker attempts to modify the Tag (the MAC) and the ciphertext while the message is in transit while using a message authentication code (MAC)? Explain why this kind of attack will never succeed since the recipient would be able to recognise a changed tag or ciphertext.
When a message authentication code (MAC) is being used, what takes place in the event that an adversary tries to change both the Tag (the MAC) and the ciphertext? Explain why it is impossible for an attack such as this one to be effective given that the receiver may be able to see a modified tag or ciphertext.
What results may be expected in the event that an attacker attempts to change a communication while it is in motion by modifying the Tag (MAC) and the ciphertext? Explain why the recipient will never miss a changed tag or ciphertext and why this attack will not succeed.
What happens if an attacker attempts to alter the Tag (the MAC) and the ciphertext when a message authentication code (MAC) is being used? Describe why a successful attack like this would never be possible since the recipient might detect a changed tag or ciphertext.
When a message authentication code (MAC) is employed, what happens if an attacker tries to tamper with the Tag (the MAC) and the ciphertext? Explain why such an attack could never succeed, for example because the target could notice a difference in the tag or ciphertext.
