About this interactive

A key management system is any system for creating, storing, distributing and managing keys, and it is not always about technology. The lesson pictures a valet taking your car keys, or a lock box holding the keys to the equipment lockers. Keys come in three kinds. A physical key gives physical access: a key to a door, a cabinet or a rack. A credential proves identity to a system: a username and password, a PIN, a service account. A cryptographic key is used in cryptography: a public key, a private key, a pre-shared key, a symmetric key, used to encrypt, decrypt or sign. A trusted platform module works as a hardware-based part of a key management system, assigning keys, encrypting and storing them. To sort a card, ask what the key is for: opening something physical, signing in to a system, or doing cryptography.

Key terms

Key Management
The administration of cryptographic keys throughout their lifecycle, including generation, storage, distribution, and destruction, to ensure secure cryptographic operations.
Trusted Platform Module
TPM
Trusted Platform Module is a dedicated hardware security chip embedded in devices that provides a hardware root of trust for secure boot, cryptographic key storage, and platform attestation, protecting sensitive keys from software-level compromise.
Default Credentials
Factory-set usernames and passwords that ship with network devices, applications, and services. Default credentials must be changed immediately upon deployment because they are publicly documented and frequently targeted by automated attackers.
