Which information security goals are important for an e-commerce system to meet?

The focus of e-commerce systems must be on goals that protect the data and the overall system. Data integrity ensures that the information being processed and stored is accurate and reliable. This means that customers can trust that their transactions are secure and that their personal data has not been tampered with. Availability refers to the system's capacity to ensure that authorized users have access to the data and services when needed. This is crucial in an e-commerce environment, where downtime can lead to lost sales and damaged customer trust.

In this context, the importance of data integrity and availability aligns perfectly with the fundamental goals of information security within an e-commerce framework. Therefore, selecting the option that outlines these aspects identifies the core security measures that need to be prioritized for effective operation and customer confidence. Options that mention penetrability or materiality do not directly relate to safeguarding the authentication and data trust required in e-commerce.
