What does sensitive authentication data include?

Sensitive Authentication Data: Security-related information including, but not limited to, card validation codes/values (e.g., three- digit or four-digit value printed on the front or back of a payment card, such as CVV2 and CVC2 data), full magnetic-stripe data, PINs, and PIN blocks) used to authenticate cardholders …

What is the purpose of sensitive authentication data?

Sensitive authentication data, aka SAD, in PCI compliance is data used by the issuers of cards to authorize transactions. Similar to cardholder data, PCI DSS requires protection of SAD. Additionally SAD can’t be retained (stored) by merchants and their payment processors.

How is data encrypted on a server?

Most modern operating systems (like Linux or Windows Server) provide the capability to encrypt their disks in their entirety. This is accomplished with symmetric encryption whereby there is a key or passphrase that a computer operator has to enter when the disks are encrypted and when the system boots to allow access to the data.

How does SSL encrypt data from server to client?

The HTTP data is not always encrypted with public key of the Server, in order to send it to the Server. The public key of the Server is just used in the beginning (handshaking protocol) to establish a secure key, for Secure key encryption (Symmetric encryption)

When do I need to enter encryption passphrase?

When full-disk encryption is enabled on a physical (non-virtualized) server, remember that an operator – a human being – will need to type the passphrase into a console whenever the system starts up. For database-level encryption, the passphrase will need to be entered when the database starts up.

What happens when data is encrypted at rest?

Encryption of data at rest provides little protection against intrusions in which a hacker gains remote privileged access to a running server in which the passphrase has already been entered. Even more so, if the applications that access the encrypted files or databases (web applications,…
