In information security, confinement specifically refers to limiting the access and flow of sensitive data to ensure that it does not unintentionally leak or get accessed by unauthorized entities. This concept is crucial for safeguarding confidential information, such as personal data, intellectual property, and proprietary business information.

The focus on preventing sensitive data leaks is fundamental in ensuring that data remains within the boundaries of its intended use and access rights. Confinement strategies may include measures such as strict access controls, data classification, and auditing processes to monitor who accesses sensitive information and under what circumstances.

The other choices provided involve important security measures but do not directly encapsulate the concept of confinement. Restricting user access to data pertains more to access control principles, monitoring system performance relates to system health and optimization, and encrypting data stored on hardware is a method of protecting the data itself rather than managing its flow or access.
