Description: A ‘Key Escrow’ is a security mechanism that allows a third party to securely store a copy of a cryptographic key, facilitating its recovery in case of loss or compromise. This approach is fundamental in the context of Zero Trust security, where it is assumed that threats can arise both from within and outside the network. The central idea is that, by not automatically trusting any user or device, it is crucial to have secure and reliable recovery methods. A key escrow not only protects the integrity of information but also ensures that access to sensitive data remains controlled, even in adverse situations. The main features of a key escrow include the encryption of stored keys, robust authentication for accessing them, and the implementation of access policies that limit who can retrieve the keys and under what circumstances. This approach has become increasingly relevant in a world where security breaches are common, and organizations seek to effectively protect their digital assets.
