A replay attack is a network security breach where an attacker intercepts and retransmits a valid data transmission to trick a system into unauthorized operations. This type of attack exploits the lack of temporal authentication in protocols, making it crucial to implement mechanisms like timestamps or nonces to prevent such vulnerabilities.

Protocols are formalized rules and conventions that govern the exchange of information between systems, ensuring interoperability and communication efficiency. They are fundamental in various domains, including computer networks, where they define the syntax, semantics, and synchronization of communication processes.
