Companies providing, creating, or providing services may only store sensitive authentication data if they have legitimate business needs. Organizations that offer payment cards, services, or assistance providers and control sensitive authentication data as part of the card’s issuing.

Sensitive authentication data consists of full-track data, validation code or value, and PIN code. If you receive sensitive authentication data, make all data irreversible and unrecoverable after authorization is complete. PCI DSS Requirement 3.2: Do not store sensitive authentication data after authorization, even if it is encrypted. Repeat the quarterly process to identify and securely deleting stored cardholder data that exceeds the set retention period.Define actions to delete data when data is no longer needed securely.Create specific retention requirements for cardholder data.Limit the amount of data retention and retention period to the time required for legal, regulatory, or business requirements.The basic precaution you can take to store and manage your cardholder data will be if you do not need it, do not store it. Secure deletion methods may ensure that data is not received and deleted when it is no longer needed. This method can be either manual, automatic, or a mixture of both.įor example, a programmatic procedure can be used to find and remove data or to review data storage areas manually. Identifying and removing stored data that has reached the specified retention period prevents the over-processing of data no longer needed. See Also: What are the PCI DSS Data Retention and Disposal Requirements?
To identify acceptable data retention criteria, an organization must first recognize its business needs and legal or regulatory responsibilities related to the type of data relevant to or held in its sector. It is necessary to understand and know where the cardholder data is stored to be erased or removed when it is no longer needed. Only the primary account number or PAN, expiry date, cardholder name, and service code can be stored in an unreadable format after authorization. See Also: Card Hunting: Finding Card Data For PCI This data can then be destroyed or deleted safely when it is no longer needed. PCI DSS Requirement 3.1: Keep cardholder data (CHD) storage to a minimum by applying data retention and destruction policies, procedures, and processes.Ī formal policy on data retention defines which data should be stored and where the data is located. Let’s take a look at all the sub-requirements in PCI DSS requirement 3. If you do not need such sensitive data for your organization’s business needs, do not store it. This requirement has the main purpose of minimizing all risks associated with storing cardholder data. It specifically aims to protect primary account numbers (PAN) and sensitive authentication data (SAD) using hashing, truncation, or encryption methods. PCI DSS Requirement 3 concerns the protection of stored data. Primary account numbers (PANs) should not be sent explicitly using end-user technologies such as e-mail or messaging.

For example, cardholder data should not be stored among risk minimization methods unless it is necessary.īesides, if the full primary account number (PAN) is not required due to business requirements, the cardholder data must be truncated or masked. Such methods should also be considered opportunities to secure stored sensitive data and reduce potential risks. See Also: How do I Protect the Stored Payment Cardholder Data? Data cannot be read and used by attackers if they circumvent other security checks and access encrypted data without correct encryption keys.
Security mechanisms such as encryption, truncation, masking, and hashing are critical components of cardholder data protection. PCI DSS Requirement 3: Protect stored cardholder data PCI DSS Requirement 3.7: Ensure that security policies and operational procedures are documented, in use, and known to all affected parties to protect stored cardholder data.
