When using a MAC, an attacker attempts to change both the Tag (the MAC) and the ciphertext (message authentication code). I'm scared of the potential consequences. If the attack succeeds, the target will always be able to spot a tampered Tag or ciphertext.

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.
