Cryptographic Failures occur when sensitive data isn’t properly protected during storage or transmission. This includes using outdated encryption algorithms, weak key management, or failing to encrypt at all. It often stems from misconfigurations, poor implementation, or skipping encryption due to complexity. These failures can lead to serious data breaches, identity theft, and loss of trust. Proper encryption, secure key handling, and up-to-date protocols are essential to keeping data safe and compliant with regulations.
