'Data in use' refers to data that is actively being processed by applications, services, or the operating system within system memory (RAM). It's important because it is often in a decrypted state, making it vulnerable to unauthorized access or attacks, such as those by malware or an actor with root privileges. Therefore, securing data in use requires different strategies compared to protecting data at rest or in transit.
