Abstract: A computer system determines a first criticality relating to frequency of execution of computer programs, a second criticality relating to frequency of execution of transactions, a third criticality relating to a number of users who execute the transactions, a fourth criticality relating to programs that modify the database tables having a large change in data, and a fifth criticality relating to the amount to time that each computer program is executed and the amount of time that each transaction is executed. The system determines intersections among the criticalities, and assigns a weighted value to each of the intersections. The system determines an overall criticality for a particular computer program or a particular transaction. The overall criticality is a function of the number of intersections in which the particular computer program or the particular transaction appears and the weighted values assigned to the intersections.

Abstract: A system and method for securely transferring sensitive payment data across a system landscape. The system and method may utilize machine-readable media including program code stored therein executable by one or more processors to perform the transferring of payment data. The transferring of data includes generating and encrypting a data container to combine all sensitive payment data.

Abstract: A system and method for securely transferring sensitive payment data across a system landscape. The system and method may utilize machine-readable media including program code stored therein executable by one or more processors to perform the transferring of payment data. The transferring of data includes generating and encrypting a data container to combine all sensitive payment data. The encryption logic is configured to automatically transfer keys between systems.
