According to requirement 3.2, what action should be taken regarding sensitive authentication data after authorization?

The correct action regarding sensitive authentication data after authorization is to render all data unrecoverable. This requirement is addressed in the context of maintaining the security of payment card information and ensuring that sensitive data is not misused. Sensitive authentication data includes details such as full magnetic stripe data, card verification codes, and PINs.

By rendering this data unrecoverable, organizations mitigate the risk of data breaches and unauthorized access. This aligns with best practices in data security, emphasizing the importance of not retaining sensitive information longer than necessary, particularly after the authorization process is complete.

The other options do not comply with security guidelines; for example, storing sensitive data securely or encrypting it for future use contradicts the fundamental principle of not retaining such data. Additionally, sharing with authorized personnel is not permissible since even those authorized personnel do not need access to this data after the transaction is authorized. The focus is on preventing any potential misuse by eliminating the data entirely.
