The Secure Enclave is a dedicated security feature found in many modern devices, such as those made by Apple. It provides a separate area within the main processor to store sensitive information, like passwords and biometric data, securely. This isolation helps protect the data from unauthorized access, even if the main operating system is compromised. The Secure Enclave uses advanced encryption techniques to ensure that the data it holds remains confidential. It operates independently from the main system, allowing it to perform tasks like secure booting and cryptographic operations without interference. This enhances the overall security of devices and user information.
