What is Non-Repudiation in Cybersecurity | Definition and Meaning

Non-repudiation in cybersecurity is a type of guarantee that a transaction or action has taken place. It prevents the parties involved in the transaction from denying that their actions and the transaction ever occurred. This is accomplished by using digital signatures, cryptographic timestamps, and other forms of digital evidence to prove the transaction or action took place. Non-repudiation is a critical component of cybersecurity as it helps to ensure the integrity of transactions and to protect organizations from cyberattackers who might otherwise deny any involvement in the attack.
